Abstract

Provided is a high voltage motor rotor heat radiation structure, comprising a motor shaft, a rotor iron core, balance rings, and a fan, wherein one end of the motor shaft is provided with a balance ring having blades via interference fit; and the other end of the motor shaft is provided with a balance ring having a ventilating duct and blades via interference fit and is also connected with an inner fan via a fan button. When the motor rotor rotates, the blades mentioned above and the fan will form a cooling cycle inside the motor, thereby effectively cooling down the interior of the motor and improving the heat radiation effect of the high voltage motor, which can prolong the service lifetime of a three-phase asynchronous motor. The high voltage motor rotor heat radiation structure features a simple and compact structure, reasonable design, and convenient manufacturing.

Description

High-voltage motor rotor radiator structure
Technical field
The utility model belongs to motor manufacturing technology field, particularly relates to a kind of high-voltage motor rotor radiator structure.
Background technology
At present, the application of high-voltage motor is extensive day by day, but common high-voltage motor is because its overall dimension is bigger; Therefore the installing space that needs is bigger, in order to solve the limited problem of installation space, has designed the compact high-voltage motor; Compact high-voltage motor overall dimension is little than common electric machine; But its thermal diffusivity is relatively poor relatively, the inner normal cooling of high-voltage motor is affected, and then has shortened the useful life of threephase asynchronous.
Summary of the invention
The utility model provides a kind of high-voltage motor rotor radiator structure that improves high-voltage motor internal heat dissipating effect and can prolong its useful life for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
High-voltage motor rotor radiator structure; Comprise motor shaft, rotor core, gimbal and fan; It is characterized in that: interference fit is equipped with the gimbal of band flabellum on said motor shaft one end, and interference fit is equipped with the gimbal of band ventilating duct and flabellum and is connected with internal fan through the fan key on the other end.
The utility model can also adopt following technical scheme:
The gimbal of said band flabellum is for being welded with blade structure on gimbal.
The gimbal of said band ventilating duct and flabellum is for being welded with ventilating duct and blade structure on gimbal.
Said internal fan is a welded type ox horn type internal fan.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; And interference fit is equipped with the gimbal of being with flabellum on motor shaft one end, and interference fit is equipped with the gimbal of band ventilating duct and flabellum and is connected with internal fan through the fan key on the other end.When rotor rotated, above-mentioned flabellum and fan can make motor internal form a cool cycles, and motor internal is played good cooling effect, had improved the thermal effect that high-voltage motor looses.So not only can prolong the useful life of threephase asynchronous, but also have advantages such as simple and compact for structure, reasonable in design, easily manufactured.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, motor shaft; 2, the gimbal of band flabellum; 3, balance weight; 4, cast-aluminum rotor is unshakable in one's determination; 5, rotor core key; 6, the gimbal of band ventilating duct and flabellum; 7, welded type ox horn type internal fan; 8, internal fan key.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, high-voltage motor rotor radiator structure comprises that motor shaft 1, cast-aluminum rotor are unshakable in one's determination 4, gimbal 2, gimbal 6 and fan 7, and cast-aluminum rotor unshakable in one's determination 4 is mounted on the motor shaft 1 through rotor core key 5.Said motor shaft 1 is positioned at the gimbal 2 that interference fit on rotor one end is equipped with the band flabellum, and the gimbal 2 of said band flabellum is for being welded with blade structure on gimbal.Be positioned at the gimbal 6 that interference fit on the rotor other end is equipped with band ventilating duct and flabellum, the gimbal of said band ventilating duct and flabellum is for being welded with ventilating duct and blade structure on gimbal.On motor shaft, be connected with internal fan through internal fan key 8, said internal fan is a welded type ox horn type internal fan 7.
When rotor rotated, the flabellum on the said gimbal, ventilating duct and fan can make motor internal form a cool cycles, and motor internal is played good cooling effect, have improved the radiating effect of high-voltage motor.
