style="text-indent:25px">直流電機(jī)的勵磁方式是指對勵磁繞組如何供電、產(chǎn)生勵磁磁通勢而建立主磁場的問題。根據(jù)勵磁方式的不同，直流電機(jī)可分為下列幾種類型。勵磁繞組與電樞繞組無聯(lián)接關(guān)系，而由其他直流電源對勵磁繞組供電的直流電機(jī)稱為他勵直流電機(jī)，M表示電動機(jī)，若為發(fā)電機(jī)，則用G表示。永磁直流電機(jī)也可看作他勵直流電機(jī)。并勵直流電機(jī)的勵磁繞組與電樞繞組相并聯(lián)。作為并勵發(fā)電機(jī)來說，是電機(jī)本身發(fā)出來的端電壓為勵磁繞組供電；作為并勵電動機(jī)來說，勵磁繞組與電樞共用同一電源，從性能上講與他勵直流電動機(jī)相同。串勵直流電機(jī)的勵磁繞組與電樞繞組串聯(lián)后，再接于直流電源。這種直流電機(jī)的勵磁電流就是電樞電流。渦流制動器費(fèi)用異步電動機(jī)的轉(zhuǎn)子轉(zhuǎn)速總是略低于旋轉(zhuǎn)磁場的同步轉(zhuǎn)速。</p><div
