Fault simulation of squirrel cage induction motor based on winding function

Simulation is an important way of fault study, and its effect is related to the veracity of model parameters. There are parameters of inductance in the simulative model of squirrel cage induction motor,which can be precisely calculated using winding function. Based on that,mathematical models of squirrel cage induction motor in normal and familiar fault conditions,such as turn-to-turn fault of stator,broken bar fault of rotor and gap eccentricity,are established and simulated. Simulative results coincide with the theoretical concludes,which shows the correctness of the models and the parameter calculation. It provides support to fault diagnosis.
