Thank you! I drive a 2019 Toyota Prius Prime, and this video is the best explanation I've ever found on how the cars two motor/generators work. One thing the video didn't mention: there is a sensor on the rotor shaft of each of the Prius's motors, that continually and very precisely tracks the angle of the rotor around it's 360° circle. The signal from this sensor is fed to the motor control computer, which is controlling the bank of high-power MOSFET transistors in the inverter, that create the 3-phase alternating current that power the motor stator windings. As the video explains, there is an ideal phase-angle relationship between the magnetic fields in the rotor's permanent magnets, and the phase angle of the rotating magnetic fields being produced by the stator. The motor control computer continually adjusts and optimizes this phase angle, based on the signal from the rotor position sensor, and other sensors, plus the driver's demand for power given via the throttle pedal or cruise control setting. I assume that the Tesla, and other EV cars, have a similar sensor on the rotor.

That's what they are demonstrating at 5:30 and 6:45 by placing permanent magnets within the slots in the rotor. Not saying this is cake work to design and build, only that the concept is simple to understand once you know the language.

Great style of explanation

Many thanks for the explanation! Regards from an electrical engineer

One of the reasons they used induction motors in the first place is the criticality of dysprosium, a rare earth element in which China controls 90% of which is used in high performance permanent magnets. Luckily, this is changing as the US is opening a mining facility in Mountain Pass and Australia is also starting to produce.

Great to see strides made to reduce back EMF in new motor designs. I just hope they keep the moving parts at a minimum and don't go the "VVTI" route and start adding complexity and internal moving parts to it to "maximize efficiency by moving the magnets closer to the outer edge on startup and/or changing the angle relative to the reluctor slots on the fly to vary the torque". The newer internal combustion engines are getting ridiculous in that regard, increasing complexity and therefore cost while decreasing reliability, repairability and longevity. All this done to say they are whatever percent more "efficient". To me efficiency means to do more with less. K.I.S.S. BTW, is that a passive heat pipe built-in the motor shaft at 11:40 ? Wouldn't the spinning shaft affect the flow or is that a simplified representation with the actual part having spiral grooves cut into it like a rifle barrel to aid fluid movement?

They wont having 96% eff is insane only Aliens have invented 100% unity

讲解的非常好，工程师辛苦了！

I AM so glad that I found this KZread channel

This " new " motor is the same I have in my skateboard, BLDC. It's been fine for years. All motors produce some back EMF and that's what's used for regeneration braking. But anyway I want one .

We are at the dawn of advanced motor engineering - with the amount of money pouring into EVs and the competition for carmakers to survive, EV motor technology has the potential to really accelerate over the next decade or two.

Electric motors already are at the higher end of 9X% efficiency, which is already double the efficiency of combustion engines. It's cool if they get another %, but if you want EVs to get a jump in performance, the batteries, like QuantumScapes new Solid State Battery design, have the most potential.

@@carstekoch The competition for motor improvement doesn't stop at efficiency. Gains in motor power and rpm's will remain ongoing.

@@stevenhill3136 Yes and no. If you desperately want a Single gear EV, maybe with 4 motors one on each wheel, than this is a valid concern, otherwise you can just insert a gearbox and regulate your power and rpms through that. at the cost of weight and maybe space.

What a incredible presentation

Amazing breakdown! Wish you were my professor in the uni...

The rotor's magnet catches the magnetic field lines as the stator windings rotate laterally.

I am not a mechanical student but i got an pretty good idea how an EV motor works after watching this ....Good job!!!

It's electrical engineering bruh!!! Nothing to do with mechanical! Mechanical engineers don't even know the basics of electrical!! Wtf.

Nice explanation with the help of impressive animation.

Thanks for sharing these information 😊
