ABSTRACT:
The A phase stator and the A phase stator are opposed each other winding same phase coil thereat. The B phase stator and the B phase stator are opposed each other winding same phase coil thereat. The A phase stator and the A phase stator, and the B phase stator and the B phase stator sandwich the mover, respectively. The mover fixes the permanent magnets having small magnetized pitch on the both surfaces thereof. The permanent magnets on both surfaces of the mover comprises the first permanent magnets and the second permanent magnets. The first permanent magnets having one polarity and a predetermined interval each other along the longitudinal direction of the mover are fixed previously on the mover. The second permanent magnets are inserted to the intervals on the mover.
