Performance Unique to the Market
Many trade-offs exist in the design and specification of a motion system. With its high speeds and sub-micrometer precision, the HEX300-230HL eliminates compromises on application specifications. Aerotech’s HexGen hexapods are the only hexapods on the market today that provide guaranteed positioning accuracy specifications below 5 µm.
Superior Structural Design
The HEX300-230HL is actuated with six high-accuracy struts built with precision preloaded bearings, ball screws, and drive components. Unlike competitive hexapods driven by DC brushed servomotors, the HEX300-230HL is driven by Aerotech’s AC brushless, slotless servomotors that maximize device lifetime and performance. Directly coupling the AC brushless servomotors to the ball screw enables increased drive stiffness, higher positioning accuracy, and better minimum incremental motion (20 nm in XYZ and 0.2 µrad for θxθyθz) when compared to competitive designs using belts, gearheads, or compliant couplings. Specially engineered strut pivot-joints provide low friction and high stiffness enhancing the overall hexapod performance.
Design Flexibility
The HEX300-230HL’s design optimizes flexibility and customization options for the user. The platform and base can be easily modified with user-specific features or mounting patterns. The HEX300-230HL features a 100 mm diameter clear aperture in the platform while a 60 mm diameter clear aperture in the base allows workpiece access from the bottom. The base mounting holes adapt directly to English or metric optical tables.
Vacuum Options Available
Aerotech hexapods can be vacuum prepared for demanding applications such as synchrotron sample or optics manipulation, semiconductor manufacturing and inspection, or satellite sensor testing.
Powerful Controls and Software
Driving the HEX300-230HL is Aerotech’s Automation1 Software-Based Machine Controller. Built on years of experience in difficult kinematics applications, the Automation1 controller allows simple programming and control of the hexapod in multiple user-defined coordinate systems with an intuitive interface and real-time motion visualization. Aerotech’s free HexGen™ sizing software provides the ability to easily simulate the available travel and workspace of the hexapod.
