Product Description:

The R2AA08020FCPKB is a servo motor produced by Sanyo Denki and supplied under the R SANMOTION Servo Motors series. As a mid-inertia rotary actuator, it converts drive current into controlled mechanical rotation. The motor supports positioning, conveying, and indexing tasks in automated machinery where stable acceleration and precise motion control are required.

The motor is designed for a bus voltage of 200 V and draws a nominal phase current of 1.5 A rms. At that operating point, it delivers 200 W of mechanical power with a continuous rated torque of 0.637 N·m. The torque constant of 0.516 N·m/A rms indicates the relationship between stator current and developed shaft torque; along with a phase resistance of 2.3 Ω, this value supports accurate drive-amplifier current-loop tuning. An 80 mm flange simplifies direct mounting to compact gearheads, and the rotor inertia of 0.523 × 10⁻⁴ kg·m² provides a balance between fast acceleration and stable velocity regulation. The built-in battery-backed absolute encoder records 65,536 multi-turn revolutions, allowing the controller to retain position after power loss.

The unit can accelerate to a peak torque of 2.2 N·m and sustain mechanical speeds up to 6,000 rpm for short motion intervals. A continuous stall torque of 0.686 N·m enables static load holding without thermal overload. Positional feedback for each revolution is resolved into 131,072 divisions/rev, supporting tight loop gains when gearing converts rotary motion into sub-micrometer linear travel. A 24 VDC holding brake provides 2.55 N·m of static braking torque and arrests the shaft within 40 ms, preventing back-driving on vertical axes. The brake uses the same voltage as many machine control supplies, which simplifies power distribution and wiring. The encoder resolution, moderate rotor inertia, and integrated brake support quick settling and repeatable positioning in pick-and-place heads, semiconductor stages, and light material-handling axes.
