描述
逆時針和順時針，是要從什么方向來看，這只是看的方向的問題，從這個方向是順時針從另外一個方向就是逆時針，沒有人規(guī)定電機總是順時針轉(zhuǎn)的，以三相異步電機為例，任何兩條相線接法顛倒了，電機會立馬反向，也就是原來所謂的順時針，會變成逆時針旋轉(zhuǎn)了。
對電機旋轉(zhuǎn)方向的術(shù)語是有國標(biāo)規(guī)定的，只稱為順時針還是逆時針，但是沒有誰規(guī)定電機一定要順時針轉(zhuǎn)。如果只有一個軸伸，或不同直徑的兩個軸伸，從軸伸端看（對兩個軸伸的看大直徑端）；如果有兩個相同直徑軸伸的，或者沒有軸伸，則從有換向器或滑環(huán)端看；如果一端有換向器而另一端有滑環(huán)，則從滑環(huán)端看。電動機的轉(zhuǎn)向是順時針的稱順時針旋轉(zhuǎn)，逆時針的稱逆時針旋轉(zhuǎn)。
發(fā)動機大都是順時針旋轉(zhuǎn)的，別把發(fā)動機和電機混淆了，發(fā)動機順時針轉(zhuǎn)的主要原因如下：按照傳動系統(tǒng)的設(shè)計，面對風(fēng)扇當(dāng)發(fā)動機順時針運轉(zhuǎn)時，扭矩經(jīng)過變速箱，傳動軸，驅(qū)動橋，最終到達(dá)車輪上剛好是使前進(jìn)的方向。在發(fā)動機剛開始問世的時候，起動根本不是靠起動機，一般都是靠人力起動。一般人都習(xí)慣用右手，所以在設(shè)計發(fā)動機的時候，考慮到人站在發(fā)動機前面，使用右手方便，所以就設(shè)計成順時針方向了。大多數(shù)發(fā)動機都是如此，也有少數(shù)賽車或者航空發(fā)動機是逆時針運轉(zhuǎn)的，具體要看需要了。電機節(jié)能智能電機節(jié)電設(shè)備。
