Description
Product Introduction & Engineering Value
The Yaskawa SGMAV-08ADA61 is a compact, low-inertia AC servo motor designed for applications requiring fast acceleration, accurate positioning, and repeatable motion cycles. It delivers 750 W output with a rated speed of 3000 RPM and supports high-speed operation up to 6000 RPM depending on system configuration.
For maintenance teams supporting existing Yaskawa motion platforms, this SGMAV series motor remains a practical replacement option when the mechanical axis, amplifier, and control architecture are still serviceable. Correct encoder matching and motor parameter verification are essential during changeout.

Field Application & The “Trench” Experience
A PCB assembly machine at an electronics manufacturing plant began losing placement accuracy after years of continuous operation. The machine controller reported intermittent position deviation alarms on one high-speed feeder axis. Initial troubleshooting focused on the servo amplifier, but encoder feedback analysis showed the motor assembly had developed performance issues.
The maintenance team replaced the failed motor with a verified Yaskawa SGMAV-08ADA61, restored the original servo parameters, confirmed encoder feedback operation, and completed axis tuning. The production line returned to normal operation without replacing the motion controller or mechanical assembly.
Typical application scenarios include:
- High-speed PCB placement and drilling equipment
- Semiconductor wafer handling and transfer mechanisms
- Precision material feeding systems in automated production lines
- Small robotic positioning axes requiring low-inertia response

Transparency SOP: QA & Testing
Every New Surplus or Refurbished SGMAV-08ADA61 motor should be evaluated through a controlled inspection process:
Incoming Inspection
- Verify model marking: SGMAV-08ADA61.
- Check shaft condition, flange surface, connectors, and housing.
- Inspect for oil contamination, impact marks, or corrosion.
Electrical Verification
- Measure winding resistance balance.
- Confirm insulation condition.
- Check encoder connector integrity.
Operational Testing
- Run motor with compatible servo amplifier where available.
- Verify rotation behavior.
- Confirm feedback response and abnormal noise conditions.
Final Release
- Record inspection results.
- Protect shaft and connectors for shipment.
- Include traceability information for customer receiving inspection.
The Veteran’s Tech Trap Guide
⚠️ Do Not Match Only the Wattage
A 750 W servo motor is not automatically a replacement. Engineers must confirm encoder type, flange dimensions, shaft configuration, and amplifier compatibility.
PRO TIP:
Always compare the complete Yaskawa model code, not just the SGMAV prefix.
⚠️ Encoder Compatibility Can Stop a Startup
The SGMAV-08ADA61 uses a high-resolution encoder system. Incorrect feedback configuration can cause encoder alarms immediately after power-up.
⚠️ Mechanical Alignment Matters
A servo motor may pass electrical checks but still create vibration if the coupling, shaft alignment, or load inertia is incorrect.
Dynamic FAQ
Q1: What is the Yaskawa SGMAV-08ADA61 used for?
The SGMAV-08ADA61 is a Yaskawa AC servo motor designed for precision motion applications such as semiconductor equipment, assembly machinery, robots, and automated handling systems.
Q2: What are the main specifications of the SGMAV-08ADA61?
