Description

Technical Field

[0001] This utility model relates to a motor rotor housing and a motor rotor with easily installed magnets. Background Technology

[0002] In the field of motor technology, the rotor, as one of the core components, has a crucial impact on the overall operating characteristics of the motor due to its performance and structural design. In traditional motor rotors, the magnets are usually glued to the inner wall of the rotor housing. This fixing method lacks an effective positioning structure, resulting in insufficient precision in the installation position of the magnets and uneven magnetic field distribution, which affects the electromagnetic performance of the motor. At the same time, the complex external forces generated by the motor during operation, such as electromagnetic force, centrifugal force, and mechanical vibration, act on the magnets over a long period of time. The glue bonding method is prone to aging and failure, leading to loosening or even displacement of the magnets. This not only exacerbates the uneven magnetic field distribution but may also cause friction or collision between the magnets and other rotor components, causing equipment damage. In severe cases, it may even lead to motor failure and shutdown, affecting service life and operational safety. Utility Model Content

[0005] A motor rotor housing with easily installed magnetic tiles includes a housing with an open end. Multiple insertion strips are vertically arranged on the inner wall of the housing and evenly distributed along its circumference. A magnetic tile fixing frame is provided inside the housing. The magnetic tile fixing frame includes a connecting ring and multiple vertically arranged magnetic tile limiting posts. The multiple magnetic tile limiting posts are above the connecting ring and evenly distributed along its circumference. Magnetic tile engaging grooves are provided on the left and right sides of each magnetic tile limiting post. Insertion grooves are provided on the outer sides of the connecting ring and the magnetic tile limiting posts. An end cap is provided at one end of the housing opening, and the bottom surface of the end cap abuts against the top surface of the magnetic tile limiting post.

[0006] Preferably, there are eight of each of the connector strips and magnetic tile limiting posts.

[0007] Preferably, three magnetic tile fixing frames are provided, and the three magnetic tile fixing frames are continuously distributed along the length direction of the shell.

The magnetic tile fixing frame 3 includes a connecting ring 301 and multiple vertically arranged magnetic tile limiting posts 302. The multiple magnetic tile limiting posts 302 are above the connecting ring 301 and evenly distributed along its circumference. Magnetic tile engaging grooves 4 are provided on the left and right sides of the magnetic tile limiting posts 302. Insertion grooves 5 are provided on the outer sides of the connecting ring 301 and the magnetic tile limiting posts 302. An end cap 6 is provided at one open end of the housing 1. The bottom surface of the end cap 6 abuts against the top surface of the magnetic tile limiting post 302.

[0024] During installation, first insert the magnetic tile fixing frame 3 into the housing 1, and apply glue to the inner wall of the housing 1. Then, insert the magnetic tile between the two magnetic tile limiting posts 302, and insert the two ends of the magnetic tile into the magnetic tile snap-fit ​​groove 4. The installation of the magnetic tile is completed by bonding and limiting. The installation position of the magnetic tile can be found quickly and accurately. Furthermore, the magnetic tile fixing frame 3 and the magnetic tile snap-fit ​​groove 4 limit the magnetic tile from moving after bonding.

[0025] In this embodiment, as Figure 1 As shown, there are eight of each of the plug strip 2 and the magnetic tile limiting post 302, depending on the required number of magnetic tiles.

[0026] In this embodiment, as Figure 1 As shown, there are three magnetic tile fixing frames 3. The three magnetic tile fixing frames 3 are continuously distributed along the length direction of the shell 1. When multiple rings of magnetic tiles need to be set inside the shell 1, the corresponding number of magnetic tile fixing frames 3 can be set as needed.

[0027] In this embodiment, as Figure 5 As shown, a heat dissipation groove 7 is provided on the connecting ring 301 between two adjacent magnetic tile limiting posts 302 to promote heat dissipation and prevent the magnetic tile from overheating.

[0028] In this embodiment, as Figure 5 As shown, the inner wall of the connecting ring 301 is provided with heat dissipation holes 8 that communicate with the heat dissipation groove 7 to promote air circulation, form convection heat dissipation, and further reduce the temperature of the magnetic tile.

[0029] In this embodiment, as Figure 6 As shown, the end cap 6 includes a plug-in part 601 and a fixing part 602. The plug-in part 601 is located below the fixing part 602. The plug-in part 601 is plugged into the plug strip 2. The bottom surface of the plug-in part 601 abuts against the top surface of the magnetic tile limiting post 302 to further press the magnetic tile and prevent it from loosening.

[0030] In this embodiment, as Figure 1 and Figure 3 As shown, the fixing part 602 is provided with a plurality of first fixing holes 9 along its circumference, and the housing 1 is provided with second fixing holes 10 corresponding to the positions of the first fixing holes 9. The end cap 6 and the housing 1 are fixed by screws to ensure connection stability.

[0031] An electric motor rotor includes the aforementioned electric motor rotor housing.

[0032] In summary, in this embodiment, the installation position of the magnetic tile is quickly determined by the cooperation of the magnetic tile fixing frame 3 and the plug strip 2, and the position of the left and right ends of the magnetic tile is restricted by the magnetic tile snap-fit ​​groove 4, and the position of the upper and lower ends of the magnetic tile is restricted by the connecting ring 301 and the end cover 6, ensuring that the magnetic tile will not loosen or shift during the operation of the motor rotor, thus achieving efficient installation and firm fixation of the magnetic tile.
