Simulation and Research of Induction Motor Considering Iron Loss in Stationary Reference Frame

Based on mathematical analysis, the dynamic mathematical model of asynchronous motor with iron loss and the model without iron loss are deduced. Using the basic modules and S-function of MATLAB/SIMULINK, the simulation models of three phase asynchronous motor with iron loss and without iron loss are built. Compare the two models with the results of simulations, and give the influence on stator current, flux rotor speed, torque, under the condition of increasing load. The simulations demonstrate that the model with iron reflects the situation of running motors more accurate.
