Abstract

An apparatus includes first and second movable members for coupling force therebetween and a magnetic flux coupling element. Each of the first and second movable members has an array of magnetic poles. The first and second movable members are arranged concentrically for relative rotation therebetween. The magnetic flux coupling element is arranged between the first and second movable members, thereby providing a flux density region of relatively high magnetic flux density between a pole of the first movable member and a pole of the second movable member. The magnetic flux coupling element is split along an axis orthogonal to a direction of motion of the first and second movable members into a plurality of flux coupling parts.
