ABB 3HAWC116592 / 3HAWC116593-/00 – High-Torque Servo Motor | IRB Robot Drive Platform
Engineering Background
The ABB 3HAWC116592 (assembly reference) and 3HAWC116593-/00 (variant suffix) are factory-designated servo motor units engineered for ABB’s IRB-series industrial robot arms. These motors serve as the primary joint-drive actuators, delivering precise torque, speed, and positional feedback in closed-loop motion control architectures. Designed to IEC 60034 and ABB internal mechanical standards, they are built for continuous-duty operation in demanding manufacturing environments.
Product Positioning
Konmask.com supplies this unit as a verified OEM-equivalent replacement for maintenance engineers and system integrators managing ABB robot fleets. Whether you are performing scheduled preventive maintenance or responding to an unplanned axis failure, this servo motor provides a drop-in solution with no firmware re-parameterization required when paired with the original ABB drive controller.

System Architecture & Signal Flow
In the ABB IRB robot control architecture, the servo motor interfaces directly with the axis computer board (DSQC) via the ABB drive unit (rectifier + inverter module). The motor receives PWM-modulated voltage commands from the drive, while the integrated encoder feeds back position and velocity data to the robot controller (IRC5 / S4C+). The 3HAWC116592/3HAWC116593 unit occupies the joint-axis position in this closed-loop chain, ensuring sub-millimeter repeatability across the robot’s working envelope.
Signal path: IRC5 Controller → DSQC Axis Computer → Drive Unit → 3HAWC116593 Servo Motor → Encoder Feedback → IRC5

Technical FAQ
Q: Is 3HAWC116592 the same as 3HAWC116593?
A: 3HAWC116592 is the assembly-level part number; 3HAWC116593-/00 is the variant/revision suffix. Both refer to the same servo motor unit and are cross-referenced in ABB’s spare parts catalog.
Q: Which robot axes does this motor serve?
A: This unit is typically used on axes 1–3 (primary arm joints) of the IRB series, but always verify against your robot’s axis configuration drawing.
Q: Can this motor be used with a non-ABB drive?
A: Not recommended. The motor’s encoder protocol and connector pinout are optimized for ABB drive units. Third-party drive integration requires custom engineering.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock units have a 2–4 week lead time. Contact us to confirm current availability.
Q: Do you provide installation guidance?
A: Yes. Our technical team can provide ABB robot servo replacement procedures and torque specifications upon request.
