摘　　要：电磁选针器的响应速度和能耗是关系大针数电子提花机性能的两个重要因素。从理论上分析了电磁铁吸合的过程,讨论了两种常见的加速电磁铁快速响应的方法,在此基础上设计了一种基于电流控制的提花机选针器驱动电路,给出了驱动电路平均电流的计算方法。实验结果表明,该电流控制方法能使电磁铁在吸合阶段实现高电流快速有效吸合,在保持阶段实现低电流低功耗保持。The response speed and energy consumption of electromagnetic needle selector are two important factors concerning the performance of electronic jacquard machine with high number of threads. This paper theoretically analyzes the process of electromagnet actuation,discusses two common methods of accelerating rapid response of electromagnet,designs a driving circuit of needle selector of jacquard machine based on current control on this basis and gives the computing method of average current of driving circuit.The experimental result shows that this current control method can make electromagnet realize high-current,rapid and effective actuation in actuation stage and realize the maintenance of low current and low energy consumption in the stage of maintenance.
