OSM-B500-A1 C8451-A70-A31-1 步進電機特點是體積小，壽命長，壽命通常取決于軸承壽命，質量合格的步進電機可達上萬至數萬小時。

  補充：步進電機的使用壽命還與應用環境、供電電壓、負載還有一定關系，比如電腦雕刻機給步進電機的供電電壓較高，電流較大，運行速度高，負載大，因此電腦雕刻機上使用的步進電機使用壽命往往在兩萬個小時以內，除了軸承損耗，還有電機溫度高導致的磁衰減和線圈老化等問題。另外有的步進電機應用環境溫度高，或者有油污、粉塵、水等污染，也會縮短使用壽命。

  延長步進電機使用壽命的方法有：

  1、保持良好的運行環境，注意防水、防塵，在溫度高的環境需要散熱，在溫度過低的環境需要通電預熱。

  2、設置驅動電流時，不要將輸入電流大于步進電機的額定電流。

  3、如果設備沒有特殊要求，請選擇半流鎖定，山社步進電機驅動器會有靜態電流選項或默認靜態半流，減少步進電機發熱。
