Analysis of Three-phase Induction Machine With Balanced Condition And Unbalanced Condition

This paper introduced a three-phase induction machine direct and quadrature model with two open-circuit stator phases (default 3-phase induction machine). It is shown that the direct and quadrature model of the faulty machine has the same equation structure as a balanced 3-phase induction machine with a correct transformation. Simulations are performed to test the dynamic behavior of the 3-phase induction faulty machine, based on the proven model of the faulty induction machine. The model built for a defective three-phase induction machine can be immensely helpful to design a fault-tolerant drive system controller.
