Abstract:
In today’s industrial world three phase AC induction motor is considered to be the
leading horse of the industry, many applications require variable speed and torque
implementation. Applications that are driven by three phase AC induction motor and
do not require full speed, by controlling its speed through variable frequency drive a
considerable amount of energy can be saved. We have designed speed control system
which controls the speed of motor through controlling the frequency of electric power
supplied to the motor. Variable speed control system is designed and implemented
through VF control method. Graphical user interface (GUI) is designed using
LABVIEW.
