Nidec-US Motors 4749 Motor
The Nidec-US Motors 4749 Motor is a professional-grade 1/2 HP condenser fan motor engineered for demanding direct-drive ventilation and HVACR applications. Operating at a synchronous speed of 1100 RPM, this single-phase motor features a dual-voltage 115/230V configuration, making it a versatile drop-in replacement for various OEM condenser fan units. Built with an Open Air Over (OAO) enclosure, it relies on the system’s airflow for thermal management, ensuring stable performance during continuous duty cycles. The 5.6-inch diameter housing and 48Y frame (often designated as 48YZ) utilize a stud mount design for secure installation. With ball bearings and automatic thermal overload protection, this motor is designed to withstand 40°C ambient environments. The Permanent Split Capacitor (PSC) design typically requires a 10 MFD 370V capacitor to maintain high efficiency and high starting torque in fractional horsepower electric motor replacements.
Key Benefits- Dual-Voltage Versatility: Field-selectable 115V or 230V wiring accommodates a wide range of residential and commercial HVAC units.
- Enhanced Durability: Equipped with ball bearings and Exxon POLYREX® EM lubricant for reduced friction and extended operational life.
- Reliable Protection: Integrated automatic thermal overload protection prevents winding failure during voltage fluctuations or restricted airflow.
- Industry Standard Fit: Common 5/8" x 3.25" shaft and 5.6" diameter ensure compatibility with most standard fan blades and shrouds.
What capacitor is required for the US Motors 4749?
This motor requires a 10.0 MFD / 370V capacitor for proper operation. It is best practice to install a new capacitor whenever the motor is replaced.
Can the rotation of this motor be changed?
Yes, the 4749 is a reversible motor. The rotation direction is altered by swapping the reversing leads as per the nameplate wiring diagram.
Is this motor suitable for totally enclosed applications?
No, this is an Open Air Over (OAO) motor. It must be mounted within the airstream of the fan it is driving to prevent overheating during continuous operation.
