Description
The utility model relates to a kind of auto-excitation type automobile permanent magnet alternating current generator.
Motor vehicles such as automobile, tractor nearly all use the automobile silicon rectification AC generator at present, the voltage regulation result of this class generator is good, stable at a high speed, but because of it must connect external power excitation (separated exciting), when the automobile frequent starting, cause the frequency that discharges and recharges of automobile storage battery to increase, make the lost of life of automobile storage battery, and its low-speed performance is relatively poor.People design permanent magnetic generator for vehicle and come into operation for this reason, and the low-speed performance of this generator is good, and non-powered excitation can effectively prolong useful life of automobile storage battery.But its voltage regulation result is not so good, and high speed performance is relatively poor, and structure is complicated.
The purpose of this utility model is to provide a kind of external power excitation that do not need to generate electricity, and low-speed performance is good, high speed is stable, can effectively prolong the automobile storage battery auto-excitation type automobile permanent magnet alternating current generator in useful life.
For achieving the above object, solution of the present utility model is: two pairs of claws are housed in rotating shaft, between a pair of claw magnet exciting coil are housed, another is to being equipped with permanent magnets between the claw, and two pairs of claws constitute two magnetic loops with stator respectively.
The utility model is through probationary certificate, and the non-powered excitation of this generator can be generated electricity, and can reduce the frequency that discharges and recharges of automobile storage battery, prolongs the useful life of automobile storage battery effectively.Have the advantages that low-speed performance is good, high speed is stable, it is simple in structure, volume is little, easy for installation, is convenient to produce in batches.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1---be the structural representation of a kind of embodiment of the utility model.
Fig. 2---be the structural representation of the another kind of embodiment of the utility model.
Fig. 3---be the magnetic circuit schematic diagram of the utility model generator.
Fig. 4---be the schematic diagram of the utility model electric part.
As shown in Figure 1 and Figure 2, the utility model can be made into the auto-excitation type automobile permanent magnet alternating current generator of carbon brush or non-carbonate structure, is made up of claw 1, magnet exciting coil 2, slip ring 3, carbon brush 4, melon seeds 5, rear end cap 6, stator winding 7, stator core 8, front end housing 9, claw 10, permanent magnets 11, claw 12, non magnetic sleeve 13, rotating shaft 14 and electric part the auto-excitation type automobile permanent magnet alternating current generator of carbon brush.Non-carbonate auto-excitation type automobile permanent magnet alternating current generator then only need save the slip ring 3 and the carbon brush 4 of carbon brush structure generator, increases yoke 15 and gets final product.As shown in Figure 4, electric part is made of magnet exciting coil 2, stator winding 7, rectifier bridge 16, adjuster 17, and two outputs of adjuster 17 link to each other with the two ends of magnet exciting coil 2 respectively, changes the sense of current of magnet exciting coil 2 by adjuster 17.Non magnetic sleeve 13 is contained in the rotating shaft 14, the a pair of claw 10,12 that permanent magnets 11 is housed is contained on the non magnetic sleeve 13, if rotating shaft 14 adopts non-magnet material to make, can save non magnetic sleeve 13, the a pair of claw 10,12 that permanent magnets 11 directly will be housed is contained in the rotating shaft 14, and a pair of claw 1,5 that magnet exciting coil 2 is housed also is contained in the rotating shaft 14.Constitute a magnetic loop by claw 1, magnet exciting coil 2, claw 5 with stator, and claw 10, permanent magnets 11, claw 12 and stator constitute another magnetic loop, the air gap useful flux that permanent magnets 11 produces is φ δ
1, the air gap useful flux that magnet exciting coil 2 produces is φ δ
2(see figure 3) is as long as generator rotates, even there is not the external power excitation, because air-gap flux φ δ
1Existence, generator can generate electricity, the power of its output makes magnet exciting coil 2 connect forward exciting current Ie, the air gap useful flux φ δ of generation by adjuster 17
2(self-excitation), the air-gap flux φ δ that magnet exciting coil 2 produces
2Air-gap flux φ δ with permanent magnets 11 generations
1The direction unanimity, power generator air gap useful flux φ δ=φ δ
1+ φ δ
2, power generator air gap useful flux φ δ increases, and the external power output of generator increases.Because the air-gap flux φ δ that permanent magnets 11 produces
1Direction be changeless, therefore the direction that changes exciting current Ie by adjuster 17 can realize the control to generator voltage.When generator voltage was on the low side, adjuster 17 control exciting current Ie forwards passed through magnet exciting coil 2, the air-gap flux φ δ that magnet exciting coil 2 produces
2Direction and the air-gap flux φ δ that produces of permanent magnets 11
1Direction identical, power generator air gap useful flux φ δ (φ δ=φ δ
1+ φ δ
2) increase, generator voltage is raise.When generator voltage was higher, adjuster 17 control exciting current I oppositely passed through magnet exciting coil 2, the air-gap flux φ δ that magnet exciting coil 2 produces
2Direction and the air-gap flux φ δ that produces of permanent magnets 11
1Direction opposite, power generator air gap useful flux φ δ (φ δ=φ δ
1-φ δ
2) reduce, the voltage of generator is reduced.So repeatedly, the voltage of assurance generator output end F is stabilized in rated value.
