<P>PROBLEM TO BE SOLVED: To attain reduction of material costs without reducing the performance of a revolving armature. <P>SOLUTION: In a revolving armature, a field core is formed in a rectangular frame shape from a pair of side parts formed in a steel plate drawing direction and a pair of side parts formed in a direction orthogonal with the steel plate drawing direction. Each of the side parts formed in the steel plate drawing direction is made wider than a width of each of the side parts formed in the direction orthogonal with the steel plate drawing direction, namely, formed in a hoop width direction, and each of the side parts in the steel plate drawing direction includes a projecting pole around which a field winding wire is wound. <P>COPYRIGHT: (C)2012,JPO&INPIT |
