Rare-earth permanent magnet motors, as energy-efficient motor products, are contributing to the realization of the "dual-carbon" goal. Rare-earth permanent magnet materials have high magnetic energy product, high coercivity and high stability, which makes rare-earth permanent magnet motors have advantages of high efficiency, high power density and low noise, etc. Compared with traditional motors, rare-earth permanent magnet motors have the advantages of high efficiency, high power density and low noise. Compared with traditional motors, rare earth permanent magnet motors can significantly reduce energy consumption and improve energy utilization efficiency. In new energy vehicles, wind power generation and other fields, the application of rare earth permanent magnet motors has achieved remarkable results, providing strong support for the realization of energy saving and emission reduction and sustainable development goals.
