Abstract :
Most surface motors (SFMs) which move on an x-y plane are limited by the moving region because their movers are connected with the wire. The new type surface motor proposed by the authors has no such restriction because the mover is free from the wire connection. The mover can rotate by itself in addition to the liner motion on an x-y plane. This paper presents the principle of operation and improvement of the stator shapes for the increase in thrust of the surface motor. As a result, the SFM´s thrust characteristics have been improved about 25%. Furthermore, the optimum length of the air gap between the mover and the stator is examined
