Belt Drive Rotation Stage, 360°, DC Servo Motor

The URB100CC rotation stage is based on our popular URS series, but features a belt drive instead of a worm gear. The belt drive offers significantly higher rotation speeds of up to 720°/s without sacrificing life time expectancies. Typical applications are LIDAR, 3D imaging, or film thickness measurements of semiconductor wafers. Common to these applications are fast rotations over larger angles or continuous spinning at very high duty cycles and with high precision requirements with regards to wobble, angular repeatability and speed stability. Like the URS series, the URB100CC features a proprietary 4-contact point ball bearing. The unique, 2-piece design provides exceptional stiffness, high reliability and outstanding wobble and eccentricity. The enhanced low-profile package supplies easy top down mounting options and is mechanically compatible with our ILS series of linear stages (note, motor protrudes the lower surface of the stage). Position feedback is provided by a motor mounted 2000 cts/rev. rotary encoder. To minimize the effects of drive chain hysteresis impacting repeatability, positions should be always approached from the same direction of motion.
