ABSTRACT:
A method of making a core adapted to be used in a dynamoelectric machine. The core has a plurality of slots extending therethrough defining a plurality of first pole sections interposed between adjacent ones of a plurality of integrally interconnected second pole sections, respectively. In this method, a plurality of sets of magnetic material elements are located within the slots generally between the first pole sections and the adjacent ones of the second pole sections, respectively, and a nonmagnetic hardenable material is provided at least within the slots so as to at least in part fill the interstices of the slots generally about the magnetic material element sets in the slots, respectively.
