AC Brushless Motors. AC brushless motors use 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 Brushless Ac Motor china electric motor, the rotor spins 180-degrees when a power current is run to the armature. … In brushless DC motors, the long lasting 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.
