摘要:
The invention relates to a current-rectifying arrangement (1) for a multiphase rotary electric machine having a bearing (16, 18) provided with a perforated plate (3) including a heat sink (9) having first current-rectifying elements (8), second current-rectifying elements (10) supported by the plate (3), and a connector (113) inserted between the heat sink (9) and the plate (3), each of the first current-rectifying elements (8) being mounted in a blind cooling cell (A, B, C) defined by a projecting peripheral wall (91, 92, 93) and laterally by two projecting transverse walls extending from the outer periphery to the inner periphery of the heat sink (9), each cell comprising at least one outer hole defined by the inner periphery of the cell, and a transverse passage being provided between two transverse walls opposite two consecutive cells. The rotary electric machine includes such an arrangement. The invention can be used for an automobile alternator.
摘要:
The claw rotor (2) comprises: an axial symmetry axis (X-X); two magnet wheels having a core and teeth (9); insulation (11') for a field coil (10) mounted onto the core; and permanent magnets mounted between two adjacent teeth (9) belonging to one and the other of the magnet wheels, wherein the insulation (11') comprises a hub and a flange on each end of the hub (110), each flange having a plurality of projecting petals for engaging with the angled inner periphery (90) of a tooth (9). At least some petals of a flange (120) corresponding to the permanent magnets (38) are split into a plurality of portions, namely, a main petal (121a) for engaging with the inner periphery (90) of a tooth of the magnet wheel (8) in question and at least one side secondary petal (121b) that is lower, when seen in the radial direction, than the main petal. The rotating electrical machine comprises such a rotor. The invention is of use in a claw rotor for motor vehicle alternator or alterno-starter.

The invention relates to a multiphase rotary electric machine including a bearing (16, 18) provided with a plate (3) that is perforated for the passage of the phase outputs of the machine, of the type that comprises: an electrically conductive heat sink (9) bearing first current rectifying elements; second current rectifying elements (borne by the plate (3)); a connector (113) disposed between the heat sink (9) and the plate (3); and a protective cover on top of the heat sink/connector assembly. The outer periphery of the connector includes faces and hooks (114) for securing the phase outputs. According to the invention, the cover is provided internally with inner dividers which extend into the space defined by the securing portion of the hook and the corresponding face of the heat sink/connector assembly. The invention is suitable for motor vehicle alternators.
