AC Brushless Motors. AC brushless motors use the induction of a rotating magnetic field in the Brushless Ac Motor china 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 motor, the rotor spins 180-degrees when an electric current is set you back the armature. … In brushless DC motors, the permanent 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 complete 360-degrees.
