Compact torque delivery
The motor and pinion supply the high-speed input to the axis-6 gearbox. The gear then reduces speed and increases torque at the tool-facing wrist output.

01
Model Information
ABB 3HAC043457-003 is a Type A axis-6 motor with pinion for applicable ABB IRB 6700 robots. Installed in the wrist drive, it converts IRC5 drive current into the rotational input used by the terminal wrist gearbox and carries resolver feedback back to the controller.
The assembly includes the motor-and-pinion path together with its connection box, cover and sealing parts. On ABB 3HAC043457-003, power, brake and feedback connections are routed through the wrist structure, while the pinion and gearbox convert motor rotation into axis-6 movement for the configured IRB 6700 reach variant.
Type A and later Type B executions are not treated as interchangeable without the applicable conversion record. Selection of ABB 3HAC043457-003 therefore uses the robot serial date, axis-6 spare-parts list and Graphite White execution; commissioning checks seals, cable support, brake action and calibration.

Performance Characteristics
ABB 3HAC043457-003 controls how quickly and accurately the terminal wrist can rotate while carrying the configured tool and wrist load.
Dynamic reversals
Axis 6 often changes direction during orientation moves. Correct pinion engagement, brake release and resolver feedback allow IRC5 to settle those moves without treating mechanical play as electrical error.
Sealed wrist execution
Connection box, cover and O-rings protect the electrical and mechanical path inside the wrist. Their condition matters because contamination or cable strain can affect the same assembly as the motor.
04
System Integration
ABB 3HAC043457-003 is integrated by robot execution, wrist mechanics, controller drive assignment and the Type A service record.
Execution match
The IRB 6700 serial and production date establish whether the installed wrist is Type A or a later execution. A matching appearance is not sufficient evidence of interchangeability.
Drive and feedback
IRC5 sends motor and brake power to the assigned axis channel and receives resolver position from the same assembly. Connector identity must remain aligned with that controller assignment.
Mechanical output
The pinion transfers motor rotation into the axis-6 gearbox while covers and supports guide the cable route. Reassembly is complete only when both motion and the protected service geometry are restored.
