Powerful Solutions for Electric Drives
Hairpins are bent parts made of insulated, enameled copper wire. They are used in the modern electric motors found in electric cars, hybrid vehicles, and e-bikes, where they replace the wound inductor coils that are part of conventional stators. 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.
