Abstract
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.
