DUAL TWO PHASE MODEL OF SIX PHASE INDUCTION MOTOR

Abstract

In the earlier works the three phase induction motor is replaced by its two phase equivalent by the phase transformation of unified machine theory [1]. This brings about a remarkable simplification in the mathematical form of the voltage equations of the machine. To derive the three phase to two phase transformation, magneto motive force distributions inside the machine is considered. On similar lines, six phase induction motor is replaced by dual two phase equivalent by dual two phase transformation C1, Both Stator & Rotor equations are transformed by the dual two phase transformation C1. Then the complete transformed Impedance Matrix is obtained. For normal conditions of operation and for most abnormal ones, zero sequence currents cannot flow. So, the zero sequence equations can conveniently be neglected. Finally, the voltage equations for the dual two phase wound rotor induction Motor with dual two phase rotor are obtained.
