Abstract
A rotor assembly for a rotary electric machine including a magnetic shaft provided with at least one pair of equiangularly spaced flats. Non-magnetic spacers abut the flats and a plurality of arcuate permanent magnet segments are disposed about the shaft between the spacers. A plurality of magnetic pole pieces are disposed radially outwardly of a corresponding one of the magnets and are disposed between adjacent spacers. Generally C-shaped channels of non-magnetic material overlie the spacers and interconnect adjacent ends of adjacent pole pieces to hold the components of the rotor in assembled relation.
