摘　　要：本文建立了丰田Prius内置式永磁电机的二维仿真模型。采用磁路积分法,计算得到永磁体的漏磁系数。并且分析了不同电机拓扑结构对漏磁系数的影响。结果表明,减小气隙磁密、增大电机定子外径和提升永磁体厚度可以降低永磁体漏磁,提升永磁体利用率。A 2D simulation model of Toyota Prius built-in permanent magnet motor is established in this paper.Magnetic flux leakage coefficient can be calculated by integral equation method.And we also analyzed the influence of magnetic flux leakage coefficient various motor topologies.It turns out that declining magnetic flux leakage and improving the utilization rate of permanent magnet can be achieved by reducing the magnetic leakage and increasing outer diameter of motor stator and the thickness of permanent magnet.
