摘要：高速永磁无刷直流电机具有功率密度高、体积小、效率高等优点，在很多领域有着广泛的应用。对比分析了不同的转子充磁方式和转子支撑结构对气隙磁场、齿槽转矩和转子动力学的影响，优化设计了平行充磁和两端式支撑结构的23kW、150000r/min高速永磁无刷直流电机样机和控制系统，进行了试验论证，试验研究表明：两端式轴承支撑结构的转子成功运行到100,000r/min以上。

Abstract: High speed PM BLDC motors have been extensively developed and employed in industry applications, due to high efficiency and high power density. The influences of rotor magnetizations and rotor support structures on the airgap field, cogging torque and rotor dynamic of high speed brushless DC motor were comparatively studied. A rating of 23 kW, 150 kr/min high speed brushless DC motor and the control system were optimally designed. The experimental results show that two end support structure is successfully running up to 100krpm.
