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.
Structure de retenue (61-64) montée sur le moyeu (52) du rotor d'un moteur SRM (50), servant à maintenir l'isolant (65-68) dans les encoches entre les pôles (53-56) du rotor et à y minimiser la pulsation du courant magnétique . Une tôle monopièce est moulée sur place axialement autour de la culasse feuilletée et en améliore la rigidité. L'isolant est moulé directement dans les encoches (57-60) entre les pôles du rotor et sur les extrémités axiales de la culasse feuilletée, et cette combinaison de coulisseaux et de bagues moulées ainsi formés améliorent la rigidité de cette dernière.
