Simulation of Polyphase Induction Machines with Deep Rotor Bars

Abstract
Simulations of induction machines under dynamic conditions have heretofore been based on two-phase models using constant circuit parameters. Most induction motors in the integral horsepower sizes have rotor bars of sufficient depth that they cannot be accurately represented by a constant rotor resistance under all operating conditions A method for incorporating the rotor deep-bar effect in a dynamic simulation is presented.
