Abstract

The utility model relates to a low-speed AC generator for vehicles. The internal diameter of a stator of an existing AC generator is enlarged, the shape of a stator groove is changed to a trapezoid from an original pear shape, the stator winding is increased, the cross-sectional shape of the pole claw of a rotor is changed to a trapezoid from an original quadrangle and the edges of the trapezoid are chamfered, the wire diameter of a magnetic field coil is enlarged, the number of the turns of the magnetic field coil is reduced to achieve the purpose of power generation with low speed. The low-speed AC generator for vehicles has the advantages of simple and reasonable structure, good power generation with low speed performance, good compatibility and reasonable parameters for high speed and low speed operation, and is suitable for urban buses. The low-speed AC generator for vehicles can efficiently reduce the consumption of storage batteries, and is used as a power generation device for motor vehicles with low speed.

Description

A kind of low speed AC generator for vehicle
The utility model relates to a kind of alternating current generator, and refering in particular to is a kind of low speed AC generator for vehicle.
Alternating current generator as the main electric supply installation on the automobile, obtained general employing, its technical performance has also obtained continuous raising, but, the alternating current generator that is fit to urban public transport automobile handling characteristics is not but seen, because the urban public transport car is subjected to the restriction of travel speed and operating range, need usually starting, stop, therefore, a large amount of starting currents causes automobile storage battery to be in the power shortage state for a long time, makes accumulator pole fragile, in addition the urban traffic congestion, bus is in the low cruise situation for a long time, existing automobile current generator can't produce electric energy at lower-speed state, and the electric energy of storage battery consumption can in time not replenished, and causes storage battery to be in the power shortage state for a long time and damages, during the automobile night running, also dare not use illuminating lamp, influence travel safety, according to the public transport department statistics, city bus battery damage situation is quite serious, causes enormous economic loss for public transport department.
The purpose of this utility model is to overcome the deficiency of prior art and a kind of rational in infrastructure, stable performance is provided, and the low speed power generation performance is good, the low speed AC generator for vehicle that interchangeability is good.
The utility model is to adopt following proposal to realize: the diameter of stator bore that will have alternating current generator now increases, stator slot shape changes into trapezoidal by original pyriform, stator winding is increased, to improve stator magnetic circuit, to reduce the generating rotating speed, simultaneously, rotor pole pawl section configuration is changed into by original square trapezoidal, and with edge chamfer, to increase the sectional area of yoke, reduce leakage field, improve magnetic circuit, the line with field coil directly strengthens in addition, and the number of turn reduces, reduce field resistance, improve magnetic field intensity, increase excitatory number of ampere turns, reduce the generating rotating speed.Thereby reach the purpose of low speed generating.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model parts field frame assembly structural representation;
Accompanying drawing 3 is the utility model stator slot structural representation;
Accompanying drawing 4 is the utility model claw-pole structure schematic diagram.
See accompanying drawing 1,2,3,4, the utility model is by field frame assembly (1), rotor assembly (2), brush cover assembly (3), drive end cap assembly (4), rectifier assembly (5), brushgear assembly (6) is formed, the installation form of each part mentioned above and existing alternating current generator are just the same, its improvement is that diameter of stator bore is φ 96.5~98.5mm, and stator slot (8) is trapezoidal, and the pawl utmost point (9) cross section is trapezoidal and edge chamfer, the stator winding line directly is φ 1-φ 1.5mm, every groove lead 12-20 circle, the rotor coil line directly is φ 0.5-φ 0.9mm, the number of turn is the 300-500 circle.
Operation principle of the present utility model is sketched in following: because of increasing diameter of stator bore, changing the stator slot shape is trapezoidal by pyriform, thereby reduced yoke portion (7) size, stator magnetic circuit is fully utilized, simultaneously, stator winding is increased to present 12-20 circle by 10 original circles, has further improved stator magnetic circuit, reduced the generating rotating speed; In addition, the rotor claw utmost point (9) cross section is changed into by square trapezoidal, and at edge chamfer, increase the area of yoke (10), reduced leakage field, improved magnetic circuit, strengthen the magnetic field effect, increased the line footpath of field coil simultaneously, reduced the number of turn, reduced field resistance, thereby improved field supply, increased excitatory number of ampere turns, the electric power generation rotating speed is further reduced, reach the purpose of low speed generating, to adapt to the operation characteristic of city bus.
In sum, the utility model is simple and reasonable, the low speed power generation performance is good, interchangeability is good, the high, low speed operational factor is reasonable, is suitable for industrialized production, is fit to the city bus operation characteristic, can reduce the consumption of storage battery effectively, be suitable for using and on the motor vehicle of low cruise, make generating equipment usefulness.
