摘要: 针对异步电机实际运行时定子铁损会引起转子电流和转子磁通变化从而使原有电机模型不够精确的问题,推导出在α,β两相静止坐标系下考虑定子铁损影响因素的鼠笼式三相异步电机的动态数学模型,将Matlab/Simulink中的基本模块和S-function相结合,构建了考虑铁损影响的鼠笼式三相异步电动机的仿真模型.仿真结果表明,考虑铁损影响的异步电机模型能更加准确地反映电机实际运行特性.Abstract: The induction motor model not considering iron loss is not accurate,because the iron loss will affect the rotor current and rotor flux when the motor is running.The dynamic mathematical model of asynchronous motor considering iron loss in the two-phase(α,β) stationary reference frame was deduced.Using the basic module and S-function of Matlab/Simulink,the simulation model of three phase asynchronous motor with iron loss was built.The simulations demonstrate that the model with iron more accurately reflect the situation of running motors.
