Abstract
The utility model relates to a permanent magnetic voltage-constant generator with flying wheels, which is the improvement to permanent magnetic generators with flying wheels. The utility model adds permanent magnet quantity and stator coil quantity on a rotor, and is also provided with an electronic regulator for voltage stabilization. The utility model enhances magnetic efficiency of the generator. When an engine does low-speed operation, lighting fixtures has better luminous effect. Because the electronic regulator takes effect when the engine does high-speed operation, the output voltage of the generator is constant voltage, which prolongs service life of illuminating lamp and guarantees safe operation of vehicles.
Description
The utility model is the improvement to generator with flywheel.
At present, with hand tractor, the illumination flywheel type permanent-magnet generator that agricultural tricycle is supporting, its structure is roughly rotor and is provided with 6 blocks of permanent magnets, corresponding on the stator 6 coils are housed, because design, its output voltage only is about 30% of a rated voltage.When the diesel engine idling, generator output voltage is lower, makes the tractor night work, meeting, and when low speed driving such as turning or the road surface situation is relatively poor, the lighting brightness deficiency influences safety work.
For fear of above-mentioned weak point, the purpose of this utility model is to provide a kind of fly-wheel type permanent magnet constant voltage generator, structurally increase the quantity of magnetic pole and stator coil, and the effect of electronic controller, make tractor at low speed or when running at high speed, all can guarantee the output of generator constant voltage, have enough brightness of illuminations, realize safety work.
For achieving the above object, the utility model has adopted following technical measures.The fly-wheel type permanent magnet constant voltage generator, comprise by rotor case 2, non-magnetic fixed piece 3, the rotor assembly that permanent magnet 4 constitutes and by stator core 5, the field frame assembly that coil 6 and stator core support 7 constitute is formed, rotor assembly is installed on the diesel engine flywheel through rotor mount hole 1, and field frame assembly is fixed on the body by stator fixing hole 8.This generator is furnished with electronics tune joint device.Be embedded with 8-16 piece permanent magnet on the non-magnetic fixed piece of the utility model in rotor assembly, correspondingly on the stator core be provided with 8-16 magnetic pole, wherein relative two magnetic poles do not install coil, give over to the fixing hole position, all the other magnetic poles install coil and are cascaded, one end ground connection, the other end and electronic controller input join.
The electronic controller that the utility model is connected with generator is to adopt to have the parallel electrical adjustment module that zero current blocks, and is provided with lockout circuit, adopts miniature current sensor 11, triggers thyristor 9 by control, constitutes electronic control circuit.Thereby adjuster is not worked when making generator unloaded by day.
Electronic control circuit of the present utility model is made up of four parts.Promptly trigger thyristor 9, diode 10, the unloaded lockout circuit on daytime that miniature current sensor 11 constitutes by control; By resistance 12, electric capacity 13, the comparison delay circuit that voltage-stabiliser tube 15 and resistance 16 constitute; By transistor 14, the control signal amplifying circuit that resistance 17 constitutes; By adjusting the power adjusting circuit that thyristor 18 constitutes.
Owing to adopted abovementioned technology, the utility model compared with the prior art, advantage is as follows:
1, because number of magnetic poles increases, the magnetic effective rate of utilization is improved.
2, during generator low speed, illuminating lamp has the better illumination effect, and during high engine speeds, electronic controller plays pressure stabilization function, guarantees the basicly stable of generator output voltage.Therefore prolong illuminating lamp useful life, guarantee safety work.
3, the utility model and installation dimension of the prior art are constant, are convenient to change and supporting use.
In order to further specify characteristics of the present utility model, the embodiment below in conjunction with shown in the accompanying drawing 1 to 2 is described in detail.
Fig. 1 fly-wheel type permanent magnet constant voltage generator structural representation
Fig. 2 fly-wheel type permanent magnet constant voltage generator electronic controller control circuit figure
Among the figure: 1 rotor mount hole, 2 rotor cases, 3 non-magnetic fixed pieces, 4 permanent magnets, 5 stator cores, 6 coils, 7 stator core supports, 8 stator fixing holes 9 trigger thyristor 10 diodes 11 miniature current sensor 12.16.17 resistance 13 capacitors 14 transistors 15 voltage-stabiliser tubes 18 and adjust thyristor
The utility model structure as shown in Figure 1, field frame assembly is fixed on the body through stator fixing hole 8, rotor assembly is installed on the diesel engine flywheel through rotor mount hole, flywheel drives the rotor assembly rotation during work, permanent magnet provides magnetic field energy, produce electric energy in stator coil, the non-magnetic fixed piece plays fixation, by its inclined-plane permanent magnets adjacent is pressed on the rotor case.Stator core is provided with 8--16 magnetic pole, and wherein two relative magnetic poles do not install coil, and all the other magnetic poles install coil and are cascaded, an end ground connection, and the other end and electronic controller input join.The electronic controller operation principle as shown in Figure 2, trigger thyristor 9 and play the blockade effect, when daytime during situation the agricultural vehicle illuminating lamp do not work, no current passes through in the lead, then micro-transformer of current 11 no signals output, triggering thyristor 9 can not triggering and conducting, transistor 14 not conductings, whole electronic controller is not worked, thereby can prolong the life-span of electronic controller.When night, situation had electric current to pass through, micro-transformer of current 11 produced voltage signal, and this signal makes and triggers thyristor 9 triggering and conducting, thereby therefore transistor 14 and 18 conductings of adjustment crystal brake tube play pressure stabilization function.The utility model is owing to increased number of magnetic poles, output voltage is improved than original technology, when low engine speed, illuminating lamp has enough brightness, when high engine speeds, electronic controller plays pressure stabilization function, guarantees output voltage stabilization, make lighting brightness not because of engine speed change changes, thereby guarantee that night work has good illuminating effect.
