Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor assembly, and more particularly to a horizontal split permanent magnet motor assembly device. Background Art
[0002] Currently, with the iterative upgrades in technology from new energy vehicle manufacturers, some manufacturers require split permanent magnet motors (PMMs) with the motor rotor mounted directly on the transmission. The motor's front cover and transmission end cover are combined into one. The stator and rotor of the split PMM motor are assembled at the customer's site. After the motor is installed and the rotor is secured, the stator is inserted horizontally. During the assembly process, the stator vibrates violently during insertion due to the combined effects of strong magnetic attraction and gravity. This can easily cause scratches and bumps on the stator winding ends, leading to burnout during operation.
[0003] Traditional stator-rotor assembly systems mostly use a vertical assembly method, with the stator fixed and the rotor inserted downward from above, eliminating the effects of gravity on motor assembly. However, this method is only suitable for motors with separate end caps. Furthermore, traditional stator-rotor assembly systems assemble the stator and rotor completely before the entire unit is assembled into the gearbox. This does not involve a fixed rotor and a horizontal insertion of the stator. Therefore, traditional stator-rotor assembly systems cannot solve current assembly problems. Utility Model Content
