摘要
五相永磁混合式步进电动机是国内近年研制成功并处于进一步发展阶段的一种新型电动机.由于其转子旋转角控制精度高,因而具有较为广泛的应用前景,本文针对五相永磁混合式步进电动机特殊的励磁方式,设计了一种新型的恒力矩(即恒电流)驱动器.所研制的驱动器已在实验室里运行试验成功.
The permanent magnet 5-phase stepping motor with high step angle
accuracy is developed in China. The paper describes a new holding torque (or holding current)driving device according to the special field way for the PM 5-phase motor. It has been successfully used in our laboratory.
