Description
Technical field
The utility model relates to machine field, particularly a kind of wind path structure that is applied in the motor.
Background technology
Along with the extensive use of industrial motor in varying environment, the heat dissipation problem of motor more and more receives people's concern.Temperature rise is the temperature difference between motor self temperature and the ambient temperature, be that motor generates heat in running and causes that the reason that the motor feels hot mainly contains: operating electric machine iron core is in and can produces the stray loss that can produce copper loss after iron loss, the winding energising, also have other etc. in the magnetic field of alternation and can cause that all the temperature of motor raises.When the heating of motor and heat radiation reached poised state, temperature rise remained on the stable level, and motor can work.
Be used at present the wind path structure of motor radiating in the asynchronous motor, mainly comprise by rotor core, rotor fan blade, deep bead, stator core, stator winding, support, front end housing, rear end cap form sealing interior wind path and by rear end cap, fan housing and be arranged on rear end cap and fan housing between the outer ventilation circuit that forms of fan, its structure is as shown in Figure 1.
Wherein, the power source of the interior wind path wind regime that to be motor internal formed by the deep bead 3 of the rotor fan blade 4 of rotation and with it applying, the interior transportation work style that flows is at first brushed motor front end of line bag, then oppositely be blown into the line bag of motor rear end through the support axial ducts 8 that formed by support 2 and stator core 5, under the stopping of rear end cap 10, return, finish circulation through rotor axial air channel 7.In the process of interior transportation work style circulation, the heat that electric machine iron core and line bag coil produce is taken away, be delivered on support 2, front end housing 1 and the rear end cap 10; Also by radiation and heat exchange pattern heat is passed on support, front end housing and the rear end cap of motor as the iron core of thermal source and the heat of coil generation simultaneously.The power source of outer ventilation circuit provides for the external fan of non-shaft stretching end, outer transportation work style enters the fan housing inner chamber by the wind hole on the motor fan housing 9, under the effect of fan 11, the from outside wind of cooling usefulness is delivered on the radiating ribs of support crust, realized distributing the motor body heat by the radiating ribs of cooling off support.
This kind wind path structure forms the interior wind path structure of a sealing because interior transportation work style circulates all the time in support, the temperature of motor can be more and more higher, just simply cools off support by outer transportation work style, can not realize the demand to motor radiating.When the temperature rise of support accumulation is larger, will inevitably cause damage to motor.
The utility model content
The utility model technical issues that need to address provide a kind of wind path structure that can effectively reduce electric machine temperature rise, to guarantee the safe and stable operation of motor.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows.
Air channel structure of motor, comprise by motor internal by the cavity between front end housing and the iron core, support axial ducts between support and the iron core, the interior wind path that cavity and rotor axial air channel form between iron core and the rear end cap and by the fan housing with the wind hole, the outer ventilation circuit that fan and support crust radiating ribs form, be provided with on the flabellum of described fan for the cooling air that external fan is sent into and blow respectively fan dividing plate to interior wind path and outer ventilation circuit, the flabellum position that the inside wind path of the corresponding fan of described rear end cap blows cooling air is provided with air inlet, and the position of wind path is provided with the exhaust vent of sending cooling air in the described front end housing correspondence.
Because the technological progress of having adopted technique scheme, the utility model to obtain is as follows.
The utility model is on the basis of existing common closed wind path structure, by improving the structure of front end housing, rear end cap and fan, so that interior wind path structure is improved to open type by closed type, adopt same external fan to provide simultaneously power source for wind path in the motor and outer ventilation circuit, make extraneous cold air directly cool off line bag, stator core and rotor core, improve the radiating effect of motor, can effectively reduce electric machine temperature rise, guaranteed the safe and stable operation of motor.
