Rare earth permanent magnets have significantly enhanced performance of permanent magnet motors and made it widely served in every area. Most of these rare earth permanent magnets are belonging to 네오디뮴 자석 which have relatively high coercivity, remanence, electrical resistivity, and low heat resistance. Eddy current loss of the 네오디뮴 자석 대부분의 경우 구리 손실 및 철 손실에 비해 상대적으로 낮습니다. 고속 모터 및 고출력 밀도 모터의 경우, 와전류 손실 네오디뮴 자석 will result in rotor temperature rise and irreversible demagnetization would take place in the 네오디뮴 자석, then further affect motor performance. Laminated Neodymium magnets made by magnet segmentation solution are a practical solution to find a balance between the trade-off between power and heat without changing composition of magnet, motor’s structure and performance. Laminated Neodymium magnets are mainly served to 축 플럭스 모터 항공기, 모터 스포츠 및 자동차에서.
