When an induction motor is lighty loaded, the efficiency can be very Substantially improved by controlling the constant slip frequency. The in the system which requires constant speed under either normal load or light load, it is possible to save energy by means of controlling the constant slip frequency,
In this paper, the required relationships between optimal efficiency and constand slip frequency control is derived and the simplified control a1gorithm is suggested .
