This misconception that REE's are needed to build EV motors and that BLDC motors are better than ACIM's needs to come to an end. Just take a look at the power to weight of the Roadster motor. The FUDsters constantly rant about REE shortages meaning the end of the EV, not even close to the truth.

Yes - unless you need maximum hp/weight, there is no real need to use permanent magnet motors. In fact the Tesla uses an induction motor - something about them being able to handle higher current?

At 70lbs I'm not aware of a BLDC motor with a higher power to weight ratio than the Roadster motor.

No real need for a CVT with ACIMs, again look at the Roadster.
