Abstract :
In this paper, a new direct torque control (DTC) algorithm for six phase induction machines (6PIM) when one phase is lost will be introduced. The machine has two sets of three phase windings spatially shifted by 60deg electrical degrees. A general decoupled model of the induction machine with up to four open phases is given. Fixed switching frequency and low torque ripple are obtained using this method. Simulation results show good dynamic and steady state performance. Experimental results are carried out to validate the proposed method.
