Summary of the invention
The object of the present invention is to provide and a kind ofly can overcome above-mentioned defective, compact structure, it is little to take up space, and does not have electric exciting winding, non-carbonate slip ring structure, rate of fault is low, output voltage stabilization, regulator rectifier circuit is simple, by the exhaust gas driven of vehicle motor discharge, the vehicle waste gas driving three-phase generator of energy saving, it is realized by following content:
Comprise by rotor, stator, front cover, rear end cover, turbine, volute and forming that on the axle turbine and p-m rotor are installed, turbine is installed on the volute, is fixed on the axle by nut, volute is by being bolted on the commutator end bearing support bracket; The armature winding of stator is the identical armature winding of three-phase, every phase armature winding in the three-phase all strides across three utmost points rule successively on the stator iron core respectively, the phase difference of above-mentioned armature winding is 120 degree, the head end of above-mentioned armature winding is connected to the cathode output end of generator, and the tail end of above-mentioned armature winding connects the input end of rectifying pressurizer respectively; On every permanent magnet on the p-m rotor and the stator iron core per three extremely corresponding, some permanent magnets by pole shoe by non-magnetic conduction screw on rotor iron core, the N utmost point of adjacent permanent magnet and S interpolar are formed p-m rotor every arrangement; Rectifying pressurizer is three phase half wave rectification voltage stabilizer or three-phase half controlled bridge formula rectifying pressurizer; Permanent magnet is the NdFeB magnetic material.
Working principle: the High Temperature High Pressure waste gas that vehicle motor is discharged enters turbo machine by suction port and drives the turbine rotation, turbine is by the rotation of axle drive generator amature, it is the magnetic field rotation, the armature winding cutting magnetic line, produce electromotive force, the identical electric current of three-phase that the identical armature winding of three-phase produces, phase difference is 120 degree, the identical electric current of described three-phase is by the rectifying and voltage-stabilizing effect of three phase half wave rectification voltage stabilizer or three-phase half controlled bridge formula rectifying pressurizer, the output direct current of voltage regulation, the power supply of vehicle electric consumer can be directly be, also the Vehicular accumulator cell charging can be directly be.
The advantage of comparison prior art of the present invention is:
1, volute is by being bolted on the commutator end bearing support bracket, and the axle of turbo machine is a same axle with the axle of generator, compact structure, and it is little to take up space, easy for installation, and the waste gas of being discharged by motor directly drives, and has saved the energy, has reduced cost.
2, adopt threephase armature winding permanent magnet generator structure, by three phase half wave rectification voltage stabilizer or three-phase half controlled bridge formula rectifying pressurizer rectifying and voltage-stabilizing, make generator in wide speed range, the direct voltage output galvanic current, the power supply of vehicle direct-flow current consumer be can directly give, Vehicular accumulator cell or super capacitor charging also can be given.
3, adopt threephase armature, the number of phases is many, and frequency is low, and every phase winding number of turn is few, and the armature winding synchronous reactance is little, so reactive loss is few, and effective output is big.
4, the present invention adopts the NdFeB magnetic material to make rotor magnetic pole, and advantage is,
(1) NdFeB magnetic property excellence is the highest material of magnetic energy product in the present rare earth permanent magnet, make general used Ferrite Material magnetic pole ten surplus times, cause that magnetic is strong, can reduce the use of permanent-magnet material, reduced cost, improved performance and cheap;
