同步(bu)電動機與異(yi)步(bu)電動機都是咱們(men)比較常見的電動機品種，這兩種不(bu)同的電動機各(ge)有(you)各(ge)的特(te)征(zheng)，接下來小(xiao)編簡單為咱們(men)介紹一下。
1、同步電(dian)動(dong)(dong)機：同步電(dian)動(dong)(dong)機(synchronousmotor)是由直流供電(dian)的(de)(de)勵磁(ci)(ci)磁(ci)(ci)場(chang)(chang)與電(dian)樞的(de)(de)旋轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)磁(ci)(ci)場(chang)(chang)彼此作(zuo)(zuo)用(yong)而發作(zuo)(zuo)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)矩，以同步轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)速(su)旋轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)的(de)(de)溝通電(dian)動(dong)(dong)機，轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)速(su)與定子(zi)旋轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)磁(ci)(ci)場(chang)(chang)的(de)(de)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)速(su)相同的(de)(de)溝通電(dian)機。其(qi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)速(su)n與磁(ci)(ci)極對數p、電(dian)源頻(pin)率(lv)f之(zhi)間滿意(yi)n=60f/p。轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)速(su)n決議(yi)于(yu)電(dian)源頻(pin)率(lv)f，故(gu)電(dian)源頻(pin)率(lv)必(bi)守時(shi)，轉(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)(zhuan)速(su)不變，且與負(fu)載無關。具有工作(zuo)(zuo)安(an)穩性高和(he)過(guo)載才干(gan)大等特征。常用(yong)于(yu)多機同步傳動(dong)(dong)體系、精(jing)細(xi)調(diao)速(su)穩速(su)體系和(he)大型設備(如軋鋼機)等。
同(tong)(tong)(tong)步(bu)電(dian)(dian)(dian)動機(ji)是(shi)(shi)歸于溝(gou)通電(dian)(dian)(dian)機(ji)，定子繞組(zu)與異步(bu)電(dian)(dian)(dian)動機(ji)相同(tong)(tong)(tong)。它的(de)(de)轉子旋轉速度(du)與定子繞組(zu)所發作的(de)(de)旋轉磁場的(de)(de)速度(du)是(shi)(shi)相同(tong)(tong)(tong)的(de)(de)，所以(yi)稱為同(tong)(tong)(tong)步(bu)電(dian)(dian)(dian)動機(ji)。正因為這樣(yang)，同(tong)(tong)(tong)步(bu)電(dian)(dian)(dian)動機(ji)的(de)(de)電(dian)(dian)(dian)流在(zai)相位上是(shi)(shi)超前于電(dian)(dian)(dian)壓(ya)的(de)(de)，即同(tong)(tong)(tong)步(bu)電(dian)(dian)(dian)動機(ji)是(shi)(shi)一個容性負載。為此，在(zai)許多時(shi)分，同(tong)(tong)(tong)步(bu)電(dian)(dian)(dian)動機(ji)是(shi)(shi)用以(yi)改善供電(dian)(dian)(dian)體系的(de)(de)功率因數的(de)(de)。
2、異步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)：異步電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)即轉(zhuan)(zhuan)子(zi)置于旋(xuan)(xuan)轉(zhuan)(zhuan)磁場(chang)中(zhong)(zhong)，在旋(xuan)(xuan)轉(zhuan)(zhuan)磁場(chang)的(de)作用下，獲得一(yi)個滾動(dong)(dong)(dong)(dong)(dong)力矩，因而轉(zhuan)(zhuan)子(zi)滾動(dong)(dong)(dong)(dong)(dong)，轉(zhuan)(zhuan)子(zi)是可滾動(dong)(dong)(dong)(dong)(dong)的(de)導體，一(yi)般多呈鼠籠狀(zhuang)。定子(zi)是電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)中(zhong)(zhong)不(bu)滾動(dong)(dong)(dong)(dong)(dong)的(de)部(bu)分，首要(yao)任務是發作一(yi)個旋(xuan)(xuan)轉(zhuan)(zhuan)磁場(chang)。旋(xuan)(xuan)轉(zhuan)(zhuan)磁場(chang)并不(bu)是用機(ji)械辦法來完結。而是以(yi)溝通(tong)電(dian)通(tong)于數對電(dian)磁鐵中(zhong)(zhong)，使其(qi)磁極性質循(xun)環(huan)改(gai)動(dong)(dong)(dong)(dong)(dong)，故相當(dang)于一(yi)個旋(xuan)(xuan)轉(zhuan)(zhuan)的(de)磁場(chang)。這種(zhong)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)并不(bu)像直流電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)有電(dian)刷(shua)或集電(dian)環(huan)，依據(ju)所用溝通(tong)電(dian)的(de)品種(zhong)有單相電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)和三相電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)，單相電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)用在如洗衣機(ji)，電(dian)風扇等;三相電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)則(ze)作為工廠的(de)動(dong)(dong)(dong)(dong)(dong)力設備。
經(jing)過定子(zi)發(fa)作(zuo)(zuo)的(de)旋轉(zhuan)(zhuan)(zhuan)(zhuan)磁場(其轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)為(wei)同步轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)n1)與轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)繞(rao)組的(de)相對(dui)運動(dong)(dong)(dong)，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)繞(rao)組切割磁感(gan)線發(fa)作(zuo)(zuo)感(gan)應電動(dong)(dong)(dong)勢，然后使(shi)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)繞(rao)組中(zhong)發(fa)作(zuo)(zuo)感(gan)應電流(liu)。轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)繞(rao)組中(zhong)的(de)感(gan)應電流(liu)與磁場作(zuo)(zuo)用(yong)，發(fa)作(zuo)(zuo)電磁轉(zhuan)(zhuan)(zhuan)(zhuan)矩(ju)，使(shi)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)旋轉(zhuan)(zhuan)(zhuan)(zhuan)。因為(wei)當(dang)轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)逐(zhu)漸(jian)接(jie)近同步轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)時，感(gan)應電流(liu)逐(zhu)漸(jian)減小，所發(fa)作(zuo)(zuo)的(de)電磁轉(zhuan)(zhuan)(zhuan)(zhuan)矩(ju)也相應減小，當(dang)異步電動(dong)(dong)(dong)機(ji)工作(zuo)(zuo)在電動(dong)(dong)(dong)機(ji)狀況時，轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)小于(yu)同步轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)。為(wei)了描繪轉(zhuan)(zhuan)(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)n與同步轉(zhuan)(zhuan)(zhuan)(zhuan)速(su)(su)(su)n1之間的(de)差別，引入轉(zhuan)(zhuan)(zhuan)(zhuan)差率(lv)(slip)。
