An annular magnet assembly for a dynamoelectric machine includes a plurality of arcuate permanent magnets disposed in an annular array and a frame member of a non-magnetic material for rigidly connecting the magnets together. The magnets are disposed in end-to-end abutment to form the annular array, both ends of each magnet being cut to form a recess in the inner or outer peripheral surface of the annular array at the respective abutments of the magnets. The frame member comprises a pair of annular portions which tightly engage the opposite sides of the annular array and ledge portions extending through the recesses to connect the pair of annular portions together.
