The URS75BPPV6 Vacuum Compatible Rotation Stage provides precision 360° continuous motion in a low profile package. It meets the requirements of numerous research and industrial applications and are directly compatible with our VP, XM, and GTS, linear stages. This stepper motor version is a more economical for less demanding applications. When used with motion controllers with high micro-step capability, like the XPS or ESP300, low noise operation and very small incremental motions are guaranteed. The stepper motor version does not use encoder feedback, but reach a position by the number of commanded steps and micro-steps. For this purpose, the stepper motor is directly attached to the worm screw using a proprietary bellows coupling that has a high torsional stiffness. The high output torque of the stepper motor minimizes the risk of lost steps and provides good linearity between commanded micro-steps and the actual motion of the stage. All URS rotation stages feature a proprietary 4-point contact ball bearing. The unique, 2-piece design of the URS provides a low-profile compact stage with exceptional stiffness, high reliability and outstanding wobble and eccentricity. The tilted worm screw arrangement allows for 4 symmetric mounting holes as compared to other designs that only feature 2 or 3 mounting holes. This enables the URS stages to provide better support of higher or off-centered loads. Additionally, the flexible preloading system for the worm gear guarantees a backlash-free operation with an MTBF of 20,000 hours.

URS75BPPV6真空兼容阶段提供精密360°旋转连续动作在低调包中。它满足众多研究和工业应用的要求，并直接与我们的VP、XM和GTS线性阶段兼容。这个步进电机版本是一个更经济的要求较少的应用程序。与XPS或ESP300等具有较高微步能力的运动控制器配合使用时，保证了低噪声运行和非常小的增量运动。步进电机版本不使用编码器反馈，而是通过指令步长和微步长到达一个位置。为此目的，步进电机直接与蜗杆相连，采用专有的波纹管联轴器，具有较高的扭转刚度。步进电机的输出转矩大，最大限度地降低了步距丢失的风险，并提供了良好的线性之间的命令微步和实际运动的阶段。所有URS旋转阶段均采用专有的4点接触滚珠轴承。独特的，2件式的URS设计提供了一个低轮廓紧凑的阶段，具有卓越的刚度，高可靠性和突出的摆动和偏心。与其他只有2或3个安装孔的设计相比，倾斜蜗杆结构允许4个对称安装孔。这使URS阶段更好地支持较高或偏心载荷。另外，蜗轮蜗杆的柔性预压系统保证了在20,000小时的MTBF下无返料运行。

可以订购与真空兼容的25pin SubD连接器。
