hey boys and girls00:00:05
uh today is uh motor day00:00:08
and uh what we're going to do is we're00:00:10
going to start off with the inverter00:00:12
this00:00:13
is one of the motors off the tesla00:00:16
model s plaid00:00:18
this is the inverter00:00:20
let's take this off00:00:23
and let's look at this00:00:25
this00:00:28
like the sign says is the model 3 front00:00:35
this is the model y front00:00:42
this is the model 3 rear00:00:50
and this00:00:53
is the model y rear00:00:59
now00:01:01
for those of you who00:01:03
aren't engineers00:01:05
this is good engineering00:01:08
this is forward and backward compatible00:01:13
this is what i like to see when i see00:01:16
products00:01:17
manufactured00:01:19
and designed00:01:20
and put in the hands of the people who00:01:22
are going to basically live with this00:01:24
because quite frankly every one of them00:01:28
can take the same00:01:31
inverter package00:01:33
this00:01:34
by the way i'm going to show you right00:01:36
now has a little note on it00:01:38
as soon as i find it00:01:40
right there00:01:44
model 3.00:01:48
the other ones will say model 3 as well00:01:50
because this00:01:52
is the standard that they have inside00:01:54
their organization and because00:01:57
this this board is so advanced00:02:00
it's going to be around for a long time00:02:03
all they have to do is modify some of00:02:04
these chips but at the end of the day00:02:07
this is a really good design00:02:09
let's go and look at the rest of the00:02:10
motor so before we get started let's00:02:13
zoom zero in on this a little bit00:02:15
this is the board that came off of the00:02:18
model y00:02:19
you'll notice that the insignia where it00:02:21
says model 3 right there00:02:24
is in a different location the model 300:02:27
board and the model y board are very00:02:30
very very similar only a few components00:02:32
change00:02:33
if we look at the difference between00:02:36
what we saw00:02:37
over00:02:39
on the other00:02:40
on the other inverter00:02:42
versus00:02:44
versus this inverter00:02:46
you can see that there are things that00:02:48
are in different locations00:02:50
but a lot of it looks identical to the00:02:53
average person00:02:55
like you can see there's a couple of00:02:56
capacitors there that aren't here00:03:00
these boards are very very similar and00:03:03
and they're made00:03:04
to be modified a little bit00:03:06
so that uh so that tesla can00:03:10
upgrade over the uh over the time that00:03:14
that the the product will be in the00:03:15
marketplace00:03:17
and if you look00:03:18
you can see00:03:19
this is one of the other inverters00:03:22
and you can see that apart from00:03:24
oops wrong one00:03:26
this is one of the other inverters00:03:27
that's from uh from the from the model00:03:30
from the00:03:31
from the plaid00:03:32
and you can see that they're identical00:03:35
these are identical00:03:37
regardless of whether it's a front motor00:03:38
a rear motor it doesn't matter it's00:03:40
identical00:03:42
so with that00:03:46
let's talk about a little bit about00:03:49
uh the the motors and the casings00:03:52
themselves so ben's with me00:03:54
so i don't screw up and um and we're00:03:57
gonna talk a little bit about the00:03:59
integration of these two motors and00:04:00
we've got them sitting right in front of00:04:02
us uh00:04:03
ben why don't you jump in and uh00:04:05
all right yeah you can do that thanks00:04:07
sandy yeah so we have the rear motor00:04:10
assembly that's sitting at the front00:04:12
side of the table right now00:04:13
they have two motors and two inverters00:04:16
that are all connected into00:04:19
into one housing assembly so when it00:04:20
gets mounted into the vehicle it's going00:04:23
in as one unit the00:04:24
gearbox housing has been integrated into00:04:28
the stator housing so that this is now00:04:30
one piece00:04:32
they share a common00:04:35
gearbox housing on the inner side00:04:37
which allows them to make this a very00:04:39
compact unit00:04:41
there are00:04:42
two different oil pumps on the two00:04:45
different stators to keep both of them00:04:47
cool then there's another oil pump00:04:49
that's00:04:50
located in this mid center casting00:04:53
what we can do here is00:04:55
maybe show off00:04:58
the filter the cooler and00:05:00
and one of those pumps in here this is00:05:02
the front motor that we've taken out we00:05:05
have the oil filter which there is just00:05:07
one oil filter on the rear two motor00:05:10
assembly as well so one oil filter up00:05:12
for front they have one heat pump and00:05:14
then the heat exchanger00:05:16
the00:05:17
i said i said heat pump i meant oil pump00:05:20
i'm sorry they have one oil pump up00:05:22
front and one heat exchanger so each00:05:24
motor on the rear has00:05:26
a the same pump and the00:05:29
uh the same00:05:31
heat exchanger00:05:32
you know one of the things that that we00:05:34
noticed that we really like is00:05:37
if we look at00:05:38
the the way the housing is put together00:05:41
you've got a bolt that comes in from00:05:43
this direction00:05:44
passes through that section and then00:05:46
bolts into00:05:48
into the the rear00:05:50
housing for the stator00:05:52
this is a really good way of making00:05:54
things happen because in order to make00:05:56
bolts work really well you have to00:05:59
torque them and then put them into yield00:06:01
so you actually stretch the bolt so it00:06:03
turns into a spring00:06:05
this this arrangement here00:06:08
having everything coming through in one00:06:10
direction and not having a bolt coming00:06:12
here and then tying into that center00:06:14
section or from there and into the00:06:16
center section that's a really good idea00:06:19
bolt stretch is really important00:06:20
especially on aluminum products so00:06:23
we were really happy to see uh some see00:06:25
what's going on with that00:06:27
yup and00:06:28
one other thing that they did integrate00:06:30
here is they don't have a differential00:06:32
on the rear they have the two motors so00:06:33
they're doing torque vectoring each00:06:35
motor is driving one of the rear wheels00:06:38
it's not like the front where there is a00:06:39
differential00:06:42
in here so that they're able to drive00:06:44
both of the wheels and you don't get any00:06:46
skid when you're going around the corner00:06:47
any chirping of your wheels00:06:49
they are using the same oil in these00:06:51
that they were using in the 3 and y as00:06:53
well00:06:54
so it's going down their production line00:06:56
they don't have something else they have00:06:57
to00:06:58
pump into these it's getting the same00:07:01
the same oil and then they did change00:07:04
the gear ratio on these they've lowered00:07:06
them a little bit the model s has a 7.5400:07:09
to 1 gear ratio when the model y it was00:07:13
at00:07:15
nine 8.996 to one so it's00:07:17
it's been reduced quite a bit00:07:20
so let's look at one other thing that i00:07:22
uh i was surprised to see happily surprised00:07:25
to see00:07:26
and that's over here00:07:33
yeah i just didn't want to run over the00:07:35
tools here there we are00:07:37
this is a00:07:38
this right here is a mirror finish00:07:41
um there are a lot of ways of making00:07:43
that happen00:07:45
but the best way is something called00:07:47
roller burnishing and that's what i00:07:48
think is going on here now this is where00:07:50
the bearings fit and bearings have to00:07:52
have a very accurate00:07:56
and precise uh00:07:59
hole to be pushed into00:08:01
this roller burnishing is um if that's00:08:04
what it is and i think it is00:08:06
this is a fabulous way of putting00:08:09
putting00:08:10
bearings into a housing this will tell00:08:13
me this will give me00:08:15
a dead accurate diameter to shove those00:08:18
bearings in and the bearings like it00:08:20
when they're pressed in and they want to00:08:23
be just the right snugness in order to00:08:26
make this work00:08:27
this is a something i haven't seen uh i00:08:31
haven't seen usually the only time you00:08:33
see this is a00:08:34
like in brake components like the the00:08:36
master cylinder is done using roller00:08:39
burnishes because it it gives you it00:08:41
compresses the uh00:08:43
it compresses all of the tool marks and00:08:46
whatnot flattens it out and makes it so00:08:49
that it's actually00:08:51
forged cold forged to uh to give you00:08:54
this surface and it's really really00:08:56
something i really really am impressed00:08:57
with this00:08:59
so00:09:01
all right we'll take a look at a couple00:09:03
of other things that we have here in the00:09:05
housing00:09:06
we're gonna look where the inverter00:09:08
mounts into the housing next00:09:10
so we have00:09:11
this cast in feature here00:09:14
that is for the bleed resistor that is00:09:16
on the inverter so that's a heat sink so00:09:19
it's using some of the cooling that's00:09:21
inside the motor that's cooling the00:09:22
stator to help cool the inverter as well00:09:26
and then one other thing that they've00:09:28
done with this unit that tesla hasn't00:09:30
done before is they are now side00:09:31
mounting their inverter00:09:33
which means you have the stator that's00:09:36
right here00:09:37
typically they mount on the end of this00:09:40
and kind of a cap but because of their00:09:42
width constraints because they have two00:09:43
motors that are next to each other00:09:45
they've had to move their inverter to00:09:46
the side00:09:48
um and one of the penalties from that00:09:50
you can see this piece here is still in00:09:53
that is where the inverter will connect00:09:56
to this bus bar00:09:58
and this bus bar this is the other side00:10:00
so it's not going to sit in here the00:10:02
same way but this bus bar is going to go00:10:04
and connect to your stator00:10:06
the leads that they have on their stator00:10:08
typically connect straight to their00:10:10
inverter when you're able to end mount00:10:13
the inverter so they've had to00:10:15
add a piece00:10:16
but they kept the same inverter and the00:10:18
same inverter housing so it is00:10:21
it's a decision that they made to keep a00:10:23
common common component that's complex00:10:25
and just bring in a simple bus bar00:10:29
the one thing we also noticed was the00:10:31
gasketing there's no there's no rtv on00:10:34
anything00:10:35
uh for for this product all of them are00:10:39
our laminated gaskets so these are our00:10:43
gaskets that00:10:45
these are the premium gaskets00:10:47
you'll notice that that they've got both00:10:52
a metallic part in this case aluminum00:10:55
and00:10:56
and then gasketing material and an00:10:58
o-ring type of gasket or a half-o-ring00:11:00
kind of gasket that's molded on top we00:11:02
used to call this vulcanized in place00:11:05
i'm not sure what they're calling it now00:11:06
but but this00:11:08
this is uh like i say the premium way of00:11:11
doing it and the reason for that is00:11:12
because when i screw these bolts00:11:14
together00:11:15
i want to have them into yield that00:11:17
means that there's tremendous amount of00:11:20
force00:11:21
if i use an ordinary gasketing material00:11:23
it's going to flatten it out with this00:11:26
i will flatten the00:11:28
the gasketing material but this is going00:11:31
to act as a as a little bit of a shim to00:11:34
make sure that i don't crush it too much00:11:37
so that uh so that it it becomes00:11:40
ineffective if if you flatten uh just an00:11:44
ordinary seal00:11:45
it'll um it'll leak eventually so this00:11:48
is a really good gasket really kind of00:11:50
expensive but a very good gasket for the00:11:53
life of the product this is the gear00:11:55
million mile kind of gasket00:12:01
okay and then we're going to jump onto00:12:03
the stator to talk a little bit next the00:12:05
stators that they're using are the same00:12:07
ones out of the model y again tesla has00:12:10
gone with reusing components00:12:12
everywhere that they can00:12:14
so this is something that they're taking00:12:16
they're already producing00:12:18
hundreds of thousands a year and they're00:12:20
putting them into this vehicle00:12:22
it's a coil wound stator as you can see00:12:24
it's a three-phase stator they are again00:12:27
cooling through the channels in their00:12:29
laminates that are here00:12:32
and they are using00:12:33
using paper slot00:12:35
liners on the inside again very similar00:12:38
or the very same thing as the model y00:12:41
so it's things we've seen before and00:12:43
then they have a cooling ring00:12:46
that goes00:12:47
on top of this so this is where00:12:50
the oil would be pumped through to go00:12:53
through the channels in here to help00:12:55
cool00:12:56
the stator00:12:58
the same design and same architecture00:12:59
that they've had in their model 3 and00:13:01
model y motors all right and then this00:13:04
stator when it goes to get pressed in00:13:06
they they heat press this into place so00:13:08
they will00:13:09
cool the stator some they'll heat up the00:13:11
aluminum housing so the aluminum grows00:13:13
this will shrink a little bit put it in00:13:14
place then when they go to the same00:13:16
temperature it's a very tight fit to be00:13:19
able to get these out we have to cut the00:13:21
stator housing so it's it's effectively00:13:23
held in place without any fasteners it's00:13:26
not gonna it's not gonna go anywhere00:13:29
so right now what we see here is um the00:13:32
standard wound type of stator00:13:36
however00:13:37
at the end of the program we're going to00:13:39
talk or show you a little bit of00:13:41
something that we got from someone i00:13:43
don't know who but00:13:45
somebody sent us a little picture and um00:13:47
this is a totally different departure00:13:51
or a yeah a departure from the standard00:13:54
way that that tesla's been doing things00:13:56
and we'll give you a sneak peek at that00:13:59
right at the end of the program00:14:03
so00:14:04
now we've gotten through00:14:06
basically the housings the inverter00:14:09
the stator00:14:11
the cooling systems and whatnot00:14:14
let's move over here to the rotor and um00:14:17
i think the first thing that i want to00:14:19
do00:14:20
is give you an idea of something that uh00:14:23
really00:14:25
really surprised me00:14:28
um00:14:30
this00:14:31
this uh this is the rotor and you can00:14:33
see that it's got a wrap on it the wrap00:14:36
is um is made out of uh00:14:39
out of uh carbon fiber00:14:41
and um this is what we would call a00:14:44
winding00:14:45
it it's just uh a bobbin basically and00:14:48
it gets uh covered with carbon fiber00:14:51
and epoxy it's a prepreg i'm sure and um00:14:54
and when it's done it's done00:14:56
now um00:14:58
that's something we've never seen before00:15:00
and that that's kind of amazing00:15:04
but then we put the green paper on here00:15:07
and00:15:08
that00:15:09
is not what i was expecting to see00:15:12
if you remember before i was telling you00:15:14
that all of the different laminates are00:15:16
slightly skewed00:15:18
so that you don't get pulsing00:15:21
this one00:15:23
is uh00:15:24
is doing something magic00:15:26
this is00:15:27
not00:15:28
skewed00:15:30
this is in line and uh00:15:33
and i've driven that car quite a bit and00:15:35
i detected no pulse whatsoever00:15:38
i'm00:15:39
astounded i guess it'd be the right word00:15:41
i i've never seen anything like this00:15:43
before uh on a on a high speed high00:15:46
power motor and i think it's because00:15:49
tesla's invented some new physics or00:15:52
something the one thing on here that i00:15:54
would suggest00:15:56
because00:15:57
i look at this and i uh00:16:01
this isn't my this would not be my first00:16:03
choice00:16:05
i like the idea of the carbon fiber but00:16:07
i don't like the the winding00:16:10
but we worked with a company that that00:16:12
made the machines that make00:16:15
sweaters socks00:16:17
dresses00:16:18
and00:16:20
and that machine uh could00:16:22
knit um00:16:24
a winding00:16:26
if i was00:16:27
tesla00:16:28
i think i'd i'd probably go with that00:16:31
because i could take that carbon fiber00:16:33
then i could slide it over this will00:16:34
give you unidirectional00:16:37
you know this works only in one00:16:39
direction whereas if i had00:16:42
a knitted or a woven00:16:44
blanket that goes over the top of this00:16:47
i would get a lot stronger a much much00:16:51
stronger component so i like the idea of00:16:54
this being carbon fiber00:16:56
but i think that00:16:58
i think that there's a better way to get00:16:59
the job done00:17:01
the next thing that's kind of00:17:03
interesting is00:17:05
the laminates themselves now00:17:09
i've never seen anything that looks like00:17:11
that00:17:12
and00:17:14
these components here are00:17:17
a little different00:17:19
you can see00:17:20
the magnets go in between here00:17:23
and um and then you've got an end cap00:17:26
that holds it in place00:17:28
then you wind it with the00:17:31
with the carbon fiber00:17:33
i've never seen anything like this00:17:34
before00:17:36
and00:17:37
and so consequently what you're looking00:17:39
at00:17:47
and what we're looking at here is00:17:50
here's your laminates00:17:52
on the shaft00:17:53
here's the magnets by the way these00:17:55
magnets were all glued together00:17:58
they they don't come in little sections00:18:00
like this00:18:01
they come in a long bar00:18:04
and the this long bar goes into the00:18:08
laminates and basically they're held by00:18:10
these little cleats see these little00:18:12
tiny00:18:13
these little tiny cleats here that's00:18:15
what holds it in place00:18:17
now the the standard way of making00:18:20
a laminate case or the the traditional00:18:23
way that they've been using is by using00:18:26
mechanical stapling and you can see the00:18:28
little dimples here on this side00:18:30
and the little projections on this side00:18:32
and that's kind of like stapling them00:18:34
together to make a like a solid00:18:36
component and that solid component even00:18:39
though it's a whole bunch of how many00:18:40
laminates did you say there was00:18:42
there are00:18:45
529 laminates in each motor00:18:48
and that's a lot so the00:18:51
the statistics uh the00:18:53
the statistics on this are a little bit00:18:55
different than what we've seen in the00:18:57
past00:18:58
i've i've never seen anything quite like00:19:00
this00:19:01
we know that what they're going to do is00:19:03
they're going to press on the00:19:05
the laminates in one lump00:19:08
and then00:19:09
they're going to take these long magnets00:19:11
but they're not magnetized yet but00:19:13
anyway they'll take one these long00:19:14
magnets and put them in place00:19:18
i'm not sure how they uh they do what00:19:20
they do to make this work00:19:23
because they don't touch00:19:25
but maybe what they do is00:19:27
magnetize these and then drop these in00:19:29
place i'm not sure00:19:31
all i know is that what we're looking in00:19:34
the way of00:19:35
gauss equipment or sorry the the goss of00:19:37
this is uh phenomenal in comparison to00:19:40
uh00:19:41
in comparison to the model 3 or the00:19:45
or the model y00:19:47
and we're just finding out now00:19:50
so ben is finding out how how sticky the00:19:53
magnets are00:19:55
so anyway i'm going to turn it over to00:19:56
him so uh so anyway00:19:59
why don't you uh00:20:00
fill us in on all right so we'll take00:20:02
another look at what sandy was just00:20:04
looking at here with this rotor that00:20:06
we've partially put back together00:20:08
so we have two magnets in here we have00:20:10
our inner laminates that we've built in00:20:14
and then we've got these bridges that go00:20:16
on the top we're just gonna put this in00:20:17
so you can kind of see what it looks00:20:18
like when it's all together hopefully00:20:20
these stay kind of close to each other00:20:22
so we can00:20:23
show you what's here we'll00:20:25
pull the laminates apart a little bit my00:20:28
tool gets stuck as well but you can see00:20:30
that these are in here they don't touch00:20:32
on the outside here so they've removed00:20:34
that bridge that is on a normal00:20:37
normal laminate stack00:20:40
and that has allowed them to get much00:20:42
better00:20:44
power and torque00:20:45
from this rotor so they are they've00:20:48
patented this and they're claiming in00:20:49
the patent that they're actually getting00:20:50
a 25 increase in peak torque and peak00:20:53
power because of building their laminate00:20:56
stack this way and using00:20:58
using these to remove using these00:21:01
pieces to remove the bridge that was00:21:03
here00:21:04
so that's uh then they've also these00:21:07
magnets we set it during the maki video00:21:09
but these magnets are super strong again00:21:11
so we're gonna do a test we've grabbed00:21:13
some of our different magnets here in a00:21:15
little bit we're going to walk to the00:21:16
back and do a pull test to see how00:21:18
strong these magnets actually are give00:21:20
you guys some numbers more than just us00:21:22
saying this is really strong00:21:24
so we'll be doing that in a second00:21:28
and then00:21:29
is there anything actually yeah while00:21:30
we're on this um uh corey uh wants me to00:21:33
do the big sale so all right anyhow um00:21:37
we have a very limited number of these00:21:39
laminates obviously00:21:41
and uh and what we're going to do is00:21:43
we're going to be selling these they'll00:21:44
be online00:21:46
and00:21:47
like i said these are really unique i'm00:21:50
expecting that there's going to be a few00:21:51
people from the oems and people who make00:21:54
magnets that are sorry motors i should00:21:56
say that are going to be interested in00:21:58
in the laminates and maybe the and maybe00:22:01
the keepers as well but at the end of00:22:03
the day these will be up for sale00:22:06
shortly um i'm not in charge00:22:09
i'm not sure00:22:11
of any of that stuff all i can tell you00:22:13
is that corey wants me to let everybody00:22:14
know that we're going to be selling00:22:15
these00:22:16
oops and now what do we what are we on00:22:19
to next now we are going to hop back00:22:22
over uh to the inverter00:22:24
and something00:22:26
something that is00:22:28
new in this inverter sandy showed you00:22:30
kind of the highlights before but there00:22:32
is now a00:22:33
uh explosive charge with a couple of00:22:36
plungers here that are used to break00:22:38
these bus bars00:22:40
so we're going to go through we're going00:22:41
to set this up we've rigged up a test00:22:43
equipment and we're going to run this to00:22:45
see how see what it looks like so00:22:47
we will be setting that up right now you00:22:49
can see00:22:50
this is out of the model y00:22:53
the change in the bus bars these were00:22:54
solid bus bars on the outside00:22:57
the model s if you come over you can see00:23:00
that they are00:23:02
they have been shaped to allow them to00:23:04
break00:23:06
and so that will break this plunger will00:23:08
break the inner00:23:10
piece of the bus bar and then there is a00:23:12
fuse that connects the outer part so00:23:14
this fuse will pop once all the power is00:23:17
being ran through the outer portion so00:23:19
this is a00:23:20
third fourth fifth fail safe that tesla00:23:23
has installed to be able to cut power to00:23:26
the motors they have00:23:27
different safety features inside the00:23:29
battery inside the battery management00:23:31
system now they're adding another step00:23:33
in the inverter to physically00:23:35
cut power in00:23:37
in whatever situation they need to do00:23:38
that in00:23:40
so we're going to set this up we're00:23:41
going to set up some cameras and we'll00:23:43
hop behind the wall and we'll we'll pop00:23:45
this and see how it goes00:23:48
stay tuned okay so we're almost ready to00:23:52
try this out um00:23:54
these types of um explosive fuses are00:23:59
a little more exciting than uh than just00:24:01
having um you know something turned00:24:03
black00:24:04
so um we're going to uh we're going to00:24:07
ignite this00:24:08
and you're going to get a chance to see00:24:10
it but not with anybody else in the00:24:12
picture certainly not me anyway and00:24:14
you'll see that i've got the stator00:24:16
sitting on top of it00:24:18
that's there for a reason we're pretty00:24:21
sure that this is going to pop around so00:24:24
i'm going to get out of the way00:24:26
anyway here it comes00:24:30
three00:24:31
two00:24:32
one00:24:34
oh that was a big nothing00:24:36
ah you're kidding i was hoping for a lot00:24:39
more than that00:24:47
oh but you you can see how this thing is00:24:49
blown out and you can see it's bright00:24:51
it's it's uh basically broken the um00:24:55
broken the uh what do you call it the00:24:57
the bridge00:24:59
um00:25:02
i thought i thought it'd be a lot more00:25:04
dramatic00:25:06
we didn't need this we could have00:25:08
could have just um00:25:10
just let it sit on the table00:25:12
which is probably a good idea00:25:14
because i don't want a heck of i don't00:25:16
want to have a lot of00:25:18
stuff ruined on the circuit board00:25:20
if uh if there was some kind of accident00:25:22
or something i guess i'd want to i'd00:25:24
want to be able to00:25:27
to identify what's gone right and wrong00:25:30
at least maybe on that board so00:25:32
this is kind of a cool idea00:25:35
but it's a lot less than what i was00:25:36
anticipating as far as power is00:25:39
concerned00:25:40
yep so anyway there you go00:25:42
and now ben is going to talk to you a00:25:44
little bit about00:25:47
pulling uh00:25:48
uh00:25:49
sorry lifting lifting magnets with or00:25:52
lifting weights with magnets00:25:54
anyway uh00:25:56
stay tuned for that00:25:58
all right so we've completed all of our00:26:00
magnet testing i'm going to walk you00:26:02
guys through how we did that real quick00:26:04
here and then we'll show you some00:26:05
results so what we have is a force gauge00:26:08
that we used we mocked up a00:26:12
a bolt on a wire so that we can pull00:26:14
this is what's going to stick to the00:26:15
magnet we're going to pull this off of00:26:16
the magnet00:26:18
we took a another large piece of steel00:26:21
that we have which is our forklift tine00:26:23
we marked an area here we put the magnet00:26:26
on it so we can use the same piece of00:26:28
the forklift each time00:26:31
and all we did was take the00:26:33
the bolt00:26:35
connect it to the magnet00:26:38
and then we turned on our00:26:40
our gauge we used our peak peak value00:26:48
put it in the loop and we pulled it00:26:51
off00:26:54
so this would have came out at 14000:26:56
newtons of force00:26:59
so we did this 10 times for each of the00:27:01
magnets we used the bmw i3 we chose one00:27:05
because that was the first00:27:07
electric vehicle the motor that we have00:27:08
in-house so it's the oldest one that we00:27:10
have we used a tesla model y00:27:13
we also did the00:27:14
mach e rear motor as well as the model s00:27:18
and as you can see the model s00:27:20
does have the strongest force to pull00:27:22
this00:27:23
this bolt off of the magnet00:27:25
and that's just what we mean by this is00:27:27
a strong magnet it's just a very00:27:29
anecdotal test00:27:31
as we get anecdotal feelings we do send00:27:33
all of these magnets out to get their00:27:35
goss ratings and that is available in00:27:37
our motor reports00:27:38
and that's more what kind of number you00:27:40
would use if you're designing a magnet00:27:42
designing a motor00:27:44
okay well that's our little motor00:27:46
demonstration here thanks for watching00:27:49
um stay tuned for corey's announcement00:27:52
on how much those laminates are go for00:27:55
and uh stay tuned we're gonna show you00:27:58
quite a bit more this this car is full00:28:00
of surprises thanks for watching again00:28:02
bye now00:28:27
