- Furthermore , this dissertation also gives a comprehensive analysis and comparison to the torque ripple factor , torque - current ratio and other aspects for pseudo - sinusoidal emf bldcm drived by 120 conduction mode , 180 conduction mode and self - synchronous svpwm mode respectively . the simulation and the experimental results indicate that self - synchronous svpwm method is more effective for minimizing the torque ripple without any expense of the torque - current ratio when the crest width of the back - emf waveform is less than 107 electrical angles
对准正弦波反电动势无刷直流电动机在120导通方式、 180导通方式和自同步svpwm三种控制方式下的转矩脉动系数、转矩电流比等方面进行了全面的分析与比较，仿真研究和实验结果表明，当反电动势的平顶宽度小于107电角时，采用自同步svpwm控制方法可以在不损失转矩电流比的基础上，更有效地抑制电磁转矩脉动。 - In this paper , on the basis of the analysis of gear pimp working principle , the mechanism of flow pulsation and methods of reducing flow pulsation are pulsation are studied . the computing formula of transient flow rate and the coefficient of flow pulsation are deduced . the relationship between the gear pump flow pulsation and the construction parameters of the gear is studied
