AC Brushless Motors. AC brushless Brushless Ac Motor china motors utilize the induction of a rotating 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 rely upon magnets built into 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 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.
