Electric drive technology is a key element in reducing global CO2<\/sub> emissions. With our technologies, we are helping to improve the carbon footprint of the electric motor.<\/strong><\/p>\n<\/div>\t<\/div>\n<\/div>\n<\/div><\/div>

Saving through product design<\/h2>\n

Segmentation<\/a> saves a lot of material. The production of one ton of electrical steel strip generates a carbon footprint of approx. 2.4 kg CO2<\/sub> e\/kg steel. Traditional and widely used progressive die cutting (with simultaneous production of stator and rotor) results in a high proportion of scrap (approx. 50%) of high-quality electrical steel strip! As a result, one ton of electrical steel strip punched in a progressive die cut and installed in the finished electric motor generates a carbon footprint of 4.8 kg CO2<\/sub> e\/kg steel! Segmentation reduces the scrap content<\/a> in the stator to 15 to 20% of the high-quality electrical steel strip. Thus, one ton of segmented<\/a> electrical steel strip punched and installed in the finished electric motor generates a carbon footprint of approx. 2.9 kg CO2<\/sub> e\/kg. That\u2019s a big difference. Added to this are the other benefits of segmentation<\/a> such as lower material costs, more precise lamination stacks, and more.<\/p>\n<\/div>\t<\/div>\n<\/div>\n\n\t\n\t

Savings thanks to production processes<\/h2>\n

The BPS\u00ae<\/a> production process produces efficient stator segments, thus making it possible to utilize the CO2<\/sub> reduction shown above in large-scale production. The production process is then optimized in a closed machine with low punching forces and efficient bonding stations. The system includes water cooling and enables heat recovery. On-site production<\/a> in the following process step saves on transportation, which further reduces the carbon footprint (see our article<\/a>).<\/p>\n

The EPS\u00ae system<\/a> for fast bonding of stators and rotors is very efficient as well. The heat is fed directly into the stack and, depending on the design, the waste heat can also be recovered. Compared to the familiar continuous furnace, this means significant energy savings and a reduction in the carbon footprint.<\/p>\n<\/div>\t<\/div>\n<\/div>\n\n\t\n\t
