摘　　要：感应子电机因其转子结构简单,具有非常高的可靠性,特别适用于高速场合,在脉冲电源、储能系统、航空发电、船舶推进系统等领域有着广泛的应用。感应子电机的磁场为三维磁场,但三维磁场分析所需计算资源和时间太多。因此,对感应子电机的磁场分析一般采用简化二维模型。目前,感应子电机二维磁场计算模型主要有:标量磁位法、矢量磁位法、等效励磁绕组法和改进等效励磁绕组法四种模型。标量磁位法、矢量磁位法、等效励磁绕组法和改进等效励磁绕组法各有优缺点,本文对以上四种二维磁场计算模型进行了对比研究,分析了各自的优缺点,对其适用性进行了讨论。Because of its simple rotor structure,the homopolar inductor alternator(HIA)has very high reliability,especially suitable for high-speed applications,in the pulse power supply,energy storage system,aviation power generation,marine propulsion system and other fields have a wide range of applications.The magnetic field of HIA is 3D magnetic field,but the computing resources and time required for 3D magnetic field analysis are too much.Therefore,a simplified two-dimensional model is generally used to analyze the magnetic field of HIA.At present,there are four kinds of two-dimensional magnetic field calculation models of HIA:scalar magnetic potential method,vector magnetic potential method,equivalent excitation winding method and improved equivalent excitation winding method.Scalar magnetic potential method,vector magnetic potential method,equivalent excitation winding method and improved equivalent excitation winding method have their advantages and disadvantages.In this paper,the above four two-dimensional magnetic field calculation models were compared,their advantages and disadvantages were analyzed,and their applicability was discussed.
