Compatible Replacement & Equivalent Models
When the original 3HAC055450-003 is unavailable or cost-prohibitive, the following verified equivalents and cross-references apply:
- 3HAC057542-003 – OEM variant for IRB 6640 axis drive
- 3HAC043453-003 – OEM variant for IRB 6700 axis drive
- Third-party servo motors with matching frame size, encoder resolution, and torque rating may be considered — contact our engineers for compatibility verification before ordering.
Note: Always verify encoder type (resolver vs. absolute multi-turn) and connector pinout before substituting any servo motor in an ABB robot system.
Why Choose the Original Model
- ✅ Plug-and-play compatibility with ABB IRC5 / OmniCore controllers — no parameter re-tuning required
- ✅ Matched inertia and torque curve for IRB 6640 / IRB 6700 payload ratings
- ✅ Integrated pinion eliminates backlash risk from aftermarket coupling
- ✅ ABB warranty compliance maintained when using genuine parts
- ✅ Certified for IP67 wash-down and foundry/clean-room variants
Typical Applications
- Automotive body welding and assembly lines (IRB 6640 / IRB 6700)
- Heavy-payload material handling and palletizing
- Machine tending and press-tending cells
- Foundry and harsh-environment robot installations
- Axis 1–6 motor replacement during scheduled maintenance or after fault codes (e.g., 50071, 50072)
System Compatibility
- Robot Models: IRB 6640 (all variants), IRB 6700 (all variants)
- Controllers: ABB IRC5 (M2004, M2000A), OmniCore C90XT
- Drive Units: DSQC 661 / DSQC 662 axis computer boards
- Software: RobotWare 5.x / 6.x compatible
Selection Guide
Use the checklist below to confirm the correct motor for your application:
- ☐ Confirm robot model: IRB 6640 or IRB 6700
- ☐ Identify axis number (Axis 1–6) — different axes may use different motor variants
- ☐ Check existing part label on motor body for 3HAC prefix
- ☐ Verify encoder type: resolver or absolute multi-turn encoder
- ☐ Confirm payload variant (e.g., IRB 6700-150/3.2 vs. IRB 6700-235/2.65)
- ☐ Check if foundry (F) or clean-room (C) protection class is required
Not sure? Send us your robot serial number and axis fault code — our team will confirm the correct part within 24 hours.

Replacement & Compatibility FAQ
Q: Can 3HAC057542-003 replace 3HAC055450-003 directly?
A: These are cross-reference variants for different robot models. Confirm your robot model before substituting — physical connectors and encoder wiring may differ.
Q: Is a refurbished motor safe for production use?
A: Yes, when sourced from a certified remanufacturer with documented test reports. We provide full test certificates on request.
Q: Do I need to re-calibrate the robot after motor replacement?
A: Yes. ABB requires axis calibration (fine calibration or revolution counter update) after any motor replacement. Refer to ABB Product Manual 3HAC020999-001.
Q: What fault codes indicate motor failure on IRB 6640 / IRB 6700?
A: Common codes include 50071 (motor current error), 50072 (motor overtemperature), and 50074 (encoder fault). Contact us with your fault log for diagnosis support.
