High performance combined with small size and low weight are key requirements for electric drives. In applications with particularly high-performance demands such as aviation or motorsports, laminations made of cobalt-iron alloys are commonly used. Compared to conventional electrical steel, this typically allows for 20-30 % higher power densities to be achieved. However, a technology transfer to road vehicles or high-performance industrial applications has rarely been practical, as the costs of this racing technology and the high-performance material it contains are often preclusive. After years of development, VAC has now closed the gap between high performance and affordability. The new VACOFLUX X1 material is clearly positioned in the ‘Goldilocks zone’ between inexpensive but low-performance electrical steel and the ultra-high-performance solutions of increased cobalt content materials. In addition to the new X1 alloy, optimum material utilization through segmentation and VAC’s innovative interlocking technology opens up further potential for significant cost reductions.
