AC 
Brushless Ac Motor china brushless Motors. AC brushless motors utilize the induction of a rotating magnetic field in the stator to carefully turn the rotor and stator at the same rate. Like DC motors, they are permanent-magnet synchronous motors, or PMSMs, that rely upon magnets built into the rotor.
In a brushed DC motor, the rotor spins 180-degrees when a power 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 costs the electromagnets in the stator to rotate the rotor a full 360-degrees.
