Reluctor for polyphase rotating machine, has annular magnetic part, where reluctor is rotatably integrated in translation with rear end of shaft of electric machine via inner ring of rear ball bearing

摘要

The reluctor has an annular magnetic part maintained by an outer periphery of a steel core. The reluctor surrounds a shaft of a polyphase rotating machine. The reluctor is rotatably integrated in translation with a rear end of the shaft of the electric machine via an inner ring (136) of a rear ball bearing (36) which is locked on the rear end of the shaft, which maintains the integration of the reluctor with the bearing.
