    • An elevator system having a regenerative elevator drive and an electrical or mechanical energy storage system includes an energy management controller. Voltage and state-of-charge of the energy storage system are monitored by the energy management controller. During sustained marginal quality power conditions of the primary input power to the elevator, the energy management controller maintains and extends operation of the elevator system by selecting a mode of operation where the motor of the elevator is powered by the energy storage system, while using power available from the grid and the elevator regenerative runs for charging the energy storage system. The energy management controller may delay elevator runs, reduce elevator speeds, temporarily shut down elevator operation, and adjust operating limits of the energy storage system based upon line voltage, state-of-charge, elevator loading, and power requirements of the elevator system.
    • 具有再生电梯驱动器和电或机械能量存储系统的电梯系统包括能量管理控制器。 能量存储系统的电压和充电状态由能量管理控制器监视。 在对电梯的主要输入功率的持续的边缘质量功率条件期间,能量管理控制器通过选择一种操作模式来维护和扩展电梯系统的操作,其中电梯的电动机由能量存储系统供电,同时使用电力 可从电网获得,并且电梯再生运行用于为能量存储系统充电。 能量管理控制器可以延迟电梯运行,降低电梯速度,暂时关闭电梯运行,并且基于电梯电压,电荷负载,电梯负载和电梯系统的功率要求来调节能量存储系统的运行极限。

    • A drive belt (30) includes a body portion having at least a drive surface (32) adapted to engage a member (23) to be driven by the drive belt (30). At least a portion of at least one lateral surface (42) includes a protective layer (50). In a disclosed example, the body of the belt (30) is formed using a first polymer material and the protective layer (50) is formed using a second, different polymer material. The protective layer (50) can have different wear characteristics to resist abrasion, for example, and a different hardness or friction characteristic than the material selected to form the body of the belt including the drive surface (32).
    • 驱动带(30)包括主体部分,该主体部分具有至少一个驱动表面(32),该驱动表面适于接合由传动带(30)驱动的构件(23)。 至少一个侧表面(42)的至少一部分包括保护层(50)。 在公开的示例中,带(30)的主体使用第一聚合物材料形成,并且使用第二种不同的聚合物材料形成保护层(50)。 保护层(50)可以具有不同于耐磨性的磨损特性,例如具有与选择以形成包括驱动表面(32)的皮带主体的材料不同的硬度或摩擦特性。
