Title:
SYSTEM FOR PROTECTING AGAINST HEATING FOR A ROTATING ELECTRIC MACHINE, IN PARTICULAR A STARTER
Document Type and Number:
WIPO Patent Application WO/2013/001236
Kind Code:
A3
Abstract:
The invention relates to a rotating electric machine including at least a first terminal and a second terminal, and an electric circuit connected to said two terminals, the electric circuit including a field winding in the rotor. The rotating electric machine also includes a thermal protection device (7) arranged in the electric machine, including a first electric conductor (71) electrically connected to the second terminal, and a heat-sensitive member (8) electrically disconnected from the electric circuit and arranged in the electric machine so as to deform above a predetermined temperature. In the electric machine, above a predetermined temperature, the deformation of the heat-sensitive member (8) mechanically activates a connection means (72) of the thermal protection device (7) in order to electrically connect the first electric conductor (71) to a second conductor of the electric circuit that is connected electrically directly upstream of the field winding, the second conductor having a different electric potential than that of the second terminal prior to the activation of the activation means.
