ABB 3HAC021729-001 Motor with Pinion – IRB4400 Industrial Robot Series
When a servo motor fails on an ABB IRB4400 robot arm, the entire production line grinds to a halt. Automotive welding cells, material handling systems, and precision assembly stations all depend on the continuous, accurate torque delivery of the axis drive motor. Without a reliable replacement like the ABB 3HAC021729-001, unplanned downtime can cost manufacturers thousands of dollars per hour — making fast access to the correct, verified spare part absolutely critical.
The 3HAC021729-001 is the OEM-specified motor with integrated pinion gear for the ABB IRB4400 robot series — a 6-axis industrial robot platform widely deployed across automotive, foundry, and heavy-duty manufacturing environments. This motor assembly is also cross-referenced under part numbers 3HAC17336-1, 3HAC17394-1, and 3HAC021728-001, covering multiple revision levels of the same axis drive unit. As a core motion component within ABB’s S4C+ and IRC5 controller ecosystems, this part maintains its position as one of the most sought-after replacement units in the global industrial robot spare parts market.
