The URS100BPP Rotation Stage provides precision 360° continuous motion in a low profile package. It meet the requirements of numerous research and industrial applications and are directly compatible with our XM, GTS, ILS, IMS and other series of 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 ESP301, low noise operation and very small incremental motions are guaranteed. The stepper motor versions do 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, eliminating the need for a gear or belt drive. 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 was improved to guarantee a backlash-free operation with an MTBF of 20,000 hours.


URS100BPP旋转阶段提供精密360°连续动作在低调包中。它满足众多研究和工业应用的要求，并与我们的XM、GTS、ILS、IMS等系列线性级直接兼容。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ESP301等具有较高微步能力的运动控制器一起使用时，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，无需齿轮或皮带传动。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。这使得URS阶段能够更好地支持更高或偏心负载。同时对蜗轮柔性预压系统进行了改进，保证了蜗轮在2万小时无故障运行。
