induction motor control


The torque and speed of induction motors can be controlled by changing the supply frequency but keeping the voltage constant. If the frequency is decreased keeping voltage constant, then saturation of air-gap flux takes place. At low frequency, the reactance will decrease and the motor current may be too high.
