Designing for Circularity in EV Motors
Designing EV motors with circularity in mind is crucial for minimizing environmental impact and maximizing resource recovery. By incorporating design principles that facilitate disassembly, recycling, and reuse, we can create a more sustainable future for electric mobility.
Modular Design
A modular design approach breaks down the EV motor into smaller, independent units. This simplifies disassembly and enables the replacement of individual components instead of replacing the entire motor. For example, the stator, rotor, and bearings can be designed as separate modules, allowing for easy access and replacement.
