Abstract :
This paper describes a loss analysis of an eddy current generated in the copper-bar windings of a 1.5-kW, 150,000-r/min PM motor fed by a 12-V power supply, which is applicable to an automotive supercharger. The proximity effect in the winding conductors is a result of the eddy-current caused by the magnetic fields generated by the neighboring conductors. The analysis results show that the proximity losses can be significantly reduced by an appropriate magnetic shielding and segmentation of the conductors.
