ABSTRACT:
Disclosed herein is to a flux reversal motor. The flux reversal motor includes a mover, and a plurality of permanent magnets. The mover moves linearly relative to a stator. A plurality of permanent magnets, having identical polarities, is provided in the end of each mover tooth. The permanent magnets are arranged on the left and right sides of a protrusion of the end of the mover tooth. Thus low noise/low vibration, high speeds, high precision, and high thrust motion can be realized.
