Detailed Description
Referring to fig. 1-3, the low-noise cooling shaded-pole motor for the fan comprises a squirrel-cage rotor 10 and a stator assembly from top to bottom in sequence; the stator assembly comprises a stator and a framework 1 for fixing the stator, wherein the framework comprises a winding framework 2; an insulating wing 4 is arranged at the upper part of one end of the winding framework, and an included angle between the insulating wing and the winding framework is a right angle (as shown in figure 1); and wiring grooves 5 are formed in the front end face and the rear end face of the framework. Because the included angle between the insulating wing and the winding framework is a right angle, the insulating wing covers the copper wire, and the current can be effectively prevented from leaking; the wiring groove is arranged, so that wiring is facilitated, and the wiring positions of the enameled wire and the power line are fixed and the isolation and insulation effects can be achieved.
The wiring groove is a square wiring groove. And a square wiring groove is adopted, so that the wiring space is larger, and the wiring is convenient.
The length of the wiring groove is less than half of the length of the end face of the framework. Because the length of the wiring groove is less than half of the length of the end face of the framework, power lines on the front end face and the rear end face penetrate out from the same side, and subsequent installation is facilitated.
The framework is H-shaped. The framework adopts an H-shaped structure, so that the installation is convenient on one hand, and the winding is convenient on the other hand.
The middle part of the winding framework is a cavity. The center of the winding framework adopts a cavity structure so as to be convenient to install with the iron core.
And a bearing of the motor shaft 11 in the center of the squirrel-cage rotor is a pure copper bearing. The pure copper bearing is adopted, so that the surface smoothness can be improved, and the noise reduction performance is improved.
Five threading holes 12 are uniformly distributed at the bottoms of the front end surface and the rear end surface of the framework. The cable routing is facilitated by the arrangement of the threading holes.
The thickness of the joint between the insulating wing and the winding framework is smaller than that of the insulating wing. The insulating wing can be folded conveniently due to the fact that the thickness of the connecting part is small.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
