“…In short, if the coils are on the mover [2,3], the amount of copper for the coils can be minimized, but the feeding of electricity to a moving part is needed. If the coils are on the stator [4][5][6], the coils must be placed over the whole range of the mover stroke but the active part for force production is only around the mover.…”

SUMMARYThis paper presents a novel lightweight linear actuator using permanent magnets and having its coils on the stator concentratedly. The rated force is 6 N, the stroke is 30 mm, and the weight is below 300 g owing to its unique structure. The machine is to be applied to, e.g., a pick-andplace actuator of tiny electronic parts, and the performance for the application is confirmed through experiments with a prototype.
