[0002] The stator of the motor is installed in the motor casing, which is usually fixed by interference fit and tightened with set screws. The thin-walled motor casing made of steel plate cannot use set screws, and can only increase the amount of interference, so the motor casing cannot Too thin, other stator positioning methods are not very reliable

Embodiment Construction
[0058] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment, see Figure 1-29 :
[0059] A stator positioning method of a thin-walled motor is as follows: 1. The stator 16 with windings is installed in the thin-walled motor casing 15; 2. Bushes 19 are installed at both ends of the stator 16, and the bushes make the stator 16 axially positioned; 3. 15 ends of the thin-walled motor casing are equipped with end caps, which can block the bushing 19, and the end caps support the bearing of the rotor 17.
[0060] The tight fit between the bushing 19 and the thin-walled motor casing 15 is equivalent to increasing the thickness of the thin-walled motor casing and increasing the strength of the thin-walled motor casing. The bushing 19 and the thin-walled motor casing 15 are closely matched or the bushing and the thin-walled motor casing are welded, and the positioning of the bushing is not necessarily blocked by the e...

The invention relates to a stator positioning method of a thin-wall motor, a water pump with a water-cooled motor and an aerator. The stator positioning method of the thin-wall motor includes that (1) a stator with a winding is installed in a thin-wall motor case; (2) bushes are disposed at two ends of the stator, and the stator is axially positioned by the bushes; and (3) end covers are installed at two ends of the thin-wall motor case, the end covers can block the bushes, and the end covers support a bearing of a rotor. By means of the method, the stainless steel thickness of the thin-wall motor case can be substantially reduced, and the cutting-free machining of the motor case inner wall is achieved. The outer diameter of an upper end cover of the thin-wall water-cooled motor is larger than that of a lower end cover of the thin-wall water-cooled motor so as to provide rotating space for a nut, the outer edge of the lower end cover of the thin-wall water-cooled motor is in a stepped shape, a small end of the stepped shape is matched with the inner edge of the thin-wall motor case, the outer diameter of the upper end cover of the thin-wall water-cooled motor is matched with a large end of the thin-wall water-cooled motor, a long stud penetrates through a silicon steel sheet to be fixed in a screw hole of the lower end cover, the upper end of the long stud penetrates through the upper end cover to be fastened by the nut, the bushes are installed at two ends of the stator, and the stator is axially positioned by the bushes.
Description
technical field [0001] The invention relates to a motor, in particular to a positioning method of a motor stator in a thin-walled motor casing, a water pump and an aerator with a water-cooled motor. Background technique [0002] The stator of the motor is installed in the motor casing, which is usually fixed by interference fit and tightened with set screws. The thin-walled motor casing made of steel plate cannot use set screws, and can only increase the amount of interference, so the motor casing cannot Too thin, and other stator positioning methods are not very reliable. Contents of the invention [0003] The purpose of the present invention is to provide a stator positioning method of a thin-walled motor, a water pump and an aerator with a water-cooled motor. [0004] The purpose of the present invention is achieved like this: [0005] A stator positioning method for a thin-walled motor casing: [0006] 1. The stator is installed in the thin-walled motor casing; [...
