Product Description:

The R2AA06040FXP00M is a servo motor manufactured by Sanyo Denki for the SANMOTION R Servo Motors series. It is installed in automated systems to deliver controlled rotary motion under drive commands, enabling accurate indexing, feeding, and positioning functions. Integration with a feedback encoder and compatible drive supports the closed-loop regulation required by modern production machinery.

The motor provides a rated mechanical output of 400 W and continuously delivers 1.27 N·m of rated torque. During rapid acceleration, the shaft withstands a peak stall torque of 4.8 N·m, providing additional capacity to overcome friction or momentary load spikes. Its speed reaches 6000 rpm, allowing the motor to serve high-throughput axes without gear reduction. The winding is designed for a 200-volt class bus, allowing direct connection to standard SANMOTION R amplifiers. The medium-inertia rotor balances quick response with load matching in midsize mechanisms, while the standard configuration uses the baseline thermal design without special coatings. CE and UL approvals support integration into compliant control systems. The motor does not include a holding brake, reducing its overall length where static shaft locking is unnecessary.

Position feedback is generated by a 17-bit battery-backed absolute encoder that reports up to 131,072 counts per revolution and tracks a multi-turn total of 65,536 turns. This encoder retains position information after power loss, allowing operation to resume without a new homing cycle. The housing has a 60 mm square flange and a keyless output shaft, simplifying connection to rigid clamping hubs and eliminating fretting associated with keyed joints. With a mass of only 1.4 kg, the assembly helps keep moving weight low. The rotor inertia is 0.4153 × 10⁻⁴ kg·m², supporting stable velocity regulation in medium-load applications. No oil seal is fitted, so external sealing is required if the shaft extends into an area exposed to oil or other fluids.
