Product Description:
The R2AA06040FXP00 is a servo motor from Sanyo Denki that belongs to the R SANMOTION Servo Motors series. With a 60 mm mounting flange and a middle-inertia rotor, the unit is sized for compact pick-and-place axes, packaging feeders, and other precision machines. It employs a battery-backed absolute encoder capable of tracking up to 65,536 revolutions, allowing controllers to recover position after a power loss without requiring a homing cycle. Within an automation cell, the motor converts electrical power from a compatible drive into controlled mechanical motion. Its compact frame supports installation where available mounting space is limited.
During continuous operation, the motor delivers a rated mechanical output of 400 W at a supply voltage of 200 V. Its electromagnetic design produces a rated torque of 1.27 N·m while drawing a rated armature current of 2.8 A RMS. These values indicate the steady-state operating point used for drive sizing and thermal load calculations. The encoder provides position feedback at a resolution of 131,072 divisions per revolution, supporting fine velocity control and smooth interpolation. Phase resistance is 1.36 Ω, and the torque constant is 0.524 N·m/A RMS, linking commanded current to shaft torque during current-mode control. This feedback also helps the drive maintain accurate positioning during changes in speed and load.
Dynamic motion is supported by a continuous stall torque of 1.37 N·m and a peak torque limit of 4.8 N·m. Transient peaks are reached when the drive supplies up to 10.8 A RMS, enabling rapid acceleration of the 0.415 × 10⁻⁴ kg·m² rotor and the attached load. The maximum mechanical speed is 6,000 rpm, which accommodates gearless coupling in high-speed conveyor applications. The motor is supplied without a holding brake, so external clamping is required when the shaft must remain locked after power is removed. The middle-inertia rotor provides a balance between responsive acceleration and load stability. Its absolute feedback system retains multi-turn position data across extended machine travel.
