摘要
分析了一类极槽数相近的分数槽集中绕组嵌入式永磁同步(FCW—IPM)电机的极槽数配合选择依据,基于二维有限元法对该类电机的气隙磁场分布、反电动势、稳态转矩、定位力矩等电磁特性进行了计算和分析。提出了一种交直轴电流全解耦与冻结磁导率相结合的方法,详细分析了交叉耦合及定转子相对位置变化对电机交直轴电感的影响规律。设计并制造了一台额定功率为10kW的样机,样机实验结果验证了设计方法和理论分析的正确性,为该类电机在混合动力汽车驱动领域的进一步应用奠定了基础。
The criteria of the pole-slot numbers combination of the interior permanent magnet(IPM) synchronous machines with fractional-slot concentrated windings(FCW), which possess the approximate number of poles and slots is analyzed. Moreover, 2D finite element analysis(FEA) for the machine is carried out to investigate the distribution of the air-gap magnetic field, back electromotive force(EMF), steady torque and cogging torque. A new frozen permeability method, which decouples the direct axis and the quadrature axis currents completely, is presented to illustrate the variation of the direct axis and the quadrature axis inductance with both the cross saturation and the change of rotor position respectively. A 10kW prototype was designed and built for exemplification. Experimental results of the prototype are given to verify the design method and the theoretical analysis, which are helpful on further application in the driving area of the hybrid electric vehicles.
