說起力矩(ju)電(dian)機(ji)，注意(yi)電(dian)壓調(diao)節裝置的電(dian)流(liu)，在(zai)使用轉矩(ju)電(dian)機(ji)時，轉速(su)的范圍(wei)也是很(hen)重要的。因為(wei)結構和連接方式的不同(tong)，力矩(ju)電(dian)機(ji)一般分(fen)為(wei)四種(zhong)類型。

　　力矩電(dian)(dian)(dian)(dian)動(dong)機(ji)的(de)(de)(de)控制(zhi)是(shi)根(gen)據不同(tong)的(de)(de)(de)要(yao)求調整其(qi)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)，以適應不同(tong)的(de)(de)(de)負載要(yao)求，可采用(yong)任何(he)一種調壓(ya)(ya)裝(zhuang)(zhuang)置(zhi)。電(dian)(dian)(dian)(dian)壓(ya)(ya)調節裝(zhuang)(zhuang)置(zhi)的(de)(de)(de)功率應根(gen)據電(dian)(dian)(dian)(dian)機(ji)銘牌校準(zhun)的(de)(de)(de)電(dian)(dian)(dian)(dian)流確定。在使用(yong)轉(zhuan)矩電(dian)(dian)(dian)(dian)動(dong)機(ji)時(shi)，其(qi)轉(zhuan)速范圍的(de)(de)(de)選(xuan)(xuan)擇是(shi)非常重要(yao)的(de)(de)(de)。當(dang)電(dian)(dian)(dian)(dian)機(ji)用(yong)于(yu)繞線時(shi)的(de)(de)(de)特性，選(xuan)(xuan)擇的(de)(de)(de)輸(shu)出(chu)轉(zhuan)矩接近(jin)所(suo)要(yao)求的(de)(de)(de)轉(zhuan)矩，避免選(xuan)(xuan)擇太大，太大的(de)(de)(de)輸(shu)出(chu)轉(zhuan)矩，在小(xiao)負荷設備中使用(yong)，會使電(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)輸(shu)入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)降很低。當(dang)電(dian)(dian)(dian)(dian)壓(ya)(ya)過低時(shi)，電(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)轉(zhuan)矩-轉(zhuan)速曲線相對平坦。一般輸(shu)入(ru)電(dian)(dian)(dian)(dian)壓(ya)(ya)不應小(xiao)于(yu)200V.

　　由于(yu)結(jie)構(gou)和連(lian)接方式的(de)不同，力矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)控制(zhi)器(qi)(qi)(qi)可分(fen)為四種類型：電(dian)(dian)(dian)(dian)(dian)源線(xian)輸入連(lian)接到(dao)扭矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)控制(zhi)器(qi)(qi)(qi)，然后輸出(chu)扭矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)控制(zhi)器(qi)(qi)(qi)，再連(lian)接到(dao)電(dian)(dian)(dian)(dian)(dian)機(ji)（作為電(dian)(dian)(dian)(dian)(dian)機(ji)輸入電(dian)(dian)(dian)(dian)(dian)源）端。力矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)控制(zhi)器(qi)(qi)(qi)只有三個端子。力矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)星點(dian)與電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)三個點(dian)分(fen)別連(lian)接。當電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)新型出(chu)現時(shi)，調節線(xian)圈電(dian)(dian)(dian)(dian)(dian)壓(ya)。設計(ji)了具有模擬接口的(de)轉(zhuan)矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)控制(zhi)器(qi)(qi)(qi)，用于(yu)變頻(pin)器(qi)(qi)(qi)的(de)信號(hao)采集(ji)。讓它(ta)完(wan)全閉環控制(zhi)。雙(shuang)電(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)轉(zhuan)矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)控制(zhi)器(qi)(qi)(qi)，兩個電(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)控制(zhi)電(dian)(dian)(dian)(dian)(dian)壓(ya)不同，轉(zhuan)矩(ju)(ju)(ju)電(dian)(dian)(dian)(dian)(dian)機(ji)在電(dian)(dian)(dian)(dian)(dian)壓(ya)較高或(huo)較低時(shi)，電(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)(qi)(qi)自動轉(zhuan)換更準確。
