Abstract
The brush-holder regulator comprises a casing made from an insulating material suitable for being mounted on a rear bearing of an alternator and forming a one-piece assembly with at least one housing suitable for containing brushes allowing an electrical connection to be established with an excitation winding of a rotor of the alternator, an electronic control component (22) connected electrically to a trace circuit (21) overmoulded in the casing, and a cooling radiator (24) for the control component. According to the invention, the control component comprises a back electrode (225) on which the radiator (24) is mounted, the back electrode (225) and the radiator (24) being in electrical and thermal contact and rigidly attached to a portion (216) of the trace circuit.
