ABSTRACT:
A magnet for a dynamo-electric machine has a plurality of magnetic poles disposed substantially in a circular shape and opposite a plurality of teeth disposed substantially in a circular shape, the magnetic poles and teeth separated by a gap in an axial direction of a revolving shaft. A plurality of inter-pole sections extend circumferentially between adjacent magnetic poles out of the plurality of magnetic poles. The inter-pole sections have tooth-opposed surfaces that are recessed relative to the surfaces of the magnetic poles opposite the teeth in the direction of the revolving shaft. The plurality of magnetic poles and the plurality of inter-pole sections are integrally formed.
