Heat capacity increasing design of rare earth IPMSM for temperature rising suppression

摘要

In this paper, the temperature rising of the IPM type motor was inhibited by increasing the heat capacity according to the increase the frame length. Thermocouples were attached on the teeth and coil end turns of IPMSM, and temperature rise experiments of the basic model and the increased model of heat capacity were performed. Validity of this study was proven through the comparison of the experimented results with the simulation ones.
