摘　　要：详细分析了低压异步电动机常用的几种起动方法,介绍了异步电动机全压起动时压降的计算方法,对异步电动机的起动方式选择进行分析,以具体工程为例,分析讨论不同场合、不同功率异步电动机起动方式,确定电动机最优起动方式。Several commonly used starting methods of low-voltage asynchronous motors were analyzed in detail, voltage-drop calculation method of asynchronous motor at full-voltage starting was introduced and starting methods selection of asynchronous motors were analyzed. Taken specific project as example, starting methods of asynchronous motors in different occasions and with different power were discussed to determine the optimal starting method of motors.
