OSM-B500-A1 C8451-A70-A31-1 步进电机特点是体积小，寿命长，寿命通常取决于轴承寿命，质量合格的步进电机可达上万至数万小时。

  补充：步进电机的使用寿命还与应用环境、供电电压、负载还有一定关系，比如电脑雕刻机给步进电机的供电电压较高，电流较大，运行速度高，负载大，因此电脑雕刻机上使用的步进电机使用寿命往往在两万个小时以内，除了轴承损耗，还有电机温度高导致的磁衰减和线圈老化等问题。另外有的步进电机应用环境温度高，或者有油污、粉尘、水等污染，也会缩短使用寿命。

  延长步进电机使用寿命的方法有：

  1、保持良好的运行环境，注意防水、防尘，在温度高的环境需要散热，在温度过低的环境需要通电预热。

  2、设置驱动电流时，不要将输入电流大于步进电机的额定电流。

  3、如果设备没有特殊要求，请选择半流锁定，山社步进电机驱动器会有静态电流选项或默认静态半流，减少步进电机发热。
