【Abstract】 To fully develop the regulating effect of zero voltage vectors in inhibiting torque ripple,the regulating effect of zero voltage vectors on electromagnetic torque was analyzed systematically in various control parameters based on the direct torque control system of a permanent magnet synchronous motor,and the calculation results and function curves were provided.Test results show the intrinsic factors and reasons which affect the operating results of zero voltage vectors.The control idea and experimental test results of reducing the torque ripple through the unique regulating effect of zero voltage vectors were proposed.更多还原
