Product Description:

The R2AA08075FCH00M is a servo motor built by Sanyo Denki for the R SANMOTION Servo Motors series. It is intended for motion axes that require midrange power and high positional accuracy in industrial automation equipment. A middle-inertia rotor balances quick acceleration with load stability, while the absolute encoder provides 131,072 counts per revolution so the controller can close position loops without an external reference mark. An integrated 24 V DC holding brake locks the shaft when power is removed. The motor also meets applicable CE and UL requirements for use in industrial machinery.

This model is rated for a continuous shaft output of 750 W at a nominal torque of 2.39 N·m. When driven from a 200 V supply, it can reach speeds up to 6000 rpm, making it suitable for indexing tables and packaging spindles. The housing has an ingress protection rating of IP67, allowing operation in dusty areas or environments where washdown occurs. Mechanical mounting uses a square pattern with a flange size of 80 mm, simplifying installation with compatible frame-80 equipment. The phase resistance is 0.4 Ω, and the voltage constant is 19.5 mV/(min⁻¹), which the drive must accommodate when generating sinusoidal outputs.

Dynamic limits include a continuous stall torque of 2.55 N·m and a peak torque of 8.5 N·m for short acceleration bursts. The rated current is 4.6 Arms, while the inverter must permit a peak current of 15.5 Arms to use the full overload range. A torque constant of 0.559 N·m/Arms relates commanded current to developed torque and supports feedforward tuning. The motor is supplied in the standard version and uses a fully sealed stator that withstands coolant splash. A sealed circular connector carries the three motor phases and encoder channels. The integrated brake supports load retention during power loss, while the high-resolution feedback system provides the position data needed for controlled step-and-settle motion.
