伺服電機與減速機是老搭檔了，伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)有不同的(de)種類。伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)定子是永磁(ci)的(de)就(jiu)是有刷(shua)(shua)直流(liu)永磁(ci)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)，伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)轉子是永磁(ci)的(de)就(jiu)是無刷(shua)(shua)直流(liu)永磁(ci)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)或(huo)永磁(ci)同步電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)。有刷(shua)(shua)直流(liu)永磁(ci)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)不需要換相電(dian)(dian)(dian)(dian)(dian)(dian)路（逆變器），無刷(shua)(shua)永磁(ci)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)需要換相電(dian)(dian)(dian)(dian)(dian)(dian)路。

伺服電子轉子帶磁性，三個繞組若閉(bi)合就會形成(cheng)電磁效應，自然會鎖死(si)。如(ru)果繞組沒有(you)形成(cheng)閉(bi)合，不是抱閘(zha)鎖死(si)就是轉子遇到(dao)故(gu)障堵轉。

那(nei)么伺(si)服(fu)(fu)電(dian)機轉(zhuan)子(zi)轉(zhuan)不動怎么處理(li)呢？可聯系專業的伺(si)服(fu)(fu)電(dian)機廠家進行維修處理(li)。
