Electric machine for use as generator for generating electricity to de-icing circuit of aircraft, has magnetic circuit realized partly by ferromagnetic material having Curie temperature of less than or equal to specific degree Celsius

摘要

The machine (3) has two units (4, 5) i.e. stator and rotor, rotated with respect to each other, where one of the units includes a magnetic circuit (6) and an electrical circuit (7). A magnetic flux variation in the magnetic circuit forms EMF in the electrical circuit. The other unit is provided with a permanent magnet (10). The magnetic circuit is realized partly by ferromagnetic material having a Curie temperature less than or equal to 300 degree Celsius, where the ferromagnetic material includes Gadolinium, nickel or iron alloy.
