What is it about?
The characteristics of magnetic flux are the key factors to design bistable actuator. The proposed double wing magnetic fluxes 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 bistable actuator is suitable for the field with strict requirements on power consumption.

Why is it important?
Taking advantage of welding sleeve and slotted armature, DWMF consist of HWMF and LWMF. DWMF changes at holding position are able to realize bistable performance under different polarity voltage control strategy.
