Model of multiphase induction motor

Abstract

The six-phase induction motor with two similar stator three phase windings, shifted by 30 degrees in space and three phase winding in rotor is considered. Differential equations of this motor are presented and transformed to dq synchronous reference frame. Dynamic equivalent circuits for each component are presented. Transformed equations are expressed in matrix form and are solved by MATLAB software using Dormand-Prince (ode45) method. Transient characteristics of torque, speed and current of six-phase induction motor are calculated and discussed.
