![]() ![]() In addition, the production CO2 footprint, which is higher with PSM e-motors due to magnets including rare earth materials, can be reduced by up to 50%. And we currently see no competitor that masters this technology as well as ZF.”Ĭompared to more common SESM systems, the inductive exciter can reduce losses for the energy transmission into the rotor by 15%. “This is our guiding principle for all new products. ![]() “With this magnet-free e-motor without rare earth materials, we have another innovation with which we are consistently improving our electric drive portfolio to create even more sustainable, efficient, and resource-saving mobility,” said Dr. It eliminates the drag losses created in traditional PSM e-motors, enabling better efficiency at high speed. This is said to make the motor more compact, with higher power and torque density. The company’s I2SM (in-rotor inductive-excited synchronous motor) transmits energy for the magnetic field via an inductive exciter inside the rotor shaft. ![]() The advanced magnet-free concept of SESMs (separately excited synchronous motors) is an alternative to permanent-magnet synchronous machines (PSMs) most frequently used in EVs (electric vehicles) based on magnets that require rare earth materials for their production. The automotive supplier will highlight its electrification advancements with its Porsche Taycan-based EVbeat electric concept vehicle with a powertrain designed for maximum compactness, low weight, and maximum efficiency using a new electric motor without magnets. ![]() At the IAA Mobility show in Munich, ZF will focus its exhibit on electric mobility and vehicle motion control technologies. ![]()
