R2AA08040FXP00

The R2AA08040FXP00 AC servo motor exemplifies Sanyo Denki’s precision-driven design within the R SANMOTION Servo Motors series by Sanyo Denki. It delivers a Rated Output of 400W and operates at a Rated Speed of 3000 min⁻¹, providing a Rated Torque of 1.27 N·m for compact, high-efficiency applications. Its Peak Torque At Stall rating of 2.39 N·m and Continuous Torque At Stall of 1.37 N·m ensure robust handling of variable loads. The motor’s Rotor Moment Of Inertia (not Including Encoder) of 0.060 ×10⁻⁴ kg·m² contributes to agile dynamic response, while the Phase Resistance of 0.44 Ω supports stable current flow under load. Designed for industrial automation, this motor balances power density with compact dimensions for seamless system integration.

Performance is optimized through a precise Torque Constant of 0.582 N·m/Arms and a Voltage Constant Per Phase of 20.3 mV/min⁻¹, delivering predictable torque generation per ampere. The Rated Armature Current of 3.92 Arms and maximum Armature Current At Stall rating of 4.8 Arms enable consistent acceleration, with a peak Peak Armature Current At Stall of 14.3 Arms available for demanding startup conditions. These electrical characteristics, combined with a finely tuned winding design, minimize heat generation and ensure efficient power conversion. The motor’s response characteristics support precise motion control in high-speed indexing and positioning tasks. Coupled with advanced feedback integration, these technical features deliver smooth velocity profiles and exceptional repeatability.

Built for reliability in industrial environments, the R2AA08040FXP00 operates across an Operating Temperature range of 0 to 40°C, maintaining consistent performance in standard factory conditions. Integration is streamlined with its compact footprint and standardized mounting dimensions, facilitating easy retrofits into existing automation platforms. For feedback and position accuracy, an optional PA035C absolute encoder provides 131,072 (17-bit) partition resolution and 65,536 (16-bit) multi-turn support, secured by a battery backup system to retain positional data during power interruptions. This robust feedback solution enhances system resilience and eliminates the need for re-homing after outages. Ideal for robotics, packaging machinery, and semiconductor equipment, the R2AA08040FXP00 delivers reliable, high-precision performance in critical industrial applications.
