Abstract

This paper describes a novel linear actuator with flat-ring-shaped permanent magnets. A pair of flat-ring-shaped Nd-Fe-B magnets having N and S poles on the surface are put on the same axis and facing each other. By rotating one of the magnets in the direction of its circumference, a rotational field having the direction of the axis occurs and makes a reciprocating force on the other magnet. When this magnet is restricted to linear motion along the axis, the mechanical energy driving the rotating magnet is transferred to the linear motion energy. A pump is made with this mechanism.
