Abstract

This utility model discloses an anti-interference motor magnet, comprising: a shielding shell, the shielding shell including a positioning seat, a shielding cover provided on the top of the positioning seat, and limiting strips fixedly connected around the inner wall of the positioning seat; a shaft hole opened at the center of both the positioning seat and the shielding cover; and a magnet assembly, the magnet assembly including a rotor body, a rotating shaft passing through the center of the rotor body, and positioning components fixedly connected around the outer wall of the rotor body, with rotor magnets disposed between adjacent positioning components. This utility model utilizes the cooperation between the shielding assembly and the magnet assembly, pre-positioning the rotor magnets and rotor body with adhesive. During the installation of the external shielding positioning seat, the limiting strips compress the two positioning strips, allowing the positioning strips to clamp the rotor magnets, thus providing auxiliary positioning. This makes the installation of the anti-interference motor magnet not only simpler and faster, but also improves the positioning stability of the rotor magnets, making them less prone to detachment.

Description

Technical Field

[0001] This utility model relates to the field of motor accessory technology, specifically to an anti-interference motor magnet. Background Technology

[0002] Motor magnets are crucial components in electric motors, primarily used to generate a magnetic field that drives the motor's operation. Motor magnets are typically made of permanent magnet materials, commonly including neodymium iron boron (NdFeB) magnets, styrene cobalt (SCB) magnets, and AlNiCo (AlNiCo) magnets. These magnets play a key role in the motor, enabling efficient operation by generating and maintaining the magnetic field.

[0003] Currently, in practical applications, the rotor magnets of existing anti-interference motors are generally connected to the rotor body by adhesive bonding. Although this method is simple to manufacture and inexpensive, the adhesive strength is low, and the magnets are prone to falling off.

[0004] Therefore, we propose to design an anti-interference motor magnet. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An anti-interference motor magnet, comprising:

[0008] A shielding shell, the shielding shell including a positioning seat, a shielding cover provided on the top of the positioning seat, a limit strip fixedly connected around the inner wall of the positioning seat, and a shaft hole opened at the center of both the positioning seat and the shielding cover;

[0009] A magnet assembly, comprising a rotor body, a rotating shaft passing through the center of the rotor body, positioning components fixedly connected around the outer wall of the rotor body, and rotor magnets disposed between two adjacent positioning components;

[0010] The positioning component includes two positioning strips fixedly connected at their tails, with a limiting groove formed between the two positioning strips, and chamfers formed at the top and bottom of each positioning strip.

[0011] As a preferred embodiment of the anti-interference motor magnet described in this utility model, the top of the positioning seat is provided with an annular groove around its perimeter, and the bottom of the shielding cover is threadedly connected to the annular groove, which facilitates the installation and fixing of the positioning seat and the shielding cover to the outside of the magnet assembly.

[0012] As a preferred embodiment of the anti-interference motor magnet described in this utility model, the two ends of the rotating shaft pass through two shaft holes and extend outwards to facilitate transmission.

[0013] As a preferred embodiment of the anti-interference motor magnet described in this utility model, the limiting strip is arranged in the shape of a triangular prism, and the limiting strip corresponds and fits into the limiting groove. By inserting the limiting strip into the limiting groove, it is convenient to squeeze the positioning strips on both sides to fix the rotor magnet, thereby improving the stability of the rotor magnet positioning.

[0014] As a preferred embodiment of the anti-interference motor magnet described in this utility model, the two ends of the rotor magnet are bonded to the outer wall of the rotor body with glue. Only the two ends are bonded, and then fixed with positioning parts on both sides. This not only makes disassembly easy, but also makes the fixing firm and facilitates the positioning of the rotor magnet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the cooperation between the shielding component and the magnet component, and uses glue to pre-position the rotor magnet and the rotor body. When installing the external shielding positioning seat, the limiting strip squeezes the two positioning strips, allowing the positioning strips to clamp the rotor magnet and play an auxiliary positioning role. This makes the installation of the anti-interference motor magnet simpler and faster, and also improves the positioning stability of the rotor magnet, making it less likely to fall off.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 This utility model provides an anti-interference motor magnet, comprising:

[0026] The shielding housing includes a positioning base 1, a shielding cover 2 on the top of the positioning base 1, and an annular groove 101 around the top of the positioning base 1. The bottom of the shielding cover 2 is threadedly connected to the annular groove 101, which facilitates the installation and fixing of the positioning base 1 and the shielding cover 2 to the outside of the magnet assembly.

[0027] Limiting strips 3 are fixedly connected around the inner wall of the positioning seat 1, and shaft holes 4 are opened at the center of both the positioning seat 1 and the shielding cover 2.

[0028] The magnet assembly includes a rotor body 5, with a rotating shaft 6 passing through the center of the rotor body 5. The two ends of the rotating shaft 6 pass through two shaft holes 4 and extend outward to facilitate transmission.

[0029] The rotor body 5 is fixedly connected to the outer wall of the surrounding area with positioning components 7. The positioning components 7 include two positioning strips 701 fixedly connected to the tail end. A limit groove 702 is opened between the two positioning strips 701. The top and bottom ends of the positioning strips 701 are both provided with chamfers 703.

[0030] In this embodiment, the limiting strip 3 is arranged in the shape of a triangular prism, and the limiting strip 3 corresponds to and fits into the limiting groove 702. By inserting the limiting strip 3 into the limiting groove 702, it is convenient to squeeze the positioning strips 701 on both sides to fix the rotor magnet 8, thereby improving the positioning stability of the rotor magnet 8.

[0031] Rotor magnets 8 are provided between two adjacent positioning components 7. The two ends of the rotor magnets 8 are bonded to the outer wall of the rotor body 5 with glue. Only the two ends are bonded, and then fixed with the positioning components 7 on both sides. This not only makes disassembly easy, but also makes the fixing firm and facilitates the positioning of the rotor magnets 8.

[0032] When in use, apply special adhesive to both sides of the rotor magnet 8 and bond it to the outer wall of the rotor body 5. At this time, the bonding points are only at both ends of the rotor magnet 8, which makes it easy to disassemble later.

[0033] After inserting all the rotor magnets 8 between two adjacent positioning pieces 7, the positioning seat 1 is then fitted onto the bottom of the rotor body 5. At the same time, the limiting strips 3 are inserted into their respective limiting grooves 702. Through the insertion of the limiting strips 3, the positioning strips 701 on both sides are brought closer to the rotor magnets 8, so that the positioning strips 701 clamp the rotor magnets 8, thereby improving the positioning stability of the rotor magnets 8.

[0034] Finally, the shielding cover 2 is threaded onto the top of the positioning seat 1, and the motor magnet is assembled. The shielding assembly consisting of the shielding cover 2 and the positioning seat 1 provides sufficient protection for the rotor magnet 8, preventing external strong magnetic fields from interfering with the normal operation of its internal rotor.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
