Description
Technical field
The present invention relates to the cooling mechanism of a kind of motor, more particularly to AC permanent magnet synchronous motor.
Background technology
At present, AC permanent magnet synchronous motor is widely used in every field, the energization work or generation load of motor
Afterwards, it can generate heat.Conventionally, as main shaft need to be equipped with encoder as startup with position feedback after permagnetic synchronous motor
Device, it is impossible to add main shaft fan blade in rear axle as AC induction motor, therefore the radiating of small-power AC permanent magnet synchronous motor is simultaneously
It is undesirable, it have impact on power output.If necessary to strengthen radiating, a fan motor is added outside it, is so both increased greatly
Added volume to need energy consumption again, its radiating effect it is undesirable, all have an impact to the bulk life time of motor.
The content of the invention
In view of the deficiency that background technology is present, the technical problem to be solved in the present invention is to provide one kind by motor radiating effect
The cooling mechanism of the AC permanent magnet synchronous motor of installation that is good and not influenceing encoder apparatus.
Therefore, the present invention adopts the following technical scheme that to realize：A kind of cooling mechanism of AC permanent magnet synchronous motor,
Including motor body part, radiator portion and encoder section, it is characterised in that the housing of the encoder section is provided with upper
Some first guiding gutters provided with air intake, are provided with some second water conservancy diversion of air-out on the housing of the motor body part
Groove, is provided with the division board with ventilating opening in the housing of the encoder section, and the encoder is arranged on the division board,
A chamber is formed between the division board and the housing of the motor body part, fan blade is fixed with the main shaft of motor,
The fan blade is contained in the chamber, and first guiding gutter and the second guiding gutter be arranged in parallel respectively in axial direction.
The section of first guiding gutter is " Z " character form structure.
The housing of the housing of the encoder section, the housing of radiator portion and motor body part is the housing of integral type
Structure.
This cooling mechanism of the present invention, it is simple and compact for structure, it is with low cost, solve AC permanent magnet synchronous motor rear portion
Encoder detector is installed the problem of be unable to the device that installation axle radiates to fan blade, thus substantially increase power output grade and
Overall operation efficiency and overall operation life-span.
Brief description of the drawings
The relevant details of the present invention is further described in conjunction with accompanying drawing below；
The structural diagrams of Fig. 1 present invention are intended to；
Fig. 2 Fig. 1 of the present invention is along A-A sectional views；
In figure, label 5 is control panel for motor.
Embodiment
Referring to the drawings, the cooling mechanism of this AC permanent magnet synchronous motor, including motor body part 2, the and of radiator portion 4
Encoder section 6, the housing of the encoder section 6 is provided with some first guiding gutters 7 of air intake, in the motor body
The housing of part 2 is provided with some second guiding gutters 3 of air-out, and band ventilation is provided with the housing of the encoder section 6
The division board 10 of mouth 9, the encoder 8 is arranged on the division board 10, the division board 10 and the motor body part 2
Housing between formed a chamber 11, fan blade 12 is fixed with the main shaft 1 of motor, the fan blade 12 is contained in the chamber
In 11, the guiding gutter 3 of the first guiding gutter 7 and second be arranged in parallel respectively in axial direction.Wherein, the shell of the encoder section 6
Body and the shell structure that the housing of motor body part 2 and radiator portion is integral type, are easy to being integrally machined for housing.In order to
Prevent large particulate matter from entering the first guiding gutter 7, thus, the section of the first guiding gutter 7 is arranged to the air intake of " Z " font structure
Mouthful.In the present embodiment, its division board 10 had both played the guide functions of axial wind direction, and the support installed as encoder 8 so that
Its structure is compacter.During motor operation, because fan blade 12 is arranged on electric machine main shaft 1, just and then rotate, fan blade 12 is in chamber
11 produce from the middle air-flow for sucking and being discharged to surrounding, and air enters from the first guiding gutter 7, from the ventilating opening 9 on division board 10
Into chamber 11, acted on by the centrifugal flow guiding of fan blade 12 in chamber 11, air-flow is through being axially formed in parallel with motor radiating muscle
Air-flow, is discharged from the second guiding gutter 3, farthest improves the area that air-flow flows through radiator.
