摘要
永磁同步牵引电机具有体积小、功率密度大、过载能力强、效率和功率因数高等特点,而电抗参数对永磁同步牵引电机的设计以及电机运行时平衡恒转矩转折速度点与弱磁恒功率最高速度点的性能有较大影响。本文利用Ansoft有限元分析软件对永磁同步电动机的交直轴同步电抗进行了计算,得出了交直轴电抗参数随电机参数的变化曲线,并分析了电机参数对电抗参数的影响。
The permanent magnet （PM） synchronous traction motor has the features of small volume, high power density, high overloading ability, high efficient and power factor. Reactance parameters have great influence on the design of PM synchronous traction motor, the turning speed of equilibrium constant torque performance and the highest speed of field-weakening constant-power performance. Using the finite element analysis software Ansoft, the quadrature-direct （d-q） axis reactance parameters of PM synchronous motor were calculated, the curves of d-q axis reactance parameters with the change of motor parameters, and the effects of motor parameters on reactance parameters were analyzed.
