Background Art

[0002] During the installation of a permanent magnet motor, the rotor and stator, influenced by magnetic forces, generate mutual forces, creating certain installation difficulties. Furthermore, high precision is required during motor installation. Misalignment of the stator and rotor center axes can damage the equipment, posing a safety hazard. Furthermore, the interaction of magnetic forces creates numerous inconveniences during motor installation. Therefore, a high-precision displacement device is needed to address the issues encountered during permanent magnet motor installation. This device can address issues such as center axis misalignment and equipment damage caused by magnetic interaction during installation. This device not only reduces equipment damage but also improves installation efficiency, making it a crucial component for the assembly of permanent magnet motors. Summary of the Invention

The device uses the rotation of the lead screw to drive the motor to move in the horizontal direction, and controls the number of rotations of the handwheel to control the movement distance, thereby achieving precise regulation of the motor's centering installation distance.

[0023] 1. Its motor precise centering device has positioning pins installed on the motor housing to ensure that the center axes of the motor rotor and stator can be highly aligned during installation, reducing the uneven gap between the rotor and stator and avoiding damage to the motor caused by friction.

[0024] 2. The motor rotor is used to replace the original flywheel of the power unit output shaft, which reduces the connection space and meets the component space requirements of vehicle equipment.

[0025] 3. The handwheel is used to rotate the lead screw. The moving distance of the lead screw is adjusted by controlling the number of rotations of the handwheel to achieve precise horizontal movement of the motor. At the same time, the axial limit of the lead screw avoids violent impact.

[0026] 4. Install a bearing at the top of the screw, and use the rotation of the screw to drive the bearing forward, so as to realize the axial movement of the stator. At the same time, the bearing reduces the friction during the rotation of the screw.

[0027] 5. Install two balancing brackets above the support to ensure that the center axis of the screw and the motor coincide with each other while the screw moves.

[0028] Expected economic and social benefits

[0029] By precisely controlling the moving distance during the motor installation process, we can avoid problems such as improper installation and bumps during installation caused by magnetic influence. At the same time, positioning pins and other devices are used to ensure that the center axis of the motor coincides with the center axis of the power unit, thereby improving installation efficiency and effectively avoiding losses caused by installation errors.
