Abstract
Loose or frayed fibers at the axial end of a fibrous wrap 42 about the periphery of rotor hub 10 mounting permanent magnets 22 are avoided by placing steps 40 between first and second diametral sections 36, 38 in side plates 32, 34 sandwiching the magnets 22 with the wrap preventing radial displacement of the magnets and the side plates preventing axial displacement.
