AI Technical Summary
In dusty or painted environments, the clearance between the motor shaft and the mounting hole can easily allow dust and paint particles to intrude, causing motor contamination, increased noise, and shortened service life.
A first stop is set on the rotating shaft, with its outer periphery protruding from the edge of the mounting hole and fixed by a stop groove, forming a dust barrier to reduce the risk of contaminants entering the motor and reduce friction noise.
It effectively improves the dustproof performance of the motor, reduces the risk of friction noise, ensures stable operation of the shaft, and extends the service life of the motor.

Abstract
Claims
1. An electric machine characterized in that, include: Motor body; An end cap is installed on the motor body, and the end cap has a mounting hole. A rotating shaft passes through the mounting hole and is drivenly connected to the motor body. A stop groove is provided on the outer periphery of the rotating shaft, and the stop groove is located on the side of the mounting hole away from the motor body. A first stop is fitted onto the rotating shaft and has a first stop portion extending into the stop groove. The outer periphery of the first stop protrudes from the edge of the mounting hole along an axis away from the rotating shaft.
2. The electric machine of claim 1, wherein, Both the stop groove and the first stop portion extend circumferentially along the rotating shaft. And / or, the first stop is made of an elastic material, and the first stop portion is elastically sleeved on the bottom wall of the stop groove; And / or, there is a gap between the first stop and the end cap.
3. The electric machine of claim 1, wherein, The outer periphery of the first stop is folded over on the side where the end cap is located.
4. The electric machine of claim 3, wherein, The folded portion extends straight along the axis of the rotating shaft, or the folded portion extends obliquely in a direction away from the axis of the rotating shaft; And / or, the outer edge of the mounting hole is located in the inner peripheral space of the folded portion.
5. The electric machine of claim 1, wherein, The motor further includes a second stop, which includes a mounting portion and a stop portion connected to each other. The mounting portion is connected to the end cover and / or the motor body. The second stop portion and the outer periphery of the first stop are at least partially opposite to each other in the axial direction of the rotating shaft.
6. The electric machine of claim 5, wherein, The second stop is located on the side of the first stop closer to the end cap, or the second stop is located on the side of the first stop away from the end cap; And / or, there is a gap between the second stop and the first stop; And / or, the second stop is made of an elastic material, and the mounting portion is elastically fitted onto the outer peripheral surface of the end cap.
7. The electric machine of claim 5, wherein, The outer periphery of the first stop is folded with a folded portion, and the second stop portion and the folded portion are at least partially opposite each other in the radial direction of the rotating shaft.
8. The electric machine of claim 7, wherein, The second stop includes an intersecting first stop segment and a second stop segment, wherein the first stop segment is connected between the second stop segment and the mounting portion, and extends radially toward the rotating shaft; In the direction close to the first stop, the second stop extends obliquely away from the pivot; or, the second stop extends axially toward the first stop along the pivot.
9. The electric machine of claim 5, wherein, The first stop has a mating groove on its outer peripheral surface, and the second stop extends at least partially into the mating groove, and is spaced apart from the two groove sidewalls of the mating groove in the axial direction of the rotating shaft.
10. A fan-coil unit, characterized by Including the motor as described in any one of claims 1 to 9.
