當(dang)電(dian)機(ji)bai通過工頻(pin)(pin)直接(jie)du啟動時，它將會產生(sheng)7至8倍的(de)電(dian)機(ji)額(e)定(ding)電(dian)zhi流，這個(ge)電(dian)流值將大大增加電(dian)機(ji)繞組的(de)電(dian)應力并產生(sheng)熱(re)量，從而降(jiang)低電(dian)機(ji)的(de)壽命。而變(bian)頻(pin)(pin)調(diao)速(su)則(ze)可以在零(ling)速(su)零(ling)電(dian)壓啟動(也可適當(dang)加轉矩(ju)提升)。一旦頻(pin)(pin)率(lv)和電(dian)壓的(de)關(guan)系建立，西(xi)門子變(bian)頻(pin)(pin)器就可以按照V/F或矢量控西門子G150變頻器上電報警F30001維修技巧制方式帶動負載(zai)進行工作(zuo)。使用變頻(pin)調速(su)能充分降(jiang)低啟(qi)動電(dian)流，提高繞組承受力，用戶(hu)直接的好處就是電(dian)機(ji)的維護成(cheng)本將進一步(bu)降(jiang)低、電(dian)機(ji)的壽命則(ze)相(xiang)應(ying)增加。

啟(qi)動時需要的功率更低

電(dian)機(ji)(ji)(ji)功(gong)率與電(dian)流和電(dian)壓的乘積成正(zheng)比,那(nei)么通過工頻直(zhi)接啟動的電(dian)機(ji)(ji)(ji)消(xiao)耗(hao)的功(gong)率將大(da)(da)大(da)(da)高于變頻啟動所需要的功(gong)率。在一些工況下其配電(dian)系統已經(jing)達(da)到了極限，其直(zhi)接工頻啟動電(dian)機(ji)(ji)(ji)所產生(sheng)的電(dian)涌就會對同網上的其他用戶產生(sheng)嚴重的影響。如果采(cai)用變頻器(qi)進行(xing)電(dian)機(ji)(ji)(ji)起停,就不會產生(sheng)類似(si)的問題。
