變頻(pin)(pin)器(qi)(qi)(qi)50Hz以(yi)上(shang)的(de)應(ying)用狀(zhuang)況：大家知(zhi)道，對一個(ge)特定的(de)電(dian)(dian)(dian)(dian)機(ji)(ji)來說，其(qi)額外電(dian)(dian)(dian)(dian)壓和(he)(he)額外電(dian)(dian)(dian)(dian)流(liu)是不(bu)變的(de)。如變頻(pin)(pin)器(qi)(qi)(qi)和(he)(he)電(dian)(dian)(dian)(dian)機(ji)(ji)額外值(zhi)都是：15kW/380V/30A，電(dian)(dian)(dian)(dian)機(ji)(ji)能(neng)夠工作在50Hz以(yi)上(shang)。當(dang)轉速為(wei)(wei)(wei)50Hz時，變頻(pin)(pin)器(qi)(qi)(qi)的(de)輸出電(dian)(dian)(dian)(dian)壓為(wei)(wei)(wei)380V，電(dian)(dian)(dian)(dian)流(liu)為(wei)(wei)(wei)30A。這(zhe)時假如增(zeng)大輸出頻(pin)(pin)率(lv)到60Hz，變頻(pin)(pin)器(qi)(qi)(qi)的(de)比較大輸出電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流(liu)還(huan)只(zhi)能(neng)為(wei)(wei)(wei)380V/30A，很顯然輸出功率(lv)不(bu)變.所以(yi)咱們(men)稱之為(wei)(wei)(wei)恒功率(lv)調速。這(zhe)時的(de)轉矩狀(zhuang)況怎(zen)樣呢(ni)?因(yin)(yin)為(wei)(wei)(wei)P=wT(w：角(jiao)速度,T：轉矩)。因(yin)(yin)為(wei)(wei)(wei)P不(bu)變,w增(zeng)加了,所以(yi)轉矩會相(xiang)(xiang)應(ying)減(jian)(jian)小。咱們(men)還(huan)能(neng)夠再換一個(ge)視點來看：電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)定子(zi)電(dian)(dian)(dian)(dian)壓U=E+IR(I為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)流(liu)，R為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)阻,E為(wei)(wei)(wei)感(gan)應(ying)電(dian)(dian)(dian)(dian)勢)能(neng)夠看出，U、I不(bu)變時，E也不(bu)變。而E=kfX,(k:常數(shu),f:頻(pin)(pin)率(lv),X:磁通(tong))，所以(yi)當(dang)f由50-->60Hz時,X會相(xiang)(xiang)應(ying)減(jian)(jian)小對于電(dian)(dian)(dian)(dian)機(ji)(ji)來說，T=KIX(K：常數(shu)，I：電(dian)(dian)(dian)(dian)流(liu)，X：磁通(tong))，因(yin)(yin)此(ci)轉矩T會跟著磁通(tong)X減(jian)(jian)小而減(jian)(jian)小。高壓軟啟(qi)動(dong)器(qi)(qi)(qi)控(kong)制器(qi)(qi)(qi)售(shou)后上(shang)門維修聯(lian)系方式(shi)。白銀在線軟啟(qi)動(dong)器(qi)(qi)(qi)控(kong)制器(qi)(qi)(qi)售(shou)后維修電(dian)(dian)(dian)(dian)話
