概要

Many kinds of surface motors (SFM) which have the ability of the surface motion have been proposed. However, most of all the SFM have the limitation of the movable region because the movers used in it have the electrical wires for supplying operation current. The authors already proposed a new type SFM which does not need to connect the wires to the mover. The most advantageous feature of this new type SFM is that the mover can rotate itself in addition to linear motion on the plane. In order to improve the operation characteristics, the modification focused on the stator shape on the SFM have been already reported. In this paper, the structure of the magnetic poles of the mover is studied.
As a result, the characteristics of thrust can be improved by modifying the structure of the mover poles.
The calculated results agreed well with the experimental one and the effectiveness of the modified structure is confirmed.
