Abstract :
This work has developed a steady-state and dynamic mathematical model of three phase slip-ring induction motors with external impedance. Differential equations are solved using computer simulation and data for an induction machine are obtained from laboratory tests. It is shown that harmonics due to impedance asymmetry produce changes on the electromagnetic torque and induce harmonic frequency currents in the stator windings
