一、步進電機的使用壽命有多久

步進電機特點(dian)是(shi)體積小，壽(shou)命(ming)(ming)長，步進電機(ji)的使(shi)用壽(shou)命(ming)(ming)通常取決于軸(zhou)承壽(shou)命(ming)(ming)，質量合格(ge)的步進電機(ji)可(ke)達上萬(wan)至數萬(wan)小時。

步進(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的使(shi)用壽命(ming)(ming)還與應用環(huan)(huan)境、供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、負載還有(you)一(yi)定關(guan)系，比如電(dian)(dian)(dian)(dian)(dian)(dian)腦雕刻(ke)機(ji)(ji)給步進(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)較高，電(dian)(dian)(dian)(dian)(dian)(dian)流較大，運行(xing)速度(du)高，負載大，因此電(dian)(dian)(dian)(dian)(dian)(dian)腦雕刻(ke)機(ji)(ji)上使(shi)用的步進(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)使(shi)用壽命(ming)(ming)往往在兩萬個(ge)小時(shi)以內，除了軸承(cheng)損耗，還有(you)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)溫(wen)度(du)高導致的磁衰減和線圈老化等問(wen)題。另外有(you)的步進(jin)(jin)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)應用環(huan)(huan)境溫(wen)度(du)高，或者有(you)油污、粉(fen)塵(chen)、水(shui)等污染，也會(hui)縮短使(shi)用壽命(ming)(ming)。

二、步進電機怎么保養

1、步進電機應存放、安裝(zhuang)在環境(jing)溫度(du)為-40～+50℃、相對濕度(du)不大于95％的清潔(jie)通風良好的環境(jing)內，空氣中不得含(han)有腐(fu)蝕性、易(yi)燃性氣體、油霧(wu)、粉塵。步進電機在(zai)搬運過程中應小心輕(qing)放，避免碰(peng)撞(zhuang)和沖(chong)擊，嚴禁與酸堿等腐蝕(shi)性(xing)物質(zhi)放在(zai)一起。

2、步(bu)進(jin)電機的安裝環(huan)境(jing)(jing)要求(qiu)(qiu)同存(cun)放環(huan)境(jing)(jing)要求(qiu)(qiu)，另外步(bu)進(jin)電機長(chang)時間接觸滲透(tou)力(li)很強的液(ye)態(tai)物質(zhi)，會導致運行異常或壽命縮短。應盡量(liang)避免(mian)接觸，更不能將其浸泡在液(ye)態(tai)物質(zhi)里。

3、步進電(dian)機運行(xing)時(shi)，要(yao)防止人體及外來物質觸及步進電(dian)機內(nei)部的(de)(de)電(dian)氣、機械的(de)(de)危險性部件，保證人的(de)(de)安全和步進電(dian)機的(de)(de)正常工(gong)作。

4、當步進(jin)電(dian)機(ji)(ji)(ji)(ji)使用一段時間后，表面會有(you)一些灰(hui)(hui)塵(chen)(chen)(chen)存在，灰(hui)(hui)塵(chen)(chen)(chen)太多會影響電(dian)機(ji)(ji)(ji)(ji)的(de)美(mei)觀(guan)性和電(dian)機(ji)(ji)(ji)(ji)的(de)散熱。因此要及時清(qing)除(chu)灰(hui)(hui)塵(chen)(chen)(chen)，保證步進(jin)電(dian)機(ji)(ji)(ji)(ji)恢復到干凈、美(mei)觀(guan)的(de)狀(zhuang)態。步進(jin)電(dian)機(ji)(ji)(ji)(ji)在做(zuo)清(qing)潔時，要關閉(bi)設備電(dian)源，不能(neng)用腐蝕性的(de)有(you)機(ji)(ji)(ji)(ji)溶(rong)劑清(qing)潔。

5、如果步進電機在運(yun)(yun)行(xing)中，出現各種異(yi)(yi)響，那么需要立刻停機檢查，檢查內(nei)容包括但不限(xian)于：聯(lian)軸器是否松動(dong)，皮帶輪(lun)是否松動(dong)，各個緊固螺絲是否松動(dong)，滑塊、滑軌是否異(yi)(yi)常(chang)、各定位感(gan)應器是異(yi)(yi)常(chang)、線路(lu)連接(jie)是否有異(yi)(yi)常(chang)等。若發(fa)現異(yi)(yi)常(chang)，應及(ji)時處(chu)理，等處(chu)理好后再恢復(fu)設備正常(chang)運(yun)(yun)行(xing)。

6、步進電機在運行的時候，要檢查溫度是否合適，一般手觸步進電機外殼不會(hui)感(gan)到十(shi)分(fen)燙手即(ji)可。如(ru)機體(ti)溫度(du)超過130°，步進(jin)電機會(hui)損壞，應(ying)及時檢查、處理。

7、設(she)置驅動電(dian)(dian)(dian)流時，請勿(wu)使輸(shu)入電(dian)(dian)(dian)流大于(yu)步進(jin)電(dian)(dian)(dian)機的額(e)定電(dian)(dian)(dian)流。

8、如果設備沒有特殊要求(qiu)，請(qing)選擇半(ban)電流(liu)鎖定。有的步進(jin)電機驅動(dong)器有靜態電流(liu)選項(xiang)或默認的靜態半(ban)電流(liu)，以減少步進(jin)電機的發(fa)熱。
