4.9 A 6-pole, 3-phase alternator running at 1000 rpm supplies to an 8-pole, 3-phase induction motor which has a rotor current of frequency 2 Hz. The speed at which the motor operates is (b) 960 rpme (a) 1000 rpm (c) 750 rpm (d) 720 rpm

Q: The O smaller O larger the number of poles used in a stepper motor, the better the resolution

A: here we have to give relation between the number of poles and resolution.

A: In 3 phase induction motor supply is given to stator from stator power is induced in rotor through…

Q: List 3 differences between how 3 phase induction motors and single phase induction motors work

A: Induction motor is a widely used machine in the industry and for commercial purposes. based on the…

Synchronous Generator

In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.

Salient Pole Rotor

Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
