【Abstract】 The general sizing equation is presented for designing a high power density brushless PM motor in this paper. According to the fact of big heat dissipation per surface area of the high power density motor, the stator frame is designed as a water-seal structure for circulating water-cooling. In order to decrease the volume, a new technology of winding connecting which effectively reduces the end length of the winding is applied. On the basis of Maxwell 2D Transient, the coupling simulation technology that incorporates the drive circuit into FEA is introduced to analyze the performance of the motor fed by power converter. And finally the experimental result of the prototype is showed in the paper. The experiment result proved that the motor achieves the requirement of the performance index.更多还原
