Daikin-McQuay 057077301 Motor

The Daikin-McQuay 057077301 Motor is a high-performance 3/4 HP condenser fan motor engineered for demanding commercial and industrial HVACR applications. Operating at 208/230V and a nominal 1625 RPM, this PSC (Permanent Split Capacitor) motor is a direct replacement for legacy Daikin and McQuay part numbers, including 57077301 and 105677201. Designed for single-phase power systems, it provides the high torque and consistent thermal dissipation required to move air across the condenser coils effectively. This ensures optimal heat transfer and prevents excessive head pressure in the refrigeration circuit. When replacing a Daikin-McQuay 057077301, verify the frame size and shaft dimensions to ensure a proper fit with existing fan blades. This motor is built to withstand outdoor environments, offering reliability for contractors seeking a 3/4HP 208/230V Cond Fan Motor that maintains system efficiency and protects the compressor from overheating during peak load conditions.

• Precise OEM Compatibility: Specifically designed as a drop-in replacement for McQuay 057077301 and Daikin 057077301 units to eliminate field modifications.
• High-Speed Thermal Performance: Rated at 1625 RPM to maximize airflow and refrigerant cooling efficiency in 208-230V systems.
• Industrial Build Quality: Features durable construction for continuous duty in outdoor condensing units.
• Optimized Energy Consumption: PSC motor design balances high starting torque with efficient operation to reduce utility overhead.
• Reduced System Strain: Consistent fan speeds help prevent liquid slugging and compressor fatigue by maintaining stable condensing temperatures.

• What are the electrical requirements for this motor? This is a 3/4 HP single-phase motor that requires 208-230V power. Always verify your capacitor rating matches the manufacturer's specification for this motor.
• Can this motor replace other 3/4 HP condenser fans? While it is an OEM Daikin-McQuay motor, it can replace other motors with matching RPM, frame, and voltage specifications; however, shaft length and diameter must be confirmed.
• Why is my condenser fan motor humming or failing to start? Common issues include a failed start/run capacitor, debris blocking the fan blades, or internal bearing wear. If the motor is hot to the touch but not spinning, proactive replacement is recommended to avoid compressor damage.
