ABB 3HAC055699-003 Robot Motor Unit – IRB6700 / IRB260 Axes 1-3 Critical Spare Part

Technical Specifications

Note: Electrical parameters (voltage, current ratings, encoder specifications) vary by robot serial number and software version. Contact us with your robot serial number for full compatibility confirmation before ordering.

Solving the Critical Spare Hardware Problem

The ABB IRB6700 series is a backbone of heavy-payload automation in automotive, foundry, and general manufacturing environments. These robots are engineered for 20+ year service lives — but the supply chain for their internal assemblies does not always match that horizon. The 3HAC055699-003 motor unit is a precision assembly that cannot be substituted with generic components. Its encoder interface, mechanical mounting geometry, and firmware handshake with the IRC5 controller are specific to this platform.

Condition & Reliability Assurance

Every 3HAC055699-003 unit processed through DriveKNMS undergoes a structured 5-step inspection protocol before it is offered for sale:

• Step 1 – Visual and Mechanical Inspection: Housing integrity, connector condition, and mounting surface assessment. Units with physical damage to the encoder housing or motor shaft are rejected at this stage.
• Step 2 – Electrolytic Capacitor Assessment: Internal capacitors in aging motor drive assemblies are a primary failure mode. Units are evaluated for capacitor bulge, leakage, and ESR deviation. Where capacitor degradation is confirmed, the unit is not offered as a serviceable spare.
• Step 3 – Connector and Pin Corrosion Check: All signal and power connectors are inspected under magnification. Oxidized or corroded pins are documented. Units with compromised connector integrity are not cleared for sale.
• Step 4 – Firmware and Label Verification: The unit's hardware revision label is cross-checked against known compatible firmware versions for the IRC5 controller. Mismatched revisions are flagged and disclosed.
• Step 5 – Functional Bench Test (where applicable): Units that pass steps 1–4 are bench-tested for basic electrical continuity and encoder signal output where test equipment permits.

Key Features for System Maintenance

Q: Can this unit be used in an IRB6700 variant other than the -150 payload version?
A: Compatibility across IRB6700 payload variants depends on the specific robot serial number and mechanical revision. Contact us with your robot's serial number and we will confirm compatibility before processing your order.
