Product Description:
The R2AA08075FXP29 servo motor is produced by Sanyo Denki for the R SANMOTION Servo Motors series. Classified as a medium-inertia rotor unit, it is intended for axes that demand a balanced response between acceleration and load stability. Within industrial automation lines, the motor converts regulated electrical power from a matched SANMOTION amplifier into repeatable rotary motion, allowing conveyors, packaging spindles, and positioning tables to follow motion profiles with precise speed and torque control.
The motor delivers a continuous mechanical output of 750 W when supplied by a 200 V three-phase source. At this rating, it draws a phase current of 4.6 A rms, producing 2.39 N·m of torque at a nominal speed of 3,000 rpm. A battery-backed absolute encoder mounted on the shaft reports position with a single-turn resolution of 131,072 counts per revolution and tracks up to 65,536 revolutions for position recovery after power is restored. The motor can accelerate to a maximum speed of 6,000 rpm, allowing rapid movement during time-sensitive operating cycles. Rotor inertia is 1.823 × 10⁻⁴ kg·m², which supports tuning with moderate load-to-motor inertia ratios. Mechanical power is transmitted through a 16 mm keyed shaft. The motor does not include a holding brake, so an external brake or another holding mechanism is required when an unpowered axis must remain stationary.
During transient operation, the drive may supply a phase current of 15.5 A rms, enabling the motor to reach a peak torque of 8.5 N·m without losing synchronism. During sustained low-speed operation, the motor can maintain a continuous stall torque of 2.55 N·m, supporting applications that hold static loads, such as indexing fixtures. The square mounting flange measures 80 mm, allowing alignment with compatible gearheads and couplings while supporting consistent mounting across similar machine assemblies.
