Product Description:
The R2AA06040FXSC9 is a medium-inertia AC servo motor manufactured by Sanyo Denki for the R SANMOTION Servo Motors series. It is intended for positioning and speed-control axes in industrial automation. The motor couples directly to gearboxes or load shafts through its 60 mm square flange, converting drive current into precise mechanical rotation for robots, conveyors, and compact machine tools.
During continuous duty, the motor provides a rated mechanical output of 400 W. At this operating point, it draws a phase RMS current of 2.8 Arms from a three-phase bus rated at 200 V, delivers a shaft speed of 3000 rpm, and produces 1.27 N·m of torque. These nominal values indicate the steady-state load that the drive can supply without exceeding the motor’s thermal limits. The phase resistance is 1.36 Ω, which contributes to copper losses that the frame dissipates through natural convection. A torque constant of 0.524 N·m/Arms relates commanded current to developed torque. The voltage constant of 18.3 mV/rpm relates back electromotive force to shaft speed. These electrical parameters allow compatible drive amplifiers in the SANMOTION R platform to regulate the current loop with predictable gain.
At zero speed, the motor can sustain a continuous stall torque of 1.37 N·m. For brief acceleration periods, it can reach a peak torque of 4.8 N·m. Maximum mechanical speed is limited to 6000 rpm, and reaching this speed requires no more than 10.8 Arms of peak phase current. The rotor inertia of 0.412 × 10⁻⁴ kg·m² moderates acceleration and contributes to stable response during point-to-point moves. Because a holding brake is not installed, static load retention must be provided by the drive or external mechanical components. Position feedback is supplied by a wire-saving incremental encoder that reduces the cable count on moving axes. The 60 mm flange supports installation in compact equipment, while the medium-inertia rotor is suited to small manipulators that require moderate load-inertia matching.
