- Nowadays the high-speed induction motors are widely used in many industrial installations and also in aircraft industry. Many of them are designed as converter-fed induction machines. Some electrical drives with not so sophisticated speed control have voltage shape with many higher harmonics. Examine the operation of high speed induction motors feed from PWM converters, with wide range of frequency, it is necessity for carefully considering of no-load losses of the motor. Results of formulas used in computer aided design for calculation of mechanical losses and core losses have shown good agreement with experimental data for motor feed from sinusoidal 50 Hz source but they have been not valid for higher frequencies. The main aim of the paper will be analysis of the no-load losses and no-load current for some small power induction motors feed with voltage of frequency from 50 to 250 Hz with different U-f ratio. For this problem circuit and field-circuit methods will be use and the results will be validating and computation methods will be improving basing on experimental results.
