摘要： 在工程实际中，电动机起动时引起的母线电压下降不能超过规定值．通过建立等值电路和公式推导，得出最大允许的额定起动容量的计算公式，进而确定在各种条件下允许起动的电动机的最大额定功率．分析了影响计算结果的各个因素及近似处理产生的误差．

Abstract: In practical projects，while an asynchronous motor starting，the drop of voltage on the bus bar must be within the lim its which is stipulated by the national standard． By establishing a equivalent circuit and mathem atics deduction，a form ula，by which we can calculate the largest rated starting capacity that permitted，was obtained．A nd on the basis of the result，the largest rated power of a motor that perm itted on a variety of conditions can be determined．M eanwhile，several factors that change the final result were discussed，as well as the error due to the approximation．
Key words: asynchronous motor    starting current    rated starting capacity    rated power
