無刷電機和普通電機區別？

無刷電機和(he)普通(tong)電(dian)(dian)(dian)(dian)機(ji)是兩種(zhong)常(chang)用的驅(qu)動電(dian)(dian)(dian)(dian)機(ji)，無刷電(dian)(dian)(dian)(dian)機(ji)屬于直流電(dian)(dian)(dian)(dian)機(ji)一種(zhong)，廣泛應用在電(dian)(dian)(dian)(dian)子(zi)產品設備、智能(neng)家居、機(ji)械設備、智能(neng)機(ji)器人(ren)、個人(ren)護理設備、醫療機(ji)械設備等(deng)領域。兆威機(ji)電(dian)(dian)(dian)(dian)股份有(you)限公司致力于研發、制造(zao)無刷減速(su)電(dian)(dian)(dian)(dian)機(ji)，下面詳細介(jie)紹了(le)無刷電(dian)(dian)(dian)(dian)機(ji)和(he)普通(tong)電(dian)(dian)(dian)(dian)機(ji)兩種(zhong)驅(qu)動電(dian)(dian)(dian)(dian)機(ji)性能(neng)、特點。

無刷(shua)電(dian)(dian)(dian)機(ji)(ji)(ji)：無刷(shua)直流(liu)(liu)電(dian)(dian)(dian)機(ji)(ji)(ji)由(you)電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)主體和驅動(dong)器組成，是一種(zhong)典型(xing)的(de)(de)(de)機(ji)(ji)(ji)電(dian)(dian)(dian)一體化產品。由(you)于無刷(shua)直流(liu)(liu)電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)是以自控式(shi)(shi)運行(xing)(xing)的(de)(de)(de)，所以不會(hui)像變(bian)(bian)頻調(diao)速下重載(zai)啟動(dong)的(de)(de)(de)同(tong)步電(dian)(dian)(dian)機(ji)(ji)(ji)那樣在(zai)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)上(shang)另加(jia)啟動(dong)繞(rao)組，也不會(hui)在(zai)負載(zai)突變(bian)(bian)時產生振(zhen)蕩和失(shi)步。無刷(shua)直流(liu)(liu)電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)是采用(yong)半導體開關器件(jian)(jian)來實現電(dian)(dian)(dian)子(zi)(zi)換(huan)向(xiang)的(de)(de)(de)，即用(yong)電(dian)(dian)(dian)子(zi)(zi)開關器件(jian)(jian)代替傳統的(de)(de)(de)接觸式(shi)(shi)換(huan)向(xiang)器和電(dian)(dian)(dian)刷(shua)。它具有(you)可(ke)靠性高(gao)(gao)、無換(huan)向(xiang)火花、機(ji)(ji)(ji)械噪聲低等(deng)優點，廣泛(fan)應用(yong)于高(gao)(gao)檔錄音座(zuo)、錄像機(ji)(ji)(ji)、電(dian)(dian)(dian)子(zi)(zi)儀器及自動(dong)化辦公(gong)設備中(zhong)。無刷(shua)直流(liu)(liu)電(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)由(you)永磁(ci)體轉(zhuan)(zhuan)(zhuan)子(zi)(zi)、多極繞(rao)組定(ding)(ding)(ding)子(zi)(zi)、位置(zhi)傳感(gan)器等(deng)組成。位置(zhi)傳感(gan)按轉(zhuan)(zhuan)(zhuan)子(zi)(zi)位置(zhi)的(de)(de)(de)變(bian)(bian)化，沿著(zhu)一定(ding)(ding)(ding)次序對定(ding)(ding)(ding)子(zi)(zi)繞(rao)組的(de)(de)(de)電(dian)(dian)(dian)流(liu)(liu)進行(xing)(xing)換(huan)流(liu)(liu)（即檢測轉(zhuan)(zhuan)(zhuan)子(zi)(zi)磁(ci)極相對定(ding)(ding)(ding)子(zi)(zi)繞(rao)組的(de)(de)(de)位置(zhi)，并在(zai)確定(ding)(ding)(ding)的(de)(de)(de)位置(zhi)處產生位置(zhi)傳感(gan)信號，經(jing)信號轉(zhuan)(zhuan)(zhuan)換(huan)電(dian)(dian)(dian)路處理后去控制功率開關電(dian)(dian)(dian)路，按一定(ding)(ding)(ding)的(de)(de)(de)邏輯關系進行(xing)(xing)繞(rao)組電(dian)(dian)(dian)流(liu)(liu)切換(huan)）。

無刷(shua)電(dian)機優點：無電(dian)刷(shua)、低干擾、噪音低、運轉(zhuan)順暢(chang)、壽命長、低維護成本；

無刷電(dian)機(ji)缺點：摩(mo)擦大(da)(da)、損(sun)耗大(da)(da)、發熱大(da)(da)、壽命(ming)短(duan)、效率(lv)低(di)、輸出功率(lv)小；

無刷電機：通常被使用(yong)在控制要求比較高，轉(zhuan)(zhuan)速比較高的設備(bei)上，如航模，精密儀器儀表(biao)等對(dui)電機轉(zhuan)(zhuan)速控制嚴格，轉(zhuan)(zhuan)速達到很高的設備(bei)上。
