HAC048234-001 3HAC055448-003ABB IRB67003HAC055448-003 Product Description

The ABB 3HAC055448-003 is a precision-engineered rotating AC servo motor purpose-built for the IRB 6700 robot series, one of ABB's most widely deployed heavy-payload industrial robots. Designed to operate as a fully integrated drive component within ABB's IRC5 control architecture, this motor delivers the torque density, thermal stability, and encoder resolution required for high-cycle manufacturing environments. Whether deployed in automotive body-in-white welding lines, foundry tending, palletizing, or heavy material handling, the 3HAC055448-003 ensures consistent axis performance across the full operational envelope of the IRB 6700 platform.

At NANKMOS, every 3HAC055448-003 unit is sourced through verified industrial supply channels, pre-shipment tested for electrical continuity and mechanical integrity, and backed by a 12-Month Warranty covering manufacturing defects and functional failures. Global logistics support ensures rapid deployment to manufacturing sites across Asia, Europe, the Middle East, and the Americas.

The 3HAC055448-003 does not operate in isolation — it is a load-bearing node within a tightly coupled ABB robotics control architecture. Understanding its system role requires examining how it interacts with every layer of the IRC5 platform and the broader automation cell.

At the control layer, the IRC5 Main Computer (DSQC1000) executes RAPID motion programs and dispatches interpolated axis commands to the Axis Computer (DSQC668 or DSQC1015). These commands are translated into PWM drive signals delivered to the motor through the ABB Drive Unit (DSQC661 / DSQC662). The 3HAC055448-003 receives these signals and converts electrical energy into precise rotational torque, with resolver feedback closing the position loop back to the Axis Computer in real time.

At the power layer, the ABB Power Supply Unit (DSQC609) conditions incoming three-phase AC into the regulated DC bus voltage that feeds the drive units. Stable DC bus voltage is critical to motor performance — voltage ripple or transient spikes directly affect torque linearity and encoder signal integrity. The 3HAC055448-003 is rated to operate within the DC bus parameters defined by the IRC5 drive architecture, ensuring compatibility without derating.

At the I/O layer, the ABB DSQC652 Digital I/O Board and DSQC643 Analog I/O Board manage peripheral signals — conveyor interlocks, gripper solenoids, safety gate inputs — that coordinate robot motion with the surrounding production cell. While these boards do not directly interface with the motor, their signal timing directly influences when axis motion commands are issued, making I/O latency a system-level concern for high-speed pick-and-place or press-tending applications.

At the communication layer, the IRC5 controller supports DeviceNet, PROFIBUS, EtherNet/IP, and PROFINET via optional fieldbus adapter boards (DSQC658 / DSQC688). These protocols allow the robot controller to receive production commands from upstream PLCs — such as ABB AC500 or Siemens S7-1500 — and report axis status, cycle counts, and fault codes downstream to SCADA or MES systems. The 3HAC055448-003's resolver feedback data is aggregated at the Axis Computer and made available to the IRC5 OPC-UA server for real-time diagnostics.

At the HMI layer, the ABB FlexPendant (IRC5 teach pendant) provides operators with direct axis jogging, program loading, and fault acknowledgment. Motor-related faults — overcurrent, resolver loss, thermal overload — are surfaced as RAPID error codes on the FlexPendant, enabling rapid diagnosis without external instrumentation. Integration with ABB RobotStudio allows offline simulation of axis trajectories before live commissioning, reducing the risk of mechanical interference during initial deployment.

At the protection layer, the IRC5 Electronic Position Switch (EPS / DSQC646) enforces software-defined safety zones, preventing axis motion beyond configured limits even in the event of a program error. Thermal protection within the 3HAC055448-003 itself triggers a drive fault before winding temperatures reach damaging levels, protecting both the motor and the connected mechanical transmission.

For redundancy and high-availability deployments, the IRB 6700 can be paired with an IRC5 Panel Mounted Controller (PMC) in a dual-cabinet configuration, allowing drive units to be serviced without full system shutdown. Spare motor inventory — including the 3HAC055448-003 alongside complementary axis motors such as the 3HAC044075-001 and 3HAC026253-001 — should be maintained on-site for critical production lines to minimize mean time to repair (MTTR).

Automotive Manufacturing: In body-in-white welding and assembly lines, the IRB 6700 equipped with 3HAC055448-003 motors handles spot welding guns, laser welding heads, and press-fit tooling at cycle times under 10 seconds. The motor's torque consistency across thousands of daily cycles is essential for weld quality repeatability and dimensional accuracy of body panels.

Foundry & Metal Casting: In die-casting and sand-casting environments, the IRB 6700 Foundry Plus variant — using IP67-rated motors including the 3HAC055448-003 — operates in high-temperature, high-particulate atmospheres. The motor's sealed construction and thermal class F insulation allow continuous operation in ambient temperatures up to 50°C without derating.

Palletizing & Logistics: High-payload palletizing cells rely on the IRB 6700's reach and payload capacity. The 3HAC055448-003 drives the primary load-bearing axes, where consistent torque delivery at low speeds is critical for stable layer formation and pallet integrity. Integration with conveyor PLCs via EtherNet/IP ensures synchronized robot-conveyor motion without manual handshaking.

Petrochemical & Energy: In hazardous-area adjacent applications — valve actuation, pipe handling, and drum filling — the IRB 6700 with IRC5 SafeMove2 provides certified safe-speed and safe-zone monitoring. The 3HAC055448-003's resolver feedback supports SafeMove2's dual-channel position monitoring, enabling collaborative operation near human workers without full guarding.

Semiconductor & Electronics: While the IRB 6700 is a heavy-payload platform, it is deployed in semiconductor fab logistics for wafer cassette transport and equipment loading. In these environments, motor cleanliness and vibration characteristics are critical. The 3HAC055448-003's balanced rotor design minimizes vibration transmission to sensitive equipment during approach and retract motions.

Q1: Is the 3HAC055448-003 compatible with all IRB 6700 variants, and does it require firmware updates on the IRC5 controller? The 3HAC055448-003 is designed for the IRB 6700 series across standard payload variants (150/200/235/300/400/500 kg). Compatibility with a specific axis position should be confirmed against the robot's mechanical unit configuration file (MOC.cfg). No firmware update is typically required for motor replacement, but the IRC5 system should be running RobotWare 6.x or later for full resolver calibration support. NANKMOS provides pre-shipment documentation including part revision and test records to support commissioning.

Q2: What is the recommended installation and calibration procedure when replacing a 3HAC055448-003 in a live production environment? Motor replacement on the IRB 6700 requires axis brake release, mechanical disconnection of the motor flange, resolver cable re-termination, and fine calibration using the IRC5 calibration routine (Levelmeter or CalPendulum method). NANKMOS recommends scheduling replacement during planned maintenance windows. Each unit shipped includes a test report confirming resolver output linearity and insulation resistance, reducing on-site verification time. Full calibration documentation is available upon request.

Q3: What does the 12-Month Warranty cover, and what is the process for warranty claims? The 12-Month Warranty covers manufacturing defects, resolver failure, winding insulation breakdown, and bearing failure under normal operating conditions. It does not cover damage resulting from incorrect installation, voltage transients outside IRC5 drive specifications, or mechanical overload beyond rated torque. To initiate a warranty claim, contact NANKMOS at [email protected] with the unit serial number, purchase date, and fault description. Replacement units are dispatched within 5 business days of claim approval, with return logistics coordinated by NANKMOS.
