摘　　要：提出了基于磁化曲线的异步电机磁路饱和dqn模型。该模型的分析方法有别于传统的磁路饱和处理方法,它直接利用了磁化曲线来考虑磁路饱和对电机的影响。在对磁化曲线进行处理的基础上,推导了考虑磁路饱和时异步电机的电压、电磁转矩方程,给出了Matlab/Simulink仿真模型和结果。比较线性模型同试验结果,表明了该模型较之线性模型具有一定的改进。An asynchronous motor d-q-n model considering flux saturation and based on the magnetization curve is brought forward. The method employed in building saturation modal differentiates from other conventional ones, which applies directly the curve＇ s derivable function to build the motor voltages＇ equations and electrical torque equations. Meanwhile the motor＇s Matlab/Simulink model and its simulation results are given. By comparison with liner model and the actual experimental results it confirms the job of this paper is correct and proper.
