摘　　要：唐钢高速线材厂轧钢生产线风冷运输辊道电动机采用变频调速控制,随着轧制速度的加快,0～50 Hz可调频率范围的转速,不能满足生产的要求,因此对电动机进行了扩大调速范围的技术改造。简要介绍了在技改中3种可行性方案,并说明了实施方案中,由无测速反馈方式改为测速反馈方式参数的设置及步骤。The air - cooled roll motor, installed in the high - speed wire factory of Tangshan Iron and Steel Company, uses transducer to control the speed, which with the range of 0 - 50 Hz can not fit the demand of production. Explains the major reasons of the enlargement of the speed adjustment ranges for the air- cooled roll motor and briefly introduces three feasible plans in which the settings and steps of converting not - speed-measure feedback to speed - measure feedback are detailed.
