Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of low-noise outer rotor motor.
Background technology
The main application of external rotor electric machine provides power for the low-noise centrifugal ventilation blower, is being connected of blower fan and motor fixedly to be formed with screw by the terminal pad of motor and the mid-game on the draught fan impeller.The motor field frame of present domestic low-noise outer rotor motor manufacturer all adopts iron casting or aluminium casting, and form is three box substantially: motor casing and two end cap structure, or two is box: casing and end cover structure.Above-mentioned traditional combining form makes things convenient for the processing approach extensive though draw materials, and it is big that ferro-aluminum foundry goods ubiquity allowance, and technology is loaded down with trivial details, cost height, shortcoming such as rate of finished products is low.And need on foundry goods, hole when assembling because of it, tapping, shell must have certain thickness like this, waste of raw materials is too big.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and cost is low, the motor of high efficiency.
The technical solution adopted in the utility model is:
A kind of low-noise outer rotor motor, comprise motor shaft, rotor, stator and motor field frame, described rotor and stator lay respectively in the motor field frame, described motor shaft is fixedly connected on the stator middle part and passes the motor field frame middle part, described motor field frame is divided into upper shell and lower house two parts, the fovea superior place of recess and lower house is fixed with the bearing capping respectively under the described upper shell top, described motor shaft passes bearing capping middle part, described upper shell and lower house be respectively by the disposable drawing and forming of steel plate, and described upper shell and lower house junction are by with last, the terminal pad of lower house one is fixedly connected.
The terminal pad of described upper shell or lower house is directly fixedlyed connected with the outer rotor blower fan impeller.
Described terminal pad is stuck on the blade of outer rotor blower fan impeller by the jag of its circumference.
Be fixed with the mid-game of annular on the terminal pad of described upper shell or lower house, described mid-game is fixedlyed connected with the outer rotor blower fan impeller.
Described mid-game is stuck on the blade of outer rotor blower fan impeller by the jag of its circumference.
Motor field frame described in the utility model is divided into upper shell and lower house two parts, the fovea superior place of recess and lower house is fixed with the bearing capping respectively under the described upper shell top, described motor shaft passes bearing capping middle part, described upper shell and lower house are respectively by the disposable drawing and forming of steel plate, described upper shell and lower house junction are by with last, the terminal pad of lower house one is fixedly connected, in the said structure since upper shell and lower house respectively by the disposable drawing and forming of steel plate, cancelled end cover structure, need not cut, save raw material greatly, reduced production cost; Terminal pad is the flange of upper shell or the direct disposable drawing and forming of lower house in addition, has also simplified technological process.
The terminal pad of upper shell described in the utility model or lower house is directly fixedlyed connected with the outer rotor blower fan impeller, described terminal pad is stuck on the blade of outer rotor blower fan impeller by the jag of its circumference, this structure is connected as a single entity motor and draught fan impeller, reduced the installation procedure of motor and impeller, and original motor and draught fan impeller fit together all will do dynamic and static balance before installation after again.
As another kind of execution mode, be fixed with the mid-game of annular on the terminal pad of upper shell described in the utility model or lower house, described mid-game is fixedlyed connected with the outer rotor blower fan impeller, described mid-game is stuck on the blade of outer rotor blower fan impeller by the jag of its circumference, avoided the motor terminal pad of big specification can't disposable drawing and forming like this, be connected with draught fan impeller by the mid-game that is fixed on the terminal pad, thereby motor and draught fan impeller are connected as a single entity, reduced the installation procedure of motor and impeller, thereby increased work efficiency.
Advantage of the present utility model: simple in structure, high efficiency, cost is low, reliable working performance, repair demolition is convenient, long service life.
