In the article two control characteristics U = f(P) for the loss minimizing in an induction squirrel-cage motor are analysed. These control characteristics are obtained from different methods. In the first method the voltage value is constant and the load value changes, Fig. 1. In the second method the load value is constant and the supplied voltage is variable, Fig. 2. The result of simulation shown that improving of the efficiency for given squirrel-cage induction motor is more effective by control characteristic of the second method, Fig.3 and Fig. 4. The differences between the efficiency improving of both control characteristics can be explained thought the creation 3-D efficiency diagram in function of the load and the supplied voltage, Fig.6. In addition “an ideal” induction motor for the variable load operation is discussed. This motor has possibility to minimize the total losses from no-load work to the rated load, Fig.5.

In the paper results of an optimal slip of the simulation research are shown. The optimal slip enables an induction motor to operate with minimum losses for given output power. The result of research is, that generally the optimal slip depends on load. When the load increases, the optimal slip is larger for every frequency. The modified equivalent circuit with resistances of stray-loss for simulation research is presented.
