This paper presents a technique to control the speed of single phase induction motor by using TRIAC and reversal of direction of motor. A single phase induction motor except that its stator is provided with a single phase winding. The rotor of any single phase induction motor is interchangeable with that of a poly phase induction motor. A single phase winding produce no rotating magnetic field and no starting torque. The speed of Induction motor can be varied in a narrow range by varying the voltage applied to the stator winding. This method is suitable for such application where the load varies approximately as square of speed, such as centrifugal pumps drives, fan load, refrigerator, blower etc.
