Nidec-US Motors 2203 Motor

The Nidec-US Motors 2203 Motor is a high-performance 1HP condenser fan motor engineered for demanding commercial HVACR environments. Operating at 1075 RPM, this dual voltage motor supports 208-230/460Vac configurations, making it a versatile choice for field replacements on multi-voltage systems. Built on a 56Z frame size with a 5/8" diameter flat shaft, this unit provides the structural rigidity required for high-torque fan applications. It utilizes a permanent split capacitor (PSC) design to maintain high efficiency and reliability under continuous heavy-duty cycles.

For technicians performing maintenance or emergency repairs, the Nidec 2203 is a direct 917291 cross reference, ensuring seamless drop-in compatibility. The TEAO (Totally Enclosed Air Over) enclosure protects internal components from debris while leveraging the system's airflow for cooling. With reversible rotation capability and ball bearings designed for multi-angle mounting, this reversible condenser motor adapts to various shroud and fan blade configurations without compromising performance.

• Dual Voltage Versatility: Direct support for 208-230/460V power supplies simplifies inventory and on-site wiring.
• Robust Construction: Features double-sealed ball bearings and Class B insulation for extended life in high-ambient 60°C conditions.
• Flexible Mounting: Equipped with a hub or stud mount design and a 56Z frame for secure installation in diverse condenser units.
• Built-In Protection: Integrated automatic reset thermal overload protector prevents motor burnout during extreme operating conditions.

Can I use this motor to replace an 825 RPM unit?
No. While many 1075 RPM motors are interchangeable, you must match the design RPM of the existing fan blade to avoid overloading the motor or disrupting critical airflow across the coils.

Is this motor suitable for outdoor use?
Yes, the TEAO enclosure is specifically designed for outdoor condenser applications where the motor is exposed to the elements but cooled by the fan's airflow.

How do I change the motor rotation?
The reversible rotation is typically handled via the Lead connectors; refer to the nameplate wiring diagram to switch between CW and CCW rotations to match your fan blade pitch.
