Product Description:
The R2AA08075FXP00 servo motor is manufactured by Sanyo Denki within the R SANMOTION Servo Motors series. This rotary actuator is intended for positioning axes that demand moderate continuous power and quick dynamic response in industrial automation. Integrated feedback is provided by a battery-backed absolute encoder, so a controller can recover the shaft position after power is restored, simplifying restart procedures in packaging, electronics assembly, and similar automated stations.
At its nominal operating point, the motor delivers 750 W of mechanical power when supplied from a 200 V drive bus. The continuous operating point provides a rated shaft torque of 2.39 N·m with a phase current of 4.6 A RMS. Within this operating range, the rotor can reach 6000 rpm, permitting small-frame machinery to achieve high throughput. The 80 mm square flange matches common compact gearheads, while the medium-inertia rotor balances smooth acceleration with load matching. A phase resistance of 0.4 Ω keeps copper loss moderate. Position feedback provides 17-bit single-turn and 16-bit multi-turn resolution, giving controllers precise angular data across 131,072 counts per turn and 65,536 revolutions.
A 2.55 N·m continuous stall rating lets the shaft maintain position without overheating when ventilation is limited. During acceleration, the drive may command up to 8.5 N·m, and this temporary overload requires a phase current of 15.5 A RMS that remains within the inverter’s short-term limits. The electromagnetic design generates torque in proportion to current at 0.559 N·m/A RMS, allowing predictable control tuning. Because a holding brake is not installed, the application must rely on servo lock or an external clamp for power-off restraint. The rotor inertia is 1.823 × 10⁻⁴ kg·m², supporting responsive speed changes while damping oscillations in belt-driven or screw-driven axes. This inertia level also helps the motor accommodate compact transmission components without sacrificing controlled acceleration under changing loads.
