05.10.2019Working of a Single-phase Induction Machine. When a three-phase power supply is given to the stator winding of the machine, RMF will be developed. The RMF interacts with the short-circuited rotor conductors. Due to this, an emf is induced in the rotor bars according to the principle of mutual induction just like a transformer. But the rotor

When the motor is connected to a single-phase power supply, the main winding carries an alternating current. This current produces a pulsating magnetic field. Due to induction, the rotor is energized. As the main magnetic field is pulsating, the torque necessary for the motor rotation is not generated. This will cause the rotor to vibrate, but not to rotate. Hence, the single-phase
