Permanent-magnet brushless DC motor within the rotor

The stator is driven by electronic switches (which replace the Carbon brushes), controlled by a microcontroller.

Electronic system (hall effect sensor or software is used to recognize the rotor position)

AC operated (230Volts Single phase or 380/480Volts 3phase, 50/60Hz)
