The 5kW hub motor in my motorcycle is PMAC/BLDC. It's fed three-phase AC thru an inverter. Not that I would ever do such a thing, but if someone were to take it apart, they might see this:Smidge204 wrote:Electronically commutated motors, rather than brushes. The most common type I'm familiar with is PC fans; the rotor is a permanent magnet and the stator is on the inside. A hall effect sensor senses the polarity of the rotor magnets as it rotates and some transistors switch the current in the stator windings.Herm wrote:Andy refresh my memory, an example of a brushless DC motor?
Though I've never seen a high HP one I'm sure it's possible and I wouldn't be totally surprised if they exist in multi-HP sizes. I'm skeptical they make them "car sized" though... at that point the power electronics and controls are such you might as well go with an AC motor.
Here's a 3000Hp version:
Here's where one may find it:
