A heat generator for a motor vehicle comprises a rotor ( 1 ), a stator ( 13 ) in which the rotor ( 1 ) induces by rotation electrical currents that generate heat in the stator ( 13 ), and a coolant duct ( 16 ) adjacent to the stator ( 13 ) through which flows a liquid for extracting the heat generated in the stator ( 13 ). A device for regulating the working temperature of a liquid-cooled internal combustion engine comprises such a heat generator and an actuator ( 19 ) for the stator ( 13 ) for regulating the heat generated by the stator ( 13 ) by changing the distance between the stator ( 13 ) and the rotor ( 1 ). The stator ( 13 ) is mounted to be pivotal relative to the rotor ( 1 ) for changing the distance between them and thus for regulating the heat generated in the stator ( 13 ) and regulating the working temperature of the internal combustion engine ( 3 ).
