【摘要】 论述了复卷机电气控制采用交流变频的传动方式,以专用变频器为执行单元控制交流异步机,摒弃传统的直流传动调速方式,解决了张力恒定要求下退纸辊大范围调速的技术难题,达到了较高的性能价格比。更多还原

【Abstract】 The paper describes the rewinder’s electric control system with AC in which a converter is used to control AC motor. It discards the conventional speed adjustment with variable frequency drive and solves the technology problem of wide range speed adjustment of the discharging roll under consistent tension. It achieves a better rate of performance to the cost.更多还原
