1、直流伺服電動機(jī)的基本結(jié)構(gòu)
圖為直流伺服電動機(jī)的結(jié)構(gòu)，主要包括定子、轉(zhuǎn)子、電刷與換向片三個部分
2. 直流伺服電動機(jī)的分類
?。?）根據(jù)電動機(jī)本身結(jié)構(gòu)的不同，可分為以下幾類：
改進(jìn)型直流伺服電動機(jī)轉(zhuǎn)子的轉(zhuǎn)動慣量較小，過載能力較強(qiáng)，且具有較好的換向性能。
小慣量直流電動機(jī)zui大限度地減少了轉(zhuǎn)子的轉(zhuǎn)動慣量，能獲得的快速特性。
永磁直流伺服電動機(jī)能在較大過載轉(zhuǎn)矩下*地工作，轉(zhuǎn)動慣量較大，無勵磁回路損耗，可在低速下運(yùn)轉(zhuǎn)。
無刷直流電動機(jī)由同步電動機(jī)和逆變器組成，而逆變器是由裝在轉(zhuǎn)子上的轉(zhuǎn)子位置傳感器控制。
?。?）根據(jù)直流電動機(jī)對勵磁繞組的勵磁方式不同，可分為他勵式、并勵式、串勵式和復(fù)勵式四種。
