分段供电六相圆筒式直线感应电动机数学模型

为研究新型分段供电六相圆筒式直线感应电动机的运行规律，针对其不对称运行的特点，采用磁动势理论推导了气隙中与空间位置无关的脉振磁场的电感矩阵表达式，通过将其引入abc坐标系下对称的电机数学模型，从而构建描述六相圆筒式直线感应电机不对称的数学模型。在Simulink环境下，采用隐式梯形法构建该不对称模型的系统仿真模型。对样机进行仿真分析和实验验证，仿真结果与实验数据吻合良好，验证了模型的正确性。
In order to investigate the law of asymmetric operation of six phase cylindrical linear induction motor and in the view of its characteristics of asymmetric operation， the magnetic motive force theory was used to deduce inductance matrix expression of pulsating magnetic field which is independent of the space position in the air gap,. The mathematical models of SCLIM in abc stationary and system simulation models which adopted the implicit trapezoidal rule were established under the Simulink environment. Simulation and experimental results of a SCLIM agree well with each other, which verifies the validity of the proposed model.
