ABB 3HAC058991-003 Robot Compatible Servo Motor

ABB 3HAC058991-003 Product Details
Basic Identification
The model prefix 3HAC belongs to the ABB industrial robot complete machine spare parts coding system. This model is an ABB robot’s servo motor (small joint drive motor), compatible with small lightweight six-axis collaborative/industrial robots such as IRB120 and IRB1200, responsible for precise drive of the robot’s small arm and wrist joints.

Core Function
As the power core of the robot’s 2/3/5/6 small joints, it realizes high-speed point motion and precise assembly trajectory control;
It is mostly used in 3C small component assembly, small component handling, grinding loading/unloading scenarios, replacing old faulty joint motors to complete the overall machine maintenance and replacement;
It is an original factory standard spare part, equipped with an internal encoder, closed-loop feedback of rotation angle and speed, ensuring the repeatability positioning accuracy.
Key Parameter Highlights
Power Supply Specifications: Servo drive power supply for the robot control cabinet (conventional 48V level)
Integrated Components: Built-in high-precision absolute value encoder, no need for additional external positioning elements

Compatible Models:

Mainly compatible with IRB120 and IRB1200 small robots’ corresponding joint positions
Working Condition Compatibility: Protection level compatible with the robot joint sealed installation environment, capable of withstanding high-frequency start-stop, reciprocating swing loads
Maintenance Features: Modular integrated structure, direct disassembly and replacement is possible without modifying the control cabinet program parameters
Distinguishing from the components you previously queried
Previously, RMU610A/cRBX01/MB810/CTB811 belonged to the Symphony Plus power plant DCS control system components, targeting process industrial control;
3HAC057980-003 belongs to industrial robot motion execution spare parts, targeting production line manipulators, belonging to two independent product lines.

Application Scenarios
Joint fault maintenance and equipment upgrade for lightweight robot workstations such as electronic component assembly, small component sorting, desktop-level precise loading/unloading, and small component grinding.
