It is interesting to know how a single-phase induction motor can able to rotate when an initial rotation or starting torque is given to it. This can understand with the help of cross-field theory and double-revolving field theory…
When a single-phase ac supply is given to the single-phase stator winding, a sinusoidally pulsating magnetic field varying with time is produced. As the produced magnetic very two times in a cycle, therefore, no torque will be pr…
The losses in an induction motor are classified as, Constant losses, and Variable losses. Constant Losses : Constant losses are those which doesn't affect due to variation in load conditions on the motor. These losses rema…
Single-phase induction motors are not self-starting because there is no rotating magnetic field produced. It is not practicable to provide initial rotation to the rotor, manually. So in practice, some provision is made to provide…
