Abstract
The utility model discloses an air channel structure a motor. The air channel structure includes an air channel from an air inlet arranged in a motor structural member to an air gap between a stator and a rotor. The motor structural member is disposed on one end of an engine base and is in a hollow structure provided with the inner air channel. A plurality of air outlets are arranged in the motor structural member and in the position of the air gas between the stator and the rotor. In the utility model, by arranging part of the air channel in the motor structural member and arranging the air outlets in the motor structural member and in the position of the air gas between the stator and the rotor, cooling air can act on a heating unit directly and uniformly. Thus, turbulent flows of inner effective air are eliminated, and the cooling effect of a generator winding is improved to the highest degree. And problems of large turbulent flows of an inner channel, non-uniform cooling performance and poor cooling effect of a low-speed high-capacity motor are solved. The air channel structure of the motor has advantages of uniform cooling performance and good cooling effect, and is especially suitable for a generator or an electromotor having low speed and high capacity.
Description
Technical field
The utility model relates to the air-cooled technology of motor, particularly relates to a kind of motor wind path structure.
Background technology
For the low speed large-size machine, cause heat-sinking capability poor because rotating speed is low, need carry out air-cooled to heat-generating units by external impetus usually; But because the low speed large-size machine is bulky, particularly on diameter dimension, this causes inner wind path turbulent flow big; Cooling air can not be distributed on the heater; Inhomogeneous cooling is even and cooling effect is poor, as shown in Figure 1, and the left side is better than the cooling effect of right-hand part.
The utility model content
The purpose of the utility model provides a kind of motor wind path structure, and the inner wind path turbulent flow of existing low speed large-size machine is big, inhomogeneous cooling is even and the problem of cooling effect difference to solve.
The purpose of the utility model realizes through following technical scheme:
A kind of motor wind path structure; Comprise from being opened in the wind path of air gap between air inlet to stator and the rotor on the electric machine structure spare; Said electric machine structure spare is arranged on an end of support; For inside is provided with the hollow-core construction of wind path, the air gap opposite position is uniformly distributed with and offers some air outlets on it and between stator and rotor.
The monnolithic case of said electric machine structure spare is the wheel of a similar octagon; Comprise the wheel hub of a hollow circular ring shape, eight tabular limits of taking turns of eight hollows that are distributed on the tabular spoke of hollow on the said hub outside surface and said spoke end is linked together; Offer the said air inlet that is communicated with space in extraneous and the wheel hub on the inner surface of said wheel hub; Space in said wheel hub, spoke and the wheel limit communicates, said take turns to be uniformly distributed with on the limit offer some said air outlets.
The beneficial effect of the utility model is: inner through the part wind path being arranged on electric machine structure spare; And the air gap opposite position is uniformly distributed with and offers some air outlets on electric machine structure spare and between stator and rotor; Cooling air is acted on the heat-generating units directly, equably; Eliminate the turbulent flow of inner effective wind, farthest improved the cooling effect of generator windings.

Embodiment
Shown in Fig. 2～3; The motor wind path structure of the utility model; Comprise from being opened in air inlet to stator 2 and the wind path of 3 air gaps of rotor on the electric machine structure spare 1; Said electric machine structure spare 1 is arranged on an end of support 4, for inside is provided with the hollow-core construction of wind path, on it and stator 2 and 3 air gap opposite positions of rotor be uniformly distributed with and offer some air outlets.
Preferably; The monnolithic case of said electric machine structure spare 1 is the wheel of a similar octagon; Comprise the wheel hub 101 of a hollow circular ring shape, eight tabular limits 103 of taking turns of eight hollows that are distributed on the tabular spoke 102 of hollow on said wheel hub 101 outer surfaces and said spoke 102 ends are linked together; Offer the said air inlet that is communicated with space in extraneous and the wheel hub 101 on the inner surface of said wheel hub 101; Spaces in said wheel hub 101, spoke 102 and the wheel limit 103 communicate, said take turns to be uniformly distributed with on the limit 103 offer some said air outlets.
Particularly point out, the described motor of the utility model is generator or motor.
The utility model is mainly used on jumbo generator of low speed or the motor, has the advantage that cooling evenly reaches good cooling results.
