电动机起动时母线电压及端电压的验算是保证电动机、照明、电气设备正常运行的必要设计步骤，也是电气设计计算的难点。相关设计手册给出的电动机起动时母线电压及端电压的计算公式，笔者经过推演发现有的公式表达不完整或有错误，故重新推导了电动机全压起动及带电抗器起动时，母线电压相对值及电动机端电压相对值计算公式。
電動機起動時母線電壓及耑電壓的驗算是保證電動機、照明、電氣設備正常運行的必要設計步驟，也是電氣設計計算的難點。相關設計手冊給齣的電動機起動時母線電壓及耑電壓的計算公式，筆者經過推縯髮現有的公式錶達不完整或有錯誤，故重新推導瞭電動機全壓起動及帶電抗器起動時，母線電壓相對值及電動機耑電壓相對值計算公式。

Checking calculation of bus and terminal voltages, also the difficult point in electric design, is required during the motor starting in order to ensure the normal operation of motor, lighting and electric equipment. The author found out that the calculation formula provided in related design manual is incomplete or incorrect, so the author induces again the formula for calculating the relative values of the bus and terminal voltages when the motor starts in full voltage and with electric reactor.
