Description
Technical field
The utility model is related to a kind of electric motor ventilating device, more particularly to a kind of inside and outside mixed ventilation of variable-frequency motor to fill
Put.
Background technology
Forced air cooling is frequently utilized on variable-frequency motor, is a kind of Major Cooling Methods in variable-frequency motor, has been obtained extensively
Application.Force blower fan as the wind regime in inside and outside air channel, external air channel is flowed out by motor non-shaft stretching end, by support leaf
Piece takes away heat to radiate, and motor heat is taken away in internal air channel by rotor ventilation road, because external air channel point walks most of wind
Amount, internal air channel is larger due to resistance ratios, and the path that cold wind is walked is more long, so as to cause cooling effect of motor uneven, usually
Show as non-shaft stretching end motor bearings, iron core, winding temperature rise relatively low, and axle stretch end motor bearings, iron core, winding temperature rise are higher,
It is unfavorable for the stable operation of motor.
Utility model content
The purpose of this utility model is directed to the deficiency of prior art presence, there is provided mixed ventilation inside and outside a kind of variable-frequency motor
Device.Rationally, motor radiating is uniform, quick, good cooling results for the air channel structure.
To achieve the above object, the utility model provides following technical scheme：
A kind of inside and outside mixed ventilation device of variable-frequency motor, including motor cover, machine shaft, external air channel device are internal
Air-duct apparatus, the machine shaft is passed through in motor cover, and the external air channel device includes strong air-cooler, motor body support leaf
Piece, in motor cover, the strong air-cooler is interior located at motor cover and is fixed on machine shaft for the motor body support blade
One end, the internal air-duct apparatus include strong air-cooler, rear end cap, rotor ventilation road, ventilating duct, internal fan, drive end bearing bracket, institute
State drive end bearing bracket, rear end cap to be located at the front and rear end of motor cover respectively and be individually fixed on machine shaft, on the machine shaft
Internal fan, ventilating duct, rotor ventilation road are sequentially provided with, the internal fan faces ventilating duct, the ventilating duct and rotor ventilation
Road is connected.
It is preferable over the ventilating duct and is highly more than rotor ventilation road.
The motor body support blade is preferable over for louvered.
The inside and outside mixed ventilation device of the utility model kind variable-frequency motor is provided with internal air-duct apparatus and external air channel device,
Mixed ventilation is rational in infrastructure, and motor radiating is uniform, quick, good cooling results, and local temperature rise is too high to be showed will not to occur motor
As, and can energy saving to a certain extent.
Brief description of the drawings
Fig. 1 is a kind of inside and outside mixed ventilation apparatus structure schematic diagram of variable-frequency motor of the utility model；
In figure：1st, strong air-cooler, 2, motor body support blade, 3, rear end cap, 4, rotor ventilation road, 5, ventilating duct, 6,
Internal fan, 7, drive end bearing bracket, 8, motor cover, 9, machine shaft.
Specific embodiment
Below by embodiment combination accompanying drawing, the utility model is described in further detail.
As shown in figure 1, being fixed on the strong air-cooler 1 of the one end of machine shaft 9 as the cooling wind regime in inside and outside air channel；
External air channel is constituted with motor body support blade 2；Strong air-cooler 1 and rear end cap 3, rotor ventilation road 4, ventilating duct 5, internal fan
6th, drive end bearing bracket 7 constitutes internal air channel.
A kind of inside and outside mixed ventilation device of variable-frequency motor, including motor cover 8, machine shaft 9, external air channel device are interior
Portion's air-duct apparatus, the machine shaft 9 is passed through in motor cover 8, and the external air channel device includes strong air-cooler 1, motor body
Support blade 2, the motor body support blade 2 is that louvered is located in motor cover 8, and the strong air-cooler 1 is located at motor cover 8
One end that is interior and being fixed on machine shaft 9, the internal air-duct apparatus include strong air-cooler 1, rear end cap 3, rotor ventilation road 4,
Ventilating duct 5, internal fan 6, drive end bearing bracket 7, the drive end bearing bracket 7, rear end cap 3 are respectively positioned at the front and rear end of motor cover 8 and solid respectively
Due on machine shaft 9, being sequentially provided with internal fan 6, ventilating duct 5, rotor ventilation road 4, the internal fan on the machine shaft 9
6 face ventilating duct 5, and the ventilating duct 5 is connected with rotor ventilation road 4, and the height of ventilating duct 5 is more than rotor ventilation road 4.
The strong air-cooler 1 of the one end of machine shaft 9 is fixed on as the cooling wind regime and motor body in inside and outside air channel
Support blade 2 constitutes external air channel；Strong air-cooler 1 and rear end cap 3, rotor ventilation road 4, ventilating duct 5, internal fan 6, drive end bearing bracket 7
Internal air channel is constituted, the utility model can obviously improve the cooling effect of motor, and internal air channel of the present utility model increased one
Individual internal fan 6 and ventilating duct 5, improve the problem of windage, accelerate the flowing velocity of internal air quantity, and radiating effect is obvious.
The motor produced using the utility model scheme is compared by experiment, can make same electricity than traditional air channel structure
Machine temperature rise declines 10K or so, and this is meant that under identical temperature increase requirement, and motor can shorten iron core, saving copper.It is simultaneously electric
Machine radiating is uniform, non-shaft stretching end motor bearings, iron core, the winding temperature rise occurred without traditional air chute preferably, and axle stretch end motor
Bearing, iron core, winding temperature rise phenomenon higher, can effectively ensure that the reliable and stable operation of motor.
