The YASKAWA SGMRV-13ANA-YR1D is an industrial AC servo motor built for closed-loop motion tasks where positioning accuracy, repeatability, and torque stability matter more than “it spins, therefore it’s fine.” In real factories, that usually means multi-axis automation, precision handling, and robot-axis duty where the motor has to accelerate, stop, and hold position thousands of times a shift without slowly turning into a space heater.
SGMRV motors are commonly discussed in the context of Yaskawa’s servo ecosystem (often referenced alongside Sigma-series servo systems). In Yaskawa Motoman’s parts catalog, a closely related SGMRV-13ANA-YR1* variant is described as an AC servo motor in the Sigma-5 context and identified as 1.3 kW class.
Quick Technical Snapshot (Readable, Not “Mystical”)
| Item | What it means for you |
|---|---|
| Model | SGMRV-13ANA-YR1D |
| Motor type | AC servo motor (closed-loop motion) |
| Power class | 1.3 kW (same family/variant listing) |
| Typical use context | Robot axes / industrial automation servo axis |
| Continuous speed reference (related variant) | 1500 min⁻¹ shown on a dimension/spec sheet for SGMRV-13ANA-YR11 |
| Net Weight (motor) | Approx. 12 kg |
| Packaged weight (related variant listing) | Approx. 15.6kg |
Weight note (honest version): public listings for SGMRV-13ANA-YR1D/YR1* variants don’t always agree. For your listing, it’s safer to present “Approx. 12 kg (typical; may vary by brake/shaft options)” and keep the variant reference as a footnote rather than pretending the number is a law of physics.
What This Motor Is Good At (And Why That Matters)
Servo motors earn their keep by doing three things well:
-
Produce usable torque across dynamic motion
In a servo axis, “rated power” is less important than how controllable the torque is during acceleration, deceleration, and holding. The SGMRV family is positioned for demanding motion control where stability beats raw peak speed. -
Respond quickly to command changes
Servo performance is about the motor-drive-feedback loop acting like a disciplined nervous system. In Sigma-series ecosystems, Yaskawa’s catalogs and manuals emphasize system-level design for servo performance (motor + amplifier/drive + tuning tools), not the motor as a lone hero. -
Stay consistent over long duty cycles
Robotics and automation don’t forgive thermal drift or sloppy mechanical behavior. A servo motor in this class is typically selected because it can run for long periods with repeatable motion quality.
Typical Application Fit
| Application | Why SGMRV-13ANA-YR1D makes sense | Practical selection reminders |
|---|---|---|
| Robot axis replacement / maintenance stock | Model family is explicitly used in Yaskawa Motoman robot parts contexts | Match the exact suffix and feedback/brake configuration |
| Rotary positioning tables / indexing axes | 1.3 kW class is commonly used for medium-duty rotary axes | Confirm inertia ratio and gearbox/backlash constraints |
| Machine automation (handling, pick/place, fixtures) | Servo control gives repeatable stop-and-hold positioning | Verify mounting dimensions, shaft type, and cabling |
| Retrofit projects | Stable servo ecosystem support (catalog + manuals) | Confirm drive compatibility and connector/cable standards |
Integration Notes (The Stuff That Prevents Pain Later)
Drive and feedback compatibility
This motor is designed to operate as part of a Yaskawa servo system—meaning the servo amplifier/drive and feedback interface are not optional details. When you spec or list it, you should avoid overpromising “universal compatibility.” A correct, search-friendly phrasing is:
-
“Compatible with Yaskawa servo systems; confirm drive series and feedback interface before installation.”
That stays truthful and reduces returns.
Mechanical fit
Most failures in the field are not “mysterious electronics gremlins.” They’re alignment, coupling stress, or mounting mistakes. Practical best practices:
-
Use a coupling suited to your misalignment tolerance.
-
Avoid axial load beyond the motor’s bearing design.
-
Ensure rigid mounting to prevent resonance during aggressive acceleration.
Commissioning and tuning
Servo systems often need parameter setup and tuning to match load inertia, stiffness, and response goals. Even if your customer is experienced, it’s worth stating plainly:
-
“Performance depends on correct tuning and load matching.”
Listing-Ready Feature Summary (No fluff, no icons)
| Feature | Benefit in real use |
|---|---|
| 1.3 kW class servo motor (family reference) | Suitable for medium-duty axes needing fast, controlled motion |
| Designed for servo closed-loop applications | Accurate positioning, stable torque, repeatable motion quality |
| Common in robot-axis contexts (YR1* listing) | Practical for maintenance spares and robot service inventories |
| Net weight 12 kg (YR1D vendor listing) | Helps buyers plan handling, mounting, and shipping expectations |
Closing Positioning (Google-friendly, human-readable)
The YASKAWA SGMRV-13ANA-YR1D is best described as a robust AC servo motor for precision industrial motion, commonly aligned with Yaskawa’s servo ecosystems and seen in robot-axis spare part contexts. The key to a correct purchase is not just the base model code, but confirming the exact suffix/options, the matched servo drive, and the mechanical interface so the motor behaves like a servo motor—not an expensive paperweight that “sort of fits.”
