Description
Technical field
The utility model belongs to motor cooling technology field, is specifically related to a kind of motor cooling structure of dust catcher.
Background technology
The heat radiation cooling of rotor and stator is directly connected to the power output and the life-span of motor, the motor cooling of prior art adopts cooling fan to brush with cooling facing to the heat radiation wing of being located at the stator appearance mostly, its motor of common in the market dust catcher is generally the inorganic shell structure, cooling blast enters through the direct outside from stator behind the inducer from the fan housing mouth and disperses to discharge, this cooling blast does not have rational airflow path, has only seldom the part stator surface of flowing through, so cooling effectiveness is very low, can not guarantee the radiating and cooling of motor, next be since motor in when work because the noise that the cooling blast that the fan high speed rotating produces is produced during through inducer is directly outwards propagated, have greater environmental impacts.
For example China Patent No. ZL 201120284410.5, and name is called the utility model patent of " a kind of structure of rotor internal fan band ventilating duct ", disclose a kind of structure of rotor internal fan band ventilating duct, and it comprises internal fan, ventilating duct, support ring.Described ventilating duct is welded on the support ring, and described support ring hot jacket is on motor shaft, and the length of described ventilating duct equals the distance of the end face of internal fan to rotor core.This utility model is provided with ventilating duct, the restriction cooling blast radially runs off, but this structure also just reduces air-flow to run off, improve the ratio of air flow direction stator, can not all be cooled off the stator of motor and the outside of rotor, therefore its effect is still undesirable, also is not suitable for the motor of dust collector cooling.
Summary of the invention
The utility model technical issues that need to address are, the motor cooling blast that overcomes prior art can't cover rotor and stator, be not suitable for the defective of motor of dust collector cooling, provide a kind of air-flow to the motor of dust collector fan in addition reasonable direction with the cooling structure of cooling motor rotor and stator effectively simultaneously.
The purpose of this utility model is achieved by following technical proposals:
OnePlant the motor of dust collector cooling structure that is provided with air guiding sleeve, comprise stator, the rotor of motor and the fan that is connected with rotor, the end of stator is connected with air guiding sleeve, the other end of air guiding sleeve is connected with inducer, the outside of inducer is connected with an end of wind scooper, fan is located at the inboard of the wind scooper other end, and rotor is connected with the centre of inducer by bearing;
