Product Description:
The R2AA04003FXP00M is an AC servo motor in the R SANMOTION Servo Motors series manufactured by Sanyo Denki. Classified as a medium-inertia model, it is intended for light-duty industrial automation applications where smooth acceleration and accurate positioning are required. The battery-backed absolute encoder attached to the shaft allows control systems to track machine position even after a power loss, making the unit suitable for pick-and-place tables, indexers, and small transfer stations. Retaining position data can also reduce the need to repeat homing procedures after power is restored.
During continuous operation, the motor delivers an output of 30 W while sustaining 0.098 N·m of rated torque at the shaft. These values are reached with a phase current of 0.51 A rms, so standard low-power amplifiers can drive the unit without being oversized. The stator windings are designed for a 200 V bus, matching the common supply level of Sanyo Denki R-series amplifiers. When commanded to its limit, the rotor can reach 6000 rpm, providing high linear speed when coupled to small gearheads or belt-driven stages. The phase resistance is 12 Ω at 20 °C, which helps keep copper losses modest during dwell periods and provides a useful electrical reference for selecting a compatible drive.
At standstill, the motor can hold a stationary load with a continuous stall torque of 0.108 N·m. It can also produce up to 0.37 N·m of torque for brief movements without demagnetization. This reserve is supported by a torque constant of 0.201 N·m/A rms, reducing drive-current demand during fine positioning. Dynamic response is aided by an electrical time constant of 0.55 ms, allowing the current loop to settle quickly when the controller issues rapid corrections. A flange dimension of 40 mm simplifies mounting on compact machinery frames, while the lack of a holding brake reduces inertia for faster start-and-stop cycles. CE and UL compliance supports use in equipment intended for markets that recognize these approvals.
