What’s Happening: Vitesco Technologies, a global leader in drive technologies and electrification solutions, is showcasing its latest innovations for more sustainable and efficient electric driving at the 44th Vienna Motor Symposium. The company is introducing a new rotor without permanent magnets as part of its fourth-generation fully integrated electric axle drive platform (EMR4, Electronics Motor Reducer). This rotor forms the core of an externally excited synchronous machine (EESM) that operates without rare earths, reducing costs and carbon footprint.
Why It Matters: The elimination of rare earths in the rotor is a significant step towards improving the sustainability and efficiency of electric vehicles. As electric cars continue to grow in popularity, finding ways to reduce their environmental impact is crucial. The EESM technology becomes more economically attractive as performance requirements for the drive increase, according to Thomas Stierle, division head of Vitesco Technologies’ Electrification Solutions.
Key Points:
- Externally excited machines offer several advantages, including cost savings, improved sustainability, and better efficiency during “sailing” mode.
- Vitesco Technologies has overcome significant challenges in designing EESM rotors, enabling the technology to compete with existing permanent magnet synchronous motors (PSMs).
- The company’s innovative winding principle makes the EESM rotor an economically attractive option for the latest drive platform.
- Vitesco Technologies is also showcasing its Battery Management System (BMS), Thermal Management Module, and other solutions for electric mobility at the Vienna Motor Symposium.
Bottom Line: Vitesco Technologies’ new rotor without permanent magnets provides a more sustainable and cost-effective alternative for electric vehicle manufacturers. As the technology continues to develop, it may play a significant role in making electric cars more affordable and environmentally friendly. The company’s commitment to transferring existing technologies to new applications further underscores its dedication to sustainability and innovation in the electric mobility sector.
