ABSTRACT:
A drive member of the device is made of electrically conductive non-magnetic material, supported rotatably or movably straight and uniform in wall thickness and width. An outer magnetic member and an inner magnetic member are arranged respectively at the outer side and the inner side of the drive member which are orthogonal to the direction of movement thereof. At least one of the outer and inner magnetic member has at least three magnetic poles to provide closed magnetic circuits extending from the respective poles and penetrating the drive member and the magnetic members along a round path. The poles have a width less than that of the drive member and are arranged centrally around the drive member, so that the drive member has edge portions which are not opposed to the poles, at opposite sides thereof which are orthogonal to the direction of movement. When fluxes with at least three different phases are produced at the respective poles of the magnetic circuits, each flux generates an induced current in the drive member, whereby an electromagnetic force acting on the drive member is produced between the flux and the current to move the drive member relative to one or both of the outer and inner magnetic members.
