By combining multi-loop method (MLM) and finite element method (FEM) together, this paper puts forward the extended MLM-FEM-coupled model of induction motors, which possesses the prominent advantage being capable of accounting for not only the stator/rotor winding layout, the distributed capacitances of the stator winding to the ground, the ground method and the supply transformer parameters, but saturation, eddy, slotting and other nonlinearities. Naturally, the extended MLM-FEM-coupled model presented here has a more widely application foreground. Based on the extended MLM-FEM-coupled model, the dynamic simulation of a 2-pole, 3-phase, 50 Hz and 3 kW squirrel cage induction motor is completed, as well as related experiments. The simulation and experiment results are provided in this paper. The agreement between the simulation and experiment results demonstrates the validity of the extended MLM-FEM-coupled model of induction motors
