Applied research status and its key technologies development of the electromagnetic linear actuator

摘要

Firstly, this paper briefly describes the origin of the electromagnetic linear actuator which research status and development are summarised. Secondly, it describes the principle, the characteristics of the moving-coil linear motor and the Moving-magnet linear motor. Thirdly, it analyses and summarizes the key technologies of the electromagnetic linear actuator. One key problem is the matching between electromagnetic force and the load. The other is the influence mechanism of the thermal load on dynamic characteristics. This paper can provide some reference.
