電動(dong)機是(shi)感性(xing)負載還(huan)是(shi)容性(xing)負載?

電(dian)(dian)動(dong)(dong)機屬(shu)于感(gan)性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)。負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)分為(wei)感(gan)性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)、容性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)、阻(zu)性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)。感(gan)性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)：即和電(dian)(dian)源相比當負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)電(dian)(dian)流滯后負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)電(dian)(dian)壓一(yi)個相位(wei)(wei)差時負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)為(wei)感(gan)性(xing)(如(ru)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)為(wei)電(dian)(dian)動(dong)(dong)機、變(bian)壓器)。容性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)：即和電(dian)(dian)源相比當負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)電(dian)(dian)流超前負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)電(dian)(dian)壓一(yi)個相位(wei)(wei)差時負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)為(wei)容性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)。電(dian)(dian)動(dong)(dong)機，其通(tong)過三相交流電(dian)(dian)源在三相線圈繞組，由電(dian)(dian)磁感(gan)應產生旋轉(zhuan)磁場。使電(dian)(dian)動(dong)(dong)機運轉(zhuan)。這些電(dian)(dian)動(dong)(dong)機線圈繞組都是(shi)電(dian)(dian)感(gan)器。所以，是(shi)感(gan)性(xing)負(fu)(fu)(fu)載(zai)(zai)(zai)(zai)(zai)。

電動機的工作原理

它是利用(yong)通電(dian)(dian)(dian)線圈(也就是定(ding)子繞組(zu))產生旋(xuan)轉(zhuan)(zhuan)磁場(chang)并作(zuo)用(yong)于轉(zhuan)(zhuan)子(如(ru)鼠籠式閉(bi)合鋁框)形成磁電(dian)(dian)(dian)動(dong)(dong)力旋(xuan)轉(zhuan)(zhuan)扭矩。電(dian)(dian)(dian)動(dong)(dong)機(ji)按使用(yong)電(dian)(dian)(dian)源(yuan)不(bu)同(tong)(tong)分(fen)為(wei)直流(liu)電(dian)(dian)(dian)動(dong)(dong)機(ji)和交流(liu)電(dian)(dian)(dian)動(dong)(dong)機(ji)，電(dian)(dian)(dian)力系統中的電(dian)(dian)(dian)動(dong)(dong)機(ji)大部分(fen)是交流(liu)電(dian)(dian)(dian)動(dong)(dong)機(ji),可以是同(tong)(tong)步電(dian)(dian)(dian)動(dong)(dong)機(ji)或(huo)者是異(yi)步電(dian)(dian)(dian)動(dong)(dong)機(ji)(電(dian)(dian)(dian)動(dong)(dong)機(ji)定(ding)子磁場(chang)轉(zhuan)(zhuan)速與轉(zhuan)(zhuan)子旋(xuan)轉(zhuan)(zhuan)轉(zhuan)(zhuan)速不(bu)保持同(tong)(tong)步速)。

電(dian)動(dong)(dong)機(ji)主要由(you)定子(zi)與轉子(zi)組(zu)成,通電(dian)導(dao)線(xian)在磁(ci)場(chang)中受力運動(dong)(dong)的方向(xiang)跟電(dian)流方向(xiang)和磁(ci)感線(xian)(磁(ci)場(chang)方向(xiang))方向(xiang)有關。電(dian)動(dong)(dong)機(ji)工作原理是磁(ci)場(chang)對電(dian)流受力的作用,使電(dian)動(dong)(dong)機(ji)轉動(dong)(dong)。
