美國(guo)利森LEESON電動機的工作(zuo)原理及分類

公(gong)司(si)歐(ou)美進口設(she)備優(you)勢：

1）直接從(cong)廠家采(cai)購，保證所有(you)產(chan)品均為原裝。

2）價(jia)格(ge)合理(li)，繞過層層代理(li)，大限度的讓利給客(ke)戶。

3）渠道廣(guang)泛，國內有(you)代理，或者有(you)客戶保護(hu)廠家不賣的產品，只要您(nin)能提供型號，我們同(tong)樣可(ke)以從各(ge)國的分銷商來(lai)采購。

由于我公司與德(de)國各制造(zao)廠(chang)商(shang)合作已久(jiu)，成交量大，進貨價要比(bi)您從這(zhe)些制造(zao)商(shang)或這(zhe)些廠(chang)商(shang)在亞洲的代理那里直(zhi)接購(gou)買要便(bian) 宜得多。我公司買賣手(shou)續(xu)的辦理及交貨的時間堪稱* ，速度(du)之快(kuai)效率之高，客戶(hu)贊譽極多。

電(dian)動(dong)機的工作原理(li)主要是(shi)基于磁(ci)場和(he)電(dian)流的相互作用，通過磁(ci)場和(he)電(dian)流的變化，將(jiang)電(dian)能轉(zhuan)換為機械能，讓電(dian)動(dong)機轉(zhuan)動(dong)。

電動機的分類可以(yi)從不同的角度進行分類，以(yi)下(xia)是一(yi)些常見(jian)的分類方式：

    按(an)起(qi)(qi)動(dong)(dong)與運(yun)行方式分類：電(dian)動(dong)(dong)機(ji)可(ke)以(yi)分為電(dian)容起(qi)(qi)動(dong)(dong)式單(dan)相(xiang)異(yi)步電(dian)動(dong)(dong)機(ji)、電(dian)容運(yun)轉(zhuan)式單(dan)相(xiang)異(yi)步電(dian)動(dong)(dong)機(ji)、電(dian)容起(qi)(qi)動(dong)(dong)運(yun)轉(zhuan)式單(dan)相(xiang)異(yi)步電(dian)動(dong)(dong)機(ji)和三相(xiang)異(yi)步電(dian)動(dong)(dong)機(ji)。
