对电网的影响主要表现在两个方面：
①超大型电机直接起动的大电流对电网的冲击几乎类似于三相短路对电网的冲击，常常会引发功率振荡，使电网失去稳定。
②起动电流中含有大量的高次谐波，会与电网电路参数引起高频谐振，造成继电保护误动作、自动控制失灵等故障。
软起动时起动电流大幅度降低，以上影响可免除。
⒊ 伤害电机绝缘，降低电机寿命
①大电流产生的焦耳热反复作用于导线外绝缘，使绝缘加速老化、寿命降低。
②大电流产生的机械力使导线相互摩擦，降低绝缘寿命。
③高压开关合闸时触头的抖动现象会在电机定子绕组上产生操作过电压，有时会达到外加电压的5倍以上，这样高的过电压会对电机绝缘造成伤害。
软起动时，大电流降低一半左右，瞬间发热量仅为直起的1/4左右，绝缘寿命会大大延长；软起时电机端电压可以从零起调，可免除过电压伤害。
⒋电动力对电机的伤害
大电流在电机定子线圈和转子鼠笼条上产生很大的冲击力，会造成夹紧松动、线圈变形、鼠笼条断裂等故障。
软起动时，由于大电流小，则冲击力大大减轻。
