According to the invention, configurations of X-windings and Y-windings in
a synchronous permanent planar motor are improved, X-windings and
Y-windings overlap in the direction normal to the planar magnet array and
distribute on the entire surface of the thrust core, such that effective
wires in the X-windings and Y-windings are lengthened and increased in
number, therefore the electromagnetic force generated by the SPMPM of
this invention is increased correspondingly; X-windings and Y-windings
are mounted on a thrust core made of iron material, thus the
electromagnetic force is further increased; in addition, two separated
anti-yawing member are provided on the mover for counteracting yawing of
the mover, accordingly interference between anti-yawing torque and the
electromagnetic force for propelling is eliminated.
