The motor itself is ridiculously simple: it’s essentially a brushless DC motor with a unique winding ... and vice-versa. The rotor is a ring with permanent magnets, all arranged so that they ...

The rotor is the rotating element of an electric ... an external motor controller to modulate DC current (brushless DC motors) and ones that use AC current (permanent-magnet synchronous motors).

[Levi] whipped up his brushless DC motor design in OnShape. The motor has six coils in the stator, with the rotor carrying eight neodymium magnets. It’s an axial flux design, with the rotor’s ...
