New development combines the strengths of different electric motor concepts in one product. Advantages in terms of costs, resource security, and environmental compatibility by avoiding the use of rare earth elements.<\/p>\n\n\n\n

High overall efficiency of 95%, previously only achieved by Formula E racing cars. Wear-free thanks to inductive power transmission. Suitable for use in all vehicle classes.<\/p>\n\n\n\n

MAHLE is currently developing a new kind of magnet-free electric motor that does not require rare earth elements. This not only makes production more environmentally compatible, but also brings advantages in terms of costs and resource security. The central feature of the new motor is the inductive and thus contactless power transmission\u2014this allows the motor to operate wear-free and particularly efficiently at high speeds. The efficiency is above 95% at almost all operating points\u2014a level that previously has only been achieved by Formula E racing cars. MAHLE has thus succeeded in combining the strengths of various electric motor concepts in one product. This new development is easily scalable, so it can be used in anything from subcompacts through commercial vehicles.<\/p>\n\n\n\n

\u201cWith our new electric motor, we\u2019re living up to our responsibility as a sustainably operating company,\u201d says Michael Frick, Chairman of the MAHLE Management Board (ad interim) and CFO. \u201cDispensing 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.\u201d<\/p>\n\n\n\n

\u201cOur magnet-free motor can certainly be described as a breakthrough, because it provides several advantages that have not yet been combined in a product of this type,\u201d says Dr. Martin Berger, Vice President Corporate Research and Advanced Engineering at MAHLE. \u201cAs a result, we can offer our customers a product with outstanding efficiency at a comparatively low cost.\u201d<\/p>\n\n\n\n

The new traction motor from MAHLE is highly efficient\u2014at almost all operating points\u2014and really demonstrates these advantages in segments where vehicles are mostly operated in real road traffic.<\/p>\n\n\n\n

The new electric motor is also characterized by a high degree of durability, because the necessary transmission of electrical currents between the rotating and stationary parts inside the motor takes place without contact and is therefore wear-free. This makes the engine maintenance-free and suitable for a wide range of applications.<\/p>\n\n\n\n

During its development, MAHLE uses an innovative simulation process in which various motor designs are adjusted along different parameters until an optimum is found. This approach is significantly faster and cheaper than conventional processes. In this way, MAHLE is helping to quickly create the necessary technical conditions in order to advance e-mobility in a sustainable manner worldwide.<\/p>\n\n\n
