ABB 3HAC046186-004 Motor Incl Pinion – Obsolete IRB6700 Spare Part

When a motor assembly fails on an ABB IRB6700 robot, the operational clock starts ticking immediately. A single axis motor failure halts the entire robot cell. For automotive body shops, foundries, and heavy-part handling lines running IRB6700 units, an unplanned stoppage can cascade into production losses measured in tens of thousands of dollars per shift. The path of least resistance — a full robot replacement or a forced migration to a newer ABB generation — carries capital expenditure that routinely exceeds USD 150,000 per unit, plus re-integration engineering, re-programming, and re-certification costs that can double that figure.

DriveKNMS holds RFQ-reviewed sourcing status of the ABB 3HAC046186-004 / 3HAC045146-010 / 3HAC048334-002 Motor Incl Pinion assembly. This is not a commodity component. It is a precision-matched servo motor with integrated pinion gear, factory-calibrated for the IRB6700 axis drive train. Sourcing it through standard distribution channels is no longer reliable. Protecting your existing robot asset with a confirmed spare is the lowest-cost insurance available to your maintenance team.

Technical Specifications

Note: Electrical parameters (voltage rating, encoder resolution, torque specifications) are axis-position dependent on the IRB6700 configuration. Confirmed specifications are provided upon request with your robot serial number and axis designation.

Solving the Discontinued Hardware Crisis

The 3HAC046186-004 motor assembly is not interchangeable with components from newer ABB generations. The pinion gear geometry, encoder protocol, and mechanical mounting interface are specific to the IRB6700 drive train. Substituting an incompatible motor risks axis calibration failure, gearbox damage, and in worst cases, a collision event that writes off the entire robot arm.

Facilities that have invested in ABB IRC5 controller infrastructure paired with IRB6700 arms have a clear economic incentive to maintain these assets. The IRC5 controller, the application software, the tooling, the safety fencing, and the production cell layout all represent sunk costs that are recovered only through continued operation. A confirmed spare motor on the shelf converts a potential six-figure forced upgrade into a planned maintenance event measured in hours.

How to extend your IRB6700 asset life by 5–10 years at low cost:

Condition & Reliability Assurance

Sourcing obsolete servo motor assemblies from the secondary market carries legitimate risk. DriveKNMS applies a structured 5-step quality process to every unit before it is offered for sale.

Condition grade (New / Refurbished / Tested Used) is disclosed explicitly in the quotation. No unit is shipped without a condition declaration.

Key Features for System Maintenance

How do I confirm the unit is new or quality-refurbished?
Condition grade is declared in the quotation document and on the shipping label. New-in-box units include original ABB packaging where available. Refurbished units include a DriveKNMS inspection report. We do not sell units of unknown condition without explicit disclosure.

Should I purchase more than one unit?
For facilities operating two or more IRB6700 robots, holding a minimum of two motor assemblies covering your highest-cycle axes is a defensible maintenance position. Current secondary market availability of this part number is limited. Procurement decisions made today will not be available at the same price or availability level in 12–24 months.
