Title:
HEAT GENERATOR FOR A MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO2000078569
Kind Code:
A3
Abstract:
A heat generator for reducing emissions from motor vehicles comprises a permanently magnetised, disc-shaped rotor (9, 12, 13); a stator (20, 22, 23), which is axially separated from the rotor and in which the rotor induces electric currents as it rotates, which generate electric currents, which generate heat in the stator, and a cooling duct (21) adjoining the stator and intended for a flowing liquid in order to dissipate the heat generated in the stator. The rotor (9, 12, 13) and the stator (20, 22, 23) are mounted to be axially moveable in relation to one another in order to adjust the heat generated in the stator. Means (15, 16, 19, 27, 28, 37, 38, 40) are arranged for determining the heat output generated in the stator by acting axially on the rotor in the direction of the stator with a variable force against the action of a repelling force, which is generated by the currents induced in the stator.
