摘　　要：直流电动机因其优良的启动、调速和制动性能,在某些工业领域占有举足轻重的地位。文章研究了直流电动机串电阻起动方法,在直流电动机电枢绕组中串入电阻来降低起动电流和起动转矩。相比于电机直接起动,串电阻起动起动电流和起动转矩显著减低,而且成本又增加不多,在实际工农业生产中有广泛的应用。DC motor has an important position in certain industrial fields for its excellent start,speed regulation,and braking performance.This paper studies the starting method with series resistance for DC motor,and the reduction of starting current and starting torque by series connection of a resistance into the armature winding of DC motor.Compared with the direct starting of DC motor,the starting current and starting torque is significantly reduced for the starting method of series resistance,and the cost increase is less,so it has wide application in the actual industrial and agricultural production.
