Genuine Atlas Copco Air Compressor Main Motor 2205269508 Marathon HGMT1 132M3-2

In industrial compressed air systems, the main drive motor is the heart of the entire operation. Ensuring the continuous, efficient, and safe operation of your air plant requires uncompromising component integrity. The Genuine Atlas Copco Main Motor (Part Number: 2205269508), manufactured by Marathon Motors, is engineered specifically to meet the rigorous demand cycles of heavy-duty rotary screw compressors.

As a factory-original replacement part, this 15 kW high-efficiency motor guarantees a seamless drop-in fit, restoring your equipment to its exact original factory specifications without the risks associated with third-party modifications.

Key Features and Engineering Advantages

• High Power Density Configuration: Engineered into a compact 132M frame size, this motor delivers a robust 15 kW output. This specialized high-power-density design provides the optimal torque-to-size ratio required by high-performance industrial compressors.
• Enhanced Thermal Tolerance: Unlike standard industrial motors limited to a 40°C ambient threshold, this authentic component features a rated ambient temperature limit of +46°C. This ensures stable, continuous operation even in confined, high-temperature compressor canopies.
• Heavy-Duty Bearing Architecture: Equipped with premium 6308-2Z/C3 deep groove ball bearings on both the drive end (DE) and non-drive end (NDE). The C3 internal clearance and dual-shielding provide superior axial and radial load capacity, effectively extending the service intervals of the powertrain.
• Optimized Service Factor (SF): With a service factor of 1.15, the motor possesses a built-in 15% operational reserve, allowing it to withstand transient overloads and voltage fluctuations without risking insulation degradation.

Equipment Compatibility & Application

The 2205269508 main motor is tailored for industrial rotary screw air compressor environments. It operates under a strict S1 continuous duty cycle, meaning it is designed to run non-stop at its full rated capacity. The dual IM B35 mounting mechanism offers integrated rigid feet and a precise front-end flange, which aligns perfectly with the standard compressor air-end bell housings used by Atlas Copco.

Frequently Asked Questions (FAQ)

Q1: Is this motor an aftermarket replication or a genuine component?

A: This is a 100% genuine and authentic factory-original component. It is built by Marathon Motors strictly to the engineering specifications required for Atlas Copco compressed air systems, corresponding directly to part number 2205269508.

Q2: Why is the B35 mounting profile critical for replacement?

A: The IM B35 profile provides dual-anchoring. It includes both physical feet to mount onto the compressor chassis and a machined flange interface to bolt directly to the air-end. Utilizing a genuine B35 profile ensures perfect alignment, preventing coupling wear and vibration issues.

Q3: Can this motor operate reliably in unventilated or warm environments?

A: Yes. While generic motors are rated up to 40°C, this authentic replacement part is rated for ambient environments up to +46°C with Class F thermal insulation. It is specifically built to handle the enclosed, high-heat internal climates typical of industrial air compressor cabinets.

Q4: How can I verify that this part matches my system?

A: To ensure absolute compatibility, cross-reference the part number 2205269508 within your compressor’s official parts manual, or verify that your current motor features the HGMT1 132M3-2 designation on its nameplate.
