WebThe stator of an induction motor consists of a number of overlapping windings offset by an electrical angle of 120°. When the primary winding or stator is connected to a three-phase alternating current supply, it establishes a rotating magnetic field which rotates at a synchronous speed. The waveform of the three fluxes is as given below. WebQuestion.

WebMar 6, 2015 · Rotating Field Generator From the word itself that means that the field coil that produced magnet (magnetic field) is located in the rotor and being moved by a prime mover action. This is completely opposite to the rotating field type of a generator but this is the most common type of AC generator used in the industry. WebSpeed is important to the rotating magnetic field of an AC motor. It is known as “ synchronous speed .”. This speed is calculated by dividing 120 times the frequency (F) by the number of poles (P). As an example, the synchronous speed for a 2-pole motor operated at 60 Hz is 3,600 RPM. As the number of poles increase, synchronous speed ...
