ABB 3HAC037820-002 / 3HAC055688-003 / 3HAC055697-003 – Three-Axis Motor Module | IRB7600 & IRB6700 Series
Engineering Background
The ABB IRB7600 and IRB6700 series represent ABB Robotics’ flagship heavy-payload industrial robot platforms, widely deployed in automotive body-in-white welding, press-tending, foundry handling, and heavy material transfer. The three-axis motor module — covering part numbers 3HAC037820-002 (IRB7600), 3HAC055688-003 (IRB6700-300), and 3HAC055697-003 (IRB6700-200) — is the core electromechanical drive assembly responsible for axes 1–3 motion control, directly determining robot repeatability, load capacity, and cycle-time performance.
Product Positioning
Konmask.com supplies this module as an OEM-equivalent replacement and spare part for maintenance engineers and system integrators requiring verified, traceable components with rapid global fulfillment. Each unit is sourced through qualified supply channels and undergoes incoming inspection before dispatch.

Proven Application Environments
- Automotive Manufacturing: Body-in-white spot welding, press-tending lines, and chassis assembly requiring high repeatability (<0.05 mm) and heavy payload (200–300 kg).
- Foundry & Die Casting: High-temperature, high-vibration environments where motor thermal stability and IP protection are critical.
- Heavy Material Handling: Palletizing, machine tending, and transfer operations with continuous duty cycles.
- Aerospace & Defense MRO: Precision component handling requiring certified, traceable spare parts.
- General Industrial Automation: Any IRC5-controlled IRB7600 or IRB6700 installation requiring axis 1–3 motor replacement or preventive maintenance stock.
Engineering Advantages
- Direct OEM Compatibility: Exact mechanical and electrical interface match — no modification required for installation.
- Verified Part Numbers: Each unit ships with label verification of 3HAC037820-002, 3HAC055688-003, or 3HAC055697-003 as applicable.
- Reduced Downtime Risk: In-stock availability enables same-week dispatch, minimizing production line stoppage costs.
- Broad Robot Coverage: Single sourcing point for three critical IRB7600/IRB6700 variants simplifies procurement and inventory management.
- IRC5 Plug-and-Play: Compatible with ABB IRC5 controller family; no firmware modification required post-installation.
System Architecture & Signal Flow
In the IRB7600/IRB6700 drive architecture, the IRC5 controller’s drive module outputs PWM signals to the three-axis motor assembly via the robot’s internal cable harness. The motor module integrates resolver or encoder feedback directly to the drive unit, enabling closed-loop position and torque control. Axes 1–3 govern the robot’s primary reach envelope (base rotation, lower arm, upper arm), making this module the highest-impact assembly for overall robot kinematic performance.
Signal path: IRC5 Drive Module → Motor Power Cable (3HAC) → Three-Axis Motor Assembly → Resolver/Encoder Feedback → IRC5 Measurement Board
