Abstract
An agricultural motor vehicle generator structurally adopts a permanent magnet three-phase multi-pole alternating current generator, and an end cover 1 is fixedly connected with a shell 4 through a bolt 10. A stator 5 is mounted in the housing 4. The rotor 6 is mounted on the rotating shaft 7 through a magnetic isolation sleeve 11. The rotating shaft 7 is arranged on the end cover 1 through a bearing 2. The end cover 1 is provided with a pressure regulator 8. The voltage regulator 8 is a three-phase frequency reactor having a core shaped like a Chinese character ri. The iron core is a solid iron block 11, and three coils 12 are wound on the iron block. The permanent magnet material in the three-phase multipolar alternating current motor is Ru FeB. The utility model has the advantages that the engine speed can not cause the big fluctuation of generator voltage when changing greatly.
Description
The utility model relates to generator, especially a kind of Agricultural automotive vehicle generator.
The Agricultural automotive vehicle lighting generator has DC generator, single-phase three road generators of permanent magnetism at present.Flywheel magneto, the single-phase single channel generator of permanent magnetism and two silicon rectification generator of encouraging must be joined storage battery when DC generator is used and just can be reached satisfied effect.The output voltage of single-phase three road generators of permanent magnetism, flywheel magneto and the single-phase single channel generator of permanent magnetism all changes with the operating state of tractor, and therefore, these generators can not guarantee enough illuminances when low speed driving, easily cause the accident.In addition, the used magnetic patch of single-phase three road generators of permanent magnetism is strontium and barium ferrite at present, and these magnets are subject to mechanical oscillation or temperature action reduces magnetic field intensity gradually, causes generator power to descend.Two silicon rectification generators of encouraging are to develop on the basis of silicon rectifying generator for automobile, and it has solved is not having it to encourage the problem of can not building voltage under the power supply situation, but its low-speed performance is poor, and the voltage degree of stability is still undesirable.
The purpose of this utility model is the problem at the low-speed performance difference of the various generators existence of present Agricultural automotive vehicle, provide a kind of and can guarantee certain illuminance when the speed of a motor vehicle is minimum, the reason motor speed is too high and burn out the Agricultural automotive vehicle generator of lighting bulb yet when the speed of a motor vehicle is the highest.
The utility model is achieved in that the Agricultural automotive vehicle generator adopts the multipole alternator construction of permanent magnetism three-phase, comprises end cap, shell, rotor, stator etc.End cap is connected with bolt and shell.Stator is housed in the shell.Rotor is fixed in the rotating shaft by magnetic shield.Rotating shaft is bearing on the end cap by bearing.There is a voltage regulator in the end cap outside by voltage regulator is box-packed.
Said voltage regulator is a three-phase frequency reactor, and the iron core of " day " font is solid whole iron block.Three coils and are connected with the stator winding of generator respectively respectively on three of " day " font iron core parallel cylinders unshakable in one's determination.
Permanent magnet material in the multipole alternating current generator of permanent magnetism three-phase is for making up iron boron.
Because the power output of generator increases with the rotating speed of generator, and rotating speed and frequency are directly proportional, the solid whole iron block three-phase frequency reactor that constitutes unshakable in one's determination is because eddy current causes energy loss, cause its output electric energy and frequency to be inversely proportional to, thereby this Agricultural automotive vehicle generator can have the very little voltage output of fluctuation in the very big range of speeds.In addition, adopt ferromagnetic woman's persona iron boron to replace ferrite on the present permanent magnet generator, the low-speed performance of generator is improved greatly, and the generator volume is dwindled greatly.
With present widely used single front wheel tractor is example, because generator power is directly proportional with rotating speed, car just slows down when road conditions are bad, can not guarantee illuminance, on the contrary path formation, and when the speed of a motor vehicle was too high, output of a generator increased, and burns out bulb easily.After using the utility model, no matter the speed of a motor vehicle just all can keep normal illumination, and in other words, engine speed is when changing for 300 rev/mins-2000 rev/mins, and the voltage fluctuation of generator is 11.2 volts-13.2 volts, meets lighting requirement fully.
Fig. 1 is a structural map of the present utility model;
Fig. 2 is the structural map of the utility model voltage regulator.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the Agricultural automotive vehicle generator is the multipole alternating current generator of a kind of permanent magnetism three-phase, and its structure is basic identical with the structure of wind-driven generator, and it comprises end cap 1, shell 4, rotating shaft 7, rotor 6 and stator 5.End cap 1 and shell 4 are fixed together by bolt 10.Stator 5 is housed in the shell 4.Rotor 6 is fixed in the rotating shaft 7 by magnetic shield 11.Rotating shaft 7 is bearing in the bearing 2 of end cap 1.By voltage regulator box 9 voltage regulator 8 is housed on the end cap 1.Voltage regulator 8 is the three-phase frequency reactors with " day " shaped iron core.It comprises the solid whole iron block 11 of " day " font and around thereon three coils 12.Permanent magnet material in the multipole alternating current generator of permanent magnetism three-phase is the Ru-Fe-Mn with ferromagnetism energy.
