Aerotech’s new ARMS series rotary motion simulators provide highly accurate angular rates, acceleration and position profiles for inertial component test systems and instruments. The new simulators include a choice of slip ring assemblies and rotating unions for interfacing with the Unit Under Test (UUT) and are supplied with matched servo drives, motion controls and GUI motion industrial design software. Users are able to generate or download complex rotary motion profiles and execute them with a velocity stability to 0.0001% over 360 degrees for direct loads up to 170 kg. The range is aimed at dynamic in-process testing of gyroscopes, MEMS detection, accelerometers and other rate table applications requiring ultra-precise rotational profiling for use on avionics equipment, automobiles, and other ground based vehicles and inertial platforms.
ARMS motion simulators are available in three basic models with nominal width and tabletop diameter of 146 mm, 196 mm and 260 mm. Each model includes a choice of two stack heights to accommodate Aerotech’s high-torque S-series ironless and slotless direct-drive servomotors with peak torque from 11.7 Nm to 146 Nm. With no motor cogging, absolutely no torque ripple and zero backlash, the S-series allows smooth and precise speed control and peak acceleration in excess of 20,000 degrees per second.
