Drive the base
The AC motor converts drive current into torque, and the installed pinion transfers that torque to the axis-1 reduction gear that rotates the robot frame.

01
Product Introduction
ABB 3HAC043166-004 is a Type C rotational AC motor with pinion for axis 1 of applicable ABB IRB 4600 robots. It produces the controlled rotation that enters the base reduction gear and turns the robot frame under commands from the IRC5 drive system.
Three coordinated paths meet at ABB 3HAC043166-004: motor power produces torque, brake control holds or releases the vertical robot structure, and resolver feedback returns shaft position. The installed pinion transfers that torque into the axis-1 gear, so electrical and mechanical commissioning cannot be separated.
The ABB Orange Type C execution of ABB 3HAC043166-004 is verified from the robot serial and spare-parts record. Before removal the frame is secured, connectors are labelled and drive energy is isolated; after installation the axis is calibrated and tested for direction, brake action and smooth base rotation.

Product Functions
ABB 3HAC043166-004 performs the three functions required to drive, hold and measure the IRB 4600 base axis.
Hold the structure
The motor brake prevents uncommanded axis movement when drive torque is removed. Safe service depends on supporting the frame before the brake or motor is disconnected.
Report shaft position
Resolver feedback sends motor position to IRC5. The controller combines that signal with the configured gear relationship to regulate axis-1 movement and identify position deviation.
04
Diagnostics and Protection
Checks on ABB 3HAC043166-004 distinguish a power, brake, feedback or mechanical-drive problem before parts are replaced.
Separate electrical paths
Measure and inspect motor, brake and resolver circuits as different functions. A released brake does not prove that the motor phase or resolver path is correct.
Observe controlled motion
Use low-speed manual movement to compare current, sound, direction and displayed position. Abnormal behavior under reversal can expose pinion, gear or mounting issues not visible at standstill.
Protect the restored assembly
Secure cables, covers and seals so base rotation does not load the connectors. Complete calibration and brake checks before restoring automatic speed or payload operation.

Frequently Asked Questions
How should a technician keep the frame safe during motor removal for ABB 3HAC043166-004?
For ABB 3HAC043166-004, support axis 1 and verify isolation before disconnecting the brake or 3HAC043166-004.
What should be checked when a team needs to distinguish a brake fault from a drive fault for ABB 3HAC043166-004?
For ABB 3HAC043166-004, check brake release, motor power and resolver feedback as separate paths while the frame remains supported.
Why might a site need to confirm Type C compatibility for ABB 3HAC043166-004?
For ABB 3HAC043166-004, match 3HAC043166-004 to the IRB 4600 serial and installed axis-1 spare-parts record.
Which checks help a customer prevent pinion damage for ABB 3HAC043166-004?
For ABB 3HAC043166-004, align and seat the motor without using fasteners to force the pinion into the gear.
