Wire bending
Wire bending, the key to the efficient manufacture of electric motors
Ready for the future of electromobility: Cover every step in hairpin technology with the comprehensive automation and digitalization portfolio from Siemens – and find the right solution for the entire electric motor production process.
Precise bending of hairpins
Precision and speed of production are the central aspects for bending hairpins – as they are crucial for all downstream processes. With the automation portfolio from Siemens, you implement all the process steps of manufacturing an electric motor with hairpin technology into your machine concepts – and benefit from efficiency and flexibility along the entire production process.
Hairpin technology paves the way for the cost-effective and highly efficient production of electric motors in large volumes
The number of vehicles is increasing at an enormous rate. In light of this, resource-conserving electric motor concepts are becoming increasingly important. The challenge is not only produce electric motors quickly and in large quantities, but also in high quality in order to enable efficient drive concepts for e-mobility. One procedure that offers enormous potential in this regard is hairpin technology. However, for the hairpins to guarantee efficient and reliable transmission of power, they have to be manufactured and inserted into the stator precisely and with very high quality. We support you in this with scalable products, engineering and standard applications. This includes a product register to track the hairpins and motor components – including their properties – along the product line and assign them to the various motors. To ensure that at the end every motor is manufactured perfectly and with extreme precision.
