In 1891 at the Frankfurt exhibition Nikola Tesla presented a crude type of induction motor of poly phase. Induction motors are widely used. Almost 80% of the world's a.c engines are poly phase induction motors. So the speed control of this engine is an important agenda. The speed control of the poly phase induction motor can be done through different methods. Here we will discuss the speed control of the winding rotor induction motor using the variation of the rotor resistance. The conventional method for varying the rotor resistance was made by inserting a variable rheostat in series with the 3-phase winding of the motor. This method of speed control faced problems and this was not economically viable. Variation of rotor resistance can be made using electronic power devices and this is a more efficient method. Here we are going to show how this can be achieved.
The speed control of the 3-phase induction motor depends on several factors such as the voltage supplied, the frequency, the number of poles. The speed of the 3-phase induction motor must be varied according to the requirement. The speed controls from the stator side as well as the rotor side are also.
Induction motor is practically a constant speed motor, ie for low load conditions, the change in engine speed is quite small. The reduction of the speed of the induction motors is accompanied by a loss of efficiency and a power factor deficient. As induction motors are widely used, their speed control may be necessary in many applications.
