Product Description:

The R2GA04005FXP00 is a servo motor produced by Sanyo Denki within the R SANMOTION Servo Motors series. This medium-inertia unit attaches to machinery through a 40 mm square flange and comes in the standard configuration without an integrated holding brake. A battery-backed absolute encoder maintains position data after a power loss, eliminating the need for homing at startup. The motor is intended for compact industrial axes that require consistent torque delivery and precise position control in assembly, inspection, and pick-and-place equipment.

At its rated operating point, the motor provides 50 W of mechanical output at a nominal speed of 3000 rpm. This operating point produces a shaft torque of 0.159 N·m when the drive supplies 3.8 Arms to the windings. The torque constant of 0.047 N·m/Arms relates commanded current to produced torque, enabling precise drive regulation. A rated power rate of 6.7 kW/s indicates how quickly the motor can accelerate, while a phase resistance of 0.33 Ω determines copper losses during acceleration. The rotor inertia is 0.0376 × 10⁻⁴ kg·m², which helps reduce settling time after rapid movement. The absolute encoder offers a single-turn resolution of 131,072 counts, or 17 bits, supporting fine interpolation for high-precision motion profiles.

The continuous stall capacity reaches 0.167 N·m, allowing the axis to hold static loads without overheating. Short-term overloads are supported by a peak stall torque of 0.54 N·m, providing additional torque during acceleration or temporary load changes. The motor can operate at speeds up to 6000 rpm without triggering an overspeed alarm. Multi-turn tracking covers 65,536 revolutions (16-bit), preserving absolute position across long movements or repeated power cycles. This position range allows the controller to monitor extensive axis travel without requiring the encoder count to be reset after normal shutdowns.
