摘要
文章在SPWM型逆变器驱动感应电机仿真的基础上,分析了输出电压谐波分布的特点和幅值的变化规律。并对变频器供电下感应电机输出转矩进行了研究,得出了转矩脉动频率和谐波之间的关系。结果表明基于SPWM供电会产生较大的转矩脉动,影响电机运行性能。
According to the simulation of SPWM inverter-fed induction motor,this paper analyses the characteristic of output voltage harmonics and the law of magnitude changing and obtains the relationship between torque pulsating frequency and voltage harmonics,through studying the output torque.It shows that there is large torque pulsation which influences the performance of induction motor when motor is fed by SPWM.
