Product Description:
The R2AA13120LCP2E is a medium-inertia servo motor manufactured by Sanyo Denki for the R SANMOTION Servo Motors series. It delivers closed-loop rotary motion for automated machinery, and its battery-backed absolute encoder preserves position data across power cycles so axes can return to service without a homing routine. By combining mechanical power output with digital feedback in one frame, the motor simplifies integration into positioning tables, pick-and-place gantries, and conveyor lines.
The stator windings are designed for a three-phase AC supply of 200 V. At this voltage, the unit produces a continuous mechanical output of 1.2 kW while operating at a rated speed of 2000 rpm. Current draw at that operating point is 7.6 A rms, and the electromagnetic system converts each ampere into torque at a constant of 0.77 N·m/A rms. This produces a rated shaft torque of 5.7 N·m, which is suitable for driving moderate-load rotary actuators without additional gear reduction. The phase resistance is 0.35 Ω, allowing power losses and drive requirements to be calculated from the listed current. The encoder provides 16-bit multi-turn resolution and 17-bit single-turn resolution, supporting precise position feedback for finely controlled motion profiles.
A normally engaged holding brake supplies 9.0 N·m of static torque and releases within 100 ms when its 24 VDC coil is energized. The brake voltage matches the control supply commonly available in industrial cabinets. The square flange measures 130 mm and aligns with IEC mounting interfaces, while the motor body weighs 6.1 kg. During acceleration, the rotor has an inertia of 6.0 × 10⁻⁴ kg·m², allowing quick speed changes without excessive drive current. The maximum mechanical speed is 3000 rpm, providing a 1.5-to-1 margin above the rated operating speed for transient motion peaks. The normally engaged brake holds the shaft when coil power is removed, helping prevent unintended movement while the axis is stopped.
