Faults in Single Phase Induction Motors and their Remedies

During the operation of single-phase ac motors, it experiences various faults at the time of starting or stopping or while running. The faults in single-phase motors are due to many reasons like over or under currents, ove…

What is Crawling and Cogging of Induction Motor ?

Sometimes the induction motor shows undesirable characteristics known as 'Crawling and Cogging'. These characteristics will affect the motor operation i.e., it reduces the speed of the motor from its full speed rati…

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…
