電磁調速電機具有，無級調速、調速控制簡單、調速平滑、啟動轉矩大等優點，今天山東盛華電機生產廠家就帶大(da)家了(le)解一下，電磁調速(su)電機(ji)是如何實現無級調速(su)的。

電(dian)滋(zi)變頻調速減速機的基本點是電(dian)滋(zi)轉(zhuan)差剎車，正負相放置、N極(ji)和(he)S極(ji)交替分布的爪極(ji)在異步(bu)電(dian)機的拖動(dong)下(xia)(xia)旋轉(zhuan)，實(shi)心電(dian)樞(shu)切割(ge)磁(ci)力線感應出(chu)渦流(liu)電(dian)流(liu)，在爪極(ji)磁(ci)場的作(zuo)用(yong)下(xia)(xia)旋轉(zhuan)，帶動(dong)輸出(chu)軸(zhou)輸出(chu)機械功率(lv)。

調(diao)(diao)(diao)接(jie)爪極(ji)勵(li)磁(ci)(ci)調(diao)(diao)(diao)接(jie)器(qi)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流量規(gui)格，就(jiu)就(jiu)可(ke)以調(diao)(diao)(diao)接(jie)電(dian)(dian)(dian)(dian)磁(ci)(ci)效應電(dian)(dian)(dian)(dian)場(chang)強(qiang)度(du)與爪極(ji)電(dian)(dian)(dian)(dian)場(chang)強(qiang)度(du)藕合度(du)甚至說流速(su)(su)差，若想來(lai)保(bao)證 調(diao)(diao)(diao)速(su)(su)器(qi)。若方形電(dian)(dian)(dian)(dian)樞與爪極(ji)電(dian)(dian)(dian)(dian)場(chang)強(qiang)度(du)的(de)拖動(dong)流速(su)(su)此次，都不(bu)將會(hui)感器(qi)出電(dian)(dian)(dian)(dian)磁(ci)(ci)效應電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流量，方形電(dian)(dian)(dian)(dian)樞拋棄拖動(dong)的(de)原(yuan)原(yuan)因(yin)—電(dian)(dian)(dian)(dian)磁(ci)(ci)力，故此又稱之為電(dian)(dian)(dian)(dian)磁(ci)(ci)滑差調(diao)(diao)(diao)速(su)(su)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)。不(bu)難想象(xiang)，該類電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)為組(zu)合式結構，主(zhu)要由拖動(dong)電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)、電(dian)(dian)(dian)(dian)磁(ci)(ci)轉差離(li)合器(qi)和測(ce)速(su)(su)發電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)組(zu)成，測(ce)速(su)(su)發電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)將轉速(su)(su)信(xin)號反饋給控制(zhi)器(qi)，與控制(zhi)器(qi)設定的(de)轉速(su)(su)比較，發出調(diao)(diao)(diao)高或調(diao)(diao)(diao)低實心電(dian)(dian)(dian)(dian)樞轉速(su)(su)的(de)指令。
