High-dynamics motion hexapod microrobot, voice coil drives, 1 kg load capacity, 250 mm/s max. velocity, flexures, high-performance power adapter, 3 m cable set
H-860 6-Axis Motion Hexapod
Magnetic Direct Drive for High Velocity
- High velocity and dynamics
- Minimal moved mass and inertia
- Velocity up to 250 mm/s
- Precise path tracking
- Friction-free voice coil drive
Thanks to its excellent dynamic properties, the H-860 is ideally suited for motion simulation.
It is used in test systems, e.g., for image stabilization in cameras and mobile devices. Further fields of application include quality assurance of camera test systems and image stabilization software; vibration simulation, eye tracking, simulation of human and artificial motion.
The friction-free drive design is based on voice coils drives and flexure guides. The struts and platform are made of carbon fiber for minimal moved mass and inertia.
Parallel-kinematic 6-axis system
Parallel-kinematic design for six degrees of freedom, making it significantly more compact and stiffer than serial-kinematic systems, no moved cables.
Precise running of predefined motion profiles with high path accuracy: Sine curves and freely definable trajectories.
PIMag® voice coil
Voice coil drives consist of two essential components: A permanent magnet and a coil that are located in the air gap of the magnetic field. Thanks to their low weight and friction-free drive principle, voice coil drives are particularly suitable for applications that require high dynamics and high velocities at limited travel ranges. High scan frequencies and precision positioning are also possible with these drives, because they are free of the effects of hysteresis.
PIVirtualMove
The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before purchasing, 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 the position and motion of the hexapod as well as the pivot point and several reference coordinate systems into account.

Bei der Vermessung der Positionsspezifikationen wird die typische Geschwindigkeit verwendet. Die Daten werden als Messprotokoll mit dem Produkt ausgeliefert und bei PI vorgehalten.
Die maximalen Stellwege der einzelnen Koordinaten (X, Y, Z, θX, θY, θZ) sind voneinander abhängig. Die Daten für jede Achse zeigen jeweils ihren maximalen Stellweg, wenn alle anderen Achsen auf der Nullposition des Nominalstellweges stehen und das werkseitige Koordinatensystem verwendet wird, beziehungsweise wenn der Pivotpunkt auf 0,0,0 gesetzt ist.
Technische Daten werden bei PI bei 22 ±3 °C spezifiziert. Die angegebenen Werte gelten im unbelasteten Zustand, wenn nicht anders angegeben. Teilweise sind Eigenschaften voneinander abhängig. Die Angabe "typ." kennzeichnet einen statistischen Mittelwert für eine Eigenschaft; sie gibt keinen garantierten Wert für jedes ausgelieferte Produkt an. Bei der Ausgangsprüfung eines Produkts werden nicht alle, sondern nur ausgewählte Eigenschaften geprüft. Beachten Sie, dass sich einige Produkteigenschaften mit zunehmender Betriebsdauer verschlechtern können.

Technology
Hexapod as Motion Simulator
Motion simulators have higher motion dynamics requirements (shakers).
Multi-Axis Positioners
Hexapod platforms are used for precision positioning and alignment of loads in all six degrees of freedom, three linear axes, and three rotational axes.
Magnetic Direct Drives
In particular in terms of wear and dynamics, magnetic direct drives offer advantages compared to common spindle-based technologies.
