Proterial (beforehand Hitachi Metals), a producer of iron and metals, has discovered that optimizing the design of a motor utilizing its patented high-performance ferrite magnet NMF-15 can obtain the identical output as an EV drive motor that makes use of neodymium magnets.

Proterial has validated most energy of 102 kW and most rotation velocity of 15,000 rpm, in comparison with 110 kW and 10,000 rpm for a neodymium magnet.

The output of neodymium magnets for EV drive motors and mills is predicted to rise as EV manufacturing will increase, however neodymium magnets make use of neodymium, a light-weight uncommon earth, plus dysprosium and terbium, heavy uncommon earths which are in brief provide.
