Nidec-US Motors 3403 Motor
The Nidec-US Motors 3403 Motor is a high-performance 1/4 HP condenser fan motor engineered for demanding HVACR applications. Operating at 208-230V and a nominal 1100 RPM, this single-phase unit is a reliable OEM replacement motor for various residential and light commercial condensing units, frequently cross-referenced with Carrier HC39GE237 and 5KCP39EGS070S models. Built with a 48Y NEMA frame size and a totally enclosed air over (TEAO) enclosure, it ensures maximum protection against environmental contaminants while utilizing the airflow of the system for cooling. The permanent split capacitor (PSC) design provides efficient operation with a low 1.8 Amp draw, while the self-aligning sleeve bearings allow for consistent performance in continuous duty cycles. Installation is streamlined via the stud mount configuration and a standard 1/2" shaft, featuring CW lead end rotation for precise terminal alignment.
- Optimized Performance: Delivering 1100 RPM at 1/4 HP, this motor provides the necessary torque for heavy-duty fan blades without excessive energy consumption.
- Industrial-Grade Build: The 48Y frame and TEAO enclosure are designed to withstand high-ambient outdoor temperatures up to 40°C.
- Precision Mounting: Standard 1/2" diameter shaft and four-stud mounting pattern ensure compatibility with existing fan shroud assemblies.
- Integrated Protection: Features automatic reset thermal overload protection to prevent winding failure during voltage fluctuations or restricted airflow.
Common Questions
What capacitor is required for the Nidec 3403?
This motor typically requires a 5 MFD / 370V run capacitor to achieve proper phase shift and starting torque. Always check the nameplate before finalizing the wiring.
Can I use this motor to replace an 825 RPM unit?
No, replacing an 825 RPM motor with this 1100 RPM unit may lead to higher static pressure and amp draw, potentially overloading the circuit or tripping the internal thermal protector.
Is this motor reversible?
The 3403 model is specified for Clockwise (CW) rotation from the lead end. Ensure your original fan blade pitch matches this rotation for correct airflow direction.
