摘　　要：针对混合动力汽车用同步电机,其内部的电刷和滑环带来电接触的劣势不可避免。本文提出一种新型励磁系统,它无需电刷和滑环,称为非接触励磁系统(CES)。相对旋转部分和相对静止部分同时存在于变压器中。设计毗连型和嵌套型两种针对CES的变压器绕制拓扑进行研究。通过模型建立确定了两种拓扑的最优工作气隙。毗连型和嵌套型绕制拓扑均可以较为快速地建立起耦合磁场,毗连型绕制拓扑磁感应强度建立情况优于嵌套型绕制拓扑。最后样机得到相应的传输性能和效率参数,并进行详细分析。实验结果进一步验证了毗连型绕制拓扑对CES系统更加合理,对进一步完善非接触式励磁系统起到关键性作用,设计的CES将对混合动力汽车同步电机励磁提出一种新的思路。Synchronous motorsare being widely used in hybrid electric vehicle industry,and the electric contact disadvantages which are caused by its interior contained brush and slip ring structure are inevitable.Aiming at this,put forward a new excitation system without brush and slip ring structure and name it contactless excitation system(CES).Relative rotating part and relative stationary partcoexisted in a transformerwith special working characteristics.Adjacent winding and coaxial winding topologies are designed aiming at the CES transformer winding topology.The system theoretical derivation,topology modeling,contrast simulations and contrast experimental studies were conducted respectively.The optimum operating air gap of two types of topologies were confirmed through the construction of Ansoft model.Meanwhile,the adjacent winding topology magnetic lines of force closure degree being better than that of the coaxial typewinding topology was verified.The adjacent winding topology and coaxial winding topology can both set up the coupling magnetic field relatively quickly.The magnetic induction setting up circumstance of adjacent winding topology was better than coaxial winding topology.The experimental prototypes of adjacent winding topology and coaxial winding topology are set up and the transmission performance and efficiency parameters were obtained.Detailed analysis was conducted at the same time.The experimental results further verify the rationality and accuracy of adjacent winding topology for CES,and plays a key role in the future improvement of CES.
