Physik Instrumente introduces H-845 hexapods

May 18, 2015 - Physik Instrumente introduces H-845 hexapods that can move loads weighing up to one metric ton.

The H-845 series provides an easy solution to complex multi-axis precision motion applications with models available in various travel ranges, load capacities, and velocities. With 6 degrees of freedom, no moving cables and a large clear aperture – advantages of the parallel-kinematic design. – the new H-845 models benefit from PI’s long experience with hexapod design,

H-845 hexapods achieve step sizes from 0.5µm and repeatability to 2µm, with linear travel ranges to 340mm and rotation ranges to 60 degrees. Each hexapod comes with the C-887 high performance vector motion controller, powering the six hexapod axes and 2 additional motorized single axes. Control is easy - all position values can be commanded simply as Cartesian coordinates, and, the center of rotation can be changed on the fly with a software command.

Features & Advantages

  • 6 Axis Motion with virtual pivot point (XYZ, Pitch, Roll, Yaw)
  • Handles loads to 1 metric ton
  • Actuator resolution <50 nanometers
  • Velocity to 20 mm/sec
  • Repeatability to ±2 microns
  • Positioning range up to 220mm (linear) 60 deg (rotations)
  • Scalable design: Dimensions, travel ranges and loads
  • Drive: brushless motors with brake
  • Includes State-of-the Art Vector Motion Controller
  • Extensive software package
