Abstract
The invention relates to a motor engine base and especially relates a full-laminated motor engine base with a double-circulation air channel. The engine base comprises several stator laminations, stator end plates, a stator pulling plate and two end stator pressing rings. The stator laminations are laminated into one body and then left and right ends are provided with the stator end plates. An outer side is fixed with the stator pulling plate. Finally, the stator pressing rings are welded so as to form the motor engine base. Each stator lamination is provided with an air channel port. The stator end plates are provided with the air channel ports. The stator pressing rings are provided with axial through holes. Each inner side of an end portion is provided with an air channel gap. The several stator laminations are laminated into one body, and then the air channel ports form several air channels. Some of the air channels, the air channel ports on the stator end plates and the through holes on the stator pressing rings form an outer circulation air channel, and other air channels, the air channel ports on the stator end plates and the air channel gaps on the stator pressing rings form an inner circulation air channel. By using the engine base of the invention, a problem that an air channel structure of an existing motor engine base is connected to an internal portion of the motor so that cooling air pollutes internal components is solved.
Description
Technical field
The present invention relates to electric machine stand, a kind of full-laminated motor support carrying Two-way Cycle air channel.
Background technology
At present, when design of electrical motor, cause motor overheating, generally for the heat produced during preventing motor continuous service
Air channel can be set in electric machine stand structure.Cooling wind, from air channel process, can take away the heat that motor produces, and plays heat radiation fall
The effect of temperature.General in order to strengthen cooling effect, air channel all can connect motor internal, and cooling wind can be brushed by air channel and turn
Son and the surface of coil, produce good cooling effect.The air channel structure of current most of electric machine stand is all from outside motor
It is communicated to motor internal, then by motor internal to outside motor, forms a circulation wind path.It is substantial amounts of owing to cooling wind containing
The impurity such as steam, sand and dust, cooling wind can be polluted internal part to motor internal, be caused heat radiation variation, acceleration insulation system old
The adverse consequencess such as change, rotary part abrasion.
Summary of the invention
The present invention is to solve that the air channel structure of existing electric machine stand connects with motor internal and causes cooling wind to pollute
The problem of internal part, it is provided that carry the full-laminated motor support in Two-way Cycle air channel.
The present invention adopts the following technical scheme that realization: carry the full-laminated motor support in Two-way Cycle air channel, including
Some stator lasminations, stator end plate, stator arm-tie and two ends stator pressing ring, stator lasmination laminate integral after set at two ends, left and right
Putting stator end plate and stator pressing ring, stator arm-tie is overlapped on stator lasmination, stator end plate and stator pressing ring, at impaction state
Under, weld around stator arm-tie border, form electric machine stand.Have wind passage mouth on each stator lasmination, stator end plate is also opened
Having wind passage mouth, stator pressing ring has axial through hole, its tip inside also has air channel breach, and some stator lasminations laminate into
After Yi Ti, wind passage mouth forms some air channels, some of them air channel and the wind passage mouth on stator end plate, through hole shape on stator pressing ring
Outer circulating air duct, outer circulating air duct and end cap air inlet, air outlet is become to be formed on outer circulation wind path, remaining air channel and stator end plate
Wind passage mouth, air channel breach on stator pressing ring formed in interior circulation air path, interior circulation air path and rotor axial air vent formed
Portion's closed circuit, interior circulation air path and outer circulating air duct be made up of air channel breach and through hole respectively, i.e. the wind path of the two is different, and two
Person does not connects.
In electric machine stand, arrange Two-way Cycle air channel, inside and outside, interior circulation air path and rotor axial air vent form inside and follow
Loop back path, is responsible for the heat exchange of motor internal, makes motor internal heat balance, it is to avoid the phenomenon of hot-spot, and by motor
The internal heat produced delivers to support；Outer circulating air duct and end cap air inlet, air outlet form outer circulation wind path, are responsible for motor machine
Seat and the exchange of outside heat, deliver to outside motor environment by the heat on support.Two-way Cycle air channel, inside and outside is arranged at machine
On seat and mutually isolated, so by with the coordinating of electric motor end cap, motor internal space can be made to completely enclose, outer circulation wind
The cooling wind on road can not enter motor internal, causes damage thus without internal volume；The air of interior circulation wind path circulates also
Will not leak.
