Liebert 127164P1S Motor

The Liebert 127164P1S Motor is an essential OEM component for precision cooling infrastructure, specifically designed for Liebert Challenger and Deluxe System/3 units. This 1/4 HP blower motor operates on 277V single-phase power and features a three-speed configuration (1050/900/700 RPM), allowing technicians to fine-tune airflow volume for optimal sensible cooling capacity. Built with a Permanent Split Capacitor (PSC) design, this direct-drive motor ensures consistent static pressure performance in sensitive data center environments. The 48-frame housing and sleeve bearing system are engineered for continuous duty cycles, minimizing vibration transmission and logistical downtime. When performing a motor replacement, verify the microfarad rating of your existing run capacitor to maintain back-EMF limits and thermal protection. This HVAC blower motor provides the reliable heat rejection performance required for mission-critical climate control.

• OEM Compatibility: Precision-engineered for Liebert 127164P1S applications, ensuring exact fitment in CRAC units.
• Multi-Speed Versatility: Triple-tap leads support 1050, 900, and 700 RPM settings for precise CFM adjustments.
• Industrial Build: Designed for high-ambient temperature data center applications with integrated thermal overload protection.
• Power Efficiency: Optimized 277V operation reduces amp draw compared to standard multi-tap generic motors.

Common Questions

Is the Liebert 127164P1S a direct replacement for 48-frame motors?
Yes, this is a standard 48-frame blower motor with OEM-specific lead lengths and mounting characteristics for Vertiv/Liebert systems.

What capacitor does this motor require?
Technicians should check the motor nameplate; standard PSC motors in this horsepower range typically utilize a 5MFD or 7.5MFD 370V run capacitor.

Why is my motor tripping the thermal overload?
Common causes include restricted airflow, a failing run capacitor, or incorrect voltage tap selection for the specific static pressure of the ductwork.
