Axis 2 Rotary AC Servo Motor with Pinion — Technical Overview

Specifications

Category Industrial robot servo motor — axis motor with pre-installed pinion
Brand ABB
Function Drives axis 2 (upper arm) rotation of ABB IRB 6700 robots. Works together with the IRC5 controller and the axis-2 drive unit to deliver torque and closed-loop position control under heavy-payload operation.
Definition ABB OEM rotary AC servo motor supplied with a pinion pre-mounted on the motor shaft. Designed as a direct replacement for the original axis-2 motor in IRB 6700 robots. ABB references the same motor under related part numbers 3HAC043453-003 (IRB 6700 equivalent) and 3HAC057542-003 (IRB 6640 equivalent) depending on the configuration in which it was originally shipped.
Series Compatibility ABB IRB 6700 industrial robots, axis 2. Related cross-reference part numbers: 3HAC043453-003 (IRB 6700 equivalent) and 3HAC057542-003 (IRB 6640 equivalent). Please confirm your robot model and the affected axis before ordering.
Pinion Pre-installed and dynamically matched to the axis-2 gearbox. No separate gear pressing required at installation.
Detailed Electrical / Mechanical Parameters Information not officially documented in our reference set for this exact variant. Please send your inquiry with the robot serial number and RobotWare version, and we will provide the matching datasheet.

Industrial Applications

  • Heavy-payload material handling — moving large castings, forgings, and steel parts between workstations.
  • Machine tending — loading and unloading CNC machining centers, presses, and injection molding machines.
  • Spot welding and large-body assembly in automotive body shops.
  • Palletizing and depalletizing of heavy packaged goods at end-of-line.
  • Foundry and forge part transfer under high-duty cycle conditions.

Design Purpose

The motor converts electrical energy from the axis-2 drive unit into controlled mechanical rotation of the robot's upper arm. The integrated pinion meshes directly with the axis-2 gearbox, transmitting torque to the upper arm while the built-in resolver/encoder feeds back precise rotor position to the IRC5 controller. By delivering the motor and pinion as a single matched assembly, ABB removes the gear-pressing step at installation and ensures backlash stays within factory tolerance.

Common Failure Modes

  • Overcurrent or overheat tripping — the drive unit reports motor overload after heavy-duty cycles.
  • Encoder / resolver feedback loss — axis 2 shows position drift or alarms during homing.
  • Holding brake failure — the upper arm sags or drops immediately when the servo is switched off.
  • Abnormal noise or vibration from axis 2 — typically caused by worn pinion teeth, bearing damage, or contamination inside the motor.
  • Insulation degradation or ground fault — the axis-2 drive trips the moment the motor is enabled.

For a step-by-step root-cause procedure and replacement workflow, we recommend publishing an on-site article such as "ABB Robot Axis Motor Troubleshooting Guide" and linking it here. The link can be inserted once the article is published.

Why Choose Us

  • Focused ABB robot spare-parts supplier covering servo motors, drive units, gearboxes, and teach pendants for IRB-series robots.
  • Each axis motor is inspected and tested (encoder signal, insulation resistance) before packing.
  • Cross-reference support — if your unit was originally shipped under 3HAC043453-003 or 3HAC057542-003, we can confirm compatibility against your robot serial number.
  • 12-month warranty with remote technical support for installation and commissioning questions.
  • Multiple payment methods accepted — PayPal, T/T, and Alibaba Trade Assurance.
