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; The generator present and automobile accessories use, ubiquity the phenomenon of low speed illuminating effect difference, can not satisfy user's instructions for use.Patent of invention like Chinese patent communique bulletin in 8 days Augusts calendar year 2001: voltage stabilization permanent magneto generator; Application number: 00112053.0; Form by casing, support, line shaft, rotor, permanent magnetic steel, stator, stator winding, stator seat, stator slip cap, balancing spring, anti-rotation attachment screw, sliding shoe, adjusting rotating shaft, location bearing, adjusting rotating shaft driving mechanism and automatic feedback control circuit etc.; Power rotation axis is fixed on the support through location bearing, and rotor is fixed on the power rotation axis, and an 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, and an end of this spring is stopped that by an end face of stator slip cap other end ejection places the sliding shoe in the stator slip cap; Be 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, and the detection signal input of automatic feedback control circuit is connected to the stator winding output, and this circuit control signal output part is connected to the controlled terminal of driving mechanism.This voltage stabilization permanent magneto generator complex structure, cost is high, and its serviceability needs further improvement.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can overcome the common excitation of above-mentioned defective, permanent magnetism and electromagnetism; The magnetic field that produces is connected synthetic in power generator air gap, and magnetic field intensity is big, and generator power density is high; Automobile easy to install and use is with composite poles formula compound rectifier excitation TRT, and its technology contents is:

The automobile of being made up of rotor, stator, front end housing, rear end cap, electronic voltage regulation controller is with composite poles formula compound rectifier excitation TRT, the shared same rotor core of radial permanent magnet field and salient pole electromagnetic field, and the magnetic field of generation is connected synthetic in power generator air gap;

Rotor is made up of tile magnet steel, pole shoe, screw, rotor core, axle, electric excitation winding, and rotor is the combined magnetic electrode structure very, and multi-disc tile magnet steel is arranged on each rotor pole; The convex surface polarity of every tile magnet steel is identical, through pole shoe by screw on the cylindrical of rotor core, adjacent rotors utmost point convex surface polarity is opposite on the rotor; Rotor core is fitted on the axle, and the coil of electric excitation winding is wrapped on the salient pole of rotor core, is that the N utmost point, S utmost point rule separately wind the line successively by feeding the polarity that the convex surface of salient pole produces behind the direct current; The number of turn on each salient pole should equate; Carbon brush is connected with electronic voltage regulation controller, and slip ring is connected with electric excitation winding, and carbon brush, slip ring are installed in the left side of rear end cap; Slip ring is fixed on the axle, and the outside diameter of slip ring is less than the diameter of bore of bearing.

Described automobile is with composite poles formula compound rectifier excitation TRT, and the tile magnet steel on each rotor pole has 3.

Operation principle: automobile engine drives generator pulley and rotates, i.e. rotor field rotation, and the armature winding cutting magnetic line produces electromotive force, for the electricity consumption facility of automobile provides electric energy.

The present invention compared with prior art, generator amature adopts the combined magnetic electrode structure, has reduced the generator resistance of start and operation noise; And the shared same rotor core of radial permanent magnet field and salient pole electromagnetic field; The magnetic field that produces is connected synthetic in power generator air gap, and magnetic field intensity is big, and generator power density is high; Pass through to regulate the size and Orientation of salient pole electricity excitation rotor electrical current during work; Magnetic field behind permanent magnetic field and the electric exciting field superposition can be regulated, and generator output voltage in wide rotating speed, wide loading range keeps stable, but suit is used generator in Hyundai Motor.
