The worldwide E-mobility transition. 
The number of Electric Vehicles and Hybrids is growing continuously as each of us realized the importance of environment protection. Therefore, the demands rise sharply for the production of E-mobility components, such as EV batteries, E-motors and Electric Steel stators&rotors. More and more automotive suppliers are applying new manufacturing solutions and technologies to produce high quality Electric Components. CHlaser is one of them, focusing on stator & rotor stacked laminations. With very high precision equipment, CHlaser provides top level laser cutting & welding solutions to facilitate clients’ manufacturing process.
The core of E-mobility is electric motor
CHlaser has developed a highly integrated hairpin processing and busbar copper soldering automation line, and is ready to expand the line into mass production for supporting E-drive clients. Compared with traditional round copper wire, the flat-shape hairpin will improve the copper content in the E-motor so that the motor can produce more power, significantly enlarging the range of electric vehicles. For this reason, laser processes for high-tensile materials are an absolute must during production. CHlaser advises its customers on planned applications of all drive components and checks concrete application cases. No matter which assembly it is – a differential, hairpin, busbar, stator core or its housing, rotor – laser processing makes the more compact design of electric drives possible in the first place.

Laser cutting and welding for Stator and Roter
Laser cutting and welding offer fast, precise, and cost-effective solutions for electric drive (e-drive) R&D. Laser technology enables rapid prototyping, high-quality joining of dissimilar metals, and compact machine sizes for cost savings. This accelerates the R&D timeline, reduces overhead costs, and contributes to the growth and success of the e-drive industry.

Processing high-tensile steels
Compared to conventional drives, electrified powertrains are heavily exposed to other operating conditions. For example, due to the high torques of the e-drives, direct stress is placed on the components, putting them under strain. Lasers make it possible to weld high-tensile steels with tear-resistant seams. Modulated laser welding opens up totally new areas of application, realizing further lightweight construction potential.

Uncoating and welding copper hairpins
In order to prepare hairpin welding, CHlaser use CO2 plus UV lasers that ablate the layer of insulating paint, without damaging the copper underneath it. The procedure provides more precise and faster results than mechanical stripping processes, and intelligent sensor systems ensure precise seams and top quality when welding hairpins. Thanks to the high level of reproducibility of laser welding processes, our customers achieve consistently high-tensile connections with a good level of conductivity – and this in high quantities as well.
