Abstract |
Several types of surface motors
(SFMs) which have the ability to perform
surface motion have been proposed. However,
most SFMs are limited in movement, because
the movers used depend on electrical wires to
supply the operating current. The authors have
proposed a new type of SFM that does not
require wires to be connected to the mover. The
most advantageous feature of this new type of
SFM is that the mover can perform rotation in
addition to linear motion on a plane surface.
This SFM could be used for applications in a
sealed space, because the mover and the stator
are completely separate. In this paper, the
structure of this SFM and the movement
principle are described. The torque
characteristics of each excitation pattern are
experimentally measured, and, as a result, the
optimum excitation pattern for rotational motion
is obtained. |
