Induction motor for many years has been regarded as the workhorse in industrial applications. An induction motor can run only at its rated speed when it is connected directly to the main supply. However many application need variable speed operations. With the invention of Variable Voltage Variable Frequency drives (VVVF), the use of an induction motor has increased. Variable voltage variable frequency control provides a simple and cost efficient method for open-loop speed control of three phase induction motor.
