Three-axis Yaw, Pitch and Roll Stage

Home > Motorized Yaw, Pitch and Roll Stages

The YPR-100-10-15-01 (stepper motor driven), the YPR-100-10-15-02 (brushless servo motor driven with quadrature optical encoder) and the YPR-100-10-15-03 (DC servo motor driven with quadrature optical encoder. 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 typical position 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 YPR-100-10-15-02 and YP110-10-03 feature servo motors and optical quadrature encoders for very precise closed loop operation and greater speeds.

The YPR-100-10-15 Motorized Three-axis Stages require a Motion Controller that can be ordered as a complete plug-and-play system with joystick, trackball, and keypad.
