The Carrier 06NA660028 motor and rotor assembly is a precision-engineered replacement component thermal-matched for Carrier Carlyle 06N semi-hermetic screw compressors. This industrial-grade assembly is designed to maintain high volumetric efficiency in medium and high-temperature refrigeration applications. Featuring high-grade stator windings with superior insulation, it ensures reliable performance under the electrical stresses of a refrigerant-cooled motor environment. The balanced rotor assembly minimizes vibration, reducing mechanical wear on the twin-screw profile and extending the service life of the compressor drive system. For contractors performing overhauls or bearing replacements, this kit provides the exact tolerances required to restore factory performance. It is compatible with R-134a, R-404A, and R-507 refrigerants, making it a versatile solution for commercial HVACR systems and process cooling. Proper alignment during installation is critical to prevent premature rotor-to-housing contact and ensure optimal energy efficiency during peak load cycles across applied chiller systems. Key Benefits Oversized Stator Windings: Engineered to provide consistent torque while resisting the corrosive effects of moisture and acid in the refrigeration circuit. Dynamic Balanced Rotor: Reduces axial and radial runout, ensuring smooth power transmission to the compressor screws and lowering decibel levels. Optimized Heat Dissipation: Designed for efficient suction gas cooling, preventing thermal overload during high-discharge pressure conditions. Direct OEM Fit: Eliminates field modifications, ensuring 06N compressor housing compatibility and simplifying the reassembly process. Common Questions Is this motor assembly compatible with all Carlyle 06N models? This assembly is specifically designed for the 06NA660028 configuration. Always verify the compressor model and serial number to ensure the stator displacement and rotor length match your specific frame size. What are the critical steps for installing a new rotor assembly? Ensure that the suction screen is free of debris and that the internal oil passages are clear. Proper alignment with the female and male rotors is essential to prevent mechanical binding during the initial startup. Does this assembly include the discharge check valve or gaskets? This item consists of the stator and rotor components. It is recommended to source a separate compressor gasket kit and inspect the check valve assembly during the teardown to ensure a complete system seal. This item is not eligible for free shipping.
