ABB 3HAC039109-002 – AC Servo Motor with Encoder | IRB4600 / IRB6700 Platform
Engineering Background: The ABB 3HAC039109-002 is an OEM AC servo motor assembly designed for ABB’s sixth-generation industrial robot platforms — the IRB4600 and IRB6700 series. These robots are deployed globally in automotive body-in-white welding, heavy-duty material handling, and precision assembly lines where axis-level torque accuracy and thermal stability are non-negotiable.
Product Positioning: As a direct OEM replacement for the rotary AC motor (including encoder/resolver), this unit restores full factory-spec performance to axis drives without requiring recalibration of the robot controller. Procurement engineers sourcing for planned maintenance windows or emergency downtime recovery will find this part stocked and ready to ship from Konmask.com.

Engineering Advantages
- OEM Dimensional Compliance: Direct bolt-on fit — no machining or adapter plates required
- Encoder Pre-Calibrated: Factory resolver offset retained; minimizes IRC5 controller re-mastering time
- Thermal Class H Insulation: Rated for continuous duty in high-ambient industrial environments
- Low Cogging Torque: Smooth velocity control at low RPM for precision path applications
- Sealed Bearing Assembly: Extended service intervals in contaminated environments
- Cross-Compatible SKU: Single part number covers multiple IRB4600 and IRB6700 axis positions
System Architecture & Signal Flow
The 3HAC039109-002 interfaces directly with the ABB IRC5 drive module via the standard SMB (Serial Measurement Board) bus. The integrated encoder transmits absolute position data to the axis computer, enabling the IRC5 controller to maintain closed-loop torque and velocity control. Power is supplied through the drive unit’s motor output stage; no external encoder power supply is required. Signal integrity is maintained by the OEM connector and shielded cable harness (ordered separately as 3HAC031683-001 or equivalent).

Technical FAQ
Q: Is 3HAC039109-002 compatible with both IRB4600 and IRB6700?
A: Yes. This motor assembly is cross-listed for multiple axis positions on both platforms. Confirm your robot serial number and axis position when submitting your RFQ for final verification.
Q: Does replacing this motor require robot re-mastering?
A: Typically yes — ABB recommends axis re-mastering after any motor replacement. However, if the resolver offset is retained and the SMB battery is intact, re-mastering time is minimal using the IRC5 FlexPendant calibration routine.
Q: What is the warranty on this part?
A: New OEM units carry the standard ABB warranty. Refurbished units carry a 90-day Konmask functional warranty. Contact us for details.
Q: Can you supply the mating cable harness?
A: Yes. We stock associated cable assemblies and SMB units. Specify your robot variant when ordering.
