Abstract
A rotor assembly is provided in which a permanent magnet rotor is used in conjunction with a wound stator member. A containment fixture or cup, receives one or more permanent magnets. The containment fixture has an annular end wall, a circumferential side wall and a circumferential lip. The lip serves to provide a high degree of rigidity and rotational stability to the containment fixture. The magnets abut both the lip and the side wall and the rigidity of the fixture prevents flexing and breaking of the magnets even at high rotational speeds.
