提出了一种用于驱动电梯设备（100）中的悬挂元件（3）的驱动机器（1）。 驱动机（1）包括一个马达中的一个（7）的驱动可移动部件（9），静态部件（10）和用于支撑轴承（27），所述可移动部件（9）相对于所述静止部件（10）。 在这种情况下，轴承（27）中的导电润滑剂被添加用于润滑可移动部件（9）。 通过提供导电润滑油到轴承（27）可以是，在特别是使用产生的可动部件上的电荷，例如可以积累，例如带夹套的带（25），支撑装置（3）时避免，牵引绳轮（23）和 它是由于由于破坏翻转和电镀所导致的高电压。

It is proposed a driving machine (1) for driving a support means (3) in an elevator system (100). The drive machine (1) comprises one of a motor (7) to be driven movable component (9), a static component (10) and a bearing (27) for supporting said movable component (9) relative to the static component (10). In this case, an electrically conductive lubricant in the bearing (27) for lubrication of the moving component (9) is accommodated. By providing an electrically conductive lubricant to the bearing (27) can be avoided that in particular when using a jacketed belt (25) as support means (3) generated electric charges on a movable component such as can accumulate, for example, a traction sheave (23) and occurs due characterized bewirkter high electrical voltages to harmful sparkovers and Elektropitting.
