A fault-tolerant direct torque control (DTC) strategy for six-phase symmetrical winding shifted-phase 60° permanent magnet synchronous motor with arbitrary two opened phases is proposed in this paper. First, the relationship between flux and electromagnetic torque based on the modified stator flux a...
