Lightweight Linear Actuator with Concentratedly-placed Stationary Coils

Abstract

This paper presents a novel lightweight linear actuator using permanent magnets and having its coils on the stator concentratedly. The rated force is 6N, 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-and-place actuator of tiny electronic parts, and the performance for the application is confirmed through experiments with a prototype.© 2004, The Institute of Electrical Engineers of Japan.
