[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1 Please see Figures 1-6 The present invention provides a technical solution: a rotor steel cylinder, including an outer cylinder 1 and an inner cylinder 2, the inner cylinder 2 being disposed inside the outer cylinder 1, and a plurality of receiving grooves 24 being evenly distributed on the inner cylinder 2, the receiving grooves 24 being used to receive magnetic steel sheets.

[0027] The inner cylinder 2 includes a placement cylinder 21, which has a cylindrical structure. Multiple protrusions 23 are provided on the inner wall of the placement cylinder 21. The multiple protrusions 23 are evenly distributed around the axis of the placement cylinder 21, and a receiving groove 24 is formed between two adjacent protrusions 23.

[0028] Multiple protrusions 22 are provided on the outer wall of the placement cylinder 21, and the multiple protrusions 22 are evenly distributed around the circumference of the placement cylinder 21 along its axis, such as... Figure 2 As shown, three protrusions 22 are provided, and the cross-section of the protrusions 22 can be set as a hexagonal structure; in addition, the entire inner cylinder 2 adopts an integral molding structure; the side of the protrusion 23 away from the placement cylinder 21 is an arc surface structure, the diameter of the arc surface is equal to the diameter of the inner ring surface of the ring part 12, and the arc surface is coaxial with the ring part 12.

[0029] The outer cylinder 1 is composed of a main body 11 and a ring 12. The ring 12 is disposed at one end of the main body 11, and the ring 12 and the main body 11 are integrally formed. The placement cylinder 21 is fitted inside the main body 11, and one end of the placement cylinder 21 abuts against the ring 12. Furthermore, the placement cylinder 21 is fixed to the main body 11 by adhesive or the like.

[0030] A slot 13 is provided on the main body 11. The slot 13 is structurally adapted to the protrusion 22. The number of slots 13 and protrusions 22 are equal and their positions correspond. Each protrusion 22 is fitted into the corresponding slot 13. The cross-section of the slot 13 is also set as a hexagonal structure. By the cooperation of multiple protrusions 22 and multiple slots 13, the inner cylinder 2 is fitted into the outer cylinder 1.

[0031] In this embodiment, the outer cylinder 1 and the inner cylinder 2 adopt a split structure; when installing the magnet, the inner cylinder 2 is in the removed state to install the magnet, which facilitates the installation and fixation of the magnet; after the magnet is placed, the protrusion 22 is fitted into the slot 13 and one end of the placement cylinder 21 is made to abut against the ring part 12; finally, the inner cylinder 2 is fixed to the outer cylinder 1 by adhesive such as adhesive glue.

[0032] Example 2 See again Figure 1 and Figure 6 Based on Embodiment 1, one end of the protrusion 23 is flush with the end of the placement tube 21 away from the annular portion 12, and the length of the protrusion 23 is set to be less than the length of the placement tube 21. Specifically, the protrusion 22 can be set to be between three-quarters and four-fifths of the length of the placement tube 21, and the length of the protrusion 22 is greater than half the length of the placement tube 21.

[0033] The above setup ensures the magnets are securely placed while reducing manufacturing costs and the weight of the entire rotor cylinder to some extent.
