Product Description:

The R2AA13120BXH00M is a servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. This model has a standard configuration and belongs to the middle-inertia class, providing a balance between rapid acceleration and load tolerance. Compliance with CE and UL standards allows installation in equipment intended for international markets. When paired with a compatible amplifier, the unit supplies programmable torque and speed so automated transfer lines, index tables, and packaging axes can reach commanded positions with repeatable accuracy.

Position feedback is delivered by a single-turn absolute encoder with a resolution of 131072 counts/rev. Because multi-turn tracking is not provided, the controller must reference the axis after power-up. A square mounting interface measuring 130 mm on each side aligns the frame with standard machinery. During transient moves, the shaft can generate 16.0 N·m of peak torque, while a continuous current of 5.2 Arms supports a mechanical output rating of 1.2 kW. The torque constant is 1.09 N·m/Arms, allowing the drive to coordinate current commands with the requested torque. A holding brake is not installed, so external clamping is required for vertical loads when power is removed. The shaft does not have an oil seal, making the motor suitable for cabinets or other protected areas.

During routine operation, the rotor produces 5.7 N·m of rated torque. The winding provides an acceleration capacity of 54 kW/s when supplied from a 200 V bus. Stator copper loss is influenced by a phase resistance of 0.64 Ω, which the drive uses when estimating thermal rise. The generated back electromotive force follows a voltage constant of 37.8 mV per min⁻¹, allowing the servo amplifier to calculate field-oriented control vectors throughout the operating speed range.
