Permanent magnet motors. A permanent magnet synchronous motor (PMSM) uses permanent magnets embedded in the steel rotor to create a constant magnetic field. The stator carries windings connected to an AC supply to produce a rotating magnetic field. At synchronous speed the rotor poles lock to the rotating magnetic field.
of a geared traction machine and a synchronous PM gearless motor are the concepts of how the motor rota tions are generated. Asynchronous Motors A geared traction machine typically uses an asynchronous induction motor. The term induction refers to how the rotor magnetic field is gen erated. The sinusoidal AC current applied to a stator
