The YASKAWA SGMRV-30ANA-YR11 is a mid-power AC servo motor designed for applications that need controlled torque, stable speed regulation, and accurate positioning under real industrial loads. Sitting in the 3.0 kW class with a 200 V input rating, it is commonly used on demanding axes such as medium-size conveyors, indexing tables, rotary cutters, winding systems, machine tool auxiliaries, and robotic external axes where a motor must accelerate confidently, hold torque smoothly, and repeat the same motion profile for millions of cycles.
What makes this motor practical in the field is not “mystery performance,” but a set of balanced characteristics: a mainstream rated speed (1500 rpm), meaningful continuous torque (18.5 N·m nominal), and enough peak capability (19.8 N·m short-term peak torque) to handle acceleration spikes and transient loads without immediately saturating the drive. In addition, published parameters such as rated current (22.7 A), peak current (62.3 A), maximum speed (4600 rpm), and moment of inertia (46 × 10⁻⁴ kg·m²) help engineers size drives, choose gear ratios, and tune motion loops with fewer surprises.
SGMRV motors are also widely seen in robot ecosystems and external-axis packages. In Yaskawa Motoman’s parts catalog, SGMRV-30ANA-YR11 appears as an “also known as” variant under a Sigma-5 related listing, which is a useful clue when you’re matching spares across naming conventions and internal part numbers.
The following specifications are taken from a published SGMRV technical data table and a common supplier listing for speed/voltage class.
Note: Technical data tables often include multiple “peak” concepts (short-term peak torque vs. maximum peak torque). For drive sizing, always align the definition used by your servo amplifier and motion profile.
A 3.0 kW servo motor like the SGMRV-30ANA-YR11 is typically selected when you are past the “small axis” stage. At this level, load inertia, friction, and duty cycle become the main villains. The motor must:
Deliver repeatable torque across the full cycle, not just during a short demonstration move.
Maintain stability during acceleration and deceleration, where current spikes happen.
Provide enough speed headroom (up to 4600 rpm max) to support gearing choices and dynamic tuning.
In practical terms, this motor is a strong candidate for axes where you want a single solution that can do both:
steady-state torque (conveying, winding tension, constant-speed rotating loads)
dynamic motion (indexing, oscillation, rapid point-to-point moves)
The published SGMRV table lists a 180 × 180 mm flange for the 3.0 kW size. That matters because retrofit jobs fail more often on bolt patterns and shaft/coupling geometry than on electrical compatibility.
A second practical point is logistics. In a Yaskawa Motoman spare-part listing associated with SGMRV-30ANA-YR11 naming, the packaged weight is listed as 44.015 lb, with packaging dimensions 11.8 × 16.2 × 8.8 inches. If you ship internationally, that packaging volume can push costs more than people expect, especially by air.
| Load behavior | Why SGMRV-30ANA-YR11 is a good fit | Typical examples |
|---|---|---|
| High inertia, moderate speed | Inertia rating and torque allow stable acceleration planning | Index tables, rotary drums, large rollers |
| Frequent accel/decel cycles | Current and torque headroom support transient demands | Cut-to-length, intermittent conveyors |
| Variable torque requirements | Solid nominal torque for continuous process load | Winding, tension control, mixing feeders |
| Gearbox-driven axis | Speed headroom supports ratio selection up to max speed | Rack-and-pinion, belt-driven gantry |
Servo motors do not live alone. For a reliable system, match the motor with a compatible servo amplifier and feedback configuration, then commission it with discipline.
Use the motor’s nominal current (22.7 A) and peak current (62.3 A) as hard constraints when selecting the servo drive capacity, regeneration handling, and cabinet thermal design. If your motion profile includes aggressive decel ramps, the regeneration path (braking resistor or regen unit) matters as much as motor torque.
A commissioning approach that usually works well in production environments:
| Step | What to check | Why it matters |
|---|---|---|
| Mechanical alignment | Coupling runout, bearing feel, mounting flatness | Reduces vibration and encoder errors |
| Drive parameterization | Correct motor selection, current limits, speed limits | Prevents overcurrent trips and instability |
| Initial tuning | Conservative gains first, then optimize | Avoids oscillation and overshoot |
| Thermal verification | Motor case temp and drive heat under worst duty | Confirms real-world sizing |
| Repeatability test | Run the same cycle 100+ times | Proves stability, not luck |
The YASKAWA SGMRV-30ANA-YR11 is a robust 3.0 kW, 200 V class AC servo motor with published performance figures including 18.5 N·m nominal torque, 1500 rpm rated speed, 22.7 A nominal current, and 4600 rpm max speed, making it well suited for medium-power industrial axes that demand repeatable motion and controlled torque under load. For spares and logistics planning, related parts listings also provide practical packaging data such as 44.015 lb packaged weight.
