Considering the problem of over many current sensors used in fivephase permanent magnet synchronous motor control system, a new method of current reconstruction for fivephase permanent magnet synchronous motor was proposed. This method used only two current sensors to realize full acquisition of fivephase current, could effectively reduce the cost and complexity of the hardware circuit. The reconstruction precision and speed could meet the needs of fivephase permanent magnet synchronous motor control. Finally, the proposed method was validated in MATLAB. Results showed the correctness and effectiveness of the proposed method.
