Abstract
The utility model belongs to the air-cooled structure of motor radiating cooling technology field more particularly to a kind of New High-Voltage Motor, including shaft, stator, rotor, rotor field spider, outer ventilation circuit device, interior wind path import, the outlet of interior wind path, internal fan, external fan, baffle.Only internally wind path is studied herein, and tubaeform arcuation baffle fluid flow direction is placed at the rotor field spider of internal wind path and is changed, and centrifugal internal fan is placed in motor left end.The utility model is ingenious in design, the size of gas chamber where on the one hand increasing air inlet through hollow shaft mouth, the vortex phenomenon of gas chamber where improving rotor axial air inlet；On the other hand air gap entrance area structure is optimized, make the entrance section of air gap accumulate along axis direction to successively decrease with certain radian, thus increase air gap inlet area, and then increase the air capacity into air gap, while it is more reasonable also to distribute the air mass flow in air duct.
Description
Technical field
The utility model is related to motor radiating cooling technology field, the air-cooled structure of specially a kind of New High-Voltage Motor.
Background technology
Cooling structure directly affects the distribution in fluid field and temperature field in high-voltage motor.Due to the inside wind path of high-voltage motor
It is the heat not generated when the extraneous enclosed construction being in contact, motor operation to distribute in time, therefore cooling system
It unites extremely important.Currently, the air mass flow of the air inlet and stator's radial air duct of the rotor axial ventilation of most high-voltage motors
Unbalanced, local temperature is excessively high when leading to motor operation.If stator winding temperature is excessively high, it is more than heat-resistant limit, can directly damages
Bad winding；If temperature of rotor is excessively high, the performance of permanent-magnet material can be changed, even result in irreversible demagnetization, directly affect motor
Efficiency, service life and reliability of operation.It is such to solve therefore, it is necessary to design a kind of air-cooled structure of New High-Voltage Motor
Problem.
Utility model content
The purpose of this utility model is to provide a kind of air-cooled structures of New High-Voltage Motor to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions：A kind of air-cooled structure of New High-Voltage Motor,
Including shaft, stator, rotor, rotor field spider, outer ventilation circuit device, interior wind path import, the outlet of interior wind path, internal fan, external fan, gear
Plate.It is characterized in that：It places baffle fluid flow direction at the rotor field spider of internal wind path to be changed, on a motor left side
Place centrifugal internal fan in end.
Further, the baffle flare arcuation.
Further, a length of L of the arc of the baffle, thenWherein l=kbh；h
For winding overhang length；kbIt is determined by assembly technology；kaIt is determined by processing technology, d is width of air gap.
Compared with prior art, the utility model has the beneficial effects that：The air-cooled structure of this kind of New High-Voltage Motor solves
The excessively high problem of local temperature caused by air duct air mass flow is unbalanced inside high-voltage motor.On the one hand air inlet through hollow shaft is increased
The size of gas chamber where mouthful, the vortex phenomenon of gas chamber where improving rotor axial air inlet；On the other hand to air gap inlet region
Domain structure optimizes, and so that the entrance section of air gap is accumulated and is successively decreased with certain radian along axis direction, thus increases air gap and enter
Open area, and then increase the air capacity into air gap, while it is more reasonable also to distribute the air mass flow in air duct.
Description of the drawings
Fig. 1 is one of partial structural diagram of the utility model；
Fig. 2 is one of partial structural diagram of the utility model；
In reference numeral：1, including shaft；2, stator；3, rotor；4, rotor field spider；5, outer ventilation circuit device；6, interior wind path

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
It please refers to Fig.1, Fig. 2, the utility model provides a kind of technical solution：A kind of air-cooled structure of New High-Voltage Motor,
Including shaft 1, stator 2, rotor 3, rotor field spider 4, outer ventilation circuit device 5, interior wind path import 6, interior wind path outlet 7, internal fan 8,
External fan 9, baffle 10.It is characterized in that：10 fluid flow direction of baffle is placed at the rotor field spider 4 of internal wind path to carry out
Change, centrifugal internal fan 8 is placed in motor left end.
Further, the 10 flare arcuation of baffle.
Further, a length of L of arc of the baffle 10, thenWherein l=kbh；
H is winding overhang length；kbIt is determined by assembly technology；kaIt is determined by processing technology, d is width of air gap.
Operation principle：The air-cooled structure of this kind of New High-Voltage Motor at work, utilizes the centrifugal interior wind of motor left end
Fan rotation generates powerful pressure, drives internal wind path fluid to move back and forth, then pass through the high temperature fluid of the internal wind path of cooler
Carry out cooling processing.Internal flow successively by baffle at the winding overhang of stator side, rotor field spider, axial ventilation ditch, turn
Sub- radial direction wind path, rotor gap, stator radial direction wind path, centrifugal fan, outer ventilation circuit device, eventually enter into stator winding end group
At recirculating network.It is thus achieved that the cooling of motor.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It cannot be a variety of to the progress of these embodiments to change, change, replace in the case where not departing from the principles of the present invention and spirit
It changes and modification, the scope of the utility model is defined by the appended claims and the equivalents thereof.
