The application of laser welding technology in the welding process of new energy vehicle motors is a typical example of Zhongke Yuchen in many welding cases. The main accessories of the automatic laser welding equipment for new energy vehicle motors are imported products, and the welding process is mature and stable.


Motor rotor


Motor stator


Laser welding of motor stator tap

The circumferential welds between the copper rings of the rotor of three-phase asynchronous motors were usually made using induction brazing or direct integral casting processes, which cannot meet the current requirements for high-performance motors; In addition, welding processes such as arc welding and resistance welding were commonly used before the welding of the stator and coil hairpin of the motor. The deformation generated by welding is large, the heat affected zone is large, and the heat generated by welding also affects the magnetic steel and insulation layer inside the assembled motor body. Nowadays, laser welding is used, which has concentrated energy, high density, high heating efficiency, and fast speed. Therefore, the deformation of the base material is small, the non melting zone metal is less affected by heat, and the welding strength is high, which can meet the requirements of various motor indicators.
