微型空心杯直流電機原理與應用

空(kong)(kong)(kong)心(xin)(xin)杯(bei)(bei)轉(zhuan)子(zi)結(jie)構解決了傳統(tong)鐵(tie)芯(xin)電(dian)(dian)機(ji)(ji)(ji)因鐵(tie)芯(xin)形(xing)成渦流而造成的(de)電(dian)(dian)能(neng)損耗，并且重量(liang)和轉(zhuan)動(dong)慣量(liang)也(ye)大(da)(da)幅度的(de)降低，減少轉(zhuan)子(zi)的(de)機(ji)(ji)(ji)械能(neng)損耗。空(kong)(kong)(kong)心(xin)(xin)杯(bei)(bei)轉(zhuan)子(zi)結(jie)構使微型電(dian)(dian)機(ji)(ji)(ji)的(de)運(yun)轉(zhuan)特性得(de)到(dao)了極大(da)(da)的(de)改善。空(kong)(kong)(kong)心(xin)(xin)杯(bei)(bei)微型直流電(dian)(dian)機(ji)(ji)(ji)是(shi)由(you)機(ji)(ji)(ji)殼、線圈(quan)(quan)、磁(ci)體、后蓋及換向(xiang)器組成，它的(de)線圈(quan)(quan)看起來就像一(yi)個水杯(bei)(bei)，所以(yi)(yi)稱之為(wei)“空(kong)(kong)(kong)心(xin)(xin)杯(bei)(bei)電(dian)(dian)機(ji)(ji)(ji)”，因為(wei)沒有鐵(tie)芯(xin)，所以(yi)(yi)沒有鐵(tie)損，效(xiao)率(lv)高(gao)。線圈(quan)(quan)作(zuo)為(wei)轉(zhuan)子(zi)，轉(zhuan)動(dong)慣量(liang)小，好(hao)控制，效(xiao)率(lv)高(gao)。轉(zhuan)子(zi)線圈(quan)(quan)只能(neng)做得(de)很薄(bo)，否則會損失(shi)磁(ci)通(tong)，所以(yi)(yi)空(kong)(kong)(kong)心(xin)(xin)杯(bei)(bei)電(dian)(dian)機(ji)(ji)(ji)功(gong)率(lv)一(yi)般做不大(da)(da)，大(da)(da)幾百瓦。

優缺點對比(bi)：鐵(tie)芯電(dian)(dian)(dian)機(ji)(ji)(ji)和(he)空(kong)(kong)(kong)心(xin)杯(bei)電(dian)(dian)(dian)機(ji)(ji)(ji)，其(qi)中(zhong)(zhong)空(kong)(kong)(kong)心(xin)杯(bei)電(dian)(dian)(dian)機(ji)(ji)(ji)具有(you)效(xiao)率高、電(dian)(dian)(dian)流小、成本低的(de)(de)優點，但是由于空(kong)(kong)(kong)心(xin)杯(bei)電(dian)(dian)(dian)機(ji)(ji)(ji)設計(ji)初期(qi)各方面的(de)(de)局限性，空(kong)(kong)(kong)心(xin)杯(bei)電(dian)(dian)(dian)機(ji)(ji)(ji)無(wu)法焊(han)接壓敏(min)電(dian)(dian)(dian)阻(zu)的(de)(de)，并(bing)一直延續到(dao)現在，導致其(qi)有(you)壽(shou)命短和(he)噪(zao)(zao)音(yin)差(cha)的(de)(de)缺點。而鐵(tie)芯馬(ma)達由于有(you)壓敏(min)電(dian)(dian)(dian)阻(zu)，所以(yi)其(qi)壽(shou)命比(bi)空(kong)(kong)(kong)心(xin)杯(bei)電(dian)(dian)(dian)機(ji)(ji)(ji)長，噪(zao)(zao)音(yin)也好些。壓敏(min)電(dian)(dian)(dian)阻(zu)具有(you)過濾浪涌電(dian)(dian)(dian)壓的(de)(de)作用，即可以(yi)減少電(dian)(dian)(dian)機(ji)(ji)(ji)運轉(zhuan)過程中(zhong)(zhong)換向器與(yu)電(dian)(dian)(dian)刷間(jian)的(de)(de)電(dian)(dian)(dian)火花的(de)(de)產生，延長電(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)壽(shou)命的(de)(de)同(tong)時可以(yi)降低電(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)電(dian)(dian)(dian)氣噪(zao)(zao)音(yin)。
