Permanent magnet synchronous motor (PMSM)

The permanent magnet synchronous motor is cross between an induction motor and a brushless DC motor. Like a brushless DC motor, it has a permanent magnet rotor and windings on the stator. However, the stator structure with windings constructed to produce a sinusoidal flux density in the airgap of the machine resembles that of an induction motor Get price

Real Motor Speed

Synchronous motors produce a fixed magnetic field for the rotor, which allows them to rotate at the same speed as the stator's field. However, induction motors such as squirrel-cage or wound-rotor motors rotate slightly below synchronous speed, since they depend on electromagnetic induction between the stator and rotor. Get price
