Hexapods

Positioning platforms for 6 degrees of freedom 

A hexapod system is a device for motion and precise positioning in all three linear and rotational axes. Hexapods use parallel kinematics meaning that all drives act together on the moving platform. Each hexapod system is equipped with a powerful controller transforming each user command into specific motion for each actuator or motor. The software package is user-friendly and all commands are specified in a Cartesian coordinate system, with user-defined pivot point. This feature makes the hexapod especially easy to integrate into end-user systems.

The Hexapods come with various actuators and motors depending on the application demand. An overall high stiffness of the system makes mounting of the hexapod in any direction possible. Joints are an important key factor to stiffness and precision.

Product technologies

Below you can find more information about specific product types. User the tabs to navigate and read more about the different product types.

DC & Stepper Motor

Technical information

  • Travel Range – Up to 100 mm in one dimension
  • Sensor Resolution – From 50 nm
  • Load – Up to 1 Ton as standard
  • Dynamics – Up to 25 Hz operation

More information

A stepper motor divides a full revolution into a number of full steps with equal distance between them. As each step size is known, the stepper motor can operate in open-loop mode without any position sensor. The stepper motor has long lifetime service and is especially suitable for vacuum applications. A DC motor rotates constantly as an operating voltage is applied and the velocity is directly proportional to the input voltage. DC motors with position feedback are called servo motors. These motors have high dynamics with large velocity range, low vibration and offers high torque. Brushless DC motors are increasingly used as they have lower wear and increased power efficiency.

Piezo Motor

Technical information

  • Travel Range – Up to 14 mm
  • Sensor Resolution – from 1 nm
  • Compact Size – 80 mm in width
  • Power Saving – Self-Locking at rest

More information

Piezo inertia drives which are compact and inexpensive piezo based drives with high holding forces up to 10 N and virtually no limitation of the travel range. The self-locking drive holds the position of the stage mechanically stable and optical encoders are used for very high accuracy. Crossed roller bearings offer a stiff and low friction guiding for smooth motion and compact design.

Magnetic Direct Motor/Drive

Technical information

  • Travel Range – Up to 15 mm
  • Sensor Resolution – from 5 nm
  • Volocity – 250 mm/s
  • Power Saving – Self-Locking at rest

More information

Voice coil actuators and magnetic linear drives utilize the fact that the force acting on a current carrying conductor in a magnetic field is proportional to the strength of the magnetic field and the current. This drive offers advantages compared to common spindle-based technologies as it uses few mechanical components, this results in less friction, therefore less wear, backlash and thus more precision as well as much higher dynamics.
