電動牙刷電機也稱為電動牙刷馬達、齒(chi)輪(lun)箱，用于(yu)智能電(dian)(dian)動(dong)牙刷上(shang)的(de)(de)動(dong)力(li)驅動(dong)裝置；這(zhe)類(lei)微型(xing)減速電(dian)(dian)機屬于(yu)非(fei)品，根據電(dian)(dian)動(dong)牙刷的(de)(de)參數定制而成，電(dian)(dian)壓通常在24v以下，直徑尺寸38mm以下，電(dian)(dian)機齒(chi)輪(lun)箱驅動(dong)結構(gou)材質分別采用塑膠、金屬制造(zao)而成；目前主(zhu)流的(de)(de)驅動(dong)方式分為(wei)：

  ①有齒輪的傳統(tong)電機動力輸出系統(tong)——微型電機；

  ②非齒(chi)輪動力(li)輸出系(xi)統——磁懸動力(li)系(xi)統（MTIC）；
