Abstract

In this paper, a new direct torque control (DTC) algorithm for six phase induction machines (6PIM) will be introduced. The machine has two sets of three phase windings spatially shifted by 60 electrical degrees. This approach is based on deriving the voltage vectors in a synchronous frame rotating with the stator flux. It leads to a fixed switching frequency and low torque ripples. Simulation and experimental results show satisfactory performances and validate the proposed method.
