行星(xing)減速機(ji)(ji)(ji)(ji)的主要結構由驅(qu)動(dong)電(dian)機(ji)(ji)(ji)(ji)、行星(xing)齒輪箱組裝而成(cheng)；行星(xing)減速機(ji)(ji)(ji)(ji)可(ke)以配什么電(dian)機(ji)(ji)(ji)(ji)？常(chang)用的驅(qu)動(dong)電(dian)機(ji)(ji)(ji)(ji)有(you)直(zhi)流有(you)刷電(dian)機(ji)(ji)(ji)(ji)、直(zhi)流無刷電(dian)機(ji)(ji)(ji)(ji)、步進(jin)電(dian)機(ji)(ji)(ji)(ji)、空心杯電(dian)機(ji)(ji)(ji)(ji)以及電(dian)機(ji)(ji)(ji)(ji)作為驅(qu)動(dong)電(dian)機(ji)(ji)(ji)(ji)。

直流有刷電機：直流有(you)刷(shua)(shua)電(dian)(dian)(dian)機(ji)(ji)是(shi)一種直流電(dian)(dian)(dian)機(ji)(ji)，有(you)刷(shua)(shua)電(dian)(dian)(dian)機(ji)(ji)的定子上(shang)安(an)裝有(you)固定的主磁極和(he)電(dian)(dian)(dian)刷(shua)(shua)，轉(zhuan)子上(shang)安(an)裝有(you)電(dian)(dian)(dian)樞(shu)繞(rao)組(zu)和(he)換(huan)(huan)向(xiang)(xiang)器。直流電(dian)(dian)(dian)源的電(dian)(dian)(dian)能通(tong)過電(dian)(dian)(dian)刷(shua)(shua)和(he)換(huan)(huan)向(xiang)(xiang)器進入電(dian)(dian)(dian)樞(shu)繞(rao)組(zu)，產生(sheng)電(dian)(dian)(dian)樞(shu)電(dian)(dian)(dian)流，電(dian)(dian)(dian)樞(shu)電(dian)(dian)(dian)流產生(sheng)的磁場與主磁場相(xiang)互作用(yong)產生(sheng)電(dian)(dian)(dian)磁轉(zhuan)矩，使電(dian)(dian)(dian)機(ji)(ji)旋轉(zhuan)帶動(dong)負載(zai)。由于(yu)電(dian)(dian)(dian)刷(shua)(shua)和(he)換(huan)(huan)向(xiang)(xiang)器的存在(zai)，直流有(you)刷(shua)(shua)電(dian)(dian)(dian)機(ji)(ji)的結構復雜，可(ke)(ke)靠性差，故障多，維護(hu)工(gong)作量大，壽命短(duan)，換(huan)(huan)向(xiang)(xiang)火花易(yi)產生(sheng)電(dian)(dian)(dian)磁干擾。直流有(you)刷(shua)(shua)電(dian)(dian)(dian)機(ji)(ji)可(ke)(ke)以配合搭載(zai)行星(xing)齒輪箱一起使用(yong)，這(zhe)種產品稱為行星(xing)直流有(you)刷(shua)(shua)減速電(dian)(dian)(dian)機(ji)(ji)。

直(zhi)(zhi)(zhi)流無(wu)(wu)(wu)刷(shua)電機(ji)(ji)(ji)：無(wu)(wu)(wu)刷(shua)直(zhi)(zhi)(zhi)流電機(ji)(ji)(ji)由(you)電動機(ji)(ji)(ji)主體和驅動器組(zu)成，是一種典(dian)型的(de)(de)(de)(de)機(ji)(ji)(ji)電一體化產(chan)品。 無(wu)(wu)(wu)刷(shua)電機(ji)(ji)(ji)是指無(wu)(wu)(wu)電刷(shua)和換(huan)向器（或集(ji)電環）的(de)(de)(de)(de)電機(ji)(ji)(ji)，又稱(cheng)無(wu)(wu)(wu)換(huan)向器電機(ji)(ji)(ji)。直(zhi)(zhi)(zhi)流電機(ji)(ji)(ji)具有響應快速(su)(su)、較大的(de)(de)(de)(de)起動轉(zhuan)矩、從零轉(zhuan)速(su)(su)至(zhi)額(e)(e)定(ding)轉(zhuan)速(su)(su)具備可提(ti)供額(e)(e)定(ding)轉(zhuan)矩的(de)(de)(de)(de)性能(neng)，但直(zhi)(zhi)(zhi)流電機(ji)(ji)(ji)的(de)(de)(de)(de)優點(dian)也(ye)正是它(ta)的(de)(de)(de)(de)缺點(dian)，因為直(zhi)(zhi)(zhi)流電機(ji)(ji)(ji)要產(chan)生額(e)(e)定(ding)負載下恒定(ding)轉(zhuan)矩的(de)(de)(de)(de)性能(neng)，則電樞(shu)磁(ci)場與轉(zhuan)子磁(ci)場須(xu)恒維持90°，這(zhe)就要藉由(you)碳刷(shua)及整流子。直(zhi)(zhi)(zhi)流無(wu)(wu)(wu)刷(shua)電機(ji)(ji)(ji)可以搭載行星齒輪箱一起使用，這(zhe)種組(zu)裝產(chan)品稱(cheng)為直(zhi)(zhi)(zhi)流無(wu)(wu)(wu)刷(shua)行星減速(su)(su)電機(ji)(ji)(ji)。
