ABB 3HAC055448-003 Motor Incl Pinion – Axis Servo Drive Unit | IRB 6700 Platform
Engineering Background
The ABB IRB 6700 is ABB Robotics’ flagship heavy-payload articulated robot series, engineered for demanding automotive, foundry, and heavy manufacturing environments. Each axis is driven by a precision servo motor assembly that integrates the motor body and pinion gear as a single matched unit—ensuring backlash-free torque transmission and repeatable positioning accuracy over millions of cycles.
Product Positioning
Part number 3HAC055448-003 (cross-reference: 3HAC051407-003, 3HAC055700-004) is the OEM-specified Motor Incl Pinion assembly for the IRB 6700 axis drive train. Sourced from verified ABB-authorized supply channels, this unit is a direct drop-in replacement requiring no mechanical modification, calibration offset adjustment, or firmware re-parameterization beyond standard ABB commissioning procedures.

Proven Application Environments
- Automotive Body-in-White – High-cycle spot welding and material handling on IRB 6700 cells
- Foundry & Die Casting – Extreme-temperature axis replacement in IP67-rated robot configurations
- Heavy Palletizing – Payload-intensive axis drives requiring sustained torque output
- Machine Tending – CNC loading/unloading with precision repeatability demands
- Maintenance & Overhaul – Scheduled preventive replacement per ABB service intervals
Engineering Advantages
- OEM-Matched Pinion: Factory-assembled pinion eliminates field-matching errors and gear mesh inconsistencies common with aftermarket assemblies.
- Direct Drop-In Compatibility: Identical mechanical envelope and electrical interface to original ABB specification—no adapter plates or wiring modifications required.
- Verified Traceability: Each unit carries ABB part marking and batch traceability, supporting ISO 9001 maintenance documentation requirements.
- Reduced Downtime: Pre-assembled unit cuts mean-time-to-repair (MTTR) versus sourcing motor and pinion separately.
- Cross-Reference Coverage: Covers three ABB part numbers (3HAC055448-003 / 3HAC051407-003 / 3HAC055700-004), simplifying procurement across mixed IRB 6700 fleets.
System Architecture & Signal Flow
In the IRB 6700 drive architecture, the axis servo motor receives torque commands from the Drive Unit via the Axis Computer (DSQC), which interprets motion profiles from the IRC5/OmniCore controller. The Motor Incl Pinion assembly converts electrical drive signals into mechanical rotation, transmitted through the integrated pinion into the axis gearbox. The resolver or encoder feedback loop closes the position control circuit back to the drive unit, ensuring sub-millimeter TCP repeatability.
Replacing this assembly with a correctly matched OEM unit (3HAC055448-003) preserves the integrity of this closed-loop chain without requiring resolver offset re-calibration beyond ABB’s standard fine-calibration procedure.
Sourcing & Quality Verification
- All units inspected against ABB part marking, label integrity, and connector condition prior to shipment.
- Stored in ESD-safe, climate-controlled warehouse to preserve motor winding and encoder integrity.
- Batch documentation and CoC (Certificate of Conformance) available upon request for MRO and OEM procurement teams.
- Anti-counterfeit verification: holographic ABB labels and serialized packaging checked at intake.

Technical FAQ
Q: Are 3HAC055448-003, 3HAC051407-003, and 3HAC055700-004 fully interchangeable?
A: These part numbers represent the same functional assembly across different ABB revision levels. Confirm your robot’s serial number and axis designation with our technical team before ordering if you are unsure.
Q: Does this motor require resolver calibration after installation?
A: Yes. ABB standard procedure requires fine calibration (revolution counter update and axis calibration) after any motor replacement on the IRB 6700. This is performed via RobotStudio or the FlexPendant.
Q: Can this unit be used on IRB 6700-150/3.2 and IRB 6700-200/2.6 variants?
A: Compatibility depends on the specific axis. Please provide your robot model, payload variant, and axis number for confirmation.
Q: What is the lead time for in-stock units?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 2–4 weeks. Contact us for real-time availability.
Q: Do you provide a warranty?
A: Yes, 12 months from shipment date covering manufacturing defects. Does not cover damage from improper installation or electrical faults external to the motor.
