微型減速馬達是(shi)體積、容(rong)量較小，輸出(chu)功率一(yi)般在數百(bai)瓦以下的電(dian)(dian)機(ji)和(he)用(yong)途、性能及環境條件要求的電(dian)(dian)機(ji)，全(quan)稱(cheng)微(wei)型減速電(dian)(dian)機(ji)，簡稱(cheng)微(wei)電(dian)(dian)機(ji)。微(wei)型電(dian)(dian)機(ji)因其(qi)質量好和(he)微(wei)小的特(te)點，應用(yong)于各個領域。它的引線的更換使得電(dian)(dian)動機(ji)換向。

微型(xing)減速(su)(su)馬(ma)達只有兩根引(yin)(yin)線(xian)，調節供(gong)電(dian)(dian)電(dian)(dian)壓或電(dian)(dian)流可(ke)調速(su)(su)，更換兩根引(yin)(yin)線(xian)的(de)性，電(dian)(dian)動(dong)機(ji)換向(xiang)，其驅動(dong)電(dian)(dian)路受單片機(ji)控(kong)制，一般(ban)要(yao)求(qiu)能進行(xing)正反轉和調速(su)(su)驅動(dong)，而且(qie)體積(ji)不宜太大。可(ke)按實際需要(yao)選擇(ze)任意轉速(su)(su)和各(ge)種結(jie)構(gou)形式，產品采用(yong)了系列化、模塊化的(de)設計思想(xiang),有的(de)適應性,微型(xing)電(dian)(dian)機(ji)有其多的(de)電(dian)(dian)機(ji)組(zu)合、安裝位置和結(jie)構(gou)方案。

引線的(de)性(xing)(xing)是微型直流電(dian)(dian)動(dong)(dong)機(ji)(ji)驅動(dong)(dong)電(dian)(dian)路(lu)(lu)的(de)關(guan)鍵(jian)，一(yi)般說來，用(yong)(yong)于驅動(dong)(dong)機(ji)(ji)械的(de)側重于運行及起動(dong)(dong)時(shi)的(de)力能指標，作電(dian)(dian)源用(yong)(yong)的(de)要(yao)考慮輸出功(gong)率、波形和穩定性(xing)(xing)，控制用(yong)(yong)微型電(dian)(dian)機(ji)(ji)則偏重于靜態和動(dong)(dong)態的(de)特性(xing)(xing)參(can)數，前兩(liang)類(lei)電(dian)(dian)機(ji)(ji)的(de)特性(xing)(xing)參(can)數與普通電(dian)(dian)機(ji)(ji)相似。微型電(dian)(dian)機(ji)(ji)采用(yong)(yong)添加合(he)適上拉電(dian)(dian)阻來提(ti)微型電(dian)(dian)機(ji)(ji)驅動(dong)(dong)電(dian)(dian)路(lu)(lu)的(de)靈敏度(du)，從(cong)而充分發揮軟件的(de)作用(yong)(yong)，通過加大輸出電(dian)(dian)壓范圍以增加負(fu)載(zai)能力，各種電(dian)(dian)路(lu)(lu)各有利蔽，要(yao)根據實際情況而選(xuan)用(yong)(yong)。
