微型空心杯直流電機原理與應用

空(kong)(kong)心(xin)杯(bei)(bei)(bei)轉(zhuan)(zhuan)子結(jie)構解決(jue)了傳(chuan)統鐵芯電(dian)(dian)機(ji)因(yin)鐵芯形成(cheng)渦流而(er)造成(cheng)的(de)(de)(de)(de)(de)(de)電(dian)(dian)能(neng)損耗，并且(qie)重量和轉(zhuan)(zhuan)動慣量也大(da)幅度的(de)(de)(de)(de)(de)(de)降低，減少轉(zhuan)(zhuan)子的(de)(de)(de)(de)(de)(de)機(ji)械能(neng)損耗。空(kong)(kong)心(xin)杯(bei)(bei)(bei)轉(zhuan)(zhuan)子結(jie)構使微型電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)(de)運(yun)轉(zhuan)(zhuan)特(te)性得到了極大(da)的(de)(de)(de)(de)(de)(de)改善。空(kong)(kong)心(xin)杯(bei)(bei)(bei)微型直(zhi)流電(dian)(dian)機(ji)是(shi)由機(ji)殼、線圈(quan)(quan)、磁體、后蓋及換向(xiang)器組成(cheng)，它(ta)的(de)(de)(de)(de)(de)(de)線圈(quan)(quan)看起來就像一個(ge)水杯(bei)(bei)(bei)，所(suo)(suo)以稱之為“空(kong)(kong)心(xin)杯(bei)(bei)(bei)電(dian)(dian)機(ji)”，因(yin)為沒有鐵芯，所(suo)(suo)以沒有鐵損，效(xiao)率(lv)高(gao)。線圈(quan)(quan)作為轉(zhuan)(zhuan)子，轉(zhuan)(zhuan)動慣量小，好控(kong)制，效(xiao)率(lv)高(gao)。轉(zhuan)(zhuan)子線圈(quan)(quan)只能(neng)做(zuo)得很薄，否則會(hui)損失(shi)磁通，所(suo)(suo)以空(kong)(kong)心(xin)杯(bei)(bei)(bei)電(dian)(dian)機(ji)功(gong)率(lv)一般做(zuo)不大(da)，大(da)幾百瓦。

優缺點對比：鐵芯(xin)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)和空(kong)(kong)心(xin)杯(bei)(bei)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，其(qi)中(zhong)空(kong)(kong)心(xin)杯(bei)(bei)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)具有(you)(you)效率高、電(dian)(dian)(dian)(dian)流(liu)小(xiao)、成本低的(de)(de)(de)優點，但是由(you)于空(kong)(kong)心(xin)杯(bei)(bei)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)設(she)計初期各方面的(de)(de)(de)局限(xian)性，空(kong)(kong)心(xin)杯(bei)(bei)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)無法(fa)焊接(jie)壓(ya)敏(min)(min)電(dian)(dian)(dian)(dian)阻的(de)(de)(de)，并一直延續到(dao)現在，導致其(qi)有(you)(you)壽命短和噪音差的(de)(de)(de)缺點。而鐵芯(xin)馬達由(you)于有(you)(you)壓(ya)敏(min)(min)電(dian)(dian)(dian)(dian)阻，所以其(qi)壽命比空(kong)(kong)心(xin)杯(bei)(bei)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)長(chang)，噪音也好些。壓(ya)敏(min)(min)電(dian)(dian)(dian)(dian)阻具有(you)(you)過濾浪涌(yong)電(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)作用，即(ji)可(ke)以減(jian)少電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)運轉過程(cheng)中(zhong)換(huan)向器與電(dian)(dian)(dian)(dian)刷間的(de)(de)(de)電(dian)(dian)(dian)(dian)火花的(de)(de)(de)產(chan)生，延長(chang)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)壽命的(de)(de)(de)同(tong)時可(ke)以降低電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)電(dian)(dian)(dian)(dian)氣噪音。
