ABSTRACT:
Retention tang structure (61-64) is provided on the hub (52) of a switched reluctance motor rotor (50) for retaining electrically insulating material (65-68) in gaps (57-60) between the rotor poles (53-56), and minimizing magnetic flux path lines through the tangs. A one-piece unitary harness (92) is also provided and is molded in-situ axially around the laminated rotor stack and further structurally enhances the hold-together strength thereof. The electrically insulating molded material is integrally formed both in the gaps (57-60) between the rotor poles (53-56) and on the axial ends (88, 90) of the laminated stack to provide in combination axial runners (65-68) of molded material extending axially along the gaps (57-60) and integral with annular end rings (94, 96) of molded material on the axial ends (88, 90), which combination structurally enhances the hold-together strength of the laminated stack.
