Atlas Copco 1625461089 Permanent Magnet Motor Technical Profile

The Atlas Copco 1625461089 is a highly specialized, three-phase permanent magnet synchronous motor designed exclusively for integration within high-efficiency variable speed drive air compressors. Engineered to meet the most demanding industrial operational environments, this component delivers exceptional power density, reliable thermal management, and a compact footprint that aligns perfectly with the strict performance standards of Atlas Copco systems.

Key Technical Features and Engineering Advantages

• Premium Interior Permanent Magnet (iPM) Technology: Utilizing high-coercivity permanent magnets integrated into the rotor structure, this motor achieves superior power factor and efficiency ratings across a broad operational speed range compared to standard induction motors.
• Advanced Thermal Sustainability: Built with Class H insulation, the winding configuration is qualified to withstand high continuous operating temperatures up to 180°C, ensuring reliable service life during non-stop heavy-duty operation.
• Rigorous Environment Protection: Rated at IP66, the enclosure guarantees complete protection against dust ingress and powerful water jets, safeguarding internal electrical components in harsh, high-humidity, or dusty manufacturing environments.
• Integrated Drive Design: Developed specifically for direct-drive coupling with the screw compressor element, this specialized design optimizes structural stability and lowers general vibration profiles.

Application and Integration Guidelines

This motor assembly is a 100% factory-original component designed for specific medium-range Atlas Copco variable speed drive (VSD+) oil-injected rotary screw air compressors, such as the GA 22 VSD+ and GA 26 VSD+ series.

Due to the specific electrical parameters of the high-frequency design, which operates between 150 Hz and 217 Hz, this equipment must be paired strictly with the matched factory-installed Neos frequency inverter system. Standard line-start grids or non-compatible variable frequency drives will not support the precise electrical synchronization required for permanent magnet synchronous operations.

During maintenance or replacement procedures, technical teams should ensure that all internal sealing surfaces are completely free of contaminants, and proper alignment procedures are followed to maintain the integrity of the IP66 protection level. Always cross-reference the compressor serial number with the original parts manual to confirm exact part matching before installation.
