當電(dian)機通(tong)過工頻直接(jie)啟動時，它將會產生7至8倍的電(dian)機額定電流，這個電流值將大(da)(da)大(da)(da)增(zeng)加(jia)電機(ji)繞組(zu)的電應力并產生熱(re)量(liang)，從而降低電機(ji)的壽命。而變(bian)頻調速則可以在(zai)零速零電壓啟動(也(ye)可適(shi)當(dang)加(jia)轉(zhuan)矩提升)。一旦(dan)頻率和電壓的關系建立(li)，西門子變頻器就可以按(an)照V/F或矢量控制方式帶動負載進行工作。使用變頻調(diao)速能充分降低啟動電流，提高繞組承受力，用(yong)戶直(zhi)接的好(hao)處就是電機的維(wei)護成(cheng)本將進(jin)一步降(jiang)低、電機的壽命則相應增加。
　　二、啟動時(shi)需要的功率更(geng)低
　　電(dian)(dian)(dian)(dian)機功(gong)(gong)率與電(dian)(dian)(dian)(dian)流和電(dian)(dian)(dian)(dian)壓的(de)(de)乘(cheng)積成正比(bi),那么通過(guo)工(gong)(gong)頻直(zhi)接啟動(dong)(dong)的(de)(de)電(dian)(dian)(dian)(dian)機消耗的(de)(de)功(gong)(gong)率將(jiang)大大高于變頻啟動(dong)(dong)所(suo)需要的(de)(de)功(gong)(gong)率。在(zai)一些工(gong)(gong)況下(xia)其(qi)配電(dian)(dian)(dian)(dian)系(xi)統已(yi)經達到了(le)極限，其(qi)直(zhi)接工(gong)(gong)頻啟動(dong)(dong)電(dian)(dian)(dian)(dian)機所(suo)產(chan)(chan)生的(de)(de)電(dian)(dian)(dian)(dian)涌(yong)就(jiu)會對同(tong)網上的(de)(de)其(qi)他用戶產(chan)(chan)生嚴重的(de)(de)影響。如果(guo)采(cai)用變頻器(qi)進行電(dian)(dian)(dian)(dian)機起停(ting),就(jiu)不會產(chan)(chan)生類(lei)似(si)的(de)(de)問(wen)題。
