Application and Research of Motor Speed-torque Electric Synchronization System

摘要: 針對(duì)連軋管機(jī)組電機(jī)速度和轉(zhuǎn)矩的電氣同步控制問題，探討了在滿足剛性負(fù)載、不完全剛性負(fù)載和非剛性負(fù)載工藝需求的情況下的各種電機(jī)速度和轉(zhuǎn)矩的電氣同步控制方案。分析認(rèn)為：Φ180 mm PQF 連軋管機(jī)組的負(fù)荷平衡情況是復(fù)雜并且多種多樣的，每一種情況都可能需要有不同的解決方案；通過電機(jī)速度和轉(zhuǎn)矩的電氣同步控制可以實(shí)現(xiàn)高精度、高質(zhì)量的鋼管生產(chǎn)設(shè)備的精密控制。

Abstract: Addressing the issue of control of motor speed-torque synchronization for the mandrel pipe mill,different schemes for motor speed-torque synchronization are discussed with consideration of satisfaction to different process requirements. i.e.,rigid load,incomplete load and non-rigid load. It is regarded via the analysis that the load balance statuses of the Φ180 mm PQF pipe mill are complicated and multiple,each may needs pinpointed solution scheme;and that it is possible to achieve hi-precision and hi-quality control of the steel pipe manufacturing equipment by means of the above mentioned motor speed- torque electric synchronous control.
