Hairpin stator technology for electric powertrains | High-performance assembly solutions for EV motors
Hairpin stator technology for next-generation electric powertrains
Our Innovations & Prototypes department supports key players in electric mobility with the development of high-performance assembly solutions for electric powertrains and EV motors.
⚡ An advanced solution for electric motor efficiency
At the core of this achievement is the hairpin stator technology, now widely adopted in high-efficiency electric motor design. Used in automotive and broader electric mobility applications, this architecture significantly improves:
- Power density
- Energy efficiency
- Motor compactness
To meet the demanding requirements of this application, we implemented two complementary industrial processes:
✔️ Laser welding of copper hairpins for high-precision electrical connections
✔️ Resistance brazing to ensure reliable phase connector integration
The combination of these technologies guarantees excellent joint quality, electrical performance, and long-term reliability.
