無刷電機(ji)(ji)控制器的(de)結構組成(cheng)：1、磁(ci)(ci)(ci)鐵：是(shi)(shi)安裝(zhuang)在轉(zhuan)(zhuan)子上(shang)，是(shi)(shi)無刷電機(ji)(ji)的(de)重要組成(cheng)部(bu)分(fen)，無刷電機(ji)(ji)的(de)絕(jue)大部(bu)分(fen)性能參數都與(yu)磁(ci)(ci)(ci)鐵相(xiang)關(guan)，包(bao)括(kuo)功率、轉(zhuan)(zhuan)速(su)、扭矩(ju)等。2、硅鋼(gang)片：是(shi)(shi)有槽(cao)無刷電機(ji)(ji)的(de)重要組成(cheng)部(bu)分(fen)，上(shang)饒交流控制器，當然，交流控制器生產商，無槽(cao)無刷電機(ji)(ji)是(shi)(shi)沒有硅鋼(gang)片的(de)，但是(shi)(shi)目(mu)前(qian)絕(jue)大多數的(de)無刷電機(ji)(ji)都是(shi)(shi)有槽(cao)的(de)。它(ta)在整個系統(tong)中的(de)作用主要是(shi)(shi)降低磁(ci)(ci)(ci)阻、參與(yu)磁(ci)(ci)(ci)路運轉(zhuan)(zhuan)。

無刷直流永(yong)磁(ci)電(dian)(dian)(dian)(dian)動機(ji)實現正反(fan)轉(zhuan)(zhuan)的(de)(de)方(fang)法(fa)有兩(liang)種：1、裝(zhuang)置(zhi)兩(liang)套轉(zhuan)(zhuan)子(zi)(zi)(zi)位置(zhi)傳(chuan)感器(qi)。2、采用一套轉(zhuan)(zhuan)子(zi)(zi)(zi)位置(zhi)傳(chuan)感器(qi)，通(tong)過控制(zhi)定(ding)子(zi)(zi)(zi)繞組的(de)(de)換相次序來改變(bian)電(dian)(dian)(dian)(dian)機(ji)轉(zhuan)(zhuan)動方(fang)向。由(you)于三個位置(zhi)傳(chuan)感器(qi)隨著轉(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)轉(zhuan)(zhuan)動，交流控制(zhi)器(qi)詳情，會依次導(dao)通(tong)，使(shi)(shi)得對(dui)應的(de)(de)相線圈(quan)也依次通(tong)電(dian)(dian)(dian)(dian)，從而定(ding)子(zi)(zi)(zi)產生的(de)(de)磁(ci)場方(fang)向也不(bu)斷(duan)地變(bian)化，電(dian)(dian)(dian)(dian)機(ji)轉(zhuan)(zhuan)子(zi)(zi)(zi)也跟著轉(zhuan)(zhuan)動起來，這就是無刷直流電(dian)(dian)(dian)(dian)機(ji)的(de)(de)基本轉(zhuan)(zhuan)動原理——檢測轉(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)位置(zhi)，依次給各相通(tong)電(dian)(dian)(dian)(dian)，交流控制(zhi)器(qi)報價(jia)，使(shi)(shi)定(ding)子(zi)(zi)(zi)產生的(de)(de)磁(ci)場的(de)(de)方(fang)向連續(xu)均勻地變(bian)化。
