The Perfect Motor By MAHLE

MAHLE, a global automotive supplier based in Stuttgart, has developed a groundbreaking technology kit for electric motors, which it refers to as the "perfect motor."

This innovative motor combines the benefits of the company's benchmark SCT (Superior Continuous Torque) and MCT (Magnet-free Contactless Transmitter) electric motors, delivering permanently high peak power, contactless and wear-free power transmission, absence of rare earth materials, and maximum efficiency.

Arnd Franz, Chairman of the MAHLE Group Management Board and CEO, emphasized that this technology toolbox enables MAHLE to provide tailored electrification solutions for various vehicle classes, applications, and brand philosophies.

This initiative is part of MAHLE's 2030+ Group strategy, focusing on electrification, thermal management, and highly efficient green combustion engines.

The company will showcase its new technology kit and other sustainable mobility innovations at the IAA Mobility in Munich, an international automotive trade fair, from September 4 to 10, 2023.

The MCT and SCT electric motors, which operate without contact and rare earth materials, are the latest electric drive innovations from MAHLE.

Eliminating rare earths in MCT technology makes production more environmentally friendly while also offering cost and raw material security benefits.

The MCT electric motor is particularly efficient at almost all operating points, demonstrating its full efficiency advantages in areas frequently encountered in real road traffic.

Additionally, the MCT electric motor features high durability due to its contactless and wear-free transmission of electric currents between rotating and stationary parts inside the motor, making it maintenance-free and suitable for various applications.

On the other hand, the SCT electric motor is currently the most enduring electric motor in MAHLE's portfolio.

The traction motor can operate at high power indefinitely, thanks to a new cooling concept involving innovative integrated oil cooling.

This not only makes the e-motor robust but also enables the utilization of waste heat generated in the vehicle's overall system.

The new e-motor stands out for its small size, light weight, and efficiency, resulting in material cost and weight advantages, which in turn increase the potential payload in commercial vehicles.

The MCT electric motor exhibits high efficiency across a broad speed/torque range, whereas the SCT electric motor is engineered to achieve maximum efficiencies at optimized main operating points.

Another notable feature of the SCT electric motor is its high continuous output, which ranges from 93 to 100 percent of its peak power, as proven by measurement results.

This unparalleled high ratio, unique in the market, makes it suitable for use in electric vehicles of all types, even under extremely demanding conditions, such as driving an e-truck over mountain passes or repeatedly accelerating a battery-electric passenger car.

MAHLE at IAA Mobility 2023 Visitors to the MAHLE booth at the Munich exhibition center (Summit) in Hall A2 can also experience the company's new automated positioning system for wireless charging in the Testing Area in Hall C2.

Additionally, a demonstrator vehicle will allow visitors to experience optimal air quality inside the vehicle.

Another highlight is the AI comfort demonstrator, which showcases how artificial intelligence can enhance vehicle interior comfort in the future. Moreover, MAHLE will present its E-HEALTH Charge system, which enables optimal examination, assessment, and simultaneous charging of sensitive lithium-ion batteries in workshops.
