Space Vector Double Frame Field Oriented Control of Six Phase Induction Motors

Abstract: – In this paper a new rotor field orientation control of six phase induction machine is proposed. The machine has two three phase windings spatially shifted by 30 electrical degrees. The dynamic model of the machine is based on the three two dimensional orthogonal subspaces. The proposed method uses a simple estimator for identifying rotor flux and its orientation. To eliminate the extra harmonic currents of stator windings that produce losses, space vector PWM technique and double synchronous frame current controller is employed. The simulation results illustrate the validity and efficiency of the proposed method. Key-Words:- Six-phase induction machine; Vector control; Space voltage modulation
