ABB 3HAC057549-003 Rotational AC Motor with Pinion – IRB 6650 Industrial Robot Series
When a rotational axis motor fails on an ABB IRB 6650 robot, the entire production line stops. In high-throughput automotive welding, heavy-duty material handling, and precision foundry operations, even a single hour of unplanned downtime can cost tens of thousands of dollars. The axis drive motor is not a peripheral component — it is the mechanical heart of every articulated movement the robot makes. Without a verified, OEM-compatible replacement like the ABB 3HAC057549-003, restoring full robot functionality is impossible.
The 3HAC057549-003 is ABB’s factory-designated rotational AC servo motor with integrated pinion gear, engineered specifically for the IRB 6650 series — one of ABB’s most widely deployed heavy-payload industrial robots, rated for payloads up to 235 kg and reach up to 3.9 m. This motor assembly is a precision-matched drive component that interfaces directly with the robot’s axis gearbox, ensuring torque transmission accuracy, positional repeatability, and long-term mechanical integrity. It is a critical spare part stocked by maintenance engineers in automotive OEMs, tier-1 suppliers, and industrial automation integrators worldwide.
