ABB 3HAC055448-004 Robot Servo Motor

Product Description

The 3HAC055448-004 is an original ABB robot joint servo motor assembly used for specific IRB series industrial robots. It comes with built-in holding brake and high-precision encoder, providing stable torque and accurate position control for robot joint movement. It is a critical spare part for robot joint maintenance and replacement.

Features

• Complete servo motor assembly integrated with holding brake and high-resolution encoder
• High torque and low inertia design for smooth and fast joint movement
• Strong resistance to vibration and temperature variation for continuous industrial operation
• Ready-to-install unit for direct substitution of defective joint motors
• Compact structure to match the narrow installation space of robot joints
• High positioning repeatability to meet robotic precision requirements

Application Scenarios

• ABB IRB robot joint overhaul and spare parts replacement
• Automotive welding, assembly and material handling robot stations
• Palletizing, packaging and process automation robotic cells
• Factory robot spare parts inventory and renovation projects
