本文对内置式永磁(IPM)电机的新型转子结构进行了精确的分析，强调了如何设计磁阻以提高电机的性能。为此，通过有限元分析研究了转子中的磁场，发现对于这种类型的电机来说，这种分析特别准确。将经典IPM电机的参数(永磁磁链和d、q轴电感)和性能(转矩-速度特性)与新设计的相同参数进行了比较。
In this paper, the new rotor structure of an interior permanent magnet (IPM) motor is accurately examined, highlighting how flux-barriers have to be designed to improve the motor performance. To this aim, the magnetic field in the rotor has been studied by a finite element analysis, that has been found to be particularly accurate for this type of motor. The parameters (PM flux linkage and d- and q-axis inductances) and the performance (torque-speed characteristic) of a classical IPM motor are compared with the same items of the novel design.
