April 7, 2015 - Physik Instrumente released the H-860KMAG 6-axis hexapod for high dynamics motion and vibration simulations that require extremely smooth, and quiet high-speed motion.
The hexapod is driven by non-contact PIMag voice-coil linear motors and guided by frictionless flexures. The absence of conventional bearings based on rolling elements reduces noise, and provides basically unlimited service life because the zero-wear flexures and motors require neither maintenance nor lubricants. Lightweight struts in combination with stiff, zero-play flexure joints provide very fast response with 4g acceleration, operating frequencies up to 100 Hz (small signal), and velocity to 250mm/sec. The hexapods have been tested to meet the CIPA certification standard for simulating camera shake when taking photographs.
The 6-axis hexapod motion system is based on a parallel kinematic actuator structure for six degrees of freedom. The used-defined pivot point (center of rotation) can be changed on the fly by one software command for increased versatility. Tracking of pre-defined trajectories, sinusoidal curves, and freely definable paths with high trajectory accuracy can easily be programmed with the included software tools.
Extremely stiff carbon fiber components reduce the inertia and result in a high Eigenfrequency of 200Hz, important for fast response, high operating frequencies, and high throughput motion. The direct-drive hexapod comes with a powerful digital vector motion controller with open software architecture and hexapod-specific software.
Applications include motion simulation, image stabilization test equipment, vibration simulation, precision positioning and alignment of opto-mechanical components.
