Abstract

The utility model relates to a small electric generator, particularly a double current generator for motor vehicles. The utility model mainly has the structure that a plurality of identical ferrites equally spaced which are arranged in a rotor are distributed along the circumference; magnetic blocks which are arranged in a stator are opposite to a part of the ferrites of the rotor; the periphery of a silicon steel sheet group is wound with enameled coils. Thus, compared with an ordinary motor with the same size, the utility model has the advantages that the utility model produces large power; the manufacture and the assembly are simple; silicon steel sheet material is saved; the cost is reduced.

Description

The generator of end face relative motion

The utility model relates to a kind of small generator, especially refers to the double current generator that uses on the motor vehicle.

At present, be used to the small-sized alternating current generator that throws light on the motor vehicle, because limited space, generator can not be excessive, when car is in low speed driving, often this small generator electricity shortage, more powerful bulb light dies down on the car to cause, simultaneously, the stator core of this alternating current generator is to build up with the garden ring silicon steel sheet that disk is gone out trough of belt, coil also will be directly around on the silicon steel sheet group, and processing and assembling are complicated, but also waste a large amount of silicon steel sheet materials.

In view of this, the purpose of this utility model provides the double current generator that a kind of stator of end face relative motion and rotor constitute, and as long as the iron core of stator is superimposed with the fritter silicon steel sheet, and coil is placed between silicon steel sheet after winding separately.

The purpose of this utility model is achieved in that it mainly is to be provided with along the identical ferrite of garden phase several piece uniformly at intervals in rotor, be provided with the magnetic block of the part ferrite end face opposite face of rotor in the stator and be wound with enameled wire loop around this magnetic block.

Above-mentioned ferrite end section is the fan annular.

Above-mentioned magnetic block is silicon steel sheet group or the whole silicon steel piece that is overlapped into trapezoidal end section shape by the rectangle silicon steel sheet of different sizes.

Because adopt such scheme: compare with the common generator of same outer diameter as size, the power of generation is big, and manufacturing expense is low saves silicon steel sheet material again, and therefore, cost reduces greatly.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments structural representation.

Fig. 2 the utility model exemplary embodiments rotor local end view.

Fig. 3 the utility model exemplary embodiments stator partial side view.

Among the figure: 1, rotor 11, housing 12, ferrite 2, stator

21, the flywheel of housing 22, magnetic block 23, enameled wire loop 3, diesel engine

4, the casing of diesel engine

Rotor 1 is to stick with glue to connect that uniform one side exposes and several piece ferrite 12 separately (is combined into magnetic core along garden Zhou Junbu 6-20 piece in the annular groove of the circular shell 11 with end face annular groove and inward flange, the end face of this ferrite 12 is fan ring surfaces, this rotor is that the inward flange with circular shell 11 is connected on flywheel 3 sides of diesel engine with screw, as Fig. 1, shown in 2.

The bottom surface of stator 2 in the annular groove of the circular shell 21 with end ring groove connects with screw, magnetic block 22 separately (silicon steel sheet group or silicon steel piece), distribute along garden week, and an exposed lateral side and part ferrite 12 opposite faces and be combined into magnetic core, this magnetic block 22 is to be overlapped into trapezoidal end section by the different big or small rectangle silicon steel sheets of multi-disc, or whole silicon steel piece, in addition, between the annular groove and array magnetic block 22 of circular shell 21, stick with glue enameled wire loop 23 (2～4 winding heads that ground connection placement has wound, tail is drawn two connector lugs after connecting), this stator is to be connected on the casing 4 of diesel engine with circular shell 21 usefulness screws.

Claims
