行星減速馬達也稱為行星減速機，行星齒輪箱，行星減速器；主要架構由行星減速器和馬達組成，在的減速機廠家則是自己研發行星減速器，采購馬達，集成組裝而成；可以根據客戶的要求來定制組裝行星減速馬達。

  行(xing)(xing)星(xing)減速馬達的工(gong)作原理(li)，由(you)一(yi)(yi)個內(nei)(nei)齒(chi)(chi)(chi)(chi)環緊密結(jie)合於(wu)(wu)(wu)齒(chi)(chi)(chi)(chi)箱(xiang)殼體(ti)上，環齒(chi)(chi)(chi)(chi)中心有(you)一(yi)(yi)個自(zi)外部動(dong)力(li)所傳動(dong)之(zhi)(zhi)太(tai)陽(yang)齒(chi)(chi)(chi)(chi)輪(lun)(lun)，介於(wu)(wu)(wu)兩者(zhe)之(zhi)(zhi)間有(you)一(yi)(yi)組由(you)三顆齒(chi)(chi)(chi)(chi)輪(lun)(lun)等分組合於(wu)(wu)(wu)托(tuo)盤上之(zhi)(zhi)行(xing)(xing)星(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)組該組行(xing)(xing)星(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)依靠(kao)著出(chu)力(li)軸、內(nei)(nei)齒(chi)(chi)(chi)(chi)環及太(tai)陽(yang)齒(chi)(chi)(chi)(chi)支撐(cheng)浮游於(wu)(wu)(wu)期(qi)間；行(xing)(xing)星(xing)減速機當入力(li)側動(dong)力(li)傳動(dong)太(tai)陽(yang)齒(chi)(chi)(chi)(chi)時(shi)，可帶(dai)動(dong)行(xing)(xing)星(xing)齒(chi)(chi)(chi)(chi)輪(lun)(lun)自(zi)轉，并依循著內(nei)(nei)齒(chi)(chi)(chi)(chi)環之(zhi)(zhi)軌(gui)跡沿著中心公轉，游星(xing)之(zhi)(zhi)旋(xuan)轉帶(dai)動(dong)連結(jie)於(wu)(wu)(wu)托(tuo)盤之(zhi)(zhi)出(chu)力(li)軸輸出(chu)動(dong)力(li)。
