Compared to manufacturers of motors or batteries Kendrion only utilises small amounts of high energy permanent magnets containing Rare Earth Metals.
However, the high and volatile prices on the world market and the effects on human and environment during the production process of those materials lead to look for possibilities to completely omit or reduce the amount of material that is used within our actuators. Physically, the high energy density of the pure material is significantly higher than of any other material available on the market.
Thus a simple replacement cannot be done without drastically reducing the performance. This project shall systematically evaluate alternative possibilities and innovative concepts to the use of rare earth magnets within polarised electromagnetic actuators.
