对机械设备的伤害
全压直接起动时的起动转矩大约为额定转矩的2倍，这么大的力矩突然加在静止的机械设备上，会加速齿轮磨损甚至打齿、加速皮带磨损甚至拉断皮带、加速风叶疲劳甚至折断风叶等等。
软起动的转矩不会超过额定转矩，上述弊端可以克服。
当采用减压起动时，上述危害只有程度的降低；当采用软起动时，上述危害几乎消失；独立变压器供电方式直接起动只能在电网电压波动方面有所缓解，而其它方面的危害都照样存在。
超大型电动机的价值都很高，在生产中也都起着核心作用。它的一点故障便会造成很大的经济损失，对它采用完善的保护是非常必要的。比如说对一台电机我们不能指望它的各处绝缘都是一致的，可能在某一点就有个薄弱环节，出厂试验时它能通过，但在长时间的冲击下这个薄弱环节会逐渐首先显露出来，使其寿命缩短。如果我们采取软起动，则可以大大延长电机的使用寿命，这两种方案哪一个合算呢？这是显而易见的。
