Also even though he worked with some USA OEMs he doesn't shy from talking about their weaknesses. He and his staff have a very objective opinion about EV tech which is refreshing.

Thanks Sandy for this motor teardown. I can comment on the winding technology wound vs hairpin. I work with engineers to help them simulate and design these different types of windings and they both come with pros and cons. Wound windings are well known and more flexible in their design, you can make them fill a slot of any shape with a rather good fill factor. The insulation between each separate wire makes that fill factor impossible to reach 80% for instance. Designers usually can go up to 50-60% of copper in the slot. In terms of layout it is also easier to do any sort of connection as you can bend and reposition wires "easily". The cooling of these wires is not very easy as it comes as a large bundle of wire with resin/impregnation around them. Hairpin windings are a recent trend as they provide some benefits. The fill factor can be a bit higher but the slot has to be rectangular. Also as you mentioned Sandy, with higher speeds, you have higher frequency currents and then you can start to have eddy currents and proximity effects going on. It means the current goes mostly on the outside of the section, so you increase your AC losses. Also the conductor closer to the rotor and the airgap sees more varying magnetic flux density which also generate more losses as well as unbalances between wires. The connection of several paths of hairpins also creates unbalances in genral and you can have circulating currents. So in general, it looks easier on paper, or to manufacture and assemble but it means more challenges and less flexibility in the design. I think Tesla kept the wound windings for the simplicity it brings even if it may mean a slightly lower fill factor. They chose initially induction motors over PM motors for the same reason. Regarding the V shape or W shape of the magnets, it is obviously a very sensitive design depending on the performance to achieve, the magnets help for the low speed torque and the V shape acts to create reluctance torque at higher speeds. A tiny change in angle or dimension can change the torque or performance by 10% and the cost of magnet material as well. I work with Altair and we can test and simulate those several multiphysics effects. More than happy to answer any questions.

I don't work in the field, but I thought the difference in layout of the magnets might be due to the different diameters. Magnets that are placed closer to center would need to have a different angle to align to the magnetic field lines than magnets that are placed further out from the center.

In the term "induction motor", the "induction" refers to current induced in rotor conductors (windings or cage) by changing stator magnetic fields, producing a rotor magnetic field for reaction. That is not how this motor works; there are no conductors in the rotor and the motor does not work by inducing rotor current.

The industrial motors you might be thinking about are rated for 24x7 operation at 100%, sometimes even more. Also they require no "external parts", ie water cooling system to work. Electric motors in EVs can deliver a huge peak power, but they are not rated to work at 100% all the time. If you see any EV accelerating, it will reach max speed (legal or driver desired), in a few seconds, maybe hitting 100% power output. Once the car is at constant speed, it will consume an smaller amount. An EV at 100~120 km/h consumes about 20~30kW even on a climb, way less than peak power. The EV motors can operate continuously at this "low" power numbers with liquid cooling without issues.

Some nice praise for Ford from Sandy and Co. Ford should be very happy about this overview. Interesting stuff Sandy!

Nice IGBT modules. The integrated water cooling fins and contacts are well thought out. The DC input buss bar is also extremely well done. Keeping the positive and negative plate close and parallel minimizes input inductance and RF noise. You can see this pay off because the don't need a DC input filter inductor and capacitor to keep RF noise inside the inverter. Would not be surprised if the power input pins to the IGBT modules alternated + - + - + to minimize inductance as well. Like the intermediate gear in the gearbox too. Adding the long shaft between the large input gear and small output gear provides enough space to fit a standard gear Hob tool. Is the differential a spur-gear planetary design? They have a few more parts than a bevel gear design, but can be extra compact.

What I want to know is did Ford have anything to do with the design of this motor or was it all Magna, and Ford just basically bought this off the shelf. I have a 2017 Ford focus electric, and I believe the powertrain in it was completely designed by Magna.

Magna is a Tier 1 supplier - that means it supplies parts directly to the assembly line in a just-in-time fashion. Ford, GM, and Chrysler got rid of alot of their in-house people and went to suppliers. That's why Magna became such a huge company - it took on the work that the "big 3" in NA were outsourcing. Magna also builds entire vehicles. They are building the Fisker vehicle. They recently entered into a Joint Venture with LG to produce electric drivetrains, inverters, and other systems. The traditional automakers going forward will very much depend on suppliers like Magna for electric systems. That's not a bad thing, Magna employs 169,000 people worldwide and they in turn have their suppliers for stuff, also worldwide. Besides, with Magna building so many different parts for so many different vehicles, they are in a position to draw on their experience on what works best, where. We shouldn't be surprised at seeing some innovative designs from a supplier like Magna.

Sandy call out poor deign and implementation for what it is. If that’s rude then perhaps it’s what’s need to get the providers to improve their product. I have never seen him aggressive or rude to people. He’s direct but he’s not disrespectful.

Love that new info changes Sandy’s perspective, does a lot for credibility other than unbiased critique.

I noticed Ford had tapered roller bearings on the differential / final drive. Much more robust than ball bearings.

I wonder why Ford didn't go with Magna in both front and rear motors? The rear motor is Borg Wagner, which didn't look as nice as the Magna version.

As Sandy mentioned in previous videos: 2 engineers not communicating to each other. Or Ford just took what they had in the parts bin.

The front and rear have two different sets of requirements (for power, space, weight, etc), which were met by two different product, which happened to come from two different suppliers.

It's almost like the two inverters were made by totally different companies

Once again, great dissection Dr. Munro! So wouldn’t an oil filter in a lubrication system increase the longevity of the device? I imagine Tesla having more electric vehicles on the road than anyone else might have a evaluated this, no?

A gearbox in an EV is similar to a rear diff in an ICE car. They don't have pumps or filters and they last the life of the car. It seems to me Ford has more experience making transmissions than Tesla.

Some guy in Germany has a 10 year old Tesla with over 1 million miles driven. His motor seems to work fine.

I’m 62. Is it to late to change my major to engineering?

Great analysis!

So happy to see other companies improving and getting thins done right. Except for the cooling and some extra weight, the Mach-e seems to be a really good vehicle.

6:20 gasket vs rtv? Which is more likely to leak after years of service? I’ve had rtv that just stays glued like no tomorrow and would be a better choice for long term service and no issues.

Nice intro man

Outstanding. Thnx.
