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 price. Like DC motors, they are permanent-magnet synchronous motors, or PMSMs, that trust magnets included in the rotor.

In a brushed DC electric motor, the rotor spins 180-degrees when a power current is run to the armature. … In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A Brushless Ac Motor china computer then charges the electromagnets in the stator to rotate the rotor a full 360-degrees.
