AC Brushless Motors. AC brushless motors Brushless Ac Motor utilize the induction of a rotating magnetic field in the stator to turn the rotor and stator at the same rate. Like DC motors, these are permanent-magnet synchronous motors, or PMSMs, that trust magnets built into 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 permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then fees the electromagnets in the stator to rotate the rotor a full 360-degrees.
