More Information

Overview Manuals Axis Selection Pinion Matching Seal & Recovery Product Applications

Features:

  • Dual position scope: ABB assigns the orange spare to IRB 1600 axes 1 and 2
  • Pinion-inclusive motor: the official product identity includes the drive pinion
  • Supplier boundary: the motor pinion and gearbox must share the documented sub-supplier
3HAC044504-001 is the orange IRB 1600 frame-drive motor used at either of two mechanically different service positions.

The axis choice changes restraint, oil handling, cable access, and brake-release preparation even though the complete motor article remains the same.

A correct order therefore identifies both the article and installed gearbox lineage before work begins.
Apter Power can review 3HAC044504-001 label evidence, axis assignment, finish, pinion condition, and gearbox matching information.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Axis 1: the motor is mounted on the frame and uses R3.MP1
  • Axis 2: the motor is located at the front and uses R3.MP2
  • Brake pins: both procedures use pins 7 positive and 8 negative
  • Axis-2 restraint: support the lower arm before releasing its holding brake
  • Sub-supplier rule: motor pinion and gearbox must originate from the same supplier
  • Engagement: use rotation tool 3HAC022266-003 during gear mating
  • Gear play: set a barely noticeable clearance at multiple shaft positions
  • Fastening: finish the four M8x25 screws at 35 Nm
  • Joint preparation: clean the mating surfaces and remove burrs
  • O-ring: replace damage and seat the seal with Loctite 574
  • Axis 2: refill gearbox oil and perform the specified leak-down test
  • Release: recalibrate before the controlled first run
  • IRB 1600 axis-1 repair: restore the frame-mounted base-drive motor
  • IRB 1600 axis-2 repair: service the front motor with lower-arm restraint and oil recovery
  • SAMP drive matching: maintain gearbox and pinion supplier compatibility
  • Color-controlled sourcing: procure the ABB Orange rather than graphite-white configuration
Description
For the IRB 1600 frame, 3HAC044504-001 is ABB's orange rotating AC motor including pinion for axis 1 or axis 2. Its official technical record distinguishes this orange configuration from the graphite-white 3HAC050383-001 article.

Installation of 3HAC044504-001 depends on the exact axis. Axis 1 uses connector R3.MP1 and lifts vertically from the frame; axis 2 uses R3.MP2, requires the lower arm to be secured before brake release, and releases gearbox oil when the motor is withdrawn.

Before selecting 3HAC044504-001, verify the IRB 1600 variant, axis position, finish, and gearbox supplier. ABB states that a SAMP motor pinion and its mating gearbox must come from the same sub-supplier, so visual fit alone is not adequate compatibility evidence.
Alternative Names
3HAC044504001 ABB IRB 1600 axis 1 motor ABB IRB 1600 axis 2 motor IRB 1600 orange motor with pinion
Technical notes
3HAC044504-001 must be matched to an IRB 1600 gearbox from the same sub-supplier as the motor pinion. For axis 2, secure the lower arm before applying 24 V DC to R3.MP2 pins 7 and 8, collect released gearbox oil, and restore the specified gear play, seal, oil, calibration, and leak test.

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.
What compatibility check is mandatory before 3HAC044504-001 is fitted to a gearbox?
Confirm that the motor pinion and mating gearbox come from the same sub-supplier. ABB directs users to the compatible gearbox-and-motor table for the exact spare selection.
Which connector releases the brake when 3HAC044504-001 is used on axis 1?
Use R3.MP1 with 24 V DC, positive on pin 7 and negative on pin 8, then disconnect the temporary supply after installation.
Why must the lower arm be restrained when 3HAC044504-001 is used on axis 2?
Releasing the axis-2 holding brake makes the lower arm movable and able to fall. Secure its weight before applying brake-release power at R3.MP2.
How is gear play set after 3HAC044504-001 enters the gearbox?
Use the rotation tool to feel a barely noticeable play, tap the motor with a plastic mallet, and recheck at additional shaft positions before tightening to 35 Nm.
Which oil and sealing steps apply when 3HAC044504-001 is installed on axis 2?
Collect oil during removal, clean the joint, restore the O-ring with Loctite 574, refill the gearbox, and complete the ABB leak-down test.
What should procurement collect for an urgent 3HAC044504-001 request?
Send full nameplate photos, IRB 1600 variant and serial number, axis assignment, motor finish, gearbox and pinion markings, quantity, destination, and outage date.
