Induction Motor

Torque Equation of Induction Motor

The torque T, of an induction motor, is proportional to the product of stator flux per pole ( φ ), rotor current ( I ), and the power factor of the rotor. The torque of an induction motor is due to the interaction of the…

Cross-field Theory of Single phase Induction Motor

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 fiel…

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 wi…

Losses in Induction motor

The losses in an induction motor can be 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. The…

Types of Single Phase Induction Motors

Types of Single Phase Induction Motors :      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, manual…
