New energy vehicle motor performance and life expectancy increased? It depends on the laser welding machine.

At present, new energy vehicles are selling very well, mainly because their motor performance and life expectancy have increased. How did this work? In fact, this depends on the laser welding machine. The motor of new energy vehicle is mainly composed of stator and rotor, end cover, bearing, oil cover, fan, hood and other parts. The stator core is made of silicon steel sheet welded longitudinally at a certain distance to form a complete stator. In the past, the welding of stator silicon steel sheet used to adopt traditional welding processes such as electrode arc welding, CO2 gas shielded welding and argon arc welding. These welding processes have obvious shortcomings, such as poor forming and large splash. The strong arc and ozone and other harmful oxides of argon arc welding do great harm to the human body. After the appearance of laser welding machine, the welding of motor stator begins to adopt laser welding technology, and the output laser beams of two or four machines or single machine are controlled by computer and placed around the outer circle wall of the stator, so that the welding seam needed for the stator to be tightly fixed can be completed once or twice, and the deformation can be greatly reduced. The welding is more solid, and at the same time, the complex processing technology and processing time are saved. Punched sheet welding of motor rotor is similar to that of stator welding. The difference is that the weld of rotor is on the inner wall of rotor. Laser welding also has the advantages mentioned above. The new energy vehicle motor stator and rotor are welded by laser welding machine, which improves the quality of the welded joint, increases its stability, and thus improves the motor performance and service life.铜焊丝,Copper Welding Rods,铝焊丝,aluminium welding wire,镍焊条,Nickel electrode,药皮焊条,Flux Coated Brazing Welding Rods
