ABB 3HAB3125-1 / 3HAC11865-1 / 3HAC11854-1 Servo Motor Unit – IRB2400 & IRB4400 Robot Series
When a servo motor unit fails on an ABB industrial robot, the entire production line comes to a halt. Unplanned downtime in automotive welding, material handling, or precision assembly can cost thousands of dollars per hour. The ABB Motor Unit — covering part numbers 3HAB3125-1, 3HAC11865-1, 3HAC11854-1, 3HAC10544-1, 3HAC10602-1, E3HAC10603-1, and 3HAC2847-1 — is the critical drive component that keeps your robot arm moving with precision and reliability. Without it, your IRB2400 or IRB4400 robot is simply a stationary arm.
These motor units are purpose-engineered for ABB’s flagship IRB2400 and IRB4400 industrial robot platforms — two of the most widely deployed 6-axis robot families in global manufacturing. The IRB2400 is the world’s best-selling industrial robot for arc welding and material handling, while the IRB4400 is trusted for heavy-duty spot welding and press tending. These motor units serve axis drives across both platforms, making them among the highest-demand spare parts in the ABB robotics ecosystem worldwide.
