Product Description:

The R2AA08075FXH00W is a medium-inertia AC servo motor manufactured by Sanyo Denki for the R SANMOTION Servo Motors series. Intended for closed-loop motion axes in machine tools and electronics assembly lines, the unit connects to a compatible drive and converts electrical commands into precise rotary torque and speed. Its 80 mm mounting flange provides a compact mechanical interface for automated equipment with limited installation space. Integrated position feedback supports repeatable positioning and rapid acceleration in applications such as indexing tables, component handlers, and production machinery.

With a supply voltage of 200 V, the motor delivers a continuous mechanical output of 750 W while drawing a rated phase current of 4.6 A RMS. The shaft operates at a nominal speed of 3000 rpm and produces a continuous torque of 2.39 N·m. Momentary load changes are supported by a peak current of 15.5 A RMS, allowing rapid acceleration without exceeding the motor’s short-term operating limits. The motor does not include a holding brake, so static load retention must be provided by drive-applied torque or an external clamping device. Its maximum no-load speed is 6000 rpm, providing additional speed range above the nominal operating point.

Short-duration overloads are supported by a peak torque of 8.5 N·m, providing increased torque for acceleration and indexing moves. The rotor has an inertia of 1.82 × 10^-4 kg·m², balancing responsive acceleration with controlled stopping on medium-mass axes. A phase resistance of 0.4 Ω provides an electrical value used when matching the motor with a suitable servo drive and selecting appropriate cabling. The absolute encoder provides a resolution of 131,072 divisions per revolution, enabling fine position measurement for high-precision control loops. The motor also has a stall torque of 2.55 N·m and a mass of 2.7 kg. Its configuration follows the standard SanMOTION build format for this motor series.
