Three-axis stages with four motor options for demanding motion control applications introduced by OES
VAN NUYS, Calif. – Optimal Engineering Systems Inc. (OES) in Van Nuys, Calif., is introducing the YPR-45-45-100 series of pitch, roll, and yaw three-axis stages for demanding motion control applications.
These three-axis stages are the integration of two +/- 45 degrees goniometers for low (pitch) and middle (roll) axes, and aupper, 100-millimeter diameter, rotary stage (yaw axis).
The integration of goniometers and rotary stage identifies crystals to estimate hyperspectral bidirectional reflectance, measurements of radiation patterns of LEDs, manufacturing of quartz oscillator plates using quartz cutting X-rays, examining cutting edges of medical instruments, gloss measurements, laser machining and drilling, aligning mirrors, tracking and scanning.
Four motor options
These stages feature four motor options. The -01 option is stepper motor driven; the -02 option is three-phase brushless servo motor driven with quadrature optical encoders; the -03 is brushed DC servo motor driven with quadrature optical encoders; and the -04 option is stepper motor driven with quadrature optical encoders for position verification.
The stepper motors have a resolution of 0.002 degrees, positional accuracy of 0.05 degrees, and repeatability is +/-0.01 degrees with a 10 micro-steps per step motor driver.
The goniometer (middle and lower) axes of the -01 and -04 versions have a maximum speed of 14 degrees per second. The positional accuracy of each axis is 0.05 degrees, and repeatability is +/-0.01 degrees.
The -02 and -03 servo motor options with quadrature incremental optical encoders travel at speeds up to 45 degrees per second and have greater resolution, positional accuracy, and repeatability.
The rotary axis is equipped with an INDEX switch to signal the motion controller the HOME position. The goniometer axes are equipped with a positive and negative limit switches to signal the motion controller when end of travel is reached. The rotary axis has a precision pattern of threaded holes for mounting tooling or fixtures and all axes have calibrated scales for visual inspection.
Each of these stages can be ordered with a fully plug-and-play compatible multi-axis motion controller for any motor combination from OES. For more information contact OES online at www.oesincorp.com.
