N2 - A novel equal-magnitude sinusoidal current compensation strategy is proposed for fault-tolerant control of symmetrical six-phase PMSM with one-phase open-circuit fault. Rotating rhombus method (RRM) is proposed for the derivation of compensation currents, based on describing fault-tolerant currents with rhombuses in the vector diagram. The proposed strategy is validated by a 12-slot/l4-pole symmetrical six-phase PMSM using finite element analysis (FEA), and proved to be effective to improve machine performance under fault-tolerant condition. Two existing compensation strategies are compared with the proposed strategy from the aspects of torque, torque ripple, unbalanced magnetic pull (UMP), losses, and efficiency. Besides, implemental difficulty and the copper loss distribution of stator windings are evaluated among different strategies, and the proposed strategy is proved to have the advantages of lower implemental difficulty and balance copper loss distribution.
