H-840 6-Axis Hexapod

The H-840 hexapod series is the universal choice for tasks that demand precision positioning in multiple degrees of freedom. Variants range for those optimized for high dynamics, for example applications like motion simulators, or designs with advanced gearhead support for providing higher load capability.

The parallel-kinematic design for six degrees of freedom is significantly more compact and stiff than comparable serial-kinematic i.e., stacked, systems. Other advantages are that they provide improved motion tracking and repeatability. In addition, the moved mass is lower, enabling better dynamic performance, which is the same for all motion axes. Moreover, cable management is no longer an issue, because cables are not moved.

Use of brushless DC motor (BLDC)

Brushless DC motors are particularly suitable for high rotational speeds. They can be controlled very accurately and ensure high precision. Because they dispense with mechanical electrical contacts, they run smoothly, are wear-free and achieve a long lifetime.

Use of absolute encoder

Absolute encoders supply explicit position information that enables immediate determination of the position. This means that referencing is not required during switch-on, which increases efficiency and safety during operation.

PI hexapod simulation tool

The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before making a purchase, you can check whether a particular hexapod model can handle the loads, forces, and torques occurring in an application. For this purpose, the simulation tool takes into account the position and motion of the hexapod as well as the pivot point and several reference coordinate systems.

Fields of application

Research and industry. For motion simulation (CIPA certified), tool inspection, life science, micromanufacturing. Micro-manipulation of parts, industrial alignment systems.
