The end of the motor shaft 3 is sleeved with a sleeve 4, and the sleeve 4, the motor shaft 3 and the motor rotor 2 can be moved upward by pulling the lifting rope 8 upward, and then the inclination angle of the motor rotor 2 can be adjusted by adjusting the position of the lifting rope 8 on the adjusting portion 9. When the motor rotor 2 is adjusted to a horizontal position, the lifting rope 8 is controlled to move horizontally, so that the sleeve 4, the motor rotor 2 and the motor shaft 3 can be driven to move synchronously, thereby achieving the purpose of extracting the motor rotor 2 from the motor housing 1, and vice versa, it can be installed, thereby achieving the purpose of extracting and installing the motor rotor.

[0020] It should be noted that there is a certain gap between the sleeve 4 and the outer wall of the motor shaft 3. When the lifting rope 8 is pulled upward, the sleeve 4 and the outer wall of the motor shaft 3 are basically in contact at two points. The smaller the gap between the two, the larger the contact area. The upper end of the lifting rope 8 is provided with a crane that can drive the lifting rope 8 to rise and fall or move horizontally. By controlling the crane to drive the lifting rope 8 to move left and right, its position on the suspension arm 7 can be realized.
