ABB 3HAC021724-001 / 3HAC021725-001 IRB 4400 Motor-with-Pinion Assemblies
01
Equipment Description
ABB 3HAC021724-001 and ABB 3HAC021725-001 are Yaskawa motor-with-pinion assemblies used in the IRB 4400 family. The parts list distinguishes their robot variants and axis assignments instead of treating them as one motor record.
ABB 3HAC021724-001 is associated with axis 1 on the IRB 4400 L10/45/60 execution. ABB 3HAC021725-001 is used for axis 1 on the IRB 4400 L/30 execution and appears in the relevant axes 2–3 motor context, so the installed robot and axis must be checked together.
During replacement, ABB 3HAC021724-001 or ABB 3HAC021725-001 must be protected from joint movement, connector mix-up and pinion contamination. A controlled brake, feedback and mastering check completes the axis-specific installation.

Installation Highlights
Installation Highlights for the exact ABB records
ABB 3HAC021724-001 and ABB 3HAC021725-001 installation begins with the exact IRB 4400 variant and axis, because the motor-with-pinion records serve different mechanical positions.
Protect the pinion interface
Keep the motor pinion and gearbox opening clean, transfer seals and fasteners as specified and avoid forcing engagement.
Restore the axis record
Reconnect power, brake and feedback to the labeled path, then document any mastering action required after installation.

Product Functions
Model-specific service context
3HAC021724-001 / 3HAC021725-001
ABB 3HAC021724-001 and ABB 3HAC021725-001 combine an AC motor and pinion so the controller drive path can apply torque to the assigned IRB 4400 joint.
Convert the drive command
The motor converts electrical drive output into controlled rotational torque for the selected joint.
Transmit through the pinion
The integrated pinion transfers motor torque into the matched mechanical transmission without a separate loose pinion selection.
Support controlled positioning
Brake and feedback connections let the controller hold, commutate and monitor the assigned axis after correct installation.
