Mahle Develops Tool Kit for Electric Motors

Jun 25, 2023

Mahle has developed a new technology kit for electric motors that combines the advantages of its SCT (superior continuous torque) and MCT (magnet-free contactless transmitter) electric motors, the company said. The “perfect motor,” as Mahle calls it, combines permanently high peak power, contactless and wear-free power transmission, the absence of rare earths and maximum efficiency.

“With this unique technology toolbox for electric motors, we can offer our customers customized electrification solutions for any vehicle class, application, or even brand philosophy,” said Arnd Franz, chairman of the MAHLE Group management board and CEO.

Electrification is a future strategy field within the framework of the MAHLE 2030+ Group strategy. Other fields include thermal management and highly efficient, green combustion engines. MAHLE will showcase the new technology kit and other technical innovations for sustainable mobility at the IAA Mobility in Munich. The international automotive trade fair will take place from Sept. 4-10, 2023.

The MCT and SCT electric motor, are among the latest innovations from the Stuttgart-based automotive supplier in the field of electric drives. Dispensing with rare earths in MCT technology not only makes production more environmentally friendly, but also brings advantages in terms of costs and raw material security, the company said. The MCT electric motor is characterized by high durability because the necessary transmission of electric currents between the rotating and stationary parts inside the motor is contactless and thus wear-free. Therefore, the motor is maintenance-free and suitable for a wide range of applications, according to MAHLE.

With the SCT electric motor, the traction motor can operate at high power for an unlimited period of time. Mahle said this technology was made possible by a new cooling concept. Its integrated oil cooling not only makes the e-motor robust, but also allows the waste heat generated to be used in the vehicle’s overall system at the same time. The new e-motor has a small size and is light weight with a compact design. Mahle said this results in a material cost and weight advantage – a lighter motor requires less material in production and at the same time increases the possible payload in commercial vehicles.

MAHLE said the MCT electric motor shows high efficiency over a wide speed/torque range. The SCT electric motor, on the other hand, is designed to achieve the highest efficiencies at the optimized main operating points. Another strength of the SCT electric motor is its high continuous output, according to Mahle. This enables it to be used in electric vehicles of all kinds, even under very demanding conditions. Examples include driving an e-truck over mountain passes or repeated acceleration of a battery-electric passenger car.

These technologies can be found at the Mahle IAA booth at the Munich exhibition center (Summit) in Hall A2. In addition, the technology group is presenting its new automated positioning system for wireless charging in the testing area in Hall C2. Another demonstration vehicle allows visitors to experience what Mahle calls “perfect air quality” in the vehicle interior.

All of the company’s innovations can be experienced interactively on its virtual trade fair stand at starting end of August.
