- High output induction motors working in polish industry are the subject of the paper. It is estimated, that only in polish powerplants work more than 2000 motors output higher than 200 kW. Also in brown coal-mines hundreds of high voltage slip-ring motors are installed. The presently exploited motors are mainly out-dated, manufactured and designed more than 20 - 30 years ago. These motors are characterised by low efficiency factor and high noise level. Figure 1 indicates the value of efficiency factor of different type induction squirrel cage motors (domestic and foreign). It can be easily noticed that modern motors have the efficiency factor higher of even 4% than the old ones. The old motors should be replaced by modern, energy efficient ones. The Table 3 and 4 present the possibilities of replacing these old machines by new, modern motors. In case of replacing motors in powerplants with generation units of 200 MW, savings of electricity per 1 drive and for all main drives together are shown. The total energy power savings balance at the level of 500 kW, what for 7000 operating hours per year enables to save about 3400 MWh.
