Hybrid Tunable Magnet Actuator: Design of a Linearized Force-Flux Tunable Magnet Actuator

Recent studies have shown that tunable magnets (soft permanent magnets) can significantly reduce Joule heating in electromagnetic actuators. To achieve high motion accuracy and repeatability, this article proposes a novel actuator design with a linearized force-flux relation. In prior designs of variable reluctance tunable magnet actuators,...
