Product Description:
The R2AA06040FCPPW is a medium-inertia AC servo motor produced by Sanyo Denki for the R SANMOTION Servo Motors series. Designed for 200 V drive systems, it provides closed-loop shaft control for positioning tables, pick-and-place heads, and other automated axes. A built-in 24 VDC holding brake secures the load when power is removed, while the 60 mm mounting flange supports installation with compact gearboxes or direct-drive couplings. Battery-backed absolute feedback retains position information during shutdowns, and the moderate rotor inertia supports precise starts and stops without requiring a separate external encoder.
The motor provides a rated mechanical output of 400 W at a shaft speed of 3000 rpm. Under these operating conditions, it produces 1.27 N·m of torque while drawing 2.8 A RMS from a 200 V supply. The torque constant is 0.524 N·m/A RMS, linking commanded phase current to the torque generated by the motor. A phase resistance of 1.36 Ω affects copper losses and must be considered when selecting a compatible drive. The voltage constant is 18.3 mV/rpm, which affects the back electromotive force generated as shaft speed increases. Dynamic response is supported by a rotor inertia of 0.415 × 10⁻⁴ kg·m², while the square 60 mm flange centers the motor accurately on the machine frame.
During short acceleration periods, the motor can produce a peak torque of 4.8 N·m and reach a maximum speed of 6000 rpm. The electromagnetic brake provides 1.37 N·m of static holding torque and disengages in 30 ms, allowing indexed movement to resume shortly after power is applied. Position feedback is supplied by a 131,072 P/R battery-backed absolute encoder, enabling the control system to retain the shaft position after a shutdown. The high encoder resolution supports accurate position regulation during rapid motion, while the available peak torque assists with brief changes in load and acceleration demand.
