工業大風扇目前(qian)廣泛應用(yong)于很(hen)多(duo)公共(gong)場所，比如，在很(hen)多(duo)車(che)間里面使用(yong)它發揮了重要的(de)作用(yong)。用(yong)于空氣流通和冷卻，現有風(feng)扇(shan)一般采用(yong)交流電(dian)容電(dian)機，同時采用(yong)電(dian)感(gan)或電(dian)容降壓(ya)的(de)方式(shi)調速，造成(cheng)體積(ji)大、功(gong)(gong)耗高，電(dian)機產生大量熱量，使用(yong)壽命短，且風(feng)機葉(xie)片調速范圍窄(zhai)。今(jin)天，我們就帶(dai)大家了解(jie)一下工業大風(feng)扇(shan)的(de)功(gong)(gong)能。

　　一(yi)種類型的(de)(de)風扇，包(bao)括設置在(zai)外殼內的(de)(de)驅(qu)動(dong)(dong)裝(zhuang)置，驅(qu)動(dong)(dong)葉片旋轉。所述驅(qu)動(dong)(dong)裝(zhuang)置包(bao)括用(yong)于驅(qu)動(dong)(dong)葉片旋轉的(de)(de)定子(zi)和轉子(zi)。該驅(qu)動(dong)(dong)裝(zhuang)置還包(bao)括直流無刷(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)、感應電(dian)(dian)(dian)(dian)機(ji)(ji)電(dian)(dian)(dian)(dian)壓感應電(dian)(dian)(dian)(dian)路(lu)，該電(dian)(dian)(dian)(dian)路(lu)的(de)(de)電(dian)(dian)(dian)(dian)流或電(dian)(dian)(dian)(dian)壓變化控制(zhi)定子(zi)上繞組的(de)(de)通電(dian)(dian)(dian)(dian)或斷(duan)電(dian)(dian)(dian)(dian)以及通電(dian)(dian)(dian)(dian)和斷(duan)電(dian)(dian)(dian)(dian)的(de)(de)脈寬(kuan)開關電(dian)(dian)(dian)(dian)路(lu)。

　　感(gan)(gan)應(ying)電(dian)路主要由位置傳感(gan)(gan)器(qi)、感(gan)(gan)應(ying)線圈和直流無刷電(dian)機驅動的(de)磁塊(kuai)組成(cheng)。傳感(gan)(gan)器(qi)感(gan)(gan)應(ying)線圈和磁塊(kuai)形成(cheng)的(de)磁場發生變化，控制開關電(dian)路通(tong)電(dian)或斷電(dian)。

　　所(suo)述直流(liu)無刷(shua)電機連(lian)接到將交(jiao)流(liu)電源轉(zhuan)換(huan)為直流(liu)電源的功率(lv)(lv)轉(zhuan)換(huan)器，并且所(suo)述功率(lv)(lv)轉(zhuan)換(huan)器同(tong)時連(lian)接到交(jiao)流(liu)輸入功率(lv)(lv)，工業大風扇(shan)殼(ke)體由上(shang)(shang)殼(ke)體和擰在上(shang)(shang)殼(ke)體上(shang)(shang)的底(di)殼(ke)組成。
