Connecting plates 4A, 4B have positioning groove edges 6A, 6B formed by turning to position and install a rotor bearing seat 7A, 7B, and the motor stator 1 can be sleeved with the motor rotor 2 through the rotor bearing seat 7A, 7B, so that The motor stator 1 is positioned and combined with the motor rotor 2 .

This known motor stator combined structure, it passes through the circular hole 3A on a plurality of stacked silicon steel sheets 3 through the stud 5 and is screwed on the two adapter plates 4A, 4B, so that the stud 5 is stacked. 5 is not closely matched with the circular holes 3A distributed on the silicon steel sheets 3, so it is necessary to align individual silicon steel sheets 3 to ensure that they are concentrically stacked, and to ensure that the central axis of the positioning groove edges 6A, 6B formed by turning is consistent with the stacked The silicon steel sheets 3 are concentric, and the stacked silicon steel sheets 3 and the adapter plates 4A, 4B must be sent to the lathe for processing, so special fixtures and large lathes are required, resulting in high processing costs, and thus difficult to manufacture Difficult to reduce costs.

Utility model content

Therefore, the main purpose of the present utility model is to disclose a motor stator combination structure that is easy to manufacture and has considerable precision, so as to reduce the manufacturing cost.

It can be seen from the above that, in order to achieve the above purpose, the utility model is an improved motor stator combination structure, which includes a plurality of silicon steel sheets, two rotor bearing seats and a number of pins, wherein the plurality of silicon steel sheets have a number of perforations around the periphery , and the plurality of silicon steel sheets are stacked together, the two rotor bearing seats are arranged on the left and right sides of the plurality of silicon steel sheets, and the rotor bearing seats are provided with buried holes corresponding to the perforations of the silicon steel sheets, and the several pins have The same length, and the diameter of the several pins is equal to the perforation aperture of the multiple silicon steel sheets to achieve the purpose of tight fit, by pressing through the perforations of the multiple silicon steel sheets, all the silicon steel sheets are concentric and parallel. At the same time, it penetrates into the buried hole fixed on the rotor bearing seat, and really interferes with the rotor bearing seat.

According to this, the plurality of silicon steel sheets and the rotor bearing seat are tightly fixed by the plurality of bolts, so the rotor bearing seat and the plurality of silicon steel sheets can be stacked together concentrically, and because the plurality of bolts have the same length, they can be Making the two rotor bearing seats parallel to each other and perpendicular to the stacking direction of the silicon steel sheet is simpler and easier than the known process, which can reduce the manufacturing cost and meet the needs of users.

Detailed ways

In order to have a deeper understanding and recognition of the features, purposes and effects of the present utility model, the preferred embodiments are now listed and described as follows with the accompanying drawings:

As shown in Figure 2 and Figure 3, the utility model includes a plurality of silicon steel sheets 10, two rotor bearing housings 20A, 20B and several pins 30, wherein the plurality of silicon steel sheets 10 have a number of perforations 11 around the periphery, and the The perforations 11 on a plurality of silicon steel sheets 10 are equally divided and evenly arranged. It is worth noting here that the number of perforations 11 can be appropriately increased or decreased according to the accuracy required by the user. The accompanying drawings of the utility model take eight as an example, of which It is a preferred embodiment but not limited thereto. Moreover, the plurality of silicon steel sheets 10 are stacked together, the two rotor bearing seats 20A, 20B are arranged on the left and right sides of the plurality of silicon steel sheets 10, and the rotor bearing seats 20A, 20B are provided with holes corresponding to the silicon steel sheets 10. 11 of the buried holes 21, and the plurality of plugs 30 have the same length, and the diameter of the plurality of plugs 30 is equal to the diameter of the through holes 11 of the plurality of silicon steel sheets 10.

The utility model allows the pins 30 to pass through the perforations 11 of the plurality of silicon steel sheets 10 urgently, and at the same time penetrate into the buried holes 21 fixed on the rotor bearing seats 20A, 20B, and interfere with the rotor bearing seats 20A, 20B .
