Abstract
The utility model relates to an inner-cooling alternator, including the shell, the stator fixed on the shell, and the rotor positioned on the shell through the guide spindle, the both sides of the axial direction of which are fixed with the fan blades. The two fan blades are installed in the gap between the two terminals of guide spindle and the shell, wind cooling the stator and the rotor directly. The utility model has the advantages of a rational structure design, maintaining the structure of the generator, increasing the air flow which can traverse the two terminals of the stator and the rotor, making the heat dissipation more uniform, and guaranteeing the stability of the output power for a long term.
Description
Technical field:
The utility model belongs to dynamo-electric field, and particularly a kind of inner-cooled produces alternating current generator.
Background technology:
The general external-cooling type structure that adopts of existing generator heat radiation also promptly is fixed with fans on the guide shaft outside housing, perhaps is fixed on the belt pulley, is single fan structure.This structural design exists not enough, and the air-flow of fan will pass housing, and has only single-ended air-cooledly, and air quantity is little, can't evenly dispel the heat to motor, makes the power output instability, also influences the life-span of motor.
Summary of the invention:
The purpose of this utility model is the inner-cooled alternating current generator of a kind of built-in fans structure of design.
Technical solutions of the utility model are achieved in that a kind of inner-cooled alternating current generator, comprise housing, be fixed on stator on the housing, be positioned rotor on the housing by guide shaft, and the axial both sides of its middle shell internal rotor are fixed with fans respectively.Utilize the gap of guide shaft two ends and housing that two fans are installed, directly air-cooled at stator, rotor.
Described fans direct spot welding is fixed on rotor claw and extremely goes up, and it is little to take up room.
The utlity model has reasonable in design, do not change electric generator structure, increase wind flow, air-flow can traverse the stator and rotor two ends, makes heat radiation more even, the stability of the power output that guarantees to work long hours.
Description of drawings:
Below in conjunction with concrete legend the utility model is described further:
Accompanying drawing alternating current generator profile
Wherein
1-housing 2-stator 3-rotor
4-guide shaft 5-belt pulley 6-fans
Embodiment:
With reference to accompanying drawing, a kind of inner-cooled alternating current generator, comprise housing 1, be fixed on stator 2 on the housing 1, be positioned rotor 3 on the housing 1 by guide shaft 4, guide shaft 4 extends to outside the housing 1, and is fixed with belt pulley 5 on the guide shaft outside housing 4, wherein be fixed with fans 6 respectively in housing 1 internal rotor 3 axial both sides, two fans 6 with equidirectional be good, like this airflow direction one to, can effectively increase flow velocity and flow, satisfy the need of the heat radiation of accessory, guarantee that the generator internal temperature is stable.
In addition, fans 6 can adopt spot welding to be fixed on rotor 3 pawls and extremely go up, and the accessory layout can be compact more in the housing like this, and it is littler that the generator volume can be done, suitable with the small product size of the external fan of tradition.Fans 6 also can be fixed on the guide shaft 4, and is close to rotor 3 pawls and extremely goes up, to save the space.
