变位机修复工作中的问题分析

Mending Analysis of Rotating and Tiltable Welding Unit

通过对电机的电磁转矩和启动时间常数的计算，就变位机中用新电机换装旧电机时可能出现的负载是否匹配，控制电路是否满足要求等问题进行了分析和讨论。

Through the caculating of the magnetic forque and starting time,this paper discusses some aspects which involve whether the load could be matached and control system could satisty the demand when replacing old motors with new ones in rotating and tiltable welding unit.
