Abstract
The invention provides an exhaust turbine driven disk-type double-rotor permanent magnet generator. The generator comprises a rotating shaft, a stator, a front end cover and a rear end cover. The generator is characterized in that the stator comprises stator supports sleeved on the rotating shaft at intervals and a plurality of iron cores embedded on the stator supports; armature windings are wound on the iron cores; the iron cores are uniformly distributed on the same circumference of the stator supports; a disk type rotor is additionally arranged at the two sides of the stator supports respectively and comprises a rotor disk fixedly sleeved on the rotating shaft and a plurality of rotor magnetic steel fixed on the rotor disk; the plurality of rotor magnetic steel fixed on the same rotor disk are fixed on the end faces, close to the stator supports, of the disk type rotors and are arranged on the same circumference; the polarities of the end faces, facing to the stator supports, of the adjacent rotor magnetic steel are opposite; and a certain axial clearances exist between the two disk type rotors and the stator. The generator has the following advantages that: the generator and the turbine share the same rotating shaft, has a compact structure, is convenient to install, takes up little space and is directly driven by the exhaust discharged by the engine, thus saving the energy.
