Abstract
A machine for converting thermal energy originating from waste heat deposits into electrical energy. It uses the magnetic phase transition properties of certain materials when they are exposed to a temperature variation with respect to their Curie temperature. The machine includes a magnetothermal converter provided with a fixed stator provided with active elements made of the materials, and a mobile rotor provided with magnetic poles and non-magnetic poles. The machine includes a closed fluidic circuit of heat-transfer fluid, coupled with two thermal sources of different temperatures by means of heat exchangers and with the stator to transfer thermal energy collected in the active elements. A synchronization system makes it possible to expose the active elements to alternating thermal cycles to generate a permanent magnetic imbalance between the rotor and the stator, and generate a displacement of the rotor, creating mechanical energy that can be converted into electrical energy.
