同步電動機分類

    同步電動機分類

    同步電動機在結構上大致有兩種：

    轉子用直流電進行勵磁

    它(ta)的(de)轉(zhuan)子(zi)做(zuo)成(cheng)顯(xian)極(ji)式(shi)的(de)，安(an)裝(zhuang)在(zai)磁(ci)極(ji)鐵(tie)芯(xin)上(shang)麵(mian)的(de)磁(ci)場(chang)線(xian)圈(quan)是(shi)相(xiang)互(hu)串(chuan)聯(lian)的(de)，接(jie)成(cheng)具(ju)有(you)交(jiao)替(ti)相(xiang)反(fan)的(de)極(ji)性(xing)，並(bing)有(you)兩(liang)根(gen)引(yin)線(xian)連(lian)接(jie)到(dao)裝(zhuang)在(zai)軸(zhou)上(shang)的(de)兩(liang)隻(zhi)滑(hua)環(huan)上(shang)麵(mian)。磁(ci)場(chang)線(xian)圈(quan)是(shi)由(you)一(yi)隻(zhi)小(xiao)型(xing)直(zhi)流(liu)發(fa)電(dian)機(ji)或(huo)蓄(xu)電(dian)池(chi)來(lai)激(ji)勵(li)，在(zai)大(da)多(duo)數(shu)同(tong)步(bu)電(dian)動(dong)機(ji)中(zhong)
，直(zhi)流(liu)發(fa)電(dian)機(ji)是(shi)裝(zhuang)在(zai)電(dian)動(dong)機(ji)軸(zhou)上(shang)的(de)，用(yong)以(yi)供(gong)應(ying)轉(zhuan)子(zi)磁(ci)極(ji)線(xian)圈(quan)的(de)勵(li)磁(ci)電(dian)流(liu)。

    由you於yu這zhe種zhong同tong步bu電dian動dong機ji不bu能neng自zi動dong啟qi動dong，所suo以yi在zai轉zhuan子zi上shang還hai裝zhuang有you鼠shu籠long式shi繞rao組zu而er作zuo為wei電dian動dong機ji啟qi動dong之zhi用yong。鼠shu籠long繞rao組zu放fang在zai轉zhuan子zi的de周zhou圍wei，結jie構gou與yu異yi步bu電dian動dong機ji相xiang似si。
