Abstract
PURPOSE: To manufacture a compact electricity-during force converter which can be bidirectionally driven and consumes less electric power, by slidably supporting a bobbin having a coil, under the magnetic field of permangnet magnets fixed on the inside surface of a yoke of almost square cross section.
CONSTITUTION: A center pole 1 of square cross section is fixed on the base plate 2' of a yoke 2 of almost square cross section. The side plates 2" of the yoke 2 extend in parallel with one another from the four edges of the base plate 2' and are separated from one another. Permanent magnet plates 3 are provided in prescribed positions on the facing inside surfaces of the side plates 2". A bobbin 4 provided with a coil 5 is slidably supported under a magnetic field produced in a prescribed direction between the inside surfaces of the permanent magnets 3 and the center pole 1. Bidirectional driving is effected by switching the direction of electrical current to the coil 5. The coil 5 whose length is by a travel larger than that of a gap is used to cause a prescribed driving force within the travel.
