Hairpin Technology. Stators with hairpin technology are used in connection with the manufacture of electric drive motors (traction motors) for electric vehicles, both passenger cars and commercial vehicles.
Our developers and project designers are experts in the special design and quality requirements for stators for electric traction drives. We can verify and optimise these in the context of testing and the production of prototypes in our hairpin technical centre.
Hairpin motors improve the power-to-weight ratio due to the packing density of the profile material. WAFIOS offers state-of-the-art bending technology for producing hairpins, covering everything from small batches up to high volumes.
14 kwi 2023 · Design Example and Comparison with a Stranded Winding Solution. A design comparison for a traction application motor is shown in Figure 1. The two machines are designed for the same voltage, current, and slot current density; they have been optimized for the same output performance.
HAIRPIN STATOR VERSUS CLASSIC WINDING TECHNOLOGY. The majority of today’s manufacturing processes for stators are based on vari-ous wire winding techniques, such as flyer or needle winding, in which round wire is inserted into the stator according to an intended winding scheme, FIGURE 1.
5 paź 2018 · Hairpin technology offers the necessary space for differentiation, so that the focus is on identifying the optimum product design, for example in the winding head (end turns).
By using preformed, open coil segments made of conductors with a rectangular cross-section (so-called hairpins) and the high degree of automation, this technology allows high-quality stators with the highest filling ratios to be manufactured.
