Product Description:

The R2AA18350LXP00M is a medium-inertia AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. With a 180 mm square mounting flange and a mass of 15.5 kg, it fits medium-frame drive systems where inertia matching is required for positioning tables, packaging axes, or pick-and-place gantries. CE and UL listings confirm compliance with common safety and emissions requirements, while the lack of an integral holding brake favors installations that use external clamps or motor torque for static retention. In industrial automation, the unit converts regulated drive current into controlled shaft motion along closed-loop position or speed profiles.

Under continuous load, the motor delivers 17.0 N·m of shaft torque at a rated speed of 2000 rpm, producing 3.5 kW of mechanical power while drawing a rated armature current of 19.1 Arms from a 6.0 kVA drive. The standard design sustains a continuous stall torque of 22.0 N·m, and the windings accept 23.7 Arms at stall without exceeding their temperature class. These values reflect the thermal balance between copper losses and heat dissipation through the motor frame. Torque remains smooth because the rotor inertia of 40 × 10⁻⁴ kg·m² helps damp minor load disturbances without excessively slowing the servo response.

For peak moves, the drive may supply 55.0 Arms, allowing the motor to reach a maximum torque of 49.0 N·m and accelerate connected loads to a maximum speed of 3000 rpm. Feedback is provided by a battery-backed absolute encoder with a resolution of 131,072 divisions per revolution, preserving position through power cycles across a multi-turn range of 65,536 revolutions. The high encoder resolution supports precise position tracking and smooth speed regulation during rapid changes in load or command velocity. The power terminals are rated for 200 V, making the motor compatible with corresponding industrial servo drive systems.
