目前，電機運轉(zhuǎn)調(diào)速控制在當(dāng)代的應(yīng)用可謂是越來越廣泛，電機運轉(zhuǎn)調(diào)速控制是值得我們好好學(xué)習(xí)的，現(xiàn)在我們就深入了解電機運轉(zhuǎn)調(diào)速控制。 電機控制是指，對電機的啟動、加速、運轉(zhuǎn)、減速及停止進(jìn)行的控制。根據(jù)不同電機的類型及電機的使用場合有不同的要求及目的。對于電動機，通過電機控制，達(dá)到電機快速啟動、快速響應(yīng)、率、高轉(zhuǎn)矩輸出及高過載能力的目的。
電機調(diào)速方法包括：串電阻調(diào)速、變頻調(diào)速、變極調(diào)速及矢量控制、直接轉(zhuǎn)矩控制等。
串電阻調(diào)速主要用于異步電機。調(diào)速范圍受到電機轉(zhuǎn)矩限制。
變頻調(diào)速適用于感應(yīng)電機。通過調(diào)節(jié)同步速達(dá)到調(diào)速的目的。
變極調(diào)速通過改變電機極數(shù)，產(chǎn)生1/2、1/3...的轉(zhuǎn)速。
矢量控制技術(shù)是由德國學(xué)者Blaschke在1971年提出的。通過對電機的勵磁繞組和電樞繞組解耦，使控制感應(yīng)電機與控制直流電機一樣。通過分別調(diào)節(jié)電機勵磁與電樞電流的大小，來控制電機的轉(zhuǎn)矩、轉(zhuǎn)速、反電動勢等。
直接轉(zhuǎn)矩控制由德國學(xué)者Depenbrock于1985年提出。它直接控制定子磁鏈空間矢量和電磁轉(zhuǎn)矩，具有快速響應(yīng)的能力。

伺服電動機
一般分為直流伺服和交流伺服.
對于直流伺服馬達(dá)
優(yōu)點:的速度控制,轉(zhuǎn)矩速度特性很硬,原理簡單、使用方便,價格優(yōu)勢
缺點:電刷換向,速度限制,附加阻力,產(chǎn)生磨損微粒(對于無塵室)
對于交流伺服馬達(dá)
優(yōu)點:良好的速度控制特性，在整個速度區(qū)內(nèi)可實現(xiàn)平滑控制，幾乎無振蕩;率，90%以上，不發(fā)熱;高速控制;高位置控制（取決于何種編碼器）;額定運行區(qū)域內(nèi)，實現(xiàn)恒力矩;低噪音;沒有電刷的磨損，免維護(hù);不產(chǎn)生磨損顆粒、沒有火花，適用于無塵間、易暴環(huán)境
慣量低;

為避免松脫，游動軸承內(nèi)圈應(yīng)與軸作軸向固定（常采用彈性擋圈）。用圓柱滾子軸承作游動支點時，軸承外圈要與機座作軸向固定，靠滾子與套圈間的游動來保證軸的自由伸縮。要求能左右雙向游動的軸，可采用兩端游動的軸系結(jié)構(gòu)。為人字齒輪傳動的高速主動軸，為了自動補償輪齒兩側(cè)螺旋角的誤差，使輪齒受力均勻，采用允許軸系左右少量軸向游動的結(jié)構(gòu)，故兩端都選用圓柱滾子軸承。與其相嚙合的低速齒輪軸系則必須兩端固定，以便兩軸都得到軸向定位。
