MagHEM is developing high performance magnet beyond a conventional Nd-Fe-B magnet and motor evaluation technology when using new magnet.
Targets of R&D are new magnets exceeding Neodymium magnets with 2 times in (BH)max (180℃), and high efficiency motors with 40% reduction in loss, 40% improvement in power density using new magnets.
This time, it’s introduced about an analysis of a motor using JMAG including the efficiency map of the IPM motor using high performance magnet.
This article is based on results obtained from the Future Pioneering Program “Development of magnetic material technology for high-efficiency motors” commissioned by the New Energy and Industrial Technology Development Organization (NEDO).
