R2GA04005FXH00M
by Sanyo Denki
The Sanyo Denki R2GA04005FXH00M AC servo motor is a high-precision, compact drive solution engineered for industrial automation and motion control. Part of the R SANMOTION Servo Drives series, this motor provides a rated output of 50W and delivers a rated torque of 0.159 N·m at its rated speed of 3000 min⁻¹. Designed by Sanyo Denki, the R2GA04005FXH00M features an optimized electromagnetic structure and advanced winding techniques to achieve high efficiency and rapid response in a lightweight form factor. Its robust construction enables reliable operation in demanding manufacturing and robotics environments, ensuring precise positioning and smooth torque delivery. The motor’s slim profile and integrated encoder interface simplify mechanical integration into compact assemblies.
The R2GA04005FXH00M combines a torque constant of 0.246 N·m/Arms with a voltage constant per phase of 8.6 mV/min⁻¹ to ensure stable electromechanical conversion across a wide range of speeds. It exhibits a phase resistance of 9 Ω and operates at a rated armature current of 0.67 Arms with a peak capability reaching a stall armature current of 0.69 Arms. The rotor dynamics are characterized by a rotor moment of inertia of 0.0376 × 10⁻⁴ kg·m², supporting rapid accelerations and decelerations without overshoot. Under high-load conditions, the motor maintains a continuous torque at stall of 0.167 N·m and can deliver a peak torque at stall of 0.59 N·m for brief periods to handle transient loads. These core specifications are optimized to deliver consistent performance in precision assembly, pick-and-place, and CNC applications.
Operational resilience is enhanced by an integrated electromagnetic brake rated for DC 90V/DC 24V ±10%, providing secure holding torque when power is removed or during emergency stops. The motor is qualified for continuous operation within an operating temperature range of 0 to 40°C, ensuring stable performance under typical factory conditions. Weighing just 0.39 kg including the encoder, the R2GA04005FXH00M supports lightweight designs and reduces inertial loading on machine structures. Its fast current control loop and low rotor inertia enable high responsiveness, while the efficient thermal path maintains safe operating temperatures during extended duty cycles.
System integration is streamlined through a standardized flange and cable connector arrangement compatible with Sanyo Denki’s R SANMOTION auxiliary modules and controllers. No specialized adapters are required to implement auto-tuning, position feedback, and error diagnostics within existing motion control architectures. The compact dimensions and comprehensive accessory support make the R2GA04005FXH00M ideal for robotics, semiconductor handling, medical devices, and compact CNC machinery. Field applications benefit from reduced commissioning times, predictable dynamic behavior, and seamless compatibility with third-party servo amplifiers when following the manufacturer’s accessory guidelines.
