It’s basically maintenance-free.
Almost five years ago, Honda announced it has developed the world’s first practical application of a hot deformed neodymium magnet that does not contain rare earth metals. At the time, this was considered an important breakthrough for the industry as this practically meant Honda could produce electric motors without heavy rare earth metals such as dysprosium and/or terbium. Now, Mahle has taken things to the next level.
The German automotive parts supplier has just announced its first-ever magnet-free electric motor. It’s currently in the final stages of development and its most important characteristic is that it doesn’t require rare earth elements. Mahle says the technology breakthrough not only “makes production more environmentally compatible” but also brings “advantages in terms of costs and resource security.”
“With our new electric motor, we’re living up to our responsibility as a sustainably operating company,” Michael Frick, Chairman of Mahle, comments “Dispensing with magnets and therefore the use of rare earth elements offers great potential not only from a geopolitical perspective but also with regard to the responsible use of nature and resources.” For the full story, check out this article from Motor 1.
