Genuine Atlas Copco Part 1092090381: High-Performance 55KW Three-Phase Induction Motor

Industrial air compressor systems demand absolute reliability and uncompromising power to maintain plant uptime. Within a compressed air network, the main drive motor serves as the heart of the entire operation. Consequently, choosing a factory-original component remains the only way to guarantee optimal performance, long-term safety, and precise equipment compatibility. The genuine Atlas Copco part number 1092090381 represents a premium three-phase induction motor engineered specifically to power heavy-duty industrial screw compressors under the most demanding environments.

Engineered for Extreme Industrial Conditions

Standard off-the-shelf industrial motors often fail prematurely when subjected to the high-heat, continuous-load interior environments of an air compressor canopy. To overcome this challenge, this authentic Atlas Copco motor incorporates highly specialized technical features that distinguish it from standard electrical motors.

• Extended Ambient Temperature Tolerance (+46°C): While conventional motors only support operations up to 40°C, this genuine component safely withstands continuous full-load operations in ambient temperatures reaching up to +46°C.
• Superior Service Factor (SF 1.15): Screw compressors frequently encounter brief periods of workload spikes during the final stages of the loading cycle. Thanks to its 1.15 service factor, this motor provides a 15% power reserve to handle transient overloads without overheating or tripping.
• Premium IE2 Energy Efficiency: Operating at a full-load efficiency of 93.2%, this motor significantly lowers factory electricity consumption, drastically reducing the total cost of ownership over its lifespan.
• Robust IP55 and Class F Protection: Severe dust and moisture commonly challenge compressor rooms. Therefore, the IP55-rated enclosure prevents particle ingress, while Class F insulation protects internal windings up to 155°C.

Comprehensive Technical Specifications

To facilitate a precise technical evaluation by procurement managers and maintenance engineers, the complete electrical and physical parameters of part number 1092090381 are compiled in the detailed specification table below.

Equipment Application and Compatibility

Beyond raw technical data, verified machine compatibility ensures a seamless installation process without structural modifications. This main drive induction motor is designed exclusively for Atlas Copco GA series oil-injected rotary screw air compressors, particularly within the GA55 and GA55+ power brackets. Because it conforms precisely to the factory-defined shaft dimensions, mounting bolt configurations, and cooling duct positions, it allows maintenance teams to achieve a true plug-and-play replacement, minimizing costly production downtime.

Frequently Asked Questions (FAQ)

In addition to reviewing technical documentation, international procurement teams often require clarity on specific deployment aspects. To streamline your purchasing workflow, we have answered the most common inquiries regarding this authentic component below.

Q1: Is this motor part number 1092090381 a brand-new original component?

Yes. We supply exclusively 100% brand-new, factory-authentic Atlas Copco components. Every unit undergoes rigorous quality assurance protocols to ensure it matches the precise engineering standards specified by the original equipment manufacturer.

Q2: Why does this motor perform better than standard 55KW industrial motors?

Standard industrial motors generally lack the insulation and service factor margins required for compressor duty cycles. In contrast, this component features a 1.15 service factor and a 46°C ambient temperature threshold, allowing it to survive continuous, heavy-duty 24/7 operations where generic motors fail.

Q3: What are the installation requirements for this specific drive motor?

Since this component features a dedicated YXLA250M1-2 frame with pre-aligned factory mountings, it integrates directly with your existing compressor coupling or gearbox setup. Always verify that your starter panel supports the 93.8A full-load current and standard Delta connection before commissioning.
