I'm really surprised that we haven't heard more about the Model 3's motor. Elon Musk sent a tweet a few months ago that mentioned the Model 3's motor is "switched reluctance, partial permanent magnet". From what I've been able to gather, this motor is almost an engineering unicorn that is almost all benefit with almost no drawbacks. The were able to overcome (previously) inherent limitations of switched reluctance motors through hyper advanced software control of the motor. Surely Sandy Monroe's company knows all about this motor's construction from their teardown. Perhaps they didn't realize what they were looking at or they are keeping quiet on it?
