Tesla's Newest Motor & Drive Unit
Рет қаралды 156,856
Жыл бұрынHere we teardown Tesla's newest Motor and Inverter tech!
The Tesla part number for this Drive unit is 1665000, so I'm calling it the "Triple 0". Tesla also has a 3 letter designation of 4D1.
Weight (wet): 194 lbs/88 kg

I used to be engineer with a company that produced fork truck DC controllers (largest I had worked on was a 60V 900A) and later mobile wheelchair and scooter controllers. Super impressed with how compact and simple this design is! I know to make things simpler and cheaper its a lot of work (same goes for software - more effort to reduce code complexity).

This inverter can handle that current at 400 volts, and is way more efficient than any 60v inverter could be.

@@Ingineerix For sure - high voltage for less resistance losses. When I started we had to use bipolar power transistors which under full load might have a saturation voltage of 0.5V or more - and very high switching losses too. The transistors were screwed down to big blocks of aluminium which in turn were bolted to the vehicles chassis for further heat dissipation. Because of the switching losses most controllers PWMed at sonic frequencies (except some that use speed up transformers to achieve 20 kHz). When the metal transistors blew up it was quite spectacular (where I used to test controllers had marks on the walls for many years)! MOSFETs (and subsequent variants) were a revolution. Even so the Tesla engineering is top notch for sure.

What (still) impresses me is that this basic motor concept drives all vehicles from Model 3 to the Semi (we can no doubt add the new models as they arrive) It's essentially just a question of changing the gearing (and decoupling on the Semi ... Maybe the CT🤔?), then altering the power application map to suit the vehicle. "Genius".

For the hairpins, do they use a form of Litz wire in bar format? Similar to Lucid's laminated hairpin but hopefully better (matrix rather than stack and if we're lucky woven to reduce hot spots). Obviously insulated threads and compressed down to a "bar" to create the hairpin...

The problem with open inverter on a hybrid PMSRM like this, is that Tesla has probably tens of thousands of hours development into the inverter firmware, which is why this is one of the most efficient and power-dense motors produced. If you just toss that and roll your own with on;y a few hundred hours (if that) of development is you lose a lot. I prefer to drive the motors keeping the Tesla firmware intact.

Same motor/inverter on both 3/Y, but they do allow higher power output. The Model Y is heavier, so they bumped the power a bit to allow it to try to keep up with the Model 3 a bit better. Yes, there is a lot of power "on the table" in this design, they essentially use the same parts in the Plaid. There are a lot of reasons to limit power, we have to consider the battery pack, powertrain longevity, chassis traction limits, and finally marketing. They don't want a performance Model 3 showing up their expensive flagship Model S.

A 400V DC shock is approximately like 800VAC, it's super dangerous. The arcing potential is high, and the amount of amps the battery can supply is terrifying. Tesla's got a lot of safety systems designed to keep the HV away from people, but if you "tap", then you are bypassing this. I'm happy to discuss over email if you like, but I can't condone anyone without proper qualifications attempting such a thing. General electrical knowledge is just not enough, and if you are qualified then you'd already know how to do this, and do it safely. I did it in 2015, and it's not a problem, but non-trivial.

How can other OEMs possibly compete with Tesla's pace of innovation
@Ingineerix Жыл бұрын
So far they can't. Tesla now has a good heat start that they seem to be keeping. They also have significant cost reduction now through economies of scale and relentless optimization. It will be hard for anyone else to sell an EV for what Tesla is and still make money.

No, the inverter isn't considered "serviceable", you would just replace it as a unit. Luckily Tesla builds extremely reliable electronics.

I can already see Sandy trying to pick his jaw off the floor. The cost down on this vs. last rev is a work of art I'd say they dropped 13-18% just in material cost. 35-40% from the hairpin, another 8-12% on the driver. I can easily see this with an induction rotor in a 25k car with a 65kwhr battery I bet they shaved 15-20kg off the unit weight and that's says a lot given how Good the last one was compared to the rest of the ev market

@carholic1336 I have a cybertruck pre-order in the first 500. So, of course, I agree. But the inverter + hairpin stater + an induction rotor in volume here is under $ 1500 usd with tesla's currently around 85-90$ per kwhr, so a apx 6000$ usd for the battery. So expect all the running gear to be under 10k$ then just the body costs, and with the die-casting, the costs have dropped dramatically. So yes, tesla taking advantage of all its current IP, a 25k car will be easy

Can you comment on the magnets and any rare earth usage?
@Ingineerix Жыл бұрын
I don't have any way to analyze the composition of the magnets, but they seem strong enough to have some rare-earths still. Overall compared to other EV motors, the magnets are not that big though. (This motor is a Hybrid Switched-Reluctance that doesn't depend on the magnets as much)
@olyalphy Жыл бұрын
@@Ingineerix No worries, thanks for the reply! Yeah, would require some special equipment or tools to analyze. Recommend you checkout "Two bit da vinci" on his recent video on the next gen motor. Seems it is possible to get strong magnets with this new approach. We just don't know how/when/where Tesla are using 0 rare earths in their motors.

Last year I visited a company in germany which builds the machines which manufacture those hairpin Stators. Its really fascinating to see those machines first bend and cut the individual hairpins and then assemble the complete stator. That company said they supplied Tesla with such machines, so i guess those are the fruits of that labor.

They have not changed the architecture of the PCS (charger), and in fact it's now migrated from the Model 3/Y to the S and X. Tesla wants you to buy a powerwall, they don't want to take business away from that cash cow.

@@Ingineerix I keep hoping. The power offtake from the car wouldn’t be a replacement for Powerwalls, it’s use case would be for powering things like power tools, or job sites, and for emergency backup power, but not for daily use like a powerwall. During investor day, I think it was Elon who said that all Tesla vehicles will have power offtake within a couple of years after remarking how Cybertruck will have it.

Tesla considers both the lubricant (ATF9) and the filter to be lifetime. I advise people to change the ATF9 every 40k; cheap insurance. No need to change the filter because it will never really have much contamination. It's not like an ICE with blow-by combustion products and high-temperatures contaminating the oil.
