微型減速馬達是體積、容量較小，輸出功率一般在數百瓦以下的電機和用途、性能及環境條件要求的電機，全稱微型減速電機，簡稱微電機。微型電機因其質量好和微小的特點，應用于各個領域。它的引線的更換使得電動機換向。

微型減速(su)馬達只有兩根引線(xian)，調節供電(dian)電(dian)壓或電(dian)流可調速(su)，更(geng)換(huan)兩根引線(xian)的(de)(de)性，電(dian)動機(ji)換(huan)向，其(qi)傳動電(dian)路受單片機(ji)控制(zhi)，一般要求能進(jin)行(xing)正反轉和調速(su)傳動，而且體積不宜太大。可按實際需要選擇任意轉速(su)和各(ge)種結(jie)構(gou)(gou)形式，產(chan)品采(cai)用(yong)了系列化、模(mo)塊化的(de)(de)設計思想,有的(de)(de)適應性,微型電(dian)機(ji)有其(qi)多的(de)(de)電(dian)機(ji)組(zu)合、安裝位置和結(jie)構(gou)(gou)方案。
