Three new high accuracy Yaw-Pitch-Roll stages have been introduced by OES (Optimal Engineering Systems, Inc.), the YPR100-10-15-01 (stepper motor driven - pictured), the YPR100-10-15-02 (brushless servo motor driven) and the YPR100-10-15-03 (DC servo motor driven). These Yaw-Pitch-Roll stages are ideal for the precise measurement of compound angles or the curvature of an object.
The Yaw axis (bottom stage) is capable of rotation of large angles and features a 180:1 ratio gear. The positional accuracy is 0.05 degrees and repeatability is +/- 0.01 degrees.
The Pitch axis (middle stage) has cross roller guides and a range of travel of +/- 10 degrees and has an accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees.
The Roll axis (top stage) has cross roller guides and a range of travel of +/- 15 degrees and the 65 mm x 65 mm table has a precise pattern of threaded holes for fixtures or tooling. This stage has an accuracy of 0.05 degrees and repeatability of +/- 0.01 degrees and the total center deflection for all axes is 0.03 mm. The rotation center height is 50 mm.
The Pitch and Roll axes are equipped with end of travel limit switches. The yaw axis has a HOME signal for initialization. Additionally all axes have a calibrated indicator to display the angle of rotation. The maximum speed with stepper motors is 14 degrees/second and 90 degrees/second with servo motors.
The knobs of stepper motors can be replaced with optional optical encoders for position verification. The YPR100-10-15-02 and YP110-10-03 feature servo motors and optical quadrature encoders for very precise closed loop operation and greater speeds. The YPR100-10-15 stages can be ordered plug-and-play with a fully a compatible multi-axis motion controller from OES.
