步進電機和無刷電機區(qu)別

步(bu)進(jin)(jin)電(dian)(dian)機(ji)(ji)和(he)無(wu)刷(shua)電(dian)(dian)機(ji)(ji)是兩(liang)種(zhong)應(ying)用非常(chang)廣(guang)泛的(de)(de)驅動(dong)(dong)電(dian)(dian)機(ji)(ji)，兩(liang)者的(de)(de)結(jie)構、領域、驅動(dong)(dong)特性上明顯(xian)不一樣，下面詳細介紹步(bu)進(jin)(jin)電(dian)(dian)機(ji)(ji)和(he)無(wu)刷(shua)電(dian)(dian)機(ji)(ji)的(de)(de)區別(bie)，將從驅動(dong)(dong)原理、特點、應(ying)用場景(jing)介紹。步(bu)進(jin)(jin)電(dian)(dian)機(ji)(ji)又稱為(wei)脈(mo)沖(chong)電(dian)(dian)機(ji)(ji)，基于最(zui)基本的(de)(de)電(dian)(dian)磁(ci)鐵原理，它是一種(zhong)可以(yi)自由回轉(zhuan)(zhuan)的(de)(de)電(dian)(dian)磁(ci)鐵，其動(dong)(dong)作原理是依靠(kao)氣(qi)隙(xi)磁(ci)導(dao)的(de)(de)變化來產(chan)生(sheng)電(dian)(dian)磁(ci)轉(zhuan)(zhuan)矩。步(bu)進(jin)(jin)電(dian)(dian)機(ji)(ji)是一種(zhong)將電(dian)(dian)脈(mo)沖(chong)信號(hao)轉(zhuan)(zhuan)換成相應(ying)角(jiao)位(wei)移(yi)或線(xian)位(wei)移(yi)的(de)(de)電(dian)(dian)動(dong)(dong)機(ji)(ji)。每(mei)輸入(ru)一個(ge)脈(mo)沖(chong)信號(hao)，轉(zhuan)(zhuan)子就轉(zhuan)(zhuan)動(dong)(dong)一個(ge)角(jiao)度或前進(jin)(jin)一步(bu)，其輸出的(de)(de)角(jiao)位(wei)移(yi)或線(xian)位(wei)移(yi)與(yu)輸入(ru)的(de)(de)脈(mo)沖(chong)數(shu)成正(zheng)比，轉(zhuan)(zhuan)速與(yu)脈(mo)沖(chong)頻(pin)率成正(zheng)比。因此，步(bu)進(jin)(jin)電(dian)(dian)動(dong)(dong)機(ji)(ji)又稱脈(mo)沖(chong)電(dian)(dian)動(dong)(dong)機(ji)(ji)。通常(chang)電(dian)(dian)機(ji)(ji)的(de)(de)轉(zhuan)(zhuan)子為(wei)永磁(ci)體，當電(dian)(dian)......
