Product Description:
The R2AA18350DCP0E is a middle-inertia AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. It converts current from a compatible servo drive into controlled mechanical rotation for positioning and speed-control axes in industrial automation. Its inertia profile balances responsive acceleration with stable motion under changing loads. The motor is suitable for indexing tables, gantries, tooling spindles, and other machinery that requires precise rotary motion.
The motor coils operate with a 200 V class bus and draw a rated current of 21.7 A RMS to deliver 3.5 kW of continuous mechanical power at the shaft. Under nominal operating conditions, the rotor turns at 2,000 rpm and produces 17.0 N·m of torque. Transient moves can draw a peak current of 83.0 A RMS, allowing the motor to produce up to 60.0 N·m of peak torque for short periods. When stalled, the windings tolerate 27.0 A RMS while maintaining 22.0 N·m of torque without exceeding their thermal limits. This current and torque capacity supports repetitive acceleration, deceleration, and positioning cycles in general-purpose servo applications. Compatible SanMotion R drive amplifiers regulate the motor current according to the commanded speed, torque, and position.
The motor has a 180 mm square flange for mounting to a machine frame or gearbox. Its rotor has an inertia of 40 × 10⁻⁴ kg·m², which helps suppress rapid load disturbances while retaining useful acceleration performance. A 24 VDC holding brake provides 22 N·m of friction torque to secure the shaft when brake power is removed. The brake operates from a dedicated 24 VDC circuit and can prevent vertical loads or tooling from drifting while the drive is disabled. Position feedback comes from a battery-backed absolute encoder with a single-turn resolution of 131,072 counts per revolution and a multi-turn range of 65,536 revolutions. The stored absolute position allows the controller to recover the axis location after a power interruption without requiring a new homing cycle.
