Industrial Robot Axis Drive Solution – ABB DSQC626 3HAC020465-001 | DSQC400 Series
Where This Product Is Used
The ABB DSQC626 (OEM part number 3HAC020465-001) is a rotational AC servo motor engineered for precision axis actuation inside ABB industrial robot arms. It is the primary motion element on axis 4, 5, or 6 of the IRB series, delivering the torque and positional accuracy that automated production lines demand.
- Automotive body welding & spot-welding cells – maintains sub-millimetre repeatability at high cycle rates
- Electronics PCB assembly & pick-and-place – smooth low-inertia rotation for delicate component handling
- Palletising & material handling – continuous-duty torque for heavy-payload end-of-arm tooling
- Painting & coating booths – sealed construction tolerates solvent-rich environments
- Food & beverage packaging – hygienic-grade operation compatible with washdown protocols
- Pharmaceutical & medical device assembly – low-vibration motion meets cleanroom requirements

Application-Specific FAQ
Q: Is the DSQC626 a direct drop-in for the DSQC400 (3HAC025062-003)?
A: Yes. The DSQC626 / 3HAC020465-001 is the OEM successor to the DSQC400 / 3HAC025062-003 with identical mounting dimensions and connector pinout. No software parameter changes are required on IRC5 controllers.
Q: Which ABB robot models use this motor?
A: It is most commonly found in the IRB 140, IRB 1400, IRB 1600, IRB 2400, and IRB 4400 families on wrist axes 4–6. Always verify against your robot’s spare-parts manual (3HAC-XXXXX) before ordering.
Q: Can this motor be used with a non-ABB controller?
A: The motor is a standard AC servo with resolver feedback. Third-party servo drives with compatible resolver input and matching power ratings can drive it, but tuning and safety validation are the integrator’s responsibility.
Q: What warranty is provided?
A: New units carry the standard ABB OEM warranty. Refurbished units are covered by Konmask’s 90-day functional warranty. Extended warranty options are available on request.
Q: Do you provide installation support?
A: We provide technical documentation and remote guidance. On-site commissioning services can be arranged through our partner network – contact us for details.
