Abstract
The utility model discloses a fan, which comprises an outer frame (1), fan blades and a motor. The fan blades are fixed on a motor rotor (3), the motor is an outer rotor motor, a motor stator (4) is fixedly connected with the outer frame (1), a motor rotating shaft (5) is rotatably connected with the stator (4), and the center of the motor rotor (3) is fixedly connected with one end of the motor rotating shaft (5). The fan is large in air outlet quantity, high in work efficiency and long in service life.
Description
Technical field
The utility model relates to a kind of blower fan.
Background technique
Blower fan generally 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.The rotor of inner rotor motor quick heating at work makes the working efficiency of motor not high in addition, and general work efficient is about 30%-40%; And the rotor profile size is little, and heat radiation is slow, thereby burns motor easily, shortens the working life of motor.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides that a kind of air output is big, high working efficiency, and the blower fan of long service life.
Technical solution of the present utility model is, a kind of blower fan with following structure is provided: it comprises housing, fan blade and motor, described fan blade is fixed on the rotor, described motor is an external rotor electric machine, described motor stator is fixedlyed connected with housing, described machine shaft and stator are rotatably connected, and the central part of described rotor is fixedlyed connected with an end of machine shaft.
After adopting above structure, the utility model blower fan compared with prior art, have the following advantages: adopt outer rotor motor driven, fan blade and rotor are fixed, increase the starting torque of fan blade, and external rotor electric machine when work rapid heat dissipation, improved the working efficiency of blower fan, can reach more than 57% by the efficient of repeatedly testing and detect axial-flow blower, air quantity promotes 155m
3/ hour more than, electric machine temperature rise drops to about 57K.
As a kind of improvement, described fan blade comprises blade and blade seat, a fixedly connected steel flange on the described blade seat, and described steel flange is connected by screw with rotor.Make fan blade be fixed on the rotor outer rim firmly by steel flange and fixedlying connected of rotor, improved the stability of blower fan.
