Yaskawa SGM7G-44APK-YR11 AC Servo Motor – Sigma-7 Series Critical Spare Part

Technical Specifications

Solving the Critical Spare Parts Challenge

The Yaskawa Sigma-7 platform is deployed across semiconductor fabrication, automotive body welding, precision machining, and packaging lines worldwide. The SGM7G-44APK-YR11 — rated at 4.4 kW with a 23-bit absolute encoder — is a mid-to-high torque unit commonly found in multi-axis gantry systems and robotic welding positioners. Its absolute encoder eliminates the need for homing routines after power loss, which is precisely why facilities select it for continuous-duty applications where restart time is a direct cost factor.

Condition & Reliability Assurance

Every unit shipped by DriveKNMS passes a structured 5-step inspection protocol before dispatch:

• Step 1 – Visual and Mechanical Inspection: Shaft runout check, bearing play assessment, encoder housing integrity, and connector pin inspection for corrosion or mechanical damage.
• Step 2 – Encoder Verification: Absolute encoder battery circuit check (where applicable) and signal integrity confirmation. Firmware version is recorded and documented.
• Step 3 – Winding Resistance and Insulation Test: Phase-to-phase resistance balance and insulation resistance measurement to screen for winding degradation.
• Step 4 – Capacitor and Electronics Screening: For units with integrated electronics, electrolytic capacitor condition is assessed for signs of aging or leakage.
• Step 5 – Functional Run Test: Where test bench infrastructure permits, the motor is run under load to confirm smooth operation and encoder feedback accuracy.

Condition grade and test results are documented and provided with each shipment on request.

Frequently Asked Questions

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Q: How do I confirm compatibility with my existing SERVOPACK?
A: Provide your SERVOPACK model number (SGDV-XXXXX or SGD7S-XXXXX) when you contact us. We will confirm the motor-drive pairing before dispatch review.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.
