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

The disc type birotor permanent magnetic generator that exhaust gas turbine drives
Technical field
The disc type birotor permanent magnetic generator that the present invention provides a kind of exhaust gas turbine to drive belongs to the electric motor of automobile technical field of electric appliances.
Background technology
Auto industry is the sign of modern industry; It is the leading industry of the national economic development; Various aspects in industrial and agricultural production, communications and transportation and human being's production life all play indispensable effect, and fuel converts effective merit at 25%~40% of automobile engine gross energy that combustor inner cylinder produces, and all the other 60%~75% all lose; Wherein the energy taken away of waste gas is 25%~35%, and exhaust energy is recycled and had great importance.As invention disclosed patent: waste gas turbine supercharged power generator; Application number: 02107205.1; Be made up of scheme one permanent magnet and coil windings: permanent magnet is embedded in respectively on the symmetric position of compressor impeller, and its magnetic polarity is arranged just opposite; And keep certain clearance, permanent magnet and coil windings between coil windings and the permanent magnet is the inboard that is fixed on compressor housings; Scheme two: permanent magnet is embedded on the rotor main shaft, and coil windings also is arranged in respectively on the symmetrical position, keeps certain clearance between permanent magnet and the coil windings, and coil windings then is fixed on the middle casing; Scheme three: permanent magnet is embedded in the back of compressor impeller, and coil windings is fixed on the relevant position of middle casing, keeps certain clearance between permanent magnet and the coil windings.This technical scheme is to be bonded on the compressor impeller polylith permanent magnet or on the rotor main shaft or the back of compressor impeller; Because use bonding agent adhesive permanent magnetism body, the bonding agent easy ageing lost efficacy, poor reliability; Damage easily, its serviceability needs further improvement.
Summary of the invention
The purpose of this invention is to provide a kind ofly can overcome above-mentioned defective, compact conformation, disc type birotor permanent magnetic generator that the exhaust gas turbine of take up space exhaust gas driven little, that discharged by engine, energy savings drives, its technology contents is:
Comprise that rotating shaft, gap are sleeved on stator and front end housing and the rear end cap of Bearing Installation in rotating shaft in the rotating shaft; Wherein the stator clamping is positioned between front end housing and the rear end cap; Three's concentric; It is characterized in that: stator by plate-like, the gap is sleeved on the stator support in the rotating shaft and a plurality of iron cores that are tied with armature winding of being inlaid on the stator support are formed; Wherein iron core is distributed on the same circumference of stator support, and the umber of turn of each armature winding equates that the outer cause front end housing and the rear end cap of stator support grip; A disk rotor is all set up in both sides at stator support; Each disk rotor includes one and is fixedly set in the rotor disk in the rotating shaft and is fixed on a plurality of rotor magnetic steels on the rotor disk; Wherein be fixed on a plurality of rotor magnetic steels on the same rotor disk and all be fixed on disk rotor near the end face of stator support and be positioned on the same circumference; The adjacent rotor magnet steel is opposite towards the polarity of the end face of stator support, and certain end play is all arranged between two disk rotors and the stator.
The disc type birotor permanent magnetic generator that described exhaust gas turbine drives, rotor disk all is fixed in the rotating shaft through locking nut, rotor magnetic steel through screw on rotor disk.
Its operation principle is: the rotating shaft of generator and the rotating shaft of turbine are same axle, and the HTHP waste gas that engine is discharged gets into turbine through air inlet and drives the turbine rotation, and the disk rotor that rotating shaft drives separation stator support both sides rotates; It is the magnetic field rotation; The shared armature winding of two disk rotors with stator, the armature winding cutting magnetic line produces electromotive force; The magnetic field that produces superposes in power generator air gap, electric energy is provided for the power consumption equipment of automobile.
The present invention compared with prior art, its advantage is: the rotating shaft of generator and the rotating shaft of turbine are same axle, compact conformation, easy for installation, it is little to take up space, the waste gas of being discharged by engine directly drives, and has practiced thrift the energy, has reduced discharging.
