Axis 2 Servo Motor with Pinion and O-Ring — Technical Overview

Specifications

Category Industrial robot servo motor — compact axis motor with pre-installed pinion and sealing o-ring
Brand ABB
Function Drives axis 2 rotation of the compatible ABB robot. Works together with the IRC5 controller and the axis-2 drive unit to deliver closed-loop position control in compact, space-limited robot installations.
Definition ABB OEM rotary AC servo motor supplied as a single matched assembly with a pinion pre-mounted on the motor shaft and a sealing o-ring pre-installed at the factory. Designed as a direct replacement for the original axis-2 motor in the compatible ABB robot series.
Series Compatibility Information not officially documented for this exact part number in our reference set. The official ABB catalog lists this motor under Axis 2 motor incl. pinion & o-ring without specifying a single robot family, suggesting it may be used across several ABB IRB models. Please confirm compatibility against your robot serial number and RobotWare version before ordering.
Net Weight 5.62 kg
Net Dimensions (L × H × W) 300 × 110 × 110 mm
Pinion Pre-installed and factory matched to the axis-2 gearbox. No separate gear pressing required at installation.
O-Ring Sealing o-ring pre-installed between the motor flange and the gearbox housing. Reuse the existing o-ring groove orientation when fitting.
Customs Tariff Number 85015220
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

  • Small-payload ABB robots where the axis-2 motor space is constrained by the robot’s compact mechanical envelope.
  • Painting, dispensing, and small-parts handling cells that rely on precise axis-2 motion under continuous duty cycles.
  • Pick-and-place and light assembly stations driven by ABB IRC5 controllers.
  • Lab, electronics, and pharmaceutical automation lines using compact ABB robot models.
  • General industrial automation cells requiring replacement of a worn axis-2 motor in compact-format ABB robots.

Design Purpose

The motor converts electrical energy from the axis-2 drive unit into controlled mechanical rotation of the robot’s axis-2 joint. The integrated pinion meshes directly with the axis-2 gearbox to transmit torque, while the built-in resolver/encoder feeds back precise rotor position to the IRC5 controller.

By delivering the motor, pinion, and sealing o-ring as a single matched unit, ABB removes the gear-pressing step at installation and guarantees the seal is correctly seated before the motor leaves the factory — important in compact robot designs where the axis-2 cavity is tight and difficult to re-seal in the field.

Common Failure Modes

  • Overcurrent or overheat tripping — the drive unit reports motor overload after continuous duty cycles.
  • Encoder / resolver feedback loss — axis 2 shows position drift or alarms during homing.
  • Holding brake failure — the axis-2 link sags or drops immediately when the servo is switched off.
  • O-ring seal failure — oil or grease leaks from the motor-to-gearbox interface, often caused by aged rubber, incorrect re-assembly, or chemical attack from cleaning agents.
  • Pinion wear or abnormal noise — worn pinion teeth produce chatter or vibration under load.
  • Insulation degradation or ground fault — the axis-2 drive trips the moment the motor is enabled.
