Product Description:
The R2AA08075FCH11 is a medium-inertia AC servo motor produced by Sanyo Denki as part of the R SANMOTION Servo Motors series. Built for closed-loop motion axes, it drives precision fixtures, pick-and-place heads, indexing tables, conveyor diverters, and press feeders. The motor converts regulated electrical power from a compatible servo amplifier into controlled torque and speed. Its balanced rotor inertia supports responsive acceleration while maintaining stable operation with moderate-mass loads. The compact housing also allows the motor to fit into automated equipment where installation space is limited.
The motor is designed for 200 V operation and delivers a continuous mechanical output of 750 W. At its rated operating point, the shaft turns at 3000 rpm, produces 2.39 N·m of torque, and draws 4.6 A RMS per phase. Its torque constant is 0.559 N·m/A RMS, relating commanded phase current to the torque developed at the shaft. A phase resistance of 0.4 Ω contributes to copper losses and affects the rate at which current rises in the windings. The voltage constant is 19.5 mV per rpm, indicating how the motor’s back electromotive force increases with rotational speed. These electrical characteristics allow the connected amplifier to regulate current accurately throughout the operating speed range.
For short acceleration periods, the motor can produce a peak torque of 8.5 N·m and reach a maximum speed of 6000 rpm. An integrated 24 VDC holding brake supplies 2.55 N·m of static torque and prevents the shaft from drifting after motor power is removed. The brake coil can connect to the machine’s 24 V utility supply, which keeps the brake circuit separate from the motor power conductors. Position feedback is provided by an absolute encoder with a resolution of 131,072 counts per revolution, allowing the servo drive to detect small changes in shaft position. The output shaft has a nominal diameter of 16 mm with a -0.011 mm tolerance for accurate coupling alignment. The motor mounts through an 80 mm square flange that supports a compact installation footprint and secure attachment to the machine frame.
