CURRENT RECTIFYING ARRANGEMENT FOR A ROTARY ELECTRIC MACHINE, COMPRISING AT LEAST TWO MODULES, AND ROTARY ELECTRIC MACHINE COMPRISING SUCH AN ARRANGEMENT

摘要

The disclosed current rectifying arrangement (100A) comprises a bearing that is part of a multiphase rotary electric machine and electrically insulates at least two modules, each of which has a part (16-10') that includes a piece (10') for supporting current rectifying elements (93, 94) and a heat dissipator (16), the outer periphery of which is provided with a base (19) rigidly connected to the first piece. On at least one of the circumferential ends of its base (19), each module (100A) has a mounting zone in the form of a projection (701, 702) for connection to the other module. Said projections are designed to be placed on top of each other and are bored (590) so as to allow a fixing member to penetrate therethrough in order to mount the modules on the bearing, electric insulation means (592, 593) being placed between the two projections (701, 702). Said means comprise a sleeve (592) which penetrates the aligned bores (590) of the projections (701, 702) and is provided with a collar (593) that is to be inserted between the ends of the two projections (701, 702). The multiphase rotary electric machine is characterized in that it holds such an arrangement. Application: motor vehicle alternator.
