1. 轴承寿命
根据ISO 281，轴承的正常寿命L10h 定义为在特定条件下90% 的相同轴承在一系列测试中所达到或超过的运行小时数。50% 的轴承至少达到这一数字的五倍。
2.润滑
电机交货时，已经使用优质的润滑脂对电机进行润滑。机座号71-250电机采用润滑轴承。机座号280-355电机采用再润滑轴承。轴承使用寿命指导值2-8 极电机约为40,000 小时 。
3.允许轴向力
表中提供了环境温度为25℃时，50Hz 的正常条件下，径向力为零时的轴伸允许轴向力（N）。分别对轴承寿命满足20000 和40000 小时进行计算。
4. 轴承电流
功率大于等于100kW 的电机应该采用消除轴承电流和电压的防护措施，使用镀陶轴（变量代码692）或绝缘轴承（变量代码701）。
