ABB IRB7600-3/HAC025819-001 AC Servo Motor – IRB6650S Series Drive Unit
When a critical AC servo motor fails on an ABB IRB7600 or IRB6650S industrial robot, the entire production line stops. In automotive body shops, foundries, and heavy-payload assembly cells, even one hour of unplanned downtime can cost tens of thousands of dollars. The ABB servo motor is not a commodity component — it is the precision heart of the robot’s axis drive system, and no generic substitute can replicate its encoder resolution, thermal management, or dynamic torque response.
The HAC025819-001 servo motor is the OEM-specified drive unit for the ABB IRB7600-3 heavy-payload robot, while the HAC062348-004, HAC062346-004, and HAC062345-004 variants serve the IRB6650S/6.3, IRB6650S/4.3, and IRB6650S/3 configurations respectively. These motors represent ABB’s highest-tier axis drive technology, engineered for robots operating at payloads of 3–6.3 tonnes in the most demanding industrial environments globally.

Frequently Asked Questions
Q: Can I use HAC062348-004 on an IRB6650S/4.3 robot?
A: No. HAC062348-004 is specified for the IRB6650S/6.3 variant. The IRB6650S/4.3 uses HAC062346-004. Using an incorrect motor part number may cause axis calibration errors or drive faults. Always verify against your robot’s spare parts manual.
Q: Do these motors require re-calibration after replacement?
A: If the absolute encoder battery is maintained and the SMB board is not replaced simultaneously, axis calibration data is typically retained. However, ABB recommends performing a fine calibration check after any servo motor replacement.
Q: Are these OEM parts or aftermarket?
A: We supply both genuine ABB OEM parts and high-quality tested refurbished units. The condition (new/refurbished) will be clearly stated in your quotation. We do not supply uncertified aftermarket motors for safety-critical robot axes.
Q: What is the typical lead time for HAC025819-001?
A: Lead time depends on current stock. Please submit an inquiry for a real-time availability check. Urgent requirements can often be fulfilled within 5–7 business days via express sourcing.
Q: Can you supply the complete motor replacement kit including cables and connectors?
A: Yes. We can bundle the servo motor with the appropriate encoder cable, power cable, and connector kit for your specific IRB7600 or IRB6650S axis. Please specify this requirement in your inquiry.
