This letter presents a bistable permanent magnet actuator, based on double wing magnetic flux (DWMF) formed by the structure of welding sleeve and slotted armature. The double wing magnetic flux consist of high wing magnetic flux (HWMF) and low wing magnetic flux (LWMF), resulting in bistable performance under differentiating control. Parameters improvement around DWMF is analyzed based on modeling, and optimized results for a prototype actuator are obtained. The experimental and simulation results agree well, and show that the prototype actuator can realize bistable performance under the DC step voltage drive, with the holding force of 8.2 N (without current) and the restoring force of −31.7 N (with negative current), the dynamic results show that the displacement response time within 8 mm is 28 ms, of which the actuation time is 16.5 ms, the transient maximum power consumption of the restoring period is 18 W.

基于双翼磁通的双稳态永磁执行器

这封信提出了一种基于双翼磁通量（DWMF）的双稳态永磁执行器，该双翼磁通由焊接套筒和开槽电枢的结构形成。双翼磁通量由高翼磁通量（HWMF）和低翼磁通量（LWMF）组成，在微分控制下产生双稳态性能。基于建模分析了DWMF周围的参数改进，并获得了原型执行器的优化结果。实验和仿真结果吻合良好，表明原型执行器在直流步进电压驱动下可实现双稳态性能，保持力为8.2 N（无电流），恢复力为-31.7 N（负电流），动态结果表明，位移响应时间在8 mm以内为28 ms，其中驱动时间为16.5 ms，
