Problems solved by technology

The technical solution is to bond multiple permanent magnets on the compressor impeller, or on the rotor main shaft, or on the back of the compressor impeller. Since the permanent magnets are bonded with an adhesive, the adhesive is prone to aging and failure, poor reliability, and easy Damaged, its performance needs to be further improved

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.

Description

technical field [0001] The invention provides a disc-type double-rotor permanent magnet generator driven by an exhaust gas turbine, which belongs to the technical field of automobile motors and appliances. Background technique [0002] The automobile industry is a symbol of modern industry and a leading industry in the development of the national economy. It plays an indispensable role in all aspects of industrial and agricultural production, transportation, and human production and life. The total energy generated by the combustion of fuel in the cylinder of an automobile engine 25% to 40% of the energy is converted into effective work, and the remaining 60% to 75% are lost. Among them, the energy taken away by the exhaust gas is 25% to 35%. The energy recovery and utilization of the exhaust gas is of great significance. Such as the published invention patent: exhaust gas turbocharger generator, application number: 02107205.1, which is composed of permanent magnets and coil...
