Liebert 1D19535P2S Motor

As a seasoned technician, you know that maintaining head pressure in Liebert precision cooling systems requires exact OEM specifications. The Liebert 1D19535P2S Motor is a high-performance 277V 1PH condenser fan motor designed specifically for demanding data center and industrial environments. Rated at 1/2 HP with a maximum speed of 1060 RPM, this 2-speed motor provides the critical variable airflow control needed to manage fluctuating heat loads while maintaining tight temperature and humidity tolerances. Engineered for 277-volt single-phase power circuits, this direct-drive motor ensures seamless integration with existing Liebert fan speed controllers and mounting brackets, eliminating the field-modification headaches common with universal alternatives.

When you are troubleshooting a failed Liebert condenser fan, opting for this genuine OEM replacement motor is essential to ensure the fan blade pitch and aerodynamic load match the internal thermal protection and torque profile. Whether you are servicing a Liebert DS, CRV, or Quiet-Line condenser, this 20lb unit provides the mechanical reliability required for 24/7 mission-critical operations. Utilizing the original 1D19535P2S part number ensures that the starting torque and current draw align perfectly with the system's contactors and capacitors, preventing nuisance trips and premature component wear.

• Optimized Performance: Delivering 1/2 HP at 1060 RPM, this two-speed motor provides versatile airflow management for precision cooling applications.
• Application Specific: Designed exclusively for 277V single-phase electrical architectures found in commercial and industrial HVACR deployments.
• OEM Integrity: Authentic Liebert 1D19535P2S construction ensures perfect fitment and maintains the operational integrity of the condenser unit.
• Quiet Operation: Balanced rotor and precise bearing tolerances minimize vibration and structural noise during high-speed operation.

Common Questions

What are the signs that my Liebert condenser fan motor is failing?
Keep an ear out for grinding or squealing noises, which usually indicate worn bearings. If the motor is humming but the blades aren't spinning, or if the system is frequently shutting down due to high-pressure alarms, the motor's internal windings or the associated run capacitor may be compromised.

Can I use a universal 460V motor instead of this 277V model?
No. The 1D19535P2S is specifically wound for 277V 1PH power. Attempting to use a different voltage or phase configuration will damage the motor and potentially the system's controller. Always match the voltage and horsepower ratings exactly to the equipment nameplate.

Does this motor require a specific fan speed controller?
This 2-speed blower motor is designed to interface with Liebert’s standard fan speed controls. If you are replacing a motor after a catastrophic failure, it is best practice to also inspect the fan speed controller and capacitor for signs of electrical stress.
