Abstract
This paper presents the methods in improving the efficiency using of magnet wedge. After the energy crises of 1970's, more emphasis was placed on higher efficiencies. Efficiency of an induction motor can be improved by reducing the total losses, copper, losses, iron or core losses etc. However high efficiency designs result, in larger size and cost than standard motors. In the methods of the reducing the losses, ripple losses of slot flux can be reduced by using the magnet wedge, but the starting torque decrease by means of increasing of leakage reactance.
