R2AA04005FXPCB

The Sanyo Denki R2AA04005FXPCB AC servo motor from the R SANMOTION Servo Motors series offers a compact, high-performance solution delivering a rated output of 50W and a rated speed of 3000 rpm for precise industrial automation. Engineered by Sanyo Denki, this motor achieves a rated armature current of 0.67 Arms and supports a peak torque at stall of 0.59 N·m, providing reliable power in dynamic motion systems. It features a torque constant of 0.246 N·m/Arms and a voltage constant per phase of 8.6 mV/rpm, ensuring efficient conversion of electrical input to mechanical output. The robust construction and integrated encoder support deliver accurate position feedback and low power consumption under continuous operation.

In-depth specifications highlight the motor’s electrical and mechanical characteristics: it exhibits an armature current at stall of 0.69 Arms and a continuous torque at stall of 0.167 N·m for sustained holding tasks. The electrical time constant of 0.67 ms and mechanical time constant of 1.7 ms define its rapid current response and rotor acceleration profiles. With a peak armature current at stall of 2.8 Arms, the R2AA04005FXPCB can endure short bursts of high load without thermal overload. The phase resistance of 9 Ω ensures stable winding temperatures and predictable voltage drops under load. Delivering a rated torque of 0.159 N·m and an effective rated power rate of 6.7 kW/s, this servo motor maintains consistent performance across varying duty cycles.

Operational features emphasize responsive control and durability: the integrated encoder feedback system enables real-time speed and position monitoring, reducing cumulative error in repetitive tasks. Its low inertia and fast time constants facilitate precise acceleration and deceleration, essential for high-speed pick-and-place or indexing operations. Thermal stability is maintained through optimized winding design, minimizing drift during prolonged runs. The motor supports peak torque demands at stall and recovers quickly thanks to a controlled electrical time constant, ensuring reliable response even under rapid load changes.

System integration of the R2AA04005FXPCB leverages compatibility with standard servo drives and motion controllers, simplifying commissioning in automated lines and robotic platforms. Its compact footprint and 50W class power make it ideal for space-constrained machine tools, laboratory automation, and conveyor indexing stations. The robust feedback loop supports advanced motion algorithms, including torque control and vector drive modes. Target applications include precision assembly, packaging machinery, semiconductor handling, and any industrial automation scenario demanding accurate, repeatable motion.
