Description
Technical field
The utility model relates to a kind of structure of motor, more precisely, relates to a kind of radiator structure of high-speed electric expreess locomotive, and being applicable to negative pressure device generator etc. needs high-revolving driving field.
Background technology
Depression generator is driven by motor usually, and its rotating speed is more than 2000 revs/min.Can be there is a lot of problem in the motor of high speed rotating, such as efficiency is not high, rotation is steady, moment of torsion is little, and make the vibration of motor rotation large, noise is high.
The heat dissipation problem of motor annoyings people always, the heat radiation of motor in prior art, generally all adopts and arrange radiating ribs on casing, increase the area of dissipation of motor, but the efficiency of this radiator structure is extremely low.Also there is a kind of cooling mechanism in prior art, namely at motor internal provided with fan, this cooling mechanism needs motor internal is in communication with the outside, so that heat radiation, although program radiating effect is relatively good, dust easily enters into motor internal, thus affects the useful life of motor.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of outer radiator structure of high-speed electric expreess locomotive.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of outer radiator structure of high-speed electric expreess locomotive, comprise the motor casing of aluminium alloy extrusions, described motor casing is arranged in body, the termination of described body is provided with the shaft-driven fan of motor, described motor casing is provided with multiple tracks radiating fin outwardly, constitutes the groove for wind circulation between multiple tracks radiating fin.
When high-speed electric expreess locomotive is when working, motor shaft drive fan is rotated, and the high speed rotating of fan makes wind flow out from passage or flow into, thus is taken away by the heat on motor casing, significantly reduces the working temperature of high-speed electric expreess locomotive.Namely dust can not be made to enter into motor casing inside, again can fast, temperature with high efficiency, meanwhile, this radiator structure easy accessibility, with low cost.

Embodiment
The technical problem solved to make the utility model, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further embodiment of the present utility model.
Referring to figs. 1 to Fig. 3, the utility model discloses a kind of high-speed electric expreess locomotive, the rotor comprising stator 1, motor shaft 4 and install on the motor shaft (4), rotor of the present utility model has two, be designated as the first rotor 2 and the second rotor 3 respectively, two rotors share a motor shaft 4, and are assembled by technology known in the field.The first rotor 2 and the second rotor 3 coordinate with two ends of stator 1 respectively; Reference-view direction, the first rotor 2 is assemblied in the left end of stator 1, namely with the left end matched in clearance of stator 1; Second rotor 3 is assemblied in the right-hand member of stator 1, namely with the right-hand end matched in clearance of stator 1.
The first rotor 2 is identical with the structure of the second rotor 3, and for the first rotor 1, conically, the end of described stator 1, also in the taper shape with the first rotor 2 matched in clearance, namely has a conically inner concave 11 to described first stator 2.
High-speed electric expreess locomotive of the present utility model, adopts the structure of two rotors, coordinates respectively with the gap between two ends of stator, and its clearance plane coordinated is coniform, and such structure makes this motor can obtain larger moment of torsion, runs more steady.
Rotor in the utility model, stator can adopt public structure well known in the art, such as rotor comprises iron core 21 and pastes the magnet 22 etc. on iron core 21, also have the winding etc. on stator and stator, all can adopt public material well known in the art.Such as magnet can adopt rare earth permanent-magnetic material, and remanent magnetism is high, coercive force is high, and iron core adopts mild steel to manufacture etc.
The invention also discloses a kind of radiating shell of high-speed electric expreess locomotive, with reference to figure 4, also comprise motor casing 5, stator 1, motor shaft 4, rotor are all arranged in this motor casing 5, described motor casing 5 is arranged in body 6, and this body 6 also can regard a sleeve as, itself and motor casing 5 is fixed together by screw, the termination of described body 6 is provided with the fan 61 of motor shaft 4 driving, and described motor casing 5 is provided with the groove 51 for wind circulation that multiple tracks indent is formed.
When high-speed electric expreess locomotive is when working, motor shaft 4 drive fan 61 is rotated, and the high speed rotating of fan 61 makes wind flow out from passage 51 or flow into, thus is taken away by the heat on motor casing 5, significantly reduces the working temperature of high-speed electric expreess locomotive.Namely dust can not be made to enter into motor casing 5 inner, again can fast, temperature with high efficiency, meanwhile, this radiator structure easy accessibility, with low cost.
In the utility model preferred embodiment, the quantity of described groove 51 is four, lays respectively at the edges and corners of cuboid motor casing 5.
