Description

Motor

Technical field

The present invention relates to a kind of motor, more particularly to a kind of motor with active heat removal function.

Background technique

Refering to fig. 1, general motor 1 includes shell 11, the stator 12 being fixedly installed in the shell 11, and can edge Own axes are rotatably provided in the rotor 13 surrounded in the shell 11 and by the stator 12.The rotor 13 can be by magnetic force It influences and is rotated relative to the stator 12, to generate power to drive other structures or component.Due to 13 phase of rotor For can both generate high fever when the stator 12 rotation, therefore multiple ventilation holes 111 are opened up on the shell 11, so that Air-flow is got enter into the shell 11, with the cooling stator 12 and the rotor 13, however the ventilation hole of the motor 1 111 are only capable of lacking the function of active heat removal passively into that could generate heat loss through convection by external air flow.In addition, above-mentioned Shell 11 is made of to adopt full slice system design and with metal, and inner surface is towards the rotor 13, since conductor is changing Eddy current can be generated in magnetic field, therefore the inner surface of shell 11 made of aforementioned metal can constantly be changed by the magnetic field of the rotor 13 The influence of change and influence electricity, to generate eddy current on the shell 11, excessive eddy current will lead to overheat and resistance The situation that the stagnant rotor 13 rotates.

Summary of the invention

The purpose of the present invention is to provide it is a kind of have the function of active heat removal and can avoid shell generate eddy current it is electronic Machine.

Motor of the invention include bottom shell body with multiple wind guide tanks for extending to bottom surface by top surface, be set to it is described The cap for the pivot spaces for being connected to the wind guide tank is defined on bottom shell body and jointly with the bottom shell body, is rotationally arranged at The pivot spaces are interior and are located at the rotor of the top of the wind guide tank, are set in the pivot spaces and around the rotor Stator, and be covered on the bottom shell body and cover the clamshell of the cap, the rotor has multiple to be passed through downwards by top surface It wears to the aperture of bottom surface.

Preferably, aforementioned motor, wherein the clamshell has the engaging portion being incorporated on the bottom shell body, is located on institute The outer ring wall portion of at least one port is stated on engaging portion and formed, and is connected to the top wall portion of the outer ring wall portion apical margin.

Preferably, aforementioned motor, wherein the bottom shell body has the bottom wall part for forming the wind guide tank, and described in connection Bottom wall part and around the stator surround wall portion.

Preferably, aforementioned motor, wherein the cap be with copper at and top surface patch touch the inner wall of the clamshell.

Beneficial effect of the invention is: multiple apertures are offered on the rotor, therefore when the rotor is relative to institute When stating stator rotation, the air in the aperture can be forced to flow because of rotation, to generate active inspiration effect, so may be used Air-flow is introduced by the wind guide tank, and is drawn up the air of lower section through the aperture, then down through described fixed Gap on son is finally sent out by the wind guide tank again, can so form active heat loss through convection, improving heat radiation efficiency.Again Person, the wind guide tank are the lower sections for being set to the rotor, therefore can reduce what the bottom shell body was influenced by the rotor field Area, and the bottom shell body by the wind guide tank cutting and incomplete plane, induced current are not easy to generate thereon, therefore can Avoid the generation of eddy current.

Specific embodiment

The following describes the present invention in detail with reference to the accompanying drawings and embodiments.

Refering to Fig. 2, Fig. 3 and Fig. 4, one embodiment of motor 2 of the present invention includes bottom shell body 21, one settings In on the bottom shell body 21 and with the bottom shell body 21 define jointly cap 22, one of a pivot spaces 220 it is rotatable Be set in the pivot spaces 220 rotor 23, one of ground are set in the pivot spaces 220 and around the rotor 23 Stator 24 and a clamshell 25 for being covered on the bottom shell body 21 and covering the cap 22.

Refering to Fig. 2, Fig. 4 and Fig. 5, it should be strongly noted that the aspect of the cap 22 for ease of description, therefore The clamshell 25 is omitted in Fig. 5.The bottom shell body 21 has the bottom wall part of carrying rotor 23 and the stator 24 211 and connection 211 outer peripheral edge of bottom wall part and surround wall portion 212 around the stator 24.The bottom wall part 211 With multiple wind guide tanks 213 for extending to bottom surface and the connection pivot spaces 220 by top surface.The cap 22 is in addition to offering Other than the hole 221 worn for the rotor 23, the rotor 23 and the stator 24 are not exclusively also blocked as illustrated in fig. 5, Therefore the pivot spaces 220 will not be closed, the top surface patch of the cap 22 touches the inner wall of the clamshell 25, and the cap 22 It is not complete round and there is notch, and the cap 22 be with copper at and can be used to be electrically connected and several be set to notch The electronic building brick 3 at place, the electronic building brick 3 generated heat when operating can pass through contact conduction pattern for heat and reaches the shell The effect of on lid 22 to reach heat dissipation.The rotor 23 have it is several by top surface downward through to bottom surface and each other in angularly ring The aperture 231 of shape arrangement.There is the clamshell 25 one pushing up around wall portion 212 for the bottom shell body 21 is incorporated into a manner of locking and set The engaging portion 251, one of edge is located on the engaging portion 251 and in the outer ring wall portion for forming two ports 252 on outer peripheral surface 253 and one be connected to 253 apical margin of outer ring wall portion and the top with about 211 bottom wall part of the bottom shell body 21 separately Wall portion 254.The port 252 is the electronic building brick 3 entered for conducting wire to be electrically connected on the cap 22.

Refering to Fig. 2, Fig. 5 and Fig. 6, when the rotor 23 is rotated relative to the stator 24, in the aperture 231 Air can be flowed because of rotation, in addition the wind guide tank 213 in the connection external world is set at lower section, so that the air in the external world It can be driven and be entered in the pivot spaces 220 by the wind guide tank 213, and institute is flowed upwardly toward by the aperture 231 Cap 22 is stated, the gap on the stator 24 can be passed downwardly through then along the air of 22 bottom surface of cap flowing, finally again It is secondary that the external world is flow to by the wind guide tank 213 of bottom, reach and is actively drawn the effect of air-flow is to generate heat loss through convection.Due to described Cap 22 is with copper at therefore can pass through bottom surface and absorb heat in the moving air that is in contact with it, also can pass through contact conduction The heat on the electronic building brick 3, and the inner wall of the top wall portion 254 through the top surface patch touching clamshell 25 are absorbed, heat is passed It leads on the clamshell 25, making thermal energy dissipate to the external world by the clamshell 25, enhances heat dissipation effect.

In addition, the wind guide tank 213 is the underface positioned at the rotor 23, thus the top surface of the bottom wall part 211 with The contact area in the magnetic field that the rotor 23 generates is smaller, in addition the wind guide tank 213 makes the bottom wall part 211 not be one complete Whole plane, induced current are not easy to generate thereon, to can avoid the generation of eddy current, ask to avoid fever and other correlations Topic.

In conclusion air-flow can be introduced from the external world to described turn when the rotor 23 is rotated relative to the stator 24 Son 23 and the stator 24 carry out active heat dissipation, and the design of the wind guide tank 213 can avoid the bottom shell body 21 and generate whirlpool Electric current, therefore the purpose of the present invention can be reached really.
