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 price. Like DC motors, these are permanent-magnet synchronous motors, or PMSMs, that rely upon magnets included in the rotor.

In a brushed DC 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 computer then costs the electromagnets in the stator to rotate the rotor a complete Brushless Ac Motor china 360-degrees.
