摘要
现代高性能永磁交流伺服系统由驱动控制器、永磁电机及传感器三大部分构成,对其中的高性能永磁交流伺服电机进行了较为全面的总结介绍。在分析现代高性能永磁交流伺服电机的概念、发展历程、技术现状及市场应用的基础上,分别介绍了稀土永磁交流伺服电机的定、转子结构和特点;并对目前流行的分数槽集中绕组永磁交流伺服电机的特点及谐波、齿槽转矩等相关问题进行了简单的讨论;同时对多相永磁交流伺服电机、永磁直线交流伺服电机等其他永磁伺服电机也做了简单介绍;最后针对永磁交流伺服电机在高性能、变频供电、可靠性及系统级设计等各方面的特殊性,讨论分析了其设计特点。
Modem high-performance AC servo systems are composed of three parts： drive controller, permanent magnet motor and sensor, the paper mainly introduced the high-performance AC servo motor. On the basis of the analysis of the concept, development course, technical situation and the application for modem high-performance AC servo motor, introduced separately the structure characteristic of rotor and stator for the rare-earth AC servo motor; discussed the characteristic, harmonic and cogging torque of fractional-slot and concentrated winding AC servo motor; meanwhile brief introduced the multi-phase AC servo motor, PM line- ar AC servo motor and other PM servo motor; finally, aiming at the various aspects particularity of PM AC servo motor in the high-performance, varied-frequency, reliability and system design, analyzed its design characteristic.
