Overview Manuals Specifications Motor Matching Replacement Workflow Commissioning Check

Features:

  • Axis-specific configuration: ABB documents this assembly for IRB 4400 axis 2.
  • Integrated drive gear: The motor and drive gear form one service unit and the pinion is included.
  • Elmo connection set: The official manual separates this Elmo version from incompatible Yaskawa connections.
ABB 3HAC5954-1 gives maintenance teams the official Elmo motor identity for the IRB 4400 axis 2 position.

The assembly is serviced as a motor-and-drive-gear unit, so removal and installation must follow the robot manual rather than a generic motor procedure.

A correct repair scope includes safe arm support, brake release, motor positioning, oil restoration, reconnection, and recalibration.

Availability of 3HAC5954-1 is subject to Apter Power's current inventory and sourcing confirmation.

  • Match the complete robot and motor nameplate before procurement.
  • Confirm axis 2; the axis 3 motor has a different ordering identity.
  • Use the documented Elmo configuration because Yaskawa connections are not compatible.
  • Support the IRB 4400 arm and isolate electrical, hydraulic, and pneumatic energy.
  • Apply the documented 24 V brake-release method only after the arm is secured.
  • Restore sealing work and axis oil as specified during reassembly.
  • Reconnect the motor from the robot circuit documentation rather than cable appearance.
  • Complete motor adjustment and robot recalibration after the mechanical work.
  • Run the prescribed first test cycle before returning the axis to production.
Description

Within the IRB 4400 arm, 3HAC5954-1 is the ABB Orange Elmo motor unit assigned to axis 2. The official service manual treats its motor, drive gear, and included pinion as one assembly.

ABB distinguishes 3HAC5954-1 from the separately documented Yaskawa motor variant because their connections are not compatible. That configuration boundary is more important than the similar mechanical location.

A purchase decision for 3HAC5954-1 should be based on the complete nameplate and confirmed axis position. The repair scope then needs safe arm support, brake release, oil restoration, reconnection, and robot recalibration.

Technical notes
ABB 3HAC5954-1 is the Elmo axis 2 unit; ABB states that Elmo and Yaskawa connections are not compatible. Isolate all utilities, secure the arm, restore oil and connections, then recalibrate before returning the IRB 4400 to service.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
3HAC5954-1 is ready for refitting only after which IRB 4400 axis 2 brake-release connection has been prepared?
ABB directs the 24 VDC brake-release supply to connector R3.MP2, with +24 V on pin 7 and 0 V on pin 8.
Which motor-label orientation must the technician record before removing 3HAC5954-1 from the gearbox?
Record the motor-label orientation before loosening the unit. The replacement motor must return with the label in the same position.
How should the sealing surfaces be prepared when ABB 3HAC5954-1 is installed after motor removal?
Remove paint and lubricant from the mating surfaces, inspect them for damage, fit the specified O-ring, and apply Loctite 574 to the motor flange.
What installation condition protects the pinion while ABB 3HAC5954-1 is being seated?
Do not force the motor into the gearbox. Seat the flange with the upper and lower screws while retaining the required backlash, then complete the motor adjustment before final fastening.
Which fastening evidence should close the mechanical work on an ABB 3HAC5954-1 axis 2 assembly?
After motor adjustment, the axis 2 procedure uses two M10x70 and two M10x30 screws, tightened to 60 Nm. Record that result with the service work.
What documents should a maintenance contractor request before scoping an ABB 3HAC5954-1 motor change?
Request the IRB 4400 circuit diagram, the axis-specific replacement procedure, the calibration instructions, and the required-tool list before planning labor or commissioning.
