微型空心杯直流電機原理與應用

空心(xin)杯(bei)(bei)轉(zhuan)(zhuan)子(zi)(zi)結構解(jie)決(jue)了傳統鐵(tie)芯電機(ji)因(yin)鐵(tie)芯形成(cheng)渦(wo)流(liu)而造(zao)成(cheng)的(de)(de)電能(neng)損(sun)耗，并(bing)且重量和轉(zhuan)(zhuan)動(dong)慣量也大(da)幅度的(de)(de)降低，減少(shao)轉(zhuan)(zhuan)子(zi)(zi)的(de)(de)機(ji)械能(neng)損(sun)耗。空心(xin)杯(bei)(bei)轉(zhuan)(zhuan)子(zi)(zi)結構使(shi)微型電機(ji)的(de)(de)運轉(zhuan)(zhuan)特(te)性得到了極(ji)大(da)的(de)(de)改善。空心(xin)杯(bei)(bei)微型直流(liu)電機(ji)是由(you)機(ji)殼、線(xian)圈、磁(ci)體、后蓋及(ji)換向器組成(cheng)，它的(de)(de)線(xian)圈看起來(lai)就(jiu)像(xiang)一(yi)個水杯(bei)(bei)，所(suo)以(yi)稱之為(wei)“空心(xin)杯(bei)(bei)電機(ji)”，因(yin)為(wei)沒(mei)(mei)有鐵(tie)芯，所(suo)以(yi)沒(mei)(mei)有鐵(tie)損(sun)，效率高(gao)。線(xian)圈作為(wei)轉(zhuan)(zhuan)子(zi)(zi)，轉(zhuan)(zhuan)動(dong)慣量小，好控制，效率高(gao)。轉(zhuan)(zhuan)子(zi)(zi)線(xian)圈只能(neng)做得很薄，否則會損(sun)失磁(ci)通，所(suo)以(yi)空心(xin)杯(bei)(bei)電機(ji)功率一(yi)般做不大(da)，大(da)幾(ji)百瓦(wa)。

優(you)缺(que)點對比(bi)：鐵芯(xin)電(dian)(dian)(dian)(dian)機(ji)和(he)(he)空(kong)心(xin)杯(bei)電(dian)(dian)(dian)(dian)機(ji)，其中(zhong)(zhong)空(kong)心(xin)杯(bei)電(dian)(dian)(dian)(dian)機(ji)具(ju)有(you)(you)(you)(you)效率高(gao)、電(dian)(dian)(dian)(dian)流小、成本低的優(you)點，但(dan)是由于空(kong)心(xin)杯(bei)電(dian)(dian)(dian)(dian)機(ji)設計初期各方(fang)面的局限性，空(kong)心(xin)杯(bei)電(dian)(dian)(dian)(dian)機(ji)無法焊接(jie)壓(ya)(ya)敏(min)電(dian)(dian)(dian)(dian)阻(zu)的，并一直延(yan)續到現(xian)在，導致其有(you)(you)(you)(you)壽命(ming)短和(he)(he)噪(zao)音差的缺(que)點。而鐵芯(xin)馬達由于有(you)(you)(you)(you)壓(ya)(ya)敏(min)電(dian)(dian)(dian)(dian)阻(zu)，所以其壽命(ming)比(bi)空(kong)心(xin)杯(bei)電(dian)(dian)(dian)(dian)機(ji)長，噪(zao)音也好些(xie)。壓(ya)(ya)敏(min)電(dian)(dian)(dian)(dian)阻(zu)具(ju)有(you)(you)(you)(you)過濾浪涌電(dian)(dian)(dian)(dian)壓(ya)(ya)的作(zuo)用，即(ji)可以減少電(dian)(dian)(dian)(dian)機(ji)運轉過程(cheng)中(zhong)(zhong)換向器與電(dian)(dian)(dian)(dian)刷間的電(dian)(dian)(dian)(dian)火(huo)花的產生，延(yan)長電(dian)(dian)(dian)(dian)機(ji)的壽命(ming)的同時可以降(jiang)低電(dian)(dian)(dian)(dian)機(ji)的電(dian)(dian)(dian)(dian)氣噪(zao)音。
