Synchronous induction motor operation
WebOne feature of the synchronous machine is that it has two electrical sources, one for the rotor and one for the stator. Intuitively, it makes sense that as more power is required by the mechanical load on the motor, one or both of the magnetic fields must get stronger. Essentially, either winding can provide exciting current for the machine ... WebAug 10, 2024 · The gross motor efficiency h m (neglecting stator and mechanical losses) is: h m = P m / P t = 1 – s.
