ABSTRACT:
Having a core wound with the magnetizing winding, and a yoke separated from the core, and an armature which has the permanent magnets, both pole pieces of the core and the facing-surfaces of the yoke being positioned apart in a predetermined space; in said space the magnetic poles of the permanent magnets being stationed; and through a joint-work of the magnetic flux created by the magnetizing winding and the armature flux created by the permanent magnets the armature is made to relatively reverse-displace against the core and the yoke.
