上海(hai)恒稅修西(xi)門(men)(men)子(zi)(zi)工業(ye)(ye)設備(bei)修的(de)好還修的(de)快(kuai)，我(wo)公司(si)庫存各系列西(xi)門(men)(men)子(zi)(zi)配(pei)件(jian)(jian)及(ji)維(wei)修所需配(pei)件(jian)(jian)，模(mo)塊，電(dian)容，芯片等核心配(pei)件(jian)(jian)都是原廠，修好不易壞，很多(duo)修好用(yong)(yong)到(dao)報廢都有。如果需要維(wei)修可(ke)(ke)以(yi)發給我(wo)公司(si)處(chu)理(li)，另(ling)外公司(si)各西(xi)門(men)(men)子(zi)(zi)模(mo)擬(ni)測試(shi)平臺等在(zai)線測速儀都齊全(quan)，在(zai)加上專業(ye)(ye)的(de)西(xi)門(men)(men)子(zi)(zi)維(wei)修團隊(dui)，可(ke)(ke)以(yi)確(que)保西(xi)門(men)(men)子(zi)(zi)維(wei)修成(cheng)功率，公司(si)以(yi)合理(li)的(de)價(jia)格、良好的(de)信譽，已得到(dao)同行及(ji)西(xi)門(men)(men)子(zi)(zi)用(yong)(yong)戶的(de)認可(ke)(ke)
又(you)叫轉(zhuan)矩(ju)(ju)補(bu)償(chang)，是(shi)為補(bu)償(chang)因(yin)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機定子繞組(zu)電(dian)(dian)(dian)阻所引起(qi)的(de)(de)(de)低(di)速時轉(zhuan)矩(ju)(ju)降低(di)，而把低(di)頻率(lv)范圍 f/V 增大的(de)(de)(de)方法。設(she)定為自動(dong)(dong)(dong)(dong)時，可(ke)使加(jia)速時的(de)(de)(de)電(dian)(dian)(dian)壓自動(dong)(dong)(dong)(dong)提升以補(bu)償(chang)起(qi)動(dong)(dong)(dong)(dong)轉(zhuan)矩(ju)(ju)，使電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機加(jia)速順利進行。如采(cai)用(yong)手動(dong)(dong)(dong)(dong)補(bu)償(chang)時，根據負載特(te)性，尤其是(shi)負載的(de)(de)(de)起(qi)動(dong)(dong)(dong)(dong)特(te)性，通過試驗可(ke)選出(chu)較(jiao)佳曲線。對于變轉(zhuan)矩(ju)(ju)負載，如選擇不(bu)當(dang)會出(chu)現(xian)低(di)速時的(de)(de)(de)輸出(chu)電(dian)(dian)(dian)壓過高(gao)，而浪(lang)費電(dian)(dian)(dian)能的(de)(de)(de)現(xian)象，甚至還會出(chu)現(xian)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)機帶負載起(qi)動(dong)(dong)(dong)(dong)時電(dian)(dian)(dian)流大，而轉(zhuan)速上(shang)不(bu)去的(de)(de)(de)現(xian)象。
