The speed of an induction motor can be controlled by two major methods. They are: Stator side control Rotor side control The first method is applicable for both squirrel-cage and wound-rotor motors. The second method can be used only for wound-rotor motors. Stator side control means, we have to vary the stator side parameters, supply

When 3- Φ Induction motor is switched on at normal supply voltage, heavy current “ill flow through the motor because at the time of starting, there is no back emf. An induction motor, when directly switched on, takes five to seven times its full load current and it develops only 1.5 to 2.5 times full load
