Abstract

This paper looks at a systematic investigation on split ratio to minimize the AC losses of vertically placed rectangular conductors in concentrated-wound surface mounted PM synchronous machines having fault tolerant (FT) capability. The repeated numerical design optimization is carried out in Finite Element (FE) to achieve the required torque and FT capabilities for minimum level of electromagnetic losses. In addition, the influence of the tooth width to slot pitch ratio, slotting effects and tooth height are investigated. The proposed winding design is verified with FE analysis and validated experimentally. It will be shown that the overall losses can be minimised by adequate design.
