Abstract

The invention provides an electromagnetic and permanent magnet invisible magnetic pole generator rotor assembly method, which belongs to the technical field of automobile motors and electrical appliances. The permanent magnetic poles on the rotor core and the electric excitation poles are spaced apart from each other, and the permanent magnetic field and the electric excitation magnetic field generated are in the air gap. Internal series synthesis, the magnetic field can be adjusted, and the magnetic field directly faces the air gap, less magnetic flux leakage, and high material utilization rate. By adjusting the magnitude and direction of the electric current of the electric excitation coil, and then changing the magnetic field in the air gap of the generator, the power generation The output voltage of the machine remains stable to ensure the safety and reliability of the automotive electrical equipment.

Description

The stealthy magnetic pole generator amature of electromagnetism and permanent magnetism assembly method

Technical field

The invention provides the stealthy magnetic pole generator amature of a kind of electromagnetism and permanent magnetism assembly method, belong to electric motor of automobile technical field of electric appliances.

Background technology

The assembly method of the rotor of permanent-magnetic power generator using on automobile is at present to adopt axle and a full circle cylindricality permanent magnet assembling to form, again columniform permanent magnet is pressed to radial magnetizing, form the N utmost point, the extremely spaced p-m rotor of S, in the process of magnetizing, magnetism molecule can not reach ordered arrangement completely, remanence strength is low, and between the magnetic pole due to whole cylindrical permanent magnet, a part of permanent magnetic material is inoperative, therefore the permanent magnetic material utilance of this version rotor is low, and because permanent magnetic field is stationary magnetic field, magnetic field is unadjustable, when the slow-speed of revolution, output voltage is low, during high rotating speed, output voltage is high, output voltage is unstable, cause automobile electrical device damage or useful life to shorten, its serviceability needs further improvement.

Summary of the invention

Object of the present invention provides a kind of can overcome above-mentioned defect, and magnetic field is directly in the face of air gap, and stock utilization is high, reliable operation, and starting reactance is little, the stealthy magnetic pole generator amature of the electromagnetism that air gap internal magnetic field can regulate and permanent magnetism assembly method, its technology contents is:

The stealthy magnetic pole generator amature of electromagnetism and permanent magnetism assembly method, it is characterized in that: punching center is with through hole, periphery is with the rotor punching of long T font salient pole and short T font salient pole space, in long T font salient pole external arc with semicircle groove, rotor punching is laminated by the suitable mode of burr one, adopt argon arc welding welding to laminate the semicircle groove of rear rotor punching, form rotor core, on each short T font salient pole of rotor core, there are two identical intrados to be the arc permanent-magnet steel of the N utmost point, arc permanent-magnet steel is fixed in the external arc of the short T font of rotor core salient pole by pole shoe by non-magnetic screw, form combination type permanent-magnet magnetic pole, electricity magnet exciting coil is wrapped on each long T font salient pole, the rule that the polarity producing by the convex surface that passes into long T font salient pole after direct current is the N utmost point winds the line successively, the number of turn on each long T font salient pole should equate, again the collector ring being comprised of two mutual unconnected copper rings and bakelite is fixed on axle, a copper ring of one termination collector ring of electricity magnet exciting coil, another copper ring of another termination collector ring, rotor core is fixed on axle by nut, complete the assembling of the stealthy magnetic pole generator amature of electromagnetism and permanent magnetism.

The present invention compared with prior art, permanent-magnet pole on rotor core and electric field pole space, the permanent magnetic field producing and electricity excitation magnetic field are connected synthetic in air gap, magnetic field can regulate, and air gap is directly faced in magnetic field, leakage field is few, stock utilization is high, by regulating the size and Orientation of electric magnet exciting coil electrical current and then changing the magnetic field size in power generator air gap, make generator output voltage keep stable, guarantee the safety and reliability of automobile electrical equipment.
