Induction motor vector control for washing machine

For technical and economic reasons, the drum drive system employed in the domestic waking machines have traditionally been based on a combination of a high speed induction motor and a pulley and belt. This paper deals with washing machine drive based on an inverter fed induction motor. In this case, voltage is applied in proportion to frequency to achieve rated torque though the range. But scalar control such as V/f methode is somewhat simple to implement, but the inherent coupling effect given sluggish response. Therefore, this paper describes study on induction motor vector control for drum type washing machine.
