Atlas Copco 1623770651 Electric Drive Motor Screw Compressor Spare Parts
Genuine Atlas Copco 1623770651 electric drive motors deliver reliable mechanical power transmission and continuous-duty performance for industrial rotary screw air compressors.
Industrial air compressor drive motors operate under continuous heavy torque loads, severe thermal cycling, and high ambient factory temperatures. The 1623770651 drive motor is engineered specifically to match the torque absorption characteristics and starting duty cycles of Atlas Copco screw compressor elements.
Using non-genuine or rewound electric motors with uncalibrated torque curves leads to electrical phase imbalance, excessive winding temperatures, and premature stator insulation failure. Genuine Atlas Copco motors preserve the original electrical and mechanical design intent of your compressor package.
- Dynamically balanced rotor assembly — precision balancing minimizes operational vibration, preventing harmonic vibrations from transmitting through the drive coupling into precision air end bearings.
- High-grade copper stator windings — Class F or Class H electrical insulation systems treated with advanced vacuum pressure impregnation to resist moisture and airborne oil mist.
- Heavy-duty DE and NDE bearings — pre-lubricated with high-temperature industrial synthetic grease engineered for continuous high-speed rotation.
- Integrated thermal protection sensors — embedded inside the stator windings and connected directly to the Elektronikon controller to trigger automatic shutdown before damaging thermal overloads occur.
- Precision-machined mounting flanges and drive shaft — tolerances ensure concentric alignment with compressor gearboxes or flexible drive couplings, eliminating radial shaft runout.
- Export-grade packaging — every motor unit is secured in heavy-duty wooden shipping crates with shaft-locking fixtures to prevent bearing brinelling during international sea freight transport.
Please provide your compressor model designation, machine serial number, site voltage, and operational frequency from the motor nameplate to verify electrical specifications and check availability.

Mechanical binding in the air end, voltage drop in plant wiring, or degraded stator insulation increases amperage draw, requiring resistance and mechanical load testing.
Shaft misalignment exerts excessive radial and axial loads that cause rapid bearing failure, coupling wear, and elevated operating temperatures.
Under-greasing causes rapid friction wear, while over-greasing causes thermal churning, both requiring strict adherence to nameplate grease specs and intervals.
