AC Brushless Motors. AC brushless motors utilize the Brushless Ac Motor china induction of a rotating magnetic field in the stator to carefully 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 engine, 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 charges the electromagnets in the stator to rotate the rotor a full 360-degrees.
