- In designing the high-speed low-power induction motors should be pursued to obtain operating characteristics similar to characteristics of general purpose motors and the greatest efficiency at rated load. One way to increase the efficiency of induction motors, particularly those working at higher frequencies, is applied to the motor core electrical sheets with improved magnetic properties and less core losses, including amorphous iron. The paper presents a comparison of measured operating characteristics of several low-power induction motors, a core made from three types of electrical steel, working with supply from the inverter voltage with a frequency varying in a wide range (from 0 to 200 Hz), and grid-supplied frequency 50 Hz and 100 Hz. In the case of grid-supplied motors paper presents the results of calculations made using the available methods from the literature, with particular emphasis on determining the additional losses in both the no-load and at rated load. The calculations used, experimentally determined for the tested motors, the mechanical loss characteristics, and also measured the magnetization characteristics for electrical sheets and sheet specific losses as a function of magnetic flux density for a wide range of frequencies.
