社会发展是有阶段性的。在不同阶段，人们的生产手段、生产工具和生活用品都有很大的不同。上世纪80～90年代，我国的经济实力尚较薄弱，当时的小水泥和小钢铁发展很快，1000kW～4000kW电机的应用增长很快，与当时的经济基础相适应的液态起动装置出现，它经济实用，解决了电机起动中的一些问题。对当时的经济发展起到了的作用。到世纪之交时期，我国经济实力已有较大的发展，生产手段和生产工具亦有了较大发展，电机容量也有了很大增长，人们开始不满足液态起动装置的低性能，于是晶闸管串联式（固态）软起动装置的应用开始增加，继而又出现了开关变压器式软起动装置和磁饱和电抗器式（磁控）起动装置，变频装置用于电机软起动的情况也越来越多，当前这四种产品是大型电机起动市场的主流产品，液态起动装置则应用在小型（5000kW以下）电机上较多。另外，两种老式起动方法（自耦变压器和变压器-电动机组）也常常出现在20000kW以下电机的起动上。
大型电机驱动的设备一般都是企业的核心设备，直接影响企业的生产状况，因此人们应该对其起动给予特别的关注，合理的选择起动装置将给企业带来很大的经济效益。但是电机起动技术毕竟不是一个企业的核心技术，许多企业的电气工作者很少有时间来研究起动方法之间的差别，往往会造成不恰当的选择，有时甚至不得不做出第二次选择，给企业造成不应有的损失。因此，如实地说明起动方法的性能及其差别是非常重要的。
电动机直接全压起动的危害性及软起动好处
⒈ 引起电网电压波动，影响同电网其它设备的运行
交流电动机在全压直接起动时，起动电流会达到额定电流的4~7倍，当电机的容量相对较大时，该起动电流会引起电网电压的急剧下降，影响同电网其它设备的正常运行。
软起动时，起动电流一般为额定电流的2~3倍，电网电压波动率一般在10%以内，对其它设备的影响非常小。
