SF79R39減速機電機安裝注意事項:

注意要將設備擺放平穩,固定好地腳和法蘭,并精確校準直接連接的聯軸器。防止安裝不當造成旋轉頻率和雙倍電源頻率的諧振。用手轉動轉子,檢查有無異常摩擦聲。在未聯接外部設備的狀態下檢查轉向。齒輪減速電機

SF79R39減速機電機安裝在塵埃灰屑或水滴等較多處,會對本機器會產生不良影響時,請用覆蓋物蓋住,覆蓋物不要密封,必須留有通氣口(若工作環境粉塵密聚或需要防水機種,購買時請特別說明)。

嚴禁在SF79R39減速機電機的周圍放置可燃物。否則有可能會導致火災。

嚴禁在SF79R39減速機電機的周圍放置阻礙通風的障礙物。否則,可能會因冷卻不暢、異常過熱而導致燙傷、火災等情況。

嚴禁站立在SF79R39減速機電機上面或懸掛其上。否則有可能會導致受傷。

請勿赤手觸摸SF79R39減速機電機的軸端部、內徑部的鍵槽。否則有可能會導致受傷。自鎖減速機

安裝完后,檢查電機是否通風良好。且確認沒有鄰近設備、表面或直射陽光向電機額外輻射熱量。

SF79R39減速機電機電流異常解決方案:

SF79R39減速機電機外殼帶電:電源線碰機殼,且絕緣皮破損,電源線修復;繞組受潮、絕緣老化、接地裝置壞,維修換定子線圈,重裝接地線。

SF79R39減速機電機三相電流不平衡:三相電壓不平衡,維修電源電壓;線圈部分線圈短路,更換定子線圈;線圈內有一個線苞嵌反,更換定子線圈。

SF79R39減速機電機電流過大:電源電壓偏差大,維修電源電壓;接法錯誤,應是Y接法錯用為△接法,接法更正;更換電機,定轉子擦;負載過大,選用大容量電機或減小負載。伺服電機蝸輪蝸桿減速機
