AC Brushless Motors. AC brushless motors 
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 electric motor, the rotor spins 180-degrees when a power current is run to the armature. … In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then costs the electromagnets in the stator to Brushless Ac Motor china rotate the rotor a full 360-degrees.
