Specific implementation mode
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described
Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally
The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality
Novel protected range.
It is in the description of the present invention, it should be noted that term "center", "upper", "lower", "left", "right", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
The utility model and simplifying describes for ease of description, do not indicate or imply the indicated device or element must have it is specific
Orientation, with specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for description purposes only, and are not understood to indicate or imply relative importance.
As shown in Figure 1 to Figure 3, the rotation become stator location structure into：First pin hole is set on electric motor end cap 1,
Rotation become stator 2 on is provided with pin installation position, at the first pin hole and pin installation position be arranged pin 3, make rotation become stator 2 with
Electric motor end cap 1 links together, and so that rotation is become stator 2 and positioned in circumferential direction.
In the present embodiment, the pin installation position that rotation becomes on stator 2 uses pin locating notch, specifically, pin locating slot
Mouth becomes the circular arc cutaway at 2 edge of stator to be arranged in rotation.
Pin 3 includes the different cylinder of two sections of diameters, and the pin first segment 301 and diameter being specially relatively large in diameter are smaller
Pin second segment 302.
The aperture of first pin hole is more than the diameter of the cambered surface corresponding to pin locating notch, and the first pin hole and pin
First segment 301 matches, and pin locating notch is matched with pin second segment 302.
In preferred embodiments, the outer diameter D 1 of pin first segment 301 is 2mm~8mm, pin second segment 302 it is outer
Diameter D2 is 0.4~0.6 times of D1.
