AC Induction Motor Control Using the constant V/f Principle and a Natural PWM Algorithm (12 pages, revision A, updated 12/05) Induction motors can only run at their rated speed when they are connected to the main power supply. This is the reason why variable frequency drives are needed to vary the rotor speed of an induction motor.
