Dynamo-electric machine, in particular an alternator for a motor vehicle

Abstract

Abstract 1. A dynamo-electric machine, and more particularly an alternator for an automotive vehicle, of the kind comprising a rotor (4) and a stator (1) comprising a stack of laminations assembled rigidly together, in the bore of which the rotor rotates, the rotor being itself rotatably mounted in the bearings of two end plates (2) and (2_a), the said stator (1) being mounted in the extension constituting a housing sleeve (2_c) of at least one of the said end plates (2), the end plates (2) and (2_a) being secured by means of tie bolts (9) against the said stator (1), the stator being itself secured within the housing sleeve (2_c) of one of the end plates (2) by means of a spacer (8) of shock absorbing material, for example rubber or plastics material, inserted between the said sleeve (2_c) and the outer periphery of the stator, so as to straddle all or part of the said stator (1), characterised in that the spacer (8) of schock absorbing material comprises two shouldered rings (8 and 8_a) which cover respectively the two peripheral end faces of the stator (1).
