Abstract

Belonging to technical area of electrical motor and appliance of automobile, the disclosed brushless generator is driven by exhaust turbine. The generator is composed of rotor, stator, front end plate, back end plate, turbine, and shell of turbine. Rotor of generator is in structure of electric excitation type brushless claw pole. Through bolt, the shell of turbine is fixed on back end plate of generator. Output shaft of turbine and rotor shaft of generator is a same axis. Advantages are: compact structure, small space taken up, easy of installation. Moreover, generator is driven by exhaust gas from engine so as to save energy.

Description

Wastegas turbine driven brushless generator

Technical field

The invention provides a kind of Wastegas turbine driven brushless generator, belong 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 the generator of automobile use is at present directly driven by engine, consumes bigger effective power.Patent of invention as Chinese patent communique bulletin in 8 days Augusts calendar year 2001: voltage stabilization permanent magneto generator, application number: 00112053.0, by casing, support, line shaft, rotor, permanent magnetic steel, stator, stator winding, stator seat, the stator slip cap, balancing spring, anti-rotation attachment screw, sliding shoe, regulate rotating shaft, location bearing, regulate compositions such as rotating shaft driving mechanism and automatic feedback control circuit, power rotation axis is fixed on the support by location bearing, rotor is fixed on the power rotation axis, one end of stator slip cap is fixed on the support, have groove on the stator slip cap vertically, balancing spring is arranged in the stator slip cap, one end of this spring is stopped by an end face of stator slip cap, other end ejection places the sliding shoe in the stator slip cap, fixedly connected by the anti-rotation attachment screw that passes the slip cap groove between this sliding shoe and the stator seat, this sliding shoe center is screw thread with an end of regulating rotating shaft and flexibly connects, the detection signal input of automatic feedback control circuit is connected to the stator winding output, and the control signal output ends of this circuit is connected to the controlled terminal of driving mechanism.This voltage stabilization permanent magneto generator complex structure, the cost height, its serviceability needs further improvement.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can overcome above-mentioned defective, compact conformation, it is little to take up space, non-carbonate slip ring structure, and failure rate is low, by the exhaust gas driven that engine is discharged, the Wastegas turbine driven brushless generator of energy savings, its technology contents is:

Be made up of rotor, stator, front end housing, rear end cap, turbine, volute, it is characterized in that: on the axle turbine and electric excitation rotor are installed, turbine is installed in volute central authorities, is fixed on the axle by nut, and volute is by being bolted on the commutator end bearing support bracket; The electricity excitation rotor is the brush-free claw-pole structure, form by axle, rotor yoke, the fore paw utmost point, the rear solid end utmost point and excitation winding, excitation winding is wrapped on the rotor yoke, rotor yoke by screw on front end housing, the fore paw utmost point is welded on rear solid end by non-magnet material and extremely goes up, and forms the N utmost point, S interpolar every arrangement, and number of poles equates, and all evenly distribute along circular, the rear solid end extreme pressure is contained on the axle.

Its operation principle is: the HTHP waste gas that engine is discharged enters turbine by air inlet and drives the turbine rotation, turbine rotates by axle drive generator amature, i.e. magnetic field rotation, armature winding cutting magnetic line, produce electromotive force, power supply is provided for the power consumption equipment of automobile.

The present invention compared with prior art, turbine cylinder is by being bolted on the commutator end bearing support bracket, the output shaft of turbine and the armature spindle of generator are same axle, compact conformation, and it is little to take up space, easy for installation, the non-carbonate slip ring structure of this generator, failure rate is low, and the exhaust gas driven of being discharged by engine, save the energy, reduced cost.
