AC Brushless Motors. AC brushless Brushless Ac Motor Motors use the induction of a rotating magnetic field in the stator to turn the rotor and stator at the same rate. Like DC motors, they are permanent-magnet synchronous motors, or PMSMs, that trust magnets included in the rotor.
In a brushed DC motor, the rotor spins 180-degrees when an electric current is set you back the armature. ... In brushless DC motors, the long 
lasting magnets are on the rotor, and the electromagnets are on the stator. A computer then costs the electromagnets in the stator to rotate the rotor a full 360-degrees.
