【摘要】：作为混合动力车中的电气无级变速器,复合结构永磁电机具有使内燃机独立于路况负载运行于高效率区、提高燃油经济性、降低排放等优点。主要针对混合动力车用新型复合结构永磁电机中的磁场耦合问题展开研究。首先将混合动力车用永磁电机与丰田Prius系列混合动力车中的丰田混合动力系统(THS)进行参数匹配,得到复合结构永磁电机的设计参数,并使二者具有相同的动力驱动性能;然后建立复合结构永磁电机的内部等值磁路模型,并以此为基础探索复合结构永磁电机内部磁场耦合规律;最后,利用2D-Ansoft有限元软件仿真分析复合结构永磁电机在不同工作模式下的内部磁场分布,并提出其内部磁场解耦设计方案,为复合结构永磁电机在混合动力车中的进一步应用奠定理论基础。
[Abstract]:As the electric stepless transmission in the hybrid electric vehicle, the composite structure permanent magnet motor can make the internal combustion engine run in the high efficiency zone independently of the road load, and improve the fuel economy. The magnetic field coupling problem in a new hybrid structure permanent magnet motor for hybrid vehicle is studied. Firstly, the hybrid permanent magnet motor and Toyota Prius series hybrid electric vehicle are introduced. Toyota hybrid power system (. The parameters were matched by THSs. The design parameters of the composite structure permanent magnet motor are obtained, and they have the same driving performance. Then the internal equivalent magnetic circuit model of the composite structure permanent magnet motor is established and the coupling law of the magnetic field inside the composite structure permanent magnet motor is explored. Finally, using 2D-Ansoft finite element software to simulate the internal magnetic field distribution of the composite structure permanent magnet motor under different working modes, and put forward its internal magnetic field decoupling design scheme. It lays a theoretical foundation for the further application of composite structure permanent magnet motor in hybrid electric vehicle.
