InfiMotion’s magnesium-aluminum alloy dual motor assembly claims 25% weight reduction over aluminum

InfiMotion has unveiled a pioneering dual motor assembly featuring a magnesium-aluminum alloy housing, which it claims is the first of its kind to be mass-produced. This innovative design achieves a significant 25% reduction in weight compared to traditional aluminium alloy housings, while still maintaining the necessary structural strength for production vehicles. The company is presenting this alongside other advanced electric drive products at the 5th International Forum on Automotive Power Systems in Shanghai. A key aspect of the new dual motor assembly is its thermal management system, which utilises InfiMotion’s proprietary 360° bidirectional full oil cooling technology. This approach ensures efficient heat dissipation, supporting the motor’s performance and reliability under demanding conditions. The magnesium-aluminum alloy not only contributes to weight savings but also works in tandem with the cooling system to maintain optimal operating temperatures. InfiMotion is also showcasing three additional products that highlight its focus on efficiency and high performance. One is a magnetic field-adjustable motor designed to reduce no-load drag losses by varying the magnetic flux according to driving conditions, thereby lowering energy consumption. Another is an ultra-high-speed motor capable of reaching 36,000 rpm, aimed at high-performance electric vehicle applications. Lastly, a 9-in-1 integrated e-drive controller consolidates multiple power electronics and vehicle control functions into a single compact unit, streamlining system architecture. These developments underscore InfiMotion’s commitment to advancing electric drive technologies with an emphasis on weight reduction, efficiency, and integration. The magnesium-aluminum alloy dual motor assembly, in particular, could have significant implications for electric vehicle design by improving powertrain efficiency and overall vehicle dynamics. As the industry continues to prioritise lightweight materials and sophisticated thermal management, InfiMotion’s innovations may set new benchmarks for electric motor assemblies in production EVs.
