Description

A kind of New-type electric machine wind path structure
Technical field
The invention belongs to motor technology field, more particularly to a kind of New-type electric machine wind path structure.
Background technology
Motor is the reforming unit for converting electrical energy into mechanical energy, and Three-Phase Asynchronous is led to stator Electricity, stator produces rotating excitation field, the conducting bar cutting magnetic line of rotor, therefore rotor stress, rotor follow the rotating excitation field of stator Direction rotates, and stretches transmission torque eventually through armature spindle, is also achieved that electric energy changes into the process of mechanical energy, motor is normally transported Internal in turning to have stator loss, rotor loss, core loss, mechanical loss, stray loss etc., these are lost in motor internal most All showed eventually in the form of heat.
2 poles and 4 pole synchronous rotational speeds are respectively 3000r/min, 1500r/min, and motor rotary speed is fast, and aerofoil fan is axial Ventilation effect is good, therefore can be used for more air quantity cool down iron core, and wind of some reflection cools down machine winding, internal Ventilation and heat is good, therefore there is no problem for symmetrical aerofoil fan.And 6P and its symmetrical centrifugal fan of the above, with motor pole number Increase, motor speed reducing, and electric motor winding end will be unable to sufficiently be cooled down if also with aerofoil fan at this time, separately The increase of outer number of poles, number of stator slots will certainly will increase, and cause end turn gap very little, the wind of end turn substantially not from coil with The gap mistake of coil, and pass through from the straight line portion of motor.Also there is the phenomenon that tacks in the muscle of centrifugal fan and welding axis, weld muscle axis phase When in a small fan, it, which is acted on, is divulged information to rotor core, and iron core air quantity is often stranded with how winding overhang air quantity is distributed A difficult point of design is disturbed, therefore there are problem for symmetrical centrifugal fan.
The content of the invention
The purpose of the present invention is the bad situation of the cooling effect for above-mentioned machine winding and iron core, there is provided a kind of new Air channel structure of motor, changes wind path walking path, improves the cooling effect to left and right end winding and iron core.
To solve above technical problem, the technical solution adopted by the present invention is:The New-type electric machine wind path structure, including machine Seat, cooling tube, axial gusset and internal fan, engine base includes machine base body, engine base inner ring, and interannular is in machine base body and engine base Cooling chamber, circumferentially spaced in cooling chamber to be equipped with multiple axial gussets, each axial direction gusset is fixedly installed with engine base, adjacent axis Some cooling tubes are laid with into the cavity between gusset;The axle stretch end side for defining shaft is located at motor left part for a left side, internal fan And be fixed on by fan base in shaft, it is additionally provided with spacer ring, partition plate and fixes and set with axial gusset every air duct, the spacer ring Put and the first spacer ring including being set close to internal fan and the second spacer ring for being laid near right end cap;The partition plate is fixed In in shaft and positioned at the left part of rotor axial ventilating duct;It is described to be fixed and including axially disposed every air duct and axial gusset And it is sheathed on first every air duct and being disposed radially and be fixed on first the second wind isolation board on the right side of air duct on the outside of stator; With being equipped with annular wind shield at the corresponding position of the first spacer ring on the right side of the internal fan, wind shield is fixed with internal fan Connect and rotated with internal fan.
When internal fan rotates, air-flow outwards reaches cooling chamber by internal fan and under the stop of wind shield, then One divulges information every the winding and shaft that right part is sent under the stop of air duct and the second wind isolation board, afterwards air-flow through rotor axial Road conveys to the left, and under the stop of partition plate through stator radial ducts by stator core, finally first every air duct and Under the stop of second wind isolation board internal fan is back to by the winding of left part.
The vertical distance of the wind shield and the first spacer ring is 5 ~ 10mm.
The outside of the right end cap is additionally provided with fan housing, and external fan is equipped with fan housing.
Described to be welded and fixed every air duct and axial gusset, the spacer ring is also welded and fixed with axial gusset.
The axial direction gusset is evenly distributed arrangement and is equipped with 10.
The beneficial effects of the invention are as follows:The New-type electric machine wind path structure, by circumferentially disposed vertically first every air duct Be vertically arranged to first the second wind isolation board on the right side of air duct, and the setting of partition plate and wind shield, make wind path along regulation road Line is walked, and abundant ventilating and cooling can be carried out to the winding of stator core and left and right ends motor, improve to winding and The cooling effect of iron core.
