A claw pole rotor comprises a shaft, first and second polar wheels fastened to the shaft, a winding provided with a winding insulator and surrounded by the first and second polar wheels, a commutator provided with at least one commutator ring, a fan fastened to the first polar wheel and disposed between the winding and the at least one commutator ring, at least one end-of-winding wire being linked to one of the at least one commutator rings, passing through a radial cavity provided between the fan and the first polar wheel. The winding insulator comprises a clip retaining the one end-of-winding wire. The retaining clip is fastened to the winding insulator and comprising crimping means intended to be disposed in the radial cavity to crimp the part of the end-of-winding wire extending into the radial cavity.

Claw rotor comprising clip for securing end wire of winding, and associated electrical machine

A rotary electrical machine ( ), especially a motor vehicle alternator, having a stator ( ) of generally cylindrical annular form, which is arranged in a casing ( ) having a rear portion ( ) and a front portion ( ) in which the outer axial face ( ) of the stator ( ) and the inner axial face ( ) of the casing ( ) define an annular radial space ( ), and the stator ( ) is suspended elastically within the casing ( ), wherein at least part of the annular radial space ( ) contains thermally conductive resin ( ) which is deformable axially and interposed radially between the casing ( ) and stator ( ), so as to effect radial mechanical decoupling between the stator ( ) and casing ( ) and so as to dissipate heat energy from the stator ( ) to the casing ( ).

Rotary electric machine, and in particular motor vehicle alternator, comprising a stator elastically mounted in a heat-conductive resin

The invention relates to a rotary electric machine comprising a rear bearing ( ), an arrangement ( ) for rectifying the current produced by the machine, which comprises a number of positive diodes ( ) supported by a heat dissipater in the overall form of a plate ( ) and a number of negative diodes ( ) supported by support means in the form of a plate advantageously forming part of the rear bearing, the plate ( ) supporting the positive diodes ( ) comprising a great many cooling ribs which have the shape of fins ( ) extending practically radially across the plate, while an opening ( ) for the passage of cooling air is made between each pair of adjacent fins ( ), some fins ( ) extending practically as far as the outer periphery of the support plate ( ).
