Performance and Applications of Inertia Based Positioning Drives: Q-Motion

Size matters in miniaturization and automation – smaller is usually better. Traditional electromagnetic motors have limitations when it comes to shrinking dimensions while maintaining high efficiency and accuracy of motion with minimized energy consumption. Piezo ceramic inertia motors can fill this gap. The Q-Motion dubbed miniature direct drives can be employed in linear positioners, rotary […]

Performance of a Large Motorized Rotary Air Bearing Stage for Synchrotron Crystallography

PI recently built a large 300mm diameter rotary air bearing stage for use in a synchrotron beamline test facility. The beamline, when finished, will be used for Macromolecular Crystallography. This stage was designed with the goal of achieving best-possible performance for the following specifications: Stiffness Load capacity Radial runout error motion Velocity smoothness The application […]
