ABB MTD5003HAC038210-002 / 3HAC034644-003 / 3HAC052991-005 – Axis 1 Servo Motor incl Pinion | IRB 6600 / IRB 6650 Platform
Engineering Background
The ABB IRB 6600 and IRB 6650 series are heavy-payload industrial robots widely deployed in automotive body-in-white welding, press-tending, and large-part material handling. Axis 1 (base rotation) carries the full dynamic load of the robot arm and payload, demanding a servo motor assembly with exceptional torque density, thermal stability, and mechanical precision. The MTD5003HAC038210-002 motor assembly — cross-referenced as 3HAC034644-003 and 3HAC052991-005 — is the OEM-specified drive unit for this axis.
Product Positioning
This listing supplies the complete Axis 1 motor assembly including the integrated pinion gear, ready for direct installation. It is sourced through verified industrial channels and is suitable for both emergency breakdown replacement and planned preventive maintenance programs. Konmask.com maintains stock to support short lead-time procurement requirements common in production-critical environments.

Engineering Advantages
- OEM Dimensional Accuracy: Pinion gear machined to ABB tolerance stack-up; no shimming or re-meshing required on installation
- Thermal Management: Motor windings rated for continuous duty in high-ambient foundry and press environments
- Encoder Integrity: Factory-calibrated resolver eliminates the need for axis mastering recalibration in most replacement scenarios
- Drop-in Compatibility: Matches OEM connector pinout and cable routing for IRB 6600/6650 Axis 1 without harness modification
- Reduced Downtime: Complete assembly (motor + pinion) ships as one unit — no sub-assembly required on the production floor
System Architecture & Signal Flow
In the IRB 6600/6650 control architecture, the IRC5 controller issues torque commands via the drive module to the Axis 1 servo motor. The motor’s resolver feeds position and velocity feedback through the Measurement Board (DSQC) back to the IRC5 motion controller. The integrated pinion transmits motor torque to the main gearbox ring gear, driving base rotation. Replacing this assembly restores the full closed-loop servo chain without requiring gearbox disassembly.

Technical FAQ
Q: Are all three part numbers (MTD5003HAC038210-002, 3HAC034644-003, 3HAC052991-005) the same physical part?
A: Yes. These are ABB’s internal cross-reference numbers representing the same Axis 1 motor assembly across different catalog revisions and robot variants within the IRB 6600/6650 family.
Q: Does this motor require axis mastering after installation?
A: In most cases, axis mastering (calibration) is required after any motor replacement on ABB robots. We recommend following ABB’s standard mastering procedure using the FlexPendant after installation.
Q: Is this compatible with both S4C+ and IRC5 controllers?
A: The motor assembly is mechanically identical across controller generations. Electrical compatibility depends on the drive module version — please confirm your controller type at inquiry.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For surplus or sourced units, lead time is typically 5–15 business days. Contact us for real-time availability.
Q: Can you provide a warranty?
A: New OEM units carry the standard ABB warranty. Surplus-new units are covered by Konmask’s 90-day functional warranty against manufacturing defects.
