1091631955 Industrial Motor
Product Description
In industrial compressed air systems, the integrity of every single component directly dictates operational efficiency and system longevity. The Genuine Atlas Copco 1091631955 Industrial Motor stands as a core power unit engineered specifically to sustain the rigorous demands of Atlas Copco air compressors and purification systems. As an authentic, factory-certified original equipment part, this motor guarantees seamless integration, eliminating the operational risks associated with non-standard components.
Technical Specifications and Grid Versatility
The 1091631955 motor features an advanced dual-frequency design, allowing it to deliver optimized, stable performance across both 50 Hz and 60 Hz global electrical grids. Built to meet the stringent International Electrotechnical Commission standard (IEC60034-1), its digitalized nameplate parameters are detailed below:
| Technical Indicator | 50 Hz Operational Status | 60 Hz Operational Status |
|---|---|---|
| Output Power | 5.5 kW (approx. 7.5 HP) | 5.5 kW (approx. 7.5 HP) |
| Rated Speed | 2840 r/min | 3400 r/min |
| Rated Voltage | 400 / 690 V (Three-Phase AC) | 400 / 690 V (Three-Phase AC) |
| Rated Current | 10.4 / 6.01 A | 10.4 / 6.01 A |
| Connection Type | Delta (Δ) / Star (Y) | Delta (Δ) / Star (Y) |
| Power Factor (cos φ) | 0.88 | 0.88 |
| Energy Efficiency Class | IE2 - 87.0% | IE2 High Efficiency Range |
Premium Construction and Mechanical Integrity
Every structural element of the 1091631955 motor is tailored to withstand the harsh internal environment of industrial machinery rooms:
Mechanical Structure & IM B34 Mounting
Features the rigid HJA 112M-2 frame architecture integrated with a specialized horizontal foot-mounting and a precisely machined small flange. This unique configuration minimizes vibration and ensures exact coaxial alignment with the air-end or cooling fan hub, protecting flexible couplings from premature wear.
Environmental Protection & Advanced Insulation
Engineered with a robust IP55 dust-proof and water-resistant envelope coupled with a high-tier Class F insulation system. This complete electrical defense safeguards internal components against airborne particulates, heavy moisture, and severe thermal cycling without dielectric breakdown.
Heavy-Duty C3 Mechanical Bearings
Equipped with premium 6306-2Z/C3 deep groove ball bearings on both the Drive End (DE) and Non-Drive End (NDE). The specialized C3 large clearance design ensures smooth, high-velocity rotation and prevents thermal locking under continuous industrial loads.
Extreme Ambient Temperature Resilience
Specifically thermal-tailored to operate securely within the enclosed, high-heat compartments of modern air compressors. The entire motor assembly maintains peak mechanical integrity even when the local internal ambient temperature reaches its maximum limit of +46°C.
Targeted Applications in Atlas Copco Systems
With its high-velocity 2-pole configuration and 5.5 kW power profile, the 1091631955 motor fulfills critical roles within factory-certified Atlas Copco equipment configurations:
Primary Drive Units
Serves as the dedicated main power source for specific mid-range stationary rotary screw air compressors, ensuring constant torque and reliable air displacement.
High-Capacity Ventilation Systems
Utilized in larger compressor systems as the independent heavy-duty cooling fan drive, maintaining optimal heat exchange parameters for the entire compressed air circuit.
FAQ
1
How can I verify that this 1091631955 motor is an authentic Atlas Copco part?
Every genuine unit features the unique Atlas Copco part number 1091631955 deeply integrated into its factory documentation. To ensure absolute verification and compatibility for your specific compressor installation, please provide your machine’s official serial number (found on the compressor data plate) to our technical support team for precise bill-of-materials validation.
2
The nameplate indicates "Marathon Motors." Does this mean it is a genuine Atlas Copco part?
Yes, absolutely. Atlas Copco collaborates with premium global specialized manufacturers to produce heavy-duty components engineered precisely to Atlas Copco’s proprietary, confidential specifications. The 1091631955 motor is a factory-certified, original equipment component built exclusively for Atlas Copco air systems. It possesses proprietary shaft tolerances, customized bearing clearances, and specialized winding protections that standard off-the-shelf industrial motors cannot replicate.
3
What are the operational risks of utilizing non-original motors in my system?
Non-original motors lack the precise IM B34 alignment constraints, matching power factors, and specialized C3 clearance bearings required to handle the persistent thermal load of a compressor housing. Utilizing authentic parts eliminates premature bearing failure, prevents catastrophic coupling misalignment, and secures your system’s operational warranty and uptime integrity.
Procurement and Technical Validation
Securing authentic equipment is the most effective strategy to prevent unexpected downtime and protect your high-value production assets. To ensure a seamless installation process, our technical specialists are available to perform a comprehensive compatibility review. Prior to finalizing your maintenance order, please prepare your compressor model designation and system serial number to ensure immediate, factory-accurate validation.
