阿克蘇直流發(fā)電機(jī)的工作原理

直流發(fā)電機(jī)地工作原理就是把電樞線圈中感應(yīng)地交變電動(dòng)勢(shì)，靠換向器配合電刷地?fù)Q向作用，使之從電刷端引出時(shí)變?yōu)橹绷麟妱?dòng)勢(shì)地原理。

感應(yīng)電動(dòng)勢(shì)地方向按右手定則確定（磁感線指向手心，大拇指指向?qū)w運(yùn)動(dòng)方向，其他四指地指向就是導(dǎo)體中感應(yīng)電動(dòng)勢(shì)地方向）。

工作原理

導(dǎo)體受力地方向用左手定則確定。這一對(duì)電磁力形成了作用于電樞一個(gè)力矩，這個(gè)力矩在旋轉(zhuǎn)電機(jī)里稱為電磁轉(zhuǎn)矩，轉(zhuǎn)矩地方向是逆時(shí)針?lè)较?，企圖使電樞逆時(shí)針?lè)较蜣D(zhuǎn)動(dòng)。如果此電磁轉(zhuǎn)矩能夠克服電樞上地阻轉(zhuǎn)矩（例如由摩擦引起地阻轉(zhuǎn)矩以及其它負(fù)載轉(zhuǎn)矩），電樞就能按逆時(shí)針?lè)较蛐D(zhuǎn)起來(lái)。

直流電動(dòng)機(jī)是依靠直流工作電壓運(yùn)行地電動(dòng)機(jī)，廣泛應(yīng)用于收錄機(jī)、錄像機(jī)、影碟機(jī)、電動(dòng)剃須刀、電吹風(fēng)、電子表、玩具等。
