style="text-indent:25px">由于電機運轉(zhuǎn)時會產(chǎn)生反電動勢而反電動勢的大小通常與轉(zhuǎn)速成正比。因此當(dāng)電機運轉(zhuǎn)到一定速度時，由于反電動勢大小與外加電壓大小相同，此時的速度稱為基速。恒轉(zhuǎn)矩控制：電機在基速下，進行恒轉(zhuǎn)矩控制。此時電機的反電動勢E與電機的轉(zhuǎn)速成正比。又電機的輸出功率與電機的轉(zhuǎn)矩及轉(zhuǎn)速乘積成正比，因此此時電機功率與轉(zhuǎn)速成正比。恒功率控制：當(dāng)電機超過基速后，通過調(diào)節(jié)電機勵磁電流來使電機的反電動勢基本保持恒定，以此提高電機的轉(zhuǎn)速。此時，電機的輸出功率基本保持恒定，但電機轉(zhuǎn)矩與轉(zhuǎn)速成反比例下降。弱磁控制：當(dāng)電機轉(zhuǎn)速超過一定數(shù)值后，勵磁電流已經(jīng)相當(dāng)小，基本不能再調(diào)節(jié)，此時進入弱磁控制階段。盤式制動器生產(chǎn)廠家同步電動機的轉(zhuǎn)子轉(zhuǎn)速與負載大小無關(guān)而始終保持為同步轉(zhuǎn)速。</p><div

style="text-indent:25px">電機是指依據(jù)電磁感應(yīng)定律實現(xiàn)電能轉(zhuǎn)換或傳遞的一種電磁裝置。電機在電路中是用字母M表示，它的主要作用是產(chǎn)生驅(qū)動轉(zhuǎn)矩，作為用電器或各種機械的動力源，發(fā)電機在電路中用字母G表示，它的主要作用是利用機械能轉(zhuǎn)化為電能。按工作電源種類劃分：可分為直流電機和交流電機。直流電動機按結(jié)構(gòu)及工作原理可劃分：無刷直流電動機和有刷直流電動機。有刷直流電動機可劃分：永磁直流電動機和電磁直流電動機。電磁直流電動機劃分：串勵直流電動機、并勵直流電動機、他勵直流電動機和復(fù)勵直流電動機。永磁直流電動機劃分：稀土永磁直流電動機、鐵氧體永磁直流電動機和鋁鎳鈷永磁直流電動機。其中交流電機還可劃分：單相電機和三相電機。按結(jié)構(gòu)和工作原理可劃分：可分為直流電動機、異步電動機、同步電動機。同步電機可劃分：永磁同步電動機、磁阻同步電動機和磁滯同步電動機。異步電機可劃分：感應(yīng)電動機和交流換向器電動機。感應(yīng)電動機可劃分：三相異步電動機、單相異步電動機和罩極異步電動機等。交流換向器電動機可劃分：單相串勵電動機、交直流兩用電動機和推斥電動機。</p><p style="text-indent:25px">電源部可以直接以直流電輸入或以交流電輸入，如果輸入是交流電就得先經(jīng)轉(zhuǎn)換器轉(zhuǎn)成直流。不論是直流電輸入或交流電輸入要轉(zhuǎn)入電機線圈前須先將直流電壓由換流器（Inverter）轉(zhuǎn)成3相電壓來驅(qū)動電機。換流器一般由6個功率晶體管分為上臂/下臂連接電機作為控制流經(jīng)電機線圈的開關(guān)?？刂撇縿t提供（脈沖寬度調(diào)制）決定功率晶體管開關(guān)頻度及換流器換相的時機。直流無刷電機一般希望使用在當(dāng)負載變動時速度可以穩(wěn)定于設(shè)定值而不會變動太大的速度控制，所以電機內(nèi)部裝有能感應(yīng)磁場的霍爾傳感器，作為速度之閉回路控制，同時也做為相序控制的依據(jù)。但這只是用來做為速度控制并不能拿來做為定位控制。直流電機具有響應(yīng)快速、較大的起動轉(zhuǎn)矩、從零轉(zhuǎn)速至額定轉(zhuǎn)速具備可提供額定轉(zhuǎn)矩的性能。</p><div
