Rare-Earth-Free Electric Motors Technology Development

The source discusses a British startup named Advanced Electric Machines (AEM) that has secured a multi-million-euro agreement with a major automotive supplier. This agreement will accelerate the development and market arrival of their electric motors, which do not utilize rare-earth magnets, by the end of the decade. AEM's technology is attractive because it avoids the use of expensive, difficult-to-source rare-earth elements dominated by China, offering a more sustainable and cost-effective alternative. These motors, possibly asynchronous or separately excited synchronous motors, are described as more powerful, recyclable, and environmentally friendly compared to conventional permanent-magnet motors. Ultimately, AEM claims their magnet-free motors will outperform standard electric motors in terms of both production and operational performance.
