ABSTRACT:
The novel rotor or stator comprises a symmetrical assembly of permanent-magnet segments, the working faces of which are separated. Each segment is magnetized to have one pole extending across one-half of its working face and the opposite pole extending across the other half. Because adjacent halves of adjacent working faces have like polarity, it appears that flux emanating from the segments between adjacent magnet segments is redirected more orthogonally with respect to the working faces, thus enhancing efficiency. The segments may either be parts of a single permanent magnet or individual pieces, and their working faces may together define either a cylinder or a plane.
