Construction Details of Synchronous Motor

As there is no constructional difference between dc generator and dc motor, similarly, there is no difference between the construction of a synchronous motor and synchronous generator ( alternator ).      The constructio…

Efficiency and Power Flow Diagram of Induction Motor

Power Transfer Stages of Induction Motor :      Induction motor converts an electrical power supplied to it into mechanical power. The various stages in this conversion is called as power transfer stages in an induct…

Induction Motor Applications

Most of the motors used for household and commercial purposes are induction motors. The use of an induction motor as induction generators is insignificant. An induction motor has nearly constant speed motor characteristic…

No Load Test of Induction Motor

This test is similar to the no-load test performed on a transformer. The purpose of this test is to determine the no-load losses , no-load power factor, and constants  R o  and  X o  of the equivalent circuit.      The no…

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…
