| 摘 要： | 考虑到起动过程中饱和、谐波及随转速变化的挤流效应等因素对转矩曲线的影响,研究如何从瞬态转矩曲线获取最小转矩数值.首先采用场-路-运动耦合的时步有限元方法得到起动过程的瞬态转矩转速曲线,为了从所获得的转矩随时间以及随转速变化呈现出急剧波动的曲线获得最小转矩的数值,提出了新的数据处理方法,使用该方法经过一次计算即可得最小转...

| Abstract: | This paper discusses how to obtain the minimal torque value of line-start permanent magnet synchronous motor(LSPMSM) starting process considering the saturation,harmonic and skin effect on the impact of torque curve.Firstly the starting process speed-torque curve was obtained using field-circle-motion coupled time-stepping finite element method.In order to obtain the minimal torque value from rapidly fluctuating curves which torque versus speed or time,this paper presented a novel data processing method,usi... |
