Years with an HN recommendation, 2007–2026
HN recommends it as a clear explanation of the Model 3 motor and reluctance rotor design.
An engineering explainer on why Tesla abandoned the induction motor for the Model 3 and used an IPM-SynRM design. It covers the reluctance torque and permanent magnet principles behind the choice.
“This youtube video describes it rather well, and I'd recommend giving it a watch” (HN, 2022)
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]: [this 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. [this video]
Explains why Tesla chose IPM-SynRM motor in Model 3
> 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]: [this video] I dont think he's using air gaps? "Instead of using air gaps, Sansone thought he could incorporate another magnetic field into a motor."
Quoting parent's recommendation of the Model 3 motor video
> What sort of motor do you think a Tesla model 3 uses, for example? IPM-SynRM [this 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.
