In most cases, simulation of induction machines under dynamic conditions have been based on two-phase models using constant circuit parameters. Squirrel cage induction machines with double rotor bars which are made for high starting torgue have lower rotor bars of sufficient depth they cannot be accurately represented by a constant rotor resistance under all operating condition. In this paper, the circuit of three-phase symmetrical induction machines is represented in two-axis model by tensor. A method for simulating three-phase squirrel cage induction machines in a dynamic conditions is presented, and the current distribution in double rotor bars is calculated under dynamic conditions.
