The Atlas Copco Motor 1080407404 is a precision-engineered electric drive unit designed for use in screw air compressor systems. Built to OEM dimensions and tolerances, it serves as a reliable replacement for original motors, restoring compressor performance with stable torque output, excellent cooling characteristics, and mechanical reliability. This motor is ideal for continuous-duty industrial compressor applications where durability and energy efficiency matter.
Technical & Design Highlights
- Robust Construction
The motor’s housing is cast from high-strength ductile iron or equivalent alloy, providing excellent rigidity, vibration damping, and protection from mechanical stress. - Optimized Cooling and Ventilation
Finned surfaces and internal airflow pathways are designed to facilitate heat dissipation under load, preventing overheating of the windings and extending insulation life. - Precision-Balanced Rotor
The rotor assembly is dynamically balanced to minimize vibration, reduce bearing wear, and maintain alignment with the driven screw compressor element. - High-Grade Windings & Insulation
Copper windings (or high-quality conductive material) are insulated with Class F or better materials, ensuring thermal resilience in continuous operation. - Sealed Bearings & Shaft Protection
High-quality sealed bearings protect against contamination, moisture, and dust—critical in harsh industrial environments.
Quality Assurance & Testing Process
Each motor undergoes a rigorous inspection and testing workflow, including:
- No-load testing — verifying voltage, current draw, rotational behavior without load.
- Load testing — simulating compressor loads to confirm torque, thermal behavior, and performance stability.
- Insulation resistance & dielectric strength tests — ensuring electrical safety and insulation integrity.
- Dynamic balance & vibration analysis — confirming smooth operation within acceptable vibration thresholds.
- Endurance & thermal rise trials — operating under continuous duty to verify heat management and stability.
Only motors that pass all test phases are approved for packaging and shipment.
Installation & Compatibility
- OEM Fitment
Designed to match the original motor in mounting footprint, shaft diameter, and coupling arrangements, enabling plug-and-play replacement in most machines. - Electrical Matching
Ensure the replacement voltage, frequency, and phase match your compressor system (e.g. 400 V / 50 Hz or region-specific power supply). - Application Scope
Suitable for screw air compressors in industrial settings such as manufacturing, workshops, pneumatic lines, and any continuous-duty installation.
If your existing motor or nameplate data corresponds to “1080407404,” this unit can be installed without major modifications.

Usage & Maintenance Recommendations
To ensure optimal lifetime:
- Maintain ventilating paths free from dust, oil, or debris
- Use the proper voltage and protect from overcurrent or imbalances
- Monitor bearing temperature and vibration regularly
- Periodically test winding insulation resistance
- Align the motor shaft with the compressor coupling precisely
Even high-quality motors can fail prematurely if cooling is blocked, alignment is poor, or electrical anomalies persist.
