A switched reluctance bearingless motor (SRBM) with single layer windings is presented. Particular effects of eddy currents on iron losses, torque and radial forces are analysed. A new principle to explain distribution of magnetic flux in motor sheet caused by eddy currents of frequencies from 3 000 Hz to 90 000 Hz is introduced. Iron losses, torque and radial forces are new estimated and calculated considering effects of eddy currents. The paper provides an overview of interdisciplinary research for eddy current effects on high-speed motors. Some valuable conclusion can be achieved from the results to better design a bearingless motor, especially its cooling system.
