Description
Technical field
The present invention is a kind of permanent-magnetic AC synchronous generator with new structure of high power density and compound excitation stabilized voltage characteristic, with gasoline engine or the supporting composition generating set of diesel engine, can be used as portable power supplies and spare emergent power source and uses.
Background technology
At present, gasoline engine generator industry mainstream model is the electric excitation generator type of brush that has based on copper cash and aluminum steel, and power bracket contains 1kW～20kW.Present gasoline engine generator group both domestic and external substantially all be adopt that AVR regulates exciting current the single-phase or threephase alternator of the electric excitation of brush arranged, the sharpest edges of this generator are exactly that automatic adjustment can be realized by regulating rotor excitation current in its magnetic field, thereby make the generator of unit operation keep the stable of output voltage to the gamut of nominal load, its structural principle be described below in conjunction with accompanying drawing in zero load:
Fig. 7 is the traditional electrical excitation AC synchronous generator structural principle schematic diagram that prior art generally adopts, among the figure: label 4 is an external stator principal phase winding, label 5 is an external stator core, label 21 is brush and collector ring, label 22 is the stator auxiliary winding, and label 23 is the AVR excitation voltage regulator, and label 24 is an excitation winding, label 25 is a rotor core, and label 26 is for driving rotating shaft.This type generator core component is stator and each cover of rotor, external stator principal phase winding 4 and excitation winding 24 that copper cash or aluminum steel are made are set on its external stator core 5 and the rotor core 25, external stator principal phase winding 4 external supply capabilities wherein, epitrochanterian excitation winding 24 is used for setting up motor gas-gap magnetic field, make motor produce electromagnetic induction, the stator and rotor iron core belongs to magnetic conductive part, the two heteropolarity magnetic pole and magnetic fields that the electricity excitation produces partly constitute closed magnetic circuit by the rotor core yoke, and rotor core 25 is fixed in and drives in the rotating shaft 26.Simultaneously, for regulating magnetic field, generating set also must dispose parts such as corresponding stator auxiliary winding 22, AVR voltage regulator 23, the brush of introducing rotor current and collector ring 21, the required excitation capacity of the generator of this complete electric excitation mode is bigger, the loss ratio of rotor electricity energized circuit accounts for 55%～65% of the whole losses of motor, therefore the energy efficiency of generator is difficult to improve, and the type generator amature copper consumption also accounts for 55%～65% of the whole copper consumptions of motor, so its cost is also higher, the resource consumption of non-ferrous metals such as copper, aluminium is also big.
China is the abundantest country of rare earth permanent-magnetic material in the world, but also is the country of nonferrous metal resource poornesss such as copper, aluminium simultaneously; Therefore, the application of greatly developing rare earth material has realistic meanings to China.Progress along with control technology, rare-earth permanent-magnet electric machine drives the field in the motor industry and is used widely, the motor product that rare earth permanent-magnetic material is made, and the power density that its unit volume material transmits is big, electric efficiency height and energy consumption is little demonstrates the huge superiority of its rare-earth electric motor; But rare earth permanent-magnetic material is used the 'bottleneck' restrictions that electrical generator fields is subjected to the voltage stabilization technique always, because the generator field that permanent magnetic material is made can't be regulated, thereby cause generator voltage control very difficult, voltage descends very serious behind the motor bringing onto load, and then influence the power generating quality of permanent magnet generator unit, limited the range of application of permanent magnetic material on this type of generator.And, adopt rare earth material to replace electric excitation generator rotor winding simply by the conventional motors convention, also can not fully and up hill and dale utilize rare earth material to transmit the advantage of high-energy-density.Therefore, expand the range of application of rare earth material and just must must solve following technical barrier: one, be the advantage that makes full use of rare earth material, must research and design can transmit the permanent magnet generator new structure of high power density in the portable power source field of independent operating; Two, research overcomes magneto and can't regulate magnetic field and the technological approaches and the effective ways of stable generator voltage.
