Nidec-US Motors 3404 Motor
The Nidec US Motors 3404 is a professional-grade 1/4 HP condenser fan motor engineered for rigorous residential and commercial HVACR applications. Operating on 208-230V single-phase power at 1100 RPM, this Permanent Split Capacitor (PSC) motor is a drop-in replacement for many 48Y NEMA frame systems, including specific Carrier and Bryant units. As an OEM direct replacement motor, it features a Totally Enclosed Air Over (TEAO) enclosure with drain holes at both ends to prevent moisture buildup in vertical applications. The 5.6-inch diameter body and stud mount design ensure a secure fit, while the all-angle sleeve bearing system with self-aligning thrust allows for versatile installation positions. Designed with a 1.8-amp draw and Class B insulation, this motor is rated for 140°F (60°C) ambient temperatures, ensuring reliable heat dissipation and sustained performance under heavy thermal loads.
Key Benefits:
- Optimized Compatibility: Standard 48Y NEMA frame and 1/2-inch shaft make it an ideal HVAC replacement motor for major OEM condensing units.
- Industrial Durability: The TEAO enclosure and automatic thermal overload protection prevent premature burnout caused by environmental debris or voltage fluctuations.
- Service Versatility: Equipped with extended studs and a reversible rotation capability (CW rotation from lead end), adapting easily to various mounting brackets.
- Efficient Heat Transfer: High-ambient design handles the extreme temperatures often found in outdoor condensers, maintaining system head pressure limits.
Common Questions:
Does the US Motors 3404 include the capacitor?
This 1/4 HP 1100 RPM motor typically requires a 5 MFD / 370V capacitor for operation. Always verify the rating on the nameplate when installing to ensure the PSC circuit functions correctly.
Can this motor be mounted in any direction?
Yes, the self-aligning sleeve bearings utilize an all-angle thrust system, allowing for shaft-up or shaft-down installation common in condenser units.
What is the rotation direction of the 3404?
The model 3404 is factory-set for Clockwise (CW) rotation from the lead end (CWLE), but many Nidec-US Motors models in this series offer lead-reversibility for CCW applications.
