Product Description:

Sanyo Denki manufactures the R2AA08075FCP00 as part of its R SANMOTION Servo Motors series. This medium-inertia servo motor is intended for positioning and speed-control duties in automated machinery, where closed-loop accuracy and short settling times are important. A built-in 24 VDC holding brake maintains the load position when power is removed. The motor has an 80 mm mounting flange that fits compact motion axes and compatible machine interfaces.

The motor delivers a continuous mechanical output of 750 W at a rated shaft torque of 2.39 N·m when supplied from a 200 V bus. Transient demands can be met because peak torque reaches 8.5 N·m, supporting rapid acceleration during short motion cycles. The rotor can accelerate to 6000 rpm without exceeding the motor’s maximum speed limit. The standard frame has an overall length of 143 mm, which reduces the installation depth while providing the active stack length needed for continuous heat dissipation. Its square-face mounting pattern allows couplings and gearheads with matching pilot diameters to be installed without adapters. This format is appropriate for pick-and-place gantries, indexing tables, and other mid-range motion axes that require controlled speed and repeatable positioning.

The housing has an IP67 protection rating, sealing the stator against dust ingress and temporary water immersion. A battery-backed absolute encoder supplies 131072 counts per revolution of position data, allowing the drive to recover axis coordinates after a power failure. The holding brake releases in 40 ms and applies in 20 ms, helping the axis transition promptly between stationary and powered operation. Its static friction torque is 2.55 N·m, which allows the brake to secure vertical loads while the motor is unpowered. Rotor inertia is limited to 1.823 × 10⁻⁴ kg·m², providing a balance between responsive acceleration and mechanical damping. The integrated encoder supports closed-loop motion control without requiring a separate external position sensor.
