Abstract :
Low-speed multiple-pole permanent-magnet (PM) synchronous machines have been widely used in direct-drive (DD) applications. Influences of pole number variation on various aspects of machine performance, including power density, power factor, and magnet-demagnetization, are analyzed in the paper. A pole number selection strategy is proposed based on overall considerations of machine cost and performance. A series of FE models are built to illustrate the analysis and strategy.
