Abstract
Description
Technical Field
[0001] This utility model relates to the field of stator and rotor assembly technology, specifically a stacked stator and rotor assembly. Background Technology
[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, or that converts one form of electrical energy into another.
[0003] Application number CN202222453009.0 discloses a high-performance stator and rotor assembly, relating to the field of motor technology. The assembly includes a housing and other structures. This invention, by setting a limiting ring on the rotor shaft, can limit the rotor to the inside of the motor housing, thereby preventing axial movement. This solves the problem of existing rotors easily causing axial movement when rotating inside the motor housing, leading to friction between the rotor coils and the inner wall of the motor housing, causing the insulation layer on the outer surface of the coils to peel off, resulting in short circuits and motor burnout. However, in practical use, the limiting ring is constantly in contact with and rubs against the inner wall of the motor housing, causing it to wear easily and resulting in a short service life.

The limiting mechanism includes rollers movably installed on the outside of the limiting discs and connecting members movably sleeved on the outside of the rollers.
[0007] By adopting the above technical solution, when the rotor and stator are installed inside the external motor housing, firstly ensure that the stator is located between the two limiting discs, then attach the rollers to the outside of the limiting discs, and then connect the connectors to the inner wall of the motor housing. In this way, when the rotor rotates with the limiting discs, it effectively prevents the limiting discs from rubbing against the inner wall of the motor housing, thus ensuring the service life of the limiting discs.
[0008] In a preferred embodiment, the present invention can be further configured such that two limiting discs are vertically symmetrical about the stator, and the limiting discs are made of stainless steel.

[0011] In a preferred embodiment, the present invention can be further configured such that the connector has an opening two.
[0012] In a preferred embodiment, the present invention can be further configured such that: the outer end of the connector has multiple threaded holes arranged in a matrix.
[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0014] In this invention, when the rotor and stator are installed inside the external motor housing, first ensure that the stator is located between the two limiting discs, then attach the rollers to the outside of the limiting discs, and then connect the connectors to the inner wall of the motor housing.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a stacked stator and rotor assembly. Example 1
[0028] Combination Figure 1-4 As shown, the present invention provides a stacked stator and rotor assembly, including a stator and rotor mechanism 100, a clamping mechanism 200 and a limiting mechanism 300. The stator and rotor mechanism 100 includes a rotor 110 and a stator 120 sleeved on the outside of the rotor 110.
[0029] The clamping mechanism 200 includes two limiting disks 210 sleeved on the outside of the rotor 110 and a plurality of push rods 220 installed on the inside of the limiting disks 210. The inner end of the push rods 220 is in contact with the outer wall of the stator 120.
[0030] The limiting mechanism 300 includes a roller 310 movably mounted on the outside of the limiting plate 210 and a connector 320 movably sleeved on the outside of the roller 310.
[0031] Furthermore, the two limiting discs 210 are vertically symmetrical about the stator 120. The limiting discs 210 are made of stainless steel, which has high hardness and is not easily deformed, thus ensuring its service life.
[0032] Furthermore, the multiple push rods 220 on the inner side of the limiting plate 210 are evenly spaced and arranged in a ring. The layout design of the push rods 220 can stably press against the stator 120.
[0033] Furthermore, the outer end of the connector 320 is provided with multiple threaded holes, which are arranged in a matrix to facilitate the connection between the connector 320 and the inner wall of the motor housing. Example 2
[0034] Combination Figure 1 and Figure 3 As shown, based on Embodiment 1, the limiting disk 210 has multiple openings 400, which are arranged alternately with multiple top rods 220. The openings 400 can reduce the amount of material used in manufacturing the limiting disk 210 and facilitate the dissipation of heat generated by the rotor 110. Example 3
[0035] Combination Figure 1 and Figure 4 As shown, in the above embodiment, the connector 320 has an opening 500, which can communicate with the through hole on the stator 120 to improve the air circulation inside the motor housing.
[0036] The working principle and usage process of this utility model are as follows: When the rotor 110 and stator 120 are installed inside the external motor housing, first ensure that the stator 120 is located between the two limiting discs 210, then the rollers 310 are attached to the outside of the limiting discs 210, and then the connecting piece 320 is connected to the inner wall of the motor housing. Thus, when the rotor 110 rotates with the limiting discs 210, it effectively prevents the limiting discs 210 from rubbing against the inner wall of the motor housing, ensuring the service life of the limiting discs 210.
[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
