Induction Motor

Phasor Diagram of Induction Motor

The induction motor and transformer both are singly energized devices. The stator and rotor of an induction motor can be compared to the primary and secondary windings of the transformer. Similarly, from the e.m.f. equation…

Maximum Torque Condition of Induction Motor & Expression

In the last article, we have seen the torque equation of induction motor i.e., the amount of torque produced on the rotor depends upon rotor current, rotor resistance, rotor reactance, and slip.      From the torque-slip c…

Torque Slip Characteristics of Induction Motor

We know that the induction motor is an asynchronous motor ( i.e., not a constant speed motor ). Its speed changes with a change in the load connected to it. As the load on the motor increases the slip of the motor increases…

Equivalent circuit of an Induction Motor

Induction motor is an asynchronous motor i.e., its speed change with a change in load. It always runs on a lagging power factor. The principle of working of an induction motor to similar to the transformer i.e., on electrom…
