ABB 3HAC14673-9 – Servo Motor with Pinion | IRB6640 / IRB6600 / IRB6650 / IRB6650S Platform
Engineering Background
The ABB IRB6640 series represents ABB Robotics’ flagship heavy-payload articulated robot platform, widely deployed in automotive body-in-white welding, press-tending, and material handling lines. Axis drive integrity is mission-critical: a degraded motor-pinion assembly directly impacts path accuracy, cycle repeatability, and TCP consistency. Part number 3HAC14673-9 is the OEM-specified servo motor with integrated pinion for this platform, with cross-compatible variants 3HAC14750-2 and 3HAC15885-2 covering extended IRB6600/6650/6650S configurations.
Product Positioning
Konmask.com supplies this assembly as a verified OEM-grade replacement targeting maintenance engineers, robot integrators, and MRO procurement teams who require traceable, specification-accurate parts with minimal lead time. This is not a generic aftermarket substitute — sourcing integrity and part authenticity are our primary quality commitments.

Engineering Advantages
- OEM Part Integrity: Direct ABB part number — no reverse-engineered substitutes, ensuring full compatibility with ABB IRC5 / S4C+ controller firmware
- Pre-Aligned Pinion: Factory-assembled pinion eliminates field alignment errors that cause premature gear wear and axis backlash
- Drop-In Replacement: Plug-and-play fit for IRB6640/6600/6650/6650S axis drive bays — no mechanical modification required
- Reduced Downtime: Stocked for immediate dispatch, minimizing unplanned production stoppages
- Cross-Model Coverage: Single procurement covers three P/N variants across the IRB6000 platform family
System Architecture & Signal Flow
In the ABB IRB6640 drive architecture, each axis servo motor receives motion commands from the IRC5 Drive Module via the Axis Computer (DSQC 668 / DSQC 400 series). The 3HAC14673-9 motor converts electrical torque commands into mechanical rotation, transmitted through the integrated pinion to the axis gearbox. Encoder feedback is returned to the Axis Computer for closed-loop position control. A failed or worn motor-pinion assembly manifests as axis following errors (ERR_PATH_STOP), abnormal joint noise, or TCP drift — all of which this replacement directly resolves.

Technical FAQ
Q: Is 3HAC14673-9 interchangeable with 3HAC14750-2 and 3HAC15885-2?
A: These three part numbers cover the same motor-pinion assembly across different IRB6000 platform variants. Confirm your robot model and axis specification before ordering; our technical team can assist with cross-reference validation.
Q: Which axis does this motor serve on the IRB6640?
A: Please provide your robot’s service manual axis reference or contact us with your robot serial number for axis-specific confirmation.
Q: Can this be used with the IRC5 Compact controller?
A: Yes, provided the drive module and axis computer firmware are compatible with the IRB6640/6600 series. Consult your ABB system documentation or contact Konmask technical support.
Q: Do you offer warranty on this part?
A: Yes. New OEM units carry the standard ABB warranty. Refurbished units carry a Konmask 90-day functional warranty. Details provided at time of purchase.
