Product Description:
The R2AA06040HXP00 is a medium-inertia servo motor manufactured by Sanyo Denki within the R SANMOTION Servo Motors series. Designed for industrial automation stages that require accurate and stable motion, this 60 mm flange unit converts drive commands into torque for indexing tables, pick-and-place heads, and small conveyors. Its compact frame dimensions support installation where mounting space is limited. The 200 V class winding is intended for use with a compatible SANMOTION R servo drive.
At its nominal operating point, the motor delivers 400 W of mechanical output and produces a continuous shaft torque of 1.27 N·m. It operates from 200 V three-phase power and draws a phase current of 1.7 Arms. The electromagnetic design provides a torque constant of 0.816 N·m/Arms, allowing the amplifier current to produce a predictable amount of torque. A continuous stall torque of 1.37 N·m allows the powered motor to hold static loads within its operating limits. The 60 mm flange provides a compact mounting interface for small automation axes, while the medium-inertia rotor supports steady speed regulation under changing loads.
For rapid acceleration, the motor can produce a peak torque of 4.8 N·m while remaining within its peak winding current of 7.1 Arms. The phase resistance is 3.3 Ω, and the back electromotive force constant is 28.5 mV per min⁻¹ of rotational speed. Position feedback comes from a battery-backed absolute encoder that tracks up to 65,536 revolutions and provides 131,072 divisions per revolution for precise position measurement. The absolute feedback system retains multi-turn position information when the main machine power is removed, provided that the encoder battery remains connected and sufficiently charged. The motor does not include a holding brake, so an external mechanical clamp is required when a load must remain locked after motor power is removed. During powered operation, the servo drive can use encoder feedback to regulate position, speed, and torque throughout repeated motion cycles.
