Tesla Model 3's motor - The Brilliant Engineering behind it

Youtube has recommended a few videos from the channel Learn Engineering that have been surprisingly good. For example: [VIDEO]

A tesla Model 3 motor already is partially a reluctance motor. This youtube video describes it rather well, and I'd recommend giving it a watch [1]. Notice the air gaps - thats the reluctance part of the rotor. [1]: [VIDEO]

> The engineers of Tesla motor's shocked everyone when they abandoned the versatile induction motor in Model 3 cars. They used a totally different motor called IPM-SynRM. Let's understand why the Tesla engineers made this crucial design change. [VIDEO]

"Instead of using air gaps, Sansone thought he could incorporate another magnetic field into a motor."

> What sort of motor do you think a Tesla model 3 uses, for example? IPM-SynRM [VIDEO] They went into a lot of effort to optimize it over RPM range. If you want to make a point use real motor curves at least. Your graph suggests it goes to sub 20% efficiencies at low speed which is completely false and would suggests way higher gains from gearbox than in reality. Hell, it would suggest ICE like performance, it's THAT bad.
