High Precision Hexapod
High Precision Hexapod
Aerotech’s HexGen™ Hexapods represent a significant advance in six-degree-of-freedom positioning performance. The HEX500-350HL high-load, precision hexapod is ideal for applications in x-ray diffraction, sensor testing, and high-force device manipulation. With its high-load capacity, large travels, high speeds, and sub-micrometer precision, the HEX500-350HL means no compromising on application specifications. The HEX500-350HL is the only hexapod on the market today that provides guaranteed positioning accuracy specifications. The HEX500-350HL is actuated with six high-accuracy struts that are built with precision preloaded bearings, ball screws, and drive components. Unlike competitive hexapods driven by DC brushed servomotors, the HEX500-350HL is driven by AC brushless, slotless servomotors that maximize device lifetime and performance. The servomotors are directly coupled to the actuator ball-screw enabling increased drive stiffness, higher positioning accuracy, and better minimum incremental motion (20 nm in XYZ and 0.2 ?rad for ?x?y?z) when compared to competitive designs that use belts or compliant couplings. The strut pivot-joints are engineered to provide low friction and high stiffness enhancing overall hexapod performance.
