Abstract

PURPOSE: To obtain a great force, even when low current passes through the coil, by an arrangement wherein only bearing slides on the shaft.
CONSTITUTION: Two permanent magnets 3, 4 in the form of a rectangular parallelepiped are disposed with a space therebetween in such a way that their N-poles are confronting to each other. Center yokes 8, 9 are connected to S-poles of the permanent magnets 3, 4 by circumferential yokes 1, 2, 11 and 12. A movable coil 20 is positioned in a space difined by the permanent magnets 3, 4 and center yokes 8, 9. Depending upon the direction and amount of the current passing through the movable coil 20, the movable coil 20 is moved in the right or left directions, and then a shaft 5 is moved reciprocally.
