永磁交流伺服电动机
20世纪80年代以来,随着集成电路、电力电子技术和交流可变速驱动技术的发展,永磁交流伺服驱动技术有了突出的发展,各国电气厂商相继推出各自的交流伺服电动机和伺服驱动器系列产品并不断完善和更新。交流伺服系统已成为当代高性能伺服系统的主要发展方向,使原来的直流伺服面临被淘汰的危机。90年代以后,世界各国已经商品化了的交流伺服系统是采用全数字控制的正弦波电动机伺服驱动。交流伺服驱动装置在传动领域的发展日新月异。
永磁交流伺服电动机同直流伺服电动机比较,主要优点有:
⑴无电刷和换向器,因此工作可靠,对维护和保养要求低。
⑵定子绕组散热比较方便。
⑶惯量小,易于提高系统的快速性。
⑷适应于高速大力矩工作状态。
⑸同功率下有较小的体积和重量。
