The axial flow fan is driven by the outer rotor motor; the fan blade is fixed with the motor outer rotor so as to increase the starting torque of the fan blade; the outer rotor motor can quickly dissipate the heat during work so as to improve the work efficiency of the axial flow fan; through multiple experiments and detections, the efficiency of the axial flow fan can achieve the efficiency by over 55 percent and the air quantity is improved by over 150m<3>/h; and meanwhile, the temperature rise of the motor is reduced to be about 60K and the service life of the motor can be prolonged.
Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to a kind of axial-flow blower.
Background technique
Conventional axial-flow blower adopts inner rotor motor to drag fan blade, because the axial dimension of this motor is big, makes starting torque not enough, causes air output little.In addition, the rotor of inner rotor motor is quick heating at work, makes the working efficiency of motor not high, and general work efficient is about 35%～40%; And the boundary dimension of internal rotor is little, and heat radiation is slow, burns motor easily, thereby shortens the working life of motor.
The model utility content
The utility model is big at the axial dimension of conventional axial-flow blower, makes starting torque not enough, causes air output little, and motor working efficiency is not high, the deficiency that shortens working life provides that a kind of air output is big, high working efficiency, and the axial-flow blower of long service life.
The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of axial-flow blower comprises pedestal, housing, fan blade and motor, described fan blade is fixed on the motor, described motor is fixed on the pedestal, described fan blade and motor are arranged in the housing, described motor is an external rotor electric machine, it comprises rotor, motor stator and machine shaft, described machine shaft and base bearing cooperate, described motor stator is arranged on the inside of rotor, be rotationally connected between described machine shaft and the motor stator, described motor stator is fixedlyed connected with housing.
The beneficial effects of the utility model are: the utility model axial-flow blower adopts outer rotor motor driven, fan blade and motor outer rotor are fixed, increased the starting torque of fan blade, and rapid heat dissipation during external rotor electric machine work, improved the working efficiency of axial-flow blower, by repeatedly testing and detecting, the efficient of axial-flow blower can reach more than 55%, and air quantity promotes 150m
3/ hour more than, simultaneously electric machine temperature rise drops to about 60K, has prolonged the working life of motor.
Further, described fan blade comprises blade and blade seat, a fixedly connected steel flange on the described blade seat, and described steel flange is fixedlyed connected with rotor by screw.
Further, described blade seat is fixedlyed connected by colding pressing with rotor.
