The rotor is the rotating part of the motor. It is generally composed of permanent magnets with a certain number of pole pairs embedded on the surface of the iron core or embedded inside the iron core.

[0003] A patent entitled "An Auxiliary Tool for Installing Motor Rotor Magnets" (patent application number: CN202022468162.1) discloses an auxiliary tool for installing motor rotor magnets. It uses a split-type pushing component and a fixing component with glue to facilitate the fixing of the magnet to the iron core and reduce the damage rate of the magnet caused by collisions during installation.

In addition, manual installation will have errors in adhesion, and the force of each squeeze and adhesion will be inconsistent.

[0004] Therefore, it is necessary to propose a magnet installation auxiliary tool to solve the above problems. Utility Model Content

An L-shaped plate 6 is fixed to the bottom end of the notch 5. A motor 2 is fixed to the middle of the bottom end of the chassis 1. A rotating shaft 11 is located at the top of the motor 2. A through-hole 15 is formed on the chassis 1 for the rotating shaft 11 to pass through. An electric push rod 7 is fixed to the side of the L-shaped plate 6 near the rotating shaft 11. A pressing block 8 is fixed to one end of the electric push rod 7. A fitting groove 13 is formed on one side of the pressing block 8. A magnetic block 9 is placed inside the fitting groove 13.

[0023] In the actual operation of this utility model, the magnetic core 10 can be sleeved on the outside of the rotating shaft 11 to connect the magnetic core 10 and the rotating shaft 11. After the connection is completed, the lower pressure plate 3 can cover the top of the magnetic core 10 to provide protection.

[0024] The magnetic blocks 9 to be bonded are placed inside the fitting groove 13, and adhesive is applied to the side of the magnetic blocks 9 closest to the magnetic core 10.
