H-845 High-Load Hexapod

Positioning 1 Ton with Micrometer Precision

PI H-845
    • Load capacity to 1000 kg
    • Velocity to 20 mm/s
    • Repeatability to ±2 µm
    • Travel ranges to 220 mm / 60°
    • Scalable design: Dimensions, travel ranges and loads
    • Actuator resolution to 40 nm
    • Drive: brushless motors with brake
    • Sophisticated controller using vector algorithms, virtual pivot point
    • Extensive software support

Reference-class 6-axis positioning system

Parallel-kinematic design for six degrees of freedom making it significantly more compact and stiff than serial-kinematic systems, higher dynamic range, no moved cables: Higher reliability, reduced friction. Large clear aperture
Brushless DC motors with brakes

Basis for rapid implementation of customer requests

The high-load Hexapod has a modular structure and uses a set of different modules for motor, drive unit and joint. The platforms can be adapted to the customer's application. This allows for rapid implementation and resource-saving integration of special customer requirements

Powerful digital controller, open software architecture

6D vector motion controller for Hexapods, incl. two additional servo axes. Arbitrary, stable pivot point, software-selectable. Positions commanded in Cartesian coordinates. Macro command language. Open-source LabVIEW driver and libraries. Determination of the workspace. Virtual machine for Hexapod emulation. Optional: Software for avoiding collisions in restricted workspace

Fields of application 

Research and industry. For astronomy, aviation and aerospace

* The travel ranges of the individual coordinates (X, Y, Z, θX, θY, θZ) are interdependent. The data for each axis in this table shows its maximum travel, where all other axes are at their zero positions. If the other linear or rotational coordinates are not zero, the available travel may be less.
