力矩(ju)電機具有轉速(su)低(di)、力矩(ju)大、過載能力強(qiang)、響應速(su)度快、線(xian)性(xing)度好、力矩(ju)波動(dong)小的(de)特點(dian)。它可以在不減(jian)少(shao)傳動(dong)齒輪的(de)情況下直接驅動(dong)負載，從而提(ti)高系統的(de)運(yun)行精度。

　　力矩電機調壓器的常見調整形式如下：

　　（1）三(san)相平(ping)衡(heng)(heng)調(diao)整。采(cai)用(yong)三(san)相穩壓(ya)器，星形連(lian)接，同(tong)軸控(kong)制，同(tong)時調(diao)節(jie)三(san)相電(dian)壓(ya)達(da)到平(ping)衡(heng)(heng)，使(shi)力矩電(dian)機(ji)在平(ping)衡(heng)(heng)狀(zhuang)態下(xia)運行(xing)，具有調(diao)節(jie)范圍(wei)廣(guang)、效(xiao)果好(hao)等(deng)優點。如果你(ni)運用(yong)三(san)相穩定器，它(ta)不是很經濟。

　　（2）兩相(xiang)電(dian)(dian)(dian)壓(ya)(ya)(ya)調(diao)節(jie)。兩個單(dan)(dan)相(xiang)穩(wen)壓(ya)(ya)(ya)器(qi)(qi)用作(zuo)u型連(lian)接和同軸調(diao)節(jie)。例如，調(diao)整A相(xiang)和C相(xiang)時，調(diao)節(jie)器(qi)(qi)A和C的滑動刷同時對稱滑動，也(ye)可(ke)(ke)以實現平(ping)衡調(diao)節(jie)。但在(zai)運用這種(zhong)方法時，需要注意的是u型單(dan)(dan)相(xiang)調(diao)壓(ya)(ya)(ya)器(qi)(qi)的端電(dian)(dian)(dian)壓(ya)(ya)(ya)為電(dian)(dian)(dian)源線(xian)電(dian)(dian)(dian)壓(ya)(ya)(ya)，所運用的單(dan)(dan)相(xiang)調(diao)壓(ya)(ya)(ya)器(qi)(qi)的額定電(dian)(dian)(dian)壓(ya)(ya)(ya)應(ying)與(yu)電(dian)(dian)(dian)源線(xian)電(dian)(dian)(dian)壓(ya)(ya)(ya)相(xiang)對應(ying)。生(sheng)產的大(da)多數單(dan)(dan)相(xiang)穩(wen)壓(ya)(ya)(ya)器(qi)(qi)額定電(dian)(dian)(dian)壓(ya)(ya)(ya)為220V,不(bu)可(ke)(ke)用作(zuo)常見380V三(san)相(xiang)電(dian)(dian)(dian)力系統，只能(neng)用作(zuo)220V三(san)相(xiang)電(dian)(dian)(dian)力系統。

   （3）單(dan)相監管。它(ta)只用一個單(dan)相調(diao)壓器(qi)來調(diao)節單(dan)相電壓。
