In preparation for the Advanced E-Motor Technologies 2025 conference, Automotive IQ interviews Torsten Knorr, Senior Manger Electromagnetic and Thermal Layout and NVH of E-Machines at SEG Automotive, to discuss strategies to reduce rare earth material use in e-motor designs while preserving performance and efficiency.

Torsten shares how SEG Automotive is balancing cost-efficiency, performance, and efficiency through the use of innovative cooling systems, optimisation techniques, and cutting-edge simulations. Torsten addresses the challenges of minimising rare earth elements while maintaining motor performance and emphasises the significance of new technologies in achieving these goals, offering valuable insights for the future of sustainable e-motor development.

Interview highlights include:

• Effective methods for reducing rare earth materials while maintaining performance and efficiency 
• Key technologies enabling the shift away from rare earth materials in e-motor design 
• Challenges and solutions to reduce rare earth materials
