5.1.提高了产量。虽然在小纱和大纱时降低了5％-8％的速度（目的是降低断头

5.2.提高了产品质量。利用变频器控制速度波动小，从而降低断头率，因断头的减少挡车工可以将节省的时间用来作清洁工作减少了许多突发的纱疵，提高了产品质量。
5.3.节约原料。断头减少后接头回花减少，皮辊花也相应减少，也就是节约了返工浪费的原料。
5.4.更改工艺方便。自动化程度提高，降低劳动强度更换品种或调节转速时，不需更换皮带盘，直接修改变频器参数就可以实现。
5.5.对某些纺纱有一定难度的品种如强捻纱、包芯纱、麻棉纱及高档精梳产品，通过变速选择生产过程点，可最大程度提高单产、减少断头。
5.6.采用变频器+异步电机的驱动方式，可最大潜力挖掘电机的无功功率，充分利用和提高功率因数，从而达到节电的目的。细纱机功率因数从原来的0.71提高至0.92降低了无功电流，降低了线路损耗，节省了电能。
5.7.细纱断头减少，值车工可以增加看台数、减少了用工数量、节约了人力成本。
5.8.设备故障率降低，减少设备故障造成的停工停产的损失，相对提高了产量，降低设备维护成本。
