The Dover RTR™ series stages are available in 4-, 6-, 8-, 10-, and 12-inch diameter rotary stage versions that include a preloaded, anti-backlash drive assembly to provide exceptional angular accuracy and repeatability. There is a standard internally mounted Hall effect reference sensor that is wired directly to a screw locking connector for homing position registration accurate to a single step. A stepper motor with a manual knob and a flexible coupling are included with this motorized rotary stage. A second sensor can also be installed to electrically restrict rotary table travel in applications where the full rotational travel needs to be limited to a specific angle of travel less than 360 degrees.
Clear apertures (or through hole) are optionally available in different diameters. Our integral rotary motor encoder can be specified with our RTR™ series rotary stage, where it provides 0.001-degree resolution encoder feedback when combined with a 180:1 worm gear ratio, 200 step-per-revolution stepper motor, and a divide-by-ten micro-step drive. For increased rotary motion resolution, 400-count stepper motor or rotary servo motor are available.
