Developing Sustainable Motors - Designing E-Motors Independent of Rare Earth Metals with Altair Solutions

Permanent magnet motors are widely used in the development of electric vehicles (EVs). However, these devices are based on expensive, hard-to-recycle rare earth materials. Wanting to explore new boundaries in electric motor design and production, Spin started a project focused on replacing rare earths materials in these motors. To develop a more sustainable motor without using rare earth-based permanent magnets while still ensuring efficiency and meeting performance targets, Spin needed a tool that allowed them to study, evaluate, and improve every possible aspect of the motor’s behavior and performance before building a prototype. Thanks to the Altair® HyperWorks® platform and its multiphysics analysis capabilities, the Spin team made significant progress in developing a new, highly efficient product: the synchronous reluctance motor.
