Stator : It is the stationary part of the machine and is built up of sheet-steel laminations having slots on its inner periphery. A 3-phase winding is placed in these slots. The

WebWhenever the magnetic structure of a Cylindrical Rotor Synchronous Machine is subjected to rotating mmf vector, it is seen as an mmf phasor from the stator with its flux phasor in phase with it, while the phasor representing the phase emf induced lags behind both these phasors by 90° (see Fig. 8.3). It was shown in already that when a 3-phase ... WebJan 11, 2024 · The motors start as induction motors. When they approach synchronous speed, the slots enable the synchronous magnetic field to lock onto the rotor. The motor then turns at synchronous speed so long as the required torque is low. In the reluctance motor, the rotor has projecting poles that resemble individual teeth.

WebSynchronous machines are AC machines that have a field circuit supplied by an external DC source.
