Internal Product Review
The R2AA08075FXH11M is a well-balanced servo motor with 750 W rated output and a middle inertia design for stable motion control. Absolute encoder feedback at 131072 div/rev supports precise positioning, and 6000 min⁻¹ maximum rotation speed gives the motor strong responsiveness in dynamic applications. An impressive 8.5 N·m peak torque stands out as a key performance advantage.

Product Description:
The R2AA08075FXH11M is a medium-inertia AC servo motor produced by Sanyo Denki within the R SANMOTION Servo Motors series. It uses an absolute encoder configured for incremental systems to feed position data back to the drive and mounts to machinery through an 80 mm square flange. No holding brake is fitted, so external mechanisms must secure vertical loads when power is off. Compliance with CE and UL requirements permits installation in regions that apply those standards. In automated cells, the unit supplies commanded torque and velocity for axes that require accurate positioning.
During continuous operation, the motor delivers a rated mechanical output of 750 W at a shaft torque of 2.39 N·m while drawing 4.6 A RMS from a 200 V three-phase bus. These values indicate the sustained workload that the drive and machine can support without overheating. Feedback resolution reaches 131072 divisions per revolution, so the controller can command moves as small as 2.7 arcseconds, improving repeatability on pick-and-place stages. The phase resistance is 0.4 Ω, which limits copper loss and influences the current rise time when the amplifier applies voltage to the windings.
Under transient loads, the shaft can reach a peak torque of 8.5 N·m and accelerate to 6000 rpm, allowing short bursts to overcome friction or drive indexing cams. A continuous stall torque of 2.55 N·m provides capacity for static holding loads when motion is paused and the motor remains energized. The torque constant of 0.559 N·m/A RMS relates current commands to the torque developed within the control loop. Peak current is limited to 15.5 A RMS, preventing the amplifier and windings from exceeding their short-term current limit. The rotor inertia of 1.82 × 10⁻⁴ kg·m² supports responsive yet stable acceleration profiles for medium-mass tooling used in packaging, assembly, and inspection equipment.
