    • A mover assembly (16) that moves or positions an object (12) along a first axis includes a motor (20) and a coupling assembly (22). The motor (20) includes a motor output (332) that is moved along the first axis and about the first axis. The coupling assembly (22) includes a stage (344) that couples the motor output (332) to the object (12) and a stage guide (346) that guides the motion of the stage (344) along the first axis. In one embodiment, the stage guide (346) is a linear bearing that allows for motion of the stage (344) along the first axis and inhibits motion of the stage (344) about the first axis, along a second axis and along a third axis. Additionally, the coupling assembly (22) can include a measurement system (28) that monitors the movement of the stage (344).
    • 沿着第一轴移动或定位物体(12)的动子组件(16)包括马达(20)和联接组件(22)。 马达(20)包括沿第一轴线和第一轴线移动的马达输出(332)。 联接组件(22)包括将马达输出(332)耦合到物体(12)的台(344)和引导台(344)沿着第一轴的运动的平台引导件(346)。 在一个实施例中,平台引导件(346)是线性轴承,其允许平台(344)沿着第一轴线的运动并且沿着第二轴线并沿着第三轴线阻止台架(344)围绕第一轴线的运动 轴。 另外,联接组件(22)可以包括监测台(344)的运动的测量系统(28)。
