Four new three-axis stages from OES (Optimal Engineering Systems, Inc.) feature four different motor options to best fit application needs.

The YPR-45-15-60 Series of three-axes stages were developed through the integration of a 60 mm diameter rotary stage (upper axis) capable of 360 degrees of continuous operation, and two goniometers (middle and lower axes) each having travel ranges of +/- 15 degrees and +/- 45 respectively.

This series of three-axes stages feature four motor options. The -01 option is stepper motor driven, the -02 option is three-phase servo-motor driven, the -03 is dc servo-motor driven, and the -04 option is stepper-motor driven with quadrature optical encoders for position verification.

The rotary axis of the -01 and -04 versions has a maximum rotational speed of 30 degrees/sec and a resolution of 0.002 degrees when 10 micro-steps per step motor driver is in use. The positional accuracy is 0.05 degrees, and repeatability is +/- 0.01 degrees. The -02 and -03 versions move at the speed up to 45 degrees/sec. This rotary axis has a precision pattern of threaded holes for mounting tooling or fixtures.

The goniometer (middle and lower) axes of the -01 and -04 versions have a maximum speed of 14 degrees/sec. The positional accuracy of each axis is 0.05 degrees, and repeatability is +/- 0.01 degrees. The -02 and -03 servo-motor versions with quadrature incremental optical encoders travel at up to 45 degrees/sec with greater resolution, accuracy, and repeatability.

The rotary axis is equipped with a HOME switch to signal the motion controller to the HOME position. The other two axes are equipped with a positive and negative limit switch to signal the motion controller that end of travel is reached. 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. The stages are suitable for applications including laser scanning, drilling, and machining, reverse engineering, inspection, assembly, measurements, tracking, and positioning, among others.
