Abstract
Electrical drives are universal sources of mechanical energy covering a wide range of power, speed and torque, from miniature motors in watches (10−6 W) and cameras to high speed compressor drives, large ore mills or pumped hydro storage plants (108 W). It is estimated that half the electrical energy produced in an industrial country is supplied to drives for reconversion to mechanical forms of energy. While most of these drives are of the constant speed type, where the losses of the motor determine the overall conversion efficiency, the application of adjustable speed drives is also rapidly increasing. They offer a large potential for energy conservation and are able to meet the needs of any load.
