摘要： A drive member is rotatable or movable straight on a principle different from the principle of conventional three-phase or single-phase induction motors. The drive member 4 of the device of the invention is made of electrically conductive nonmagnetic material, supported rotatably or movably straight and uniform in wall thickness and width. An outer magnetic member 2 and an inner magnetic member 3 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 22 or 32 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 smaller width than the drive member and are arranged centrally of the drive member, so that the drive member has edge portions 41, 41 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 phase differences are produced at the respective poles of the magnetic circuits, each flux generates an induced current in the drive 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.
