[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, this embodiment provides an easy-to-install motor rotor, including a device body 1, which contains an outer shell 2. The rear end of the outer shell 2 is provided with a heat dissipation cover 4 and the front end of the outer shell 2 is provided with a locking cover 10. The locking cover 10 and the outer side wall of the outer shell 2 are provided with extension buckles 11. The extension buckles 11 have a screw hole 12 and a bolt 14 is screwed into the screw hole 12. The outer shell 2 contains a stator core 16 and a rotor 17 is inserted into the stator core 16. One end of the rotor 17 is connected to a rotating shaft 18 and a stator winding 19 is wound on the rotor 17.

[0025] Preferably, heat dissipation fins 3 are installed on the outer wall of the outer casing 2. The heat dissipation fins 3 are fixedly connected to the outer casing 2. By setting the heat dissipation fins 3, the heat generated by the operation of the internal parts of the outer casing 2 can be dissipated, avoiding heat accumulation inside the outer casing 2. A junction box 5 is installed on the upper part of the outer wall of the outer casing 2, and a maintenance plate 6 is installed on the upper part of the junction box 5. By setting the junction box 5, the parts inside the junction box 5 can be protected. By setting the maintenance plate 6, the parts inside the junction box 5 can be easily inspected and maintained. Mounting buckles 7 are installed on the left and right sides of the outer casing 2. U-shaped brackets 8 are connected below the mounting buckles 7. The mounting buckles 7 are screwed to the inner part of the outer casing 2 with bolts 9. By setting the mounting buckles 7 and bolts 9, the U-shaped brackets 8 can be connected and fixed, increasing the connection and closeness between the U-shaped brackets 8. By setting the U-shaped brackets 8, the device can be supported, ensuring the safety of the device during use.

[0026] Preferably, a bushing 15 is connected to the inner wall of the locking cover 10, and a rotating shaft 18 is inserted into the bushing 15. The rotating shaft 18 is movably connected to the bushing 15. By setting the bushing 15, the rotating shaft 18 can be limited and protected, reducing the wear between the rotating shaft 18 and the outer shell 2, extending the service life and working time of the rotating shaft 18, and reducing the possibility of wear and breakage of the rotating shaft 18. A screw hole 20 is opened in the stator core 16, and a bolt 21 is screwed into the screw hole 20. By setting the screw hole 20 and the bolt 21, the stator core 16 can be installed and fixed, ensuring the safety and stability of the stator core 16 during use.

[0027] The working principle and process of this utility model are as follows: In use, the user sequentially mounts the stator windings 19 onto the rotor 17, then inserts the rotor 17 with the stator windings 19 into the stator core 16. Next, the locking cover 10 is mounted on the front end of the outer casing 2 via the rotating shaft 18. After mounting, the extension buckle 11 of the outer casing 2 is aligned with the extension buckle 11 of the locking cover 10. After alignment, the bolt 14 is screwed into the screw hole 12 of the extension buckle 11. This completes the installation of the device, enabling the installation and fixation of the motor rotor 17, increasing the stability of the device, and ensuring the safety of the motor rotor 17 during use. When disassembly is required, the user uses a tool to remove bolt 14 from the screw hole 12 of extension buckle 11. After removal, the user pulls the locking cover 10 off the rotating shaft 18 by hand. After removal, the user pulls the rotating shaft 18 outward by hand. When the rotating shaft 18 is pulled outward, it drives the rotor 17 and stator winding 19 out of the stator core 16 until the rotor 17 is completely separated from the stator core 16. Then the user can remove the stator winding 19 from the rotor 17. The rotor 17 of the device can be disassembled according to the user's needs, which is convenient for the user to replace and maintain the rotor 17 in the future, avoiding the trouble of inconvenient disassembly of the device.
