Abstract
A rotor assembly includes a rotor core having winding slots, and one or more coils, which have slot-inserted segments included in the winding slots, and first and second end-turn segments external to the winding slots and located around opposite axial ends of the rotor core, respectively. The rotor assembly further includes a first containment band located around at least a portion of the first end-turn segments and configured to prevent the first end-turn segments from moving away from the rotor core radially, a second containment band located around at least a portion of the second end-turn segments and configured to prevent the second end-turn segments from moving away from the rotor core radially, and one or more sticks mounted in one or more of the winding slots, respectively. The first and second containment bands are retained via the sticks against moving away axially.
