AC Brushless Motors. AC brushless 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 rely upon magnets included in the rotor.
In a brushed DC electric motor, the rotor spins 180-degrees when a power current is set you back the Brushless Ac Motor china armature. … 
In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then charges the electromagnets in the stator to rotate the rotor a complete 360-degrees.
