Rotary positioning stage ARMS-150 series

motorized1-axisdirect-drive

Design Features •Designed for highly accurate motion generation •Velocity stability of 0.0001% over 360 degrees •Position resolution to 0.02 arc sec •Payloads to 230 kg •Integrated slip rings and optional rotary unions •Direct-drive brushless motor options for high speed or high torque Accurate Velocity and Positioning The ARMS family of stages provides excellent velocity and positioning control. When coupled with Aerotech's advanced controls, resolution can be as fine as 0.02 arc second, with accuracy to ±2.5 arc second and repeatability to ±0.5 arc second. The motor and high-performance rotary encoder are directly coupled to a common shaft. The absence of gear trains and mechanical couplings means no position errors caused by hysteresis, windup, or backlash. The ARMS has rate resolution down to 0.001 deg/s and rate stability to 0.0001%. Aerotech’s ARMS series direct-drive rotary motion simulators provide superior angular rates, accelerations and positioning for the testing of inertial components and systems such as MEMS, gyroscopes, inertial measurement units, avionics and accelerometers. ARMS stages are configuragle with slip rings and rotary unions.
