Abstract
Recently, the high power density and efficiency of interior permanent magnet synchronous motor (IPMSM) for electric vehicle traction has been attracting attention. Particularly in order to overcome the cost issues of rare-earth dependent on China, Magfine magnet, which consists of neodymium without Dysprosium (Dy) and has enhanced coercive force, has been developed. However, Magfine magnet is vulnerable to irreversible demagnetization by external magnetic field. And it is essential to prevent this phenomenon. This paper suggests a design using the magnetic flux barriers in order to decrease the irreversible demagnetization of the permanent magnet (PM). Also, by using the 2-D finite element analysis (2-D FEA), it was confirmed that the permanent magnet irreversible demagnetization characteristic of the proposed model is improved. Thus, when advancing research in consideration of the Magfine fabrication process, it is expected that the commercialization of Magfine magnet can be accelerated with a more accurate performance prediction.
