一個(gè)伺服系統(tǒng)，不單單是一個(gè)電機(jī)。它是一個(gè)閉環(huán)的運(yùn)動(dòng)系統(tǒng)控制工程網(wǎng)版權(quán)所有，包含了控制器、驅(qū)動(dòng)器、電儀和反饋裝置，通常一個(gè)還配有一個(gè)光學(xué)或磁編碼器。
伺服系統(tǒng)能在采用永磁（permanent magnets ，PM)技術(shù)后同步機(jī)械，配以有刷或無刷PM電機(jī)，或在一個(gè)AC感應(yīng)電機(jī)上建立異步機(jī)械系統(tǒng)。
永磁同步電機(jī) 有較高的峰值，以及持續(xù)的扭矩，適用于位移系統(tǒng)的高加速度和快速減速中的驅(qū)動(dòng)伺服系統(tǒng)。扭矩與輸入電流直接呈比例關(guān)系。電機(jī)軸速與輸入的電壓相關(guān)。輸入電壓越高，電機(jī)的速度就越高。扭矩和速度的比的曲線呈線性的。

INA軸承的滾道聲及其控制方法滾道聲是當(dāng)軸承運(yùn)轉(zhuǎn)時(shí)，其滾動(dòng)體在滾道面上滾動(dòng)而發(fā)出的一種滑溜連續(xù)的聲音，是所有滾動(dòng)軸承都會(huì)發(fā)生的特有的基本聲。一般的軸承聲即是滾道聲加上其他聲音。球軸承的滾道聲是不規(guī)則的，頻率在1Hz以上，它的主頻率不隨轉(zhuǎn)速而變化，但其總聲壓級(jí)隨轉(zhuǎn)速的加快而增加。滾道聲大的INA軸承，其滾道聲的聲壓級(jí)隨粘度的增加而減少；而滾道聲小的軸承，其聲壓級(jí)在粘度增大至約2mm2/s以上時(shí)，由減少而轉(zhuǎn)為有所增大。
