Configured for Axis 2 mechanical drive transmission in the ABB IRB 7600, the ABB 3HAC062340-003 (3HAC062340-003 Motor Including Pinion) converts controlled electrical input into rotational torque for the robot axis drive. ABB identifies this part as an Axis 2 Type B motor including pinion.

Model Identification

The 3HAC062340-003 is an ABB IRB 7600 Axis 2 Type B motor assembly. ABB lists the part under the Axis-2 motor spare-parts group and specifies the Graphite White version for applicable IRB 7600 configurations. The spare motor assembly includes the pinion, connection box, cover, and O-rings.

The ABB spare-parts documentation also distinguishes Type A and Type B motors. Type B motors replaced Type A motors, and the documentation states that the relevant Type A and Type B motors are fully interchangeable for the applicable axes.

Hardware Specifications

The approximately 12.47 kVA value is calculated from the supplied 400 V 3-phase and 18 A ratings using the standard 3-phase apparent-power relationship. It is not a measured real-power consumption value.

Axis 2 Drive Characteristics

The 3HAC062340-003 is specifically associated with Axis 2 of the IRB 7600. ABB's spare-parts table lists 3HAC062340-003 alongside 3HAC062340-004 for the Axis 2 Type B motor configuration.

The motor assembly includes the pinion as part of the spare-part configuration. ABB also specifies the connection box, cover, and O-rings as included components of the spare motor assembly.

The 48 Nm rated torque and 1500 RPM rated speed correspond to the supplied motor data. The stated 3000 RPM maximum speed defines a higher operating speed limit and should not be treated as the continuous rated operating point.

ABB Drive and Feedback Interface

The 20-bit resolution value supplied for this motor indicates a high-resolution feedback configuration associated with the robot servo system. Feedback compatibility must be maintained with the corresponding ABB controller and drive configuration.

The 400 V AC, 3-phase and 18 A values describe the supplied motor electrical ratings. They should not be used as a standalone replacement criterion because the motor also has a defined mechanical pinion interface and robot-axis assignment.

ABB identifies 3HAC062340-003 as an IRB 7600 Axis 2 spare part rather than as a general-purpose industrial motor.

Thermal Characteristics

The supplied thermal time constant is 45 minutes. The stated maximum winding temperature is 155 deg C, corresponding to Class F insulation.

The supplied standard ambient range is 0 deg C to +40 deg C. Above 40 deg C, the supplied derating factor is 1% per deg C.

The derating value should be applied to the applicable motor rating according to the manufacturer's thermal operating curve. It should not be interpreted as a universal reduction in robot payload or controller output.

Mechanical Configuration

The 3HAC062340-003 is a Type B motor including pinion. ABB's spare-parts documentation specifies Graphite White for this part number and identifies it within the Standard / Foundry protection category.

ABB documentation states that the Type B motor includes an oil seal that is inspected as part of periodic maintenance when replacing a Type A motor with a Type B motor.

The pinion should therefore be treated as an integral part of the mechanical replacement assembly. Shaft alignment and gear engagement must be checked before commissioning.

Field Installation Guidelines

Mechanical Installation

• Confirm part number 3HAC062340-003 before removing the existing motor.
• Verify that the motor position is Axis 2 on the applicable IRB 7600 configuration.
• Confirm that the installed motor is the Type B configuration.
• Inspect the pinion for tooth wear, impact damage, contamination, or deformation.
• Check the mating gear before installing the replacement motor.
• Keep the pinion and mating gear free from foreign material.
• Align the motor assembly correctly before securing the mounting hardware.
• Do not apply uncontrolled axial or radial loading to the motor shaft.

Electrical Installation

• Isolate robot and drive power before disconnecting the motor.
• Verify motor power and feedback connector identification.
• Inspect connectors for bent contacts, contamination, or mechanical damage.
• Verify protective earth continuity before energization.
• Keep motor power wiring separated from low-level signal wiring where practical.
• Confirm the motor and feedback configuration in the ABB controller before enabling motion.

Thermal Installation

• Maintain the specified ambient operating range where possible.
• Apply the supplied 1% per deg C derating above 40 deg C when evaluating thermal operating conditions.
• Do not exceed the stated 155 deg C maximum winding temperature.
• Provide sufficient airflow around accessible motor surfaces where the robot installation permits.
• Investigate abnormal motor temperature before continuing high-duty operation.

Commissioning

• Check free mechanical movement before applying servo power.
• Verify feedback response before commanding normal robot movement.
• Perform initial movement at controlled speed.
• Monitor motor current, vibration, acoustic noise, and position error.
• Confirm axis calibration after motor replacement according to the applicable ABB procedure.
