摘　　要：轴向分段式爪极电机具有转矩密度高、结构简单、制造成本低以及节约材料等优点。设计了一台1.5 kW、9000 r/min的轴向分段式爪极电机。对电机的电磁设计与温度分布进行分析,验证设计的合理性。对于爪极参数的选取,研究了爪极角与爪尖长度对电机转矩大小、转矩波动以及空载电动势的影响,给出了合适的选取范围。分析结果为新型真空干泵驱动电机产品开发提供了参考依据。The axial segmented claw pole motor has the advantages of high torque density,simple structure,low manufacturing cost and material saving.A 1.5 kW,9000 r/min axial segmented claw pole motor is designed.The electromagnetic design and temperature distribution of the motor are analyzed to verify the rationality of the design.For the selection of claw pole parameters,the effects of claw pole angle and claw tip length on motor torque,torque ripple and no-load electromotive force are studied,and a suitable selection range is given.The analysis results provide a reference for the development of new products of the new vacuum dry pump drive motor.
