A heat generator for reducing emissions includes a permanently magnetized, disc-shaped rotor; a stator axially separated from the rotor and in which the rotor induces electric currents as it rotates to generate heat in the stator; and an adjoining cooling duct through which a cooling liquid flows to dissipate heat generated in the stator. The rotor and stator are axially movable in relation to one another to adjust the heat generated in the stator. Heat output is controlled by a member acting axially on the rotor in the direction of the stator with a variable force against the action of a repelling force, and includes a soft magnetic material forming part of the stator. The permanently magnetized rotor and the stator are magnetically attracted to one another, and it is possible to strengthen/weaken their to achieve a predetermined output/speed profile. |
