無刷直流力矩電機的控制，電壓調節通常用于控制直流無刷力矩電機，總結了一下幾種方法。

　　1、控制(zhi)(zhi)(zhi)無刷(shua)直(zhi)流(liu)力矩(ju)(ju)電(dian)(dian)(dian)(dian)機最常用的(de)(de)(de)方法是通(tong)(tong)過脈寬(kuan)調(diao)制(zhi)(zhi)(zhi)直(zhi)接控制(zhi)(zhi)(zhi)電(dian)(dian)(dian)(dian)橋開關(guan)(guan)管(guan)。脈寬(kuan)調(diao)制(zhi)(zhi)(zhi)（PWM）控制(zhi)(zhi)(zhi)通(tong)(tong)常用于調(diao)速(su)。它通(tong)(tong)過電(dian)(dian)(dian)(dian)源開關(guan)(guan)占空(kong)(kong)比(bi)的(de)(de)(de)變化(hua)(hua)來控制(zhi)(zhi)(zhi)電(dian)(dian)(dian)(dian)機的(de)(de)(de)速(su)度(du)，其變化(hua)(hua)相(xiang)當(dang)于外加電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)變化(hua)(hua)。還可用于繞組電(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)控制(zhi)(zhi)(zhi)，實現軟起動、限流(liu)、特定電(dian)(dian)(dian)(dian)流(liu)波(bo)形的(de)(de)(de)控制(zhi)(zhi)(zhi)。由(you)于無刷(shua)直(zhi)流(liu)力矩(ju)(ju)電(dian)(dian)(dian)(dian)機通(tong)(tong)常電(dian)(dian)(dian)(dian)感較大，在(zai)適當(dang)的(de)(de)(de)調(diao)制(zhi)(zhi)(zhi)頻(pin)率下，電(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)流(liu)接近連續且波(bo)動小。調(diao)制(zhi)(zhi)(zhi)頻(pin)率通(tong)(tong)常在(zai)1到(dao)30khz之間。無刷(shua)直(zhi)流(liu)力矩(ju)(ju)電(dian)(dian)(dian)(dian)機采用脈寬(kuan)調(diao)制(zhi)(zhi)(zhi)（PWM）技術。串(chuan)(chuan)聯的(de)(de)(de)功率晶體(ti)管(guan)工作在(zai)開關(guan)(guan)狀態。改(gai)變PWM控制(zhi)(zhi)(zhi)占空(kong)(kong)比(bi)相(xiang)當(dang)于改(gai)變平均調(diao)壓(ya)電(dian)(dian)(dian)(dian)機。可以在(zai)串(chuan)(chuan)行功率晶體(ti)管(guan)的(de)(de)(de)末(mo)端添加一個濾波(bo)器(qi)，以減少控制(zhi)(zhi)(zhi)器(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)壓(ya)波(bo)動。

　　2、如果無刷直(zhi)流(liu)力矩(ju)電機接入的系(xi)統是一個(ge)需(xu)要(yao)整流(liu)電路獲取直(zhi)流(liu)母(mu)線電壓的交流(liu)電源，則(ze)采用晶閘管(guan)構成可控(kong)整流(liu)橋，通過調(diao)相方式調(diao)節直(zhi)流(liu)母(mu)線電壓的大小。該控(kong)制方法適用于動態性能要(yao)求較低的場合。

　　如果它已經是一個(ge)直流(liu)電(dian)(dian)源，最簡單的例子是將(jiang)一個(ge)功(gong)(gong)率晶體(ti)管串(chuan)聯到(dao)連(lian)接到(dao)控(kong)制器(qi)的直流(liu)母線上，以(yi)調整(zheng)控(kong)制器(qi)的直流(liu)電(dian)(dian)壓。功(gong)(gong)率晶體(ti)管可以(yi)在放(fang)大器(qi)狀態(tai)下工作，控(kong)制器(qi)的電(dian)(dian)壓可以(yi)連(lian)續變化。這種控(kong)制方式(shi)電(dian)(dian)路(lu)相對簡單帶(dai)寬大。但由于(yu)功(gong)(gong)率晶體(ti)管損耗大，整(zheng)體(ti)效(xiao)率低，僅適用于(yu)低功(gong)(gong)率系統。
