- Abstract
Electromagnetic design of a moving magnet frictionless linear actuator with self‐holding functionality for mechanical gear shifting in a transmission application is presented. The actuator consists of a tubular magnetic circuit with stationary armature and axially moving rotating permanent magnet assembly with radial magnetisation in the air gap. The armature contains a two‐piece magnetic core with a space for a winding. The effects of armature slot opening and magnetic circuit materials on the self‐holding force and the acting force are studied in the whole moving range. The designed moving magnet linear actuator improves the performance of the vehicle by enabling shift times below 50 ms with no energy consumption between the shifts.
