Abstract
The invention relates mainly to a starter for a heat engine of a motor vehicle comprising: at least one electromagnetic contactor comprising a positive output terminal, at least one electric motor, the electric motor comprising: at least one brush cage (43), at least one positive brush (35) mounted in the brush cage (43), an electrical path (91) between the positive brush (35) and the positive output terminal (32), and at least one thermal protection (96) situated in the electrical path (91), in which the thermal protection is suitable for disconnecting the two elements (93, 95) when the thermal protection has a temperature above a temperature threshold to electrically disconnect the positive output terminal relative to the positive brush (35).
