    • An elevator machine assembly includes a motor (22), a brake (26) and a traction sheave. A coupling (40) couples one of the motor to the traction sheave such that the traction sheave rotates responsive to movement of the motor or couples the brake to the traction sheave such that the brake selectively limits movement of the traction sheave. The coupling provides an output that is indicative of torque at the traction sheave. In a disclosed example, the coupling comprises a magnetoelastic material that provides a magnetic field that is indicative of torque at the traction sheave. An exemplary method of operating a motor for selectively moving an elevator traction sheave includes determining a torque at the traction sheave. A command signal for controlling the motor is generated based upon the determined torque.
    • 电梯机组件包括电机(22),制动器(26)和牵引滑轮。 联接器(40)将马达中的一个连接到牵引滑轮,使得牵引滑轮响应于马达的运动而旋转或将制动器耦合到牵引滑轮,使得制动器选择性地限制牵引滑轮的运动。 联轴器提供指示牵引滑轮​​处的扭矩的输出。 在公开的示例中,耦合包括磁弹性材料,其提供指示牵引滑轮​​处的扭矩的磁场。 操作电动机以选择性地移动电梯牵引滑轮的示例性方法包括确定牵引滑轮处的扭矩。 基于确定的转矩来生成用于控制电动机的指令信号。
