摘要
提出了电机系统裕量评价指标,采集了首钢京唐480 t铸造起重机大车运行机构电机电流转矩等数据,计算了裕量评价指标,验证了该系统电机容量选型偏大。
The paper puts forward the margin evaluation index for the motor system. The data such as motor current and torque are collected for the travelling mechanism of 480 t ladle crane, and the margin evaluation index is calculated. It＇s shown that the selected motor of the system has relatively large capacity.
