Abstract :
A method for predicting the steady state performance of a solid rotor induction motor using coupled non-linear complex finite elements is described. The principle of the model is to consider two starting times, ω in the stator region and sω in the rotor region. The coupling between the rotor and the stator is achieved by two means using Lagrange multipliers at a suitable air-gap interface. A comparison between the experimental and the computed characteristics of a solid rotor induction motor is performed with interesting results.
