AC Brushless Motors. 
AC brushless motors utilize the induction of a rotating Brushless Ac Motor 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 included in the rotor.
In a brushed DC engine, the rotor spins 180-degrees when an electric current is set you back the armature. … In brushless DC motors, the long term 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 complete 360-degrees.
