Winding Function Based Analytical Model of Squirrel Cage Induction Motor for Fault Diagnostics

In this paper, a detailed analytical model of a three-phase squirrel cage induction motor is derived. The geometrical parameters of the motor are considered and couple magnetic circuit theory is used for the calculation of inductances, resistances and other performance parameters. Although analytical models are not as accurate as numerical models, their lower calculation time makes them important in the field of performance analysis and fault diagnostics, particularly in hardware-in-the-loop environment and inverse problem theory implementation. The model is made general for any number of rotor bars even if they are not integral number per pole and stator geometry considering the end ring parameters, leakage inductances, slotting and end winding effects.
