無刷減速電機的結構及應用范圍

   無刷直流電機是由電(dian)動(dong)(dong)機(ji)(ji)主體和傳(chuan)動(dong)(dong)器組(zu)成(cheng)(cheng)，是一(yi)種的(de)機(ji)(ji)電(dian)一(yi)體化產品。電(dian)動(dong)(dong)機(ji)(ji)的(de)定子(zi)繞組(zu)成(cheng)(cheng)三(san)相星形接法，電(dian)動(dong)(dong)機(ji)(ji)的(de)轉(zhuan)子(zi)上粘(zhan)有(you)已充磁(ci)的(de)永(yong)磁(ci)體，目前采用(yong)(yong)的(de)永(yong)磁(ci)材料(liao)主要含有(you)鐵(tie)淦(gan)氧﹑鋁鎳鈷﹑釹鐵(tie)硼等(deng)，根據幾(ji)種的(de)磁(ci)感(gan)應強度(du)和磁(ci)場強度(du)成(cheng)(cheng)線性關系(xi)這一(yi)特點(dian)，應用(yong)(yong)為(wei)的(de)就是釹鐵(tie)硼（Nd-Fe-B）。它(ta)的(de)線性關系(xi)范圍大，被稱為(wei)第三(san)代稀土永(yong)磁(ci)合金(jin)。為(wei)了檢測(ce)電(dian)動(dong)(dong)轉(zhuan)子(zi)的(de)性，在電(dian)動(dong)(dong)機(ji)(ji)內(nei)裝有(you)位置傳(chuan)感(gan)器。傳(chuan)動(dong)(dong)器由功(gong)率(lv)電(dian)子(zi)器件和集成(cheng)(cheng)電(dian)路等(deng)構成(cheng)(cheng)，其功(gong)能是：控制電(dian)動(dong)(dong)機(ji)(ji)的(de)啟動(dong)(dong)﹑停(ting)止﹑變(bian)速及正反轉(zhuan)并提供保護和顯示等(deng)等(deng)。 

   無刷(shua)直(zhi)流電(dian)(dian)(dian)(dian)機(ji)是一種用途的(de)(de)電(dian)(dian)(dian)(dian)機(ji)，在(zai)普通的(de)(de)直(zhi)流電(dian)(dian)(dian)(dian)機(ji)、伺服電(dian)(dian)(dian)(dian)機(ji)和力矩電(dian)(dian)(dian)(dian)機(ji)的(de)(de)使(shi)用中，以(yi)及在(zai)電(dian)(dian)(dian)(dian)子(zi)(zi)設(she)備、機(ji)器人、航空航天技(ji)術、數控裝置(zhi)、化工(gong)等領域中都(dou)有(you)著(zhu)(zhu)不俗的(de)(de)表現(xian)，同時其傳動(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)設(she)計吸收了當(dang)今專用集(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)穩(wen)定、的(de)(de)特點，在(zai)國民(min)生(sheng)產和生(sheng)活中起著(zhu)(zhu)巨(ju)大的(de)(de)作用。在(zai)設(she)計中，本著(zhu)(zhu)既能傳動(dong)(dong)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)功能的(de)(de)良好實現(xian)，也能使(shi)得整套電(dian)(dian)(dian)(dian)子(zi)(zi)控制(zhi)線路(lu)(lu)(lu)(lu)結構簡單、運(yun)行可靠、成(cheng)本低(di)廉的(de)(de)思路(lu)(lu)(lu)(lu)，選擇合適的(de)(de)模擬元件和專用電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)控制(zhi)集(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)芯片(pian)，比較分析優化電(dian)(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)結構。另(ling)，無刷(shua)電(dian)(dian)(dian)(dian)機(ji)以(yi)電(dian)(dian)(dian)(dian)子(zi)(zi)換向取代機(ji)械換向，無機(ji)械摩擦，無磨損，無電(dian)(dian)(dian)(dian)火花，免維護且能做到更加密(mi)封等特點所以(yi)技(ji)術上要優于有(you)刷(shua)電(dian)(dian)(dian)(dian)機(ji)。
