Abstract:

This paper proposes and compares two new fault-tolerant fractional-slot concentrated-winding interior permanent magnet (FTFSCW-IPM) motor open-end winding (OW) drive systems for electric vehicles. The proposed FTFSCW-IPM motors possess the merits of high efficiency, high power density, and strong fault-tolerant capacity. Also, to further improve the reliability of control system, an OW dual inverter drive system is adopted. Furthermore, to better and clearer illustrate the advantages and disadvantages of multiphase machine system, the comprehensive comparison of three-phase and five-phase FTFSCW-IPM motor OW drive systems is carried out from the perspective of motor design and control system. The topologies and the features of the proposed two FTFSCW-IPM motors are analyzed, and the static characteristics are investigated and compared by using the finite-element analysis (FEA). Then, the evaluation of their OW drive system performance is conducted and compared by the simulation based on the MATLAB/Simulink. Finally, the FEA and simulation results are validated by experiment on both prototypes.
