摘　　要：电动机启动设计问题因涉及面广、专业性强而成为电气专业人员常研究的课题。结合具体工程实践,参照国家标准及相关设计手册,利用科学计算软件,对某闸门启闭机电动机启动设计进行分析,侧重点在于电动机启动平均电流的计算及电动机选型。探讨了绕线转子异步电动机启动平均电流工程计算方法,分析计算了启动平均电流及启动时间与转子所串电阻的关系,所得结论与实际运行数据相符。Motor starting design problems due to the wide range, strong professional often become electrical professionals research topic. Combining with specific engineering practice, referencing to national standards and related design manual, using scientific computing software, a gate hoist starting design analysis was offered, focus lies in the motor starting average current calculation and motor selection, discussed the wound rotor asynchronous motor starting average current engineering calculation method , analysed the starting average current and starting time series with rotor resistance, the conclusion is consistent with the actual operation data. Because technology continues to progress, and the specific problems need concrete analysis, the design experience and related conclusion is only for the colleague reference.
