Nidec-US Motors 1901 Motor

The Nidec-US Motors 1901 motor is a purpose-built condenser fan motor engineered for efficiency and long-term durability in residential cooling applications. Operating at 1075 RPM with a 1/6 HP rating, this 208-230V replacement motor provides the reliable torque necessary to maintain optimal airflow across your condenser coils. As a veteran-grade HVACR motor, it features a 42 NEMA frame size and a totally enclosed air over (TEAO) enclosure, shielding internal components from environmental debris and moisture during continuous operation. This unit serves as the direct drop-in replacement for the 1052659 condenser motor, ensuring your setup maintains original equipment performance without the need for extensive field modifications.

Designed for versatile installation, the Nidec 1901 includes a 1/2" diameter shaft and reversible rotation capabilities, allowing it to adapt to various fan blade pitches found in the field. The permanent split capacitor (PSC) design ensures high energy efficiency and a simplified electrical footprint. To protect the windings from thermal stress, the motor is equipped with an automatic reset thermal overload protector. Utilizing self-aligning sleeve bearings, this motor offers quiet, vibration-resistant performance, which is essential for maintaining suburban noise standards in residential neighborhoods. Note that while this is a direct mechanical replacement, the original connector is not included, requiring field-wiring to the existing harness.

Key Benefits

• Direct Cross-Reference: Engineered as a precise replacement for the 1052659 motor, reducing downtime during emergency service calls.
• High Durability: The TEAO enclosure and Class B insulation protect the motor from high ambient temperatures and wind-driven rain.
• Field Versatility: Features reversible rotation and stud mount configuration to accommodate various condenser unit designs.
• Reliable Bearings: Heavy-duty self-aligning sleeve bearings are designed for vertical shaft-up or shaft-down installations.
• Overload Protection: Integrated automatic reset thermal overload prevents motor burnout during high-pressure cycles or blocked airflow conditions.

Common Questions

Does this motor include the run capacitor?
The motor requires a 5 MFD / 370V capacitor for operation. While most PSC motor replacements require a new capacitor to ensure proper phase shift and torque, check your specific packaging as the 1901 is often sold as the motor unit only.

How do I reverse the rotation on the Nidec 1901?
Rotation is easily reversed by swapping the two leads in the reversing plug located on the side of the motor or within the lead assembly, following the wiring diagram on the nameplate.

Can I use this to replace a 1075 RPM motor with a different horsepower?
It is critical to match the 1/6 HP rating. Using a lower HP motor will cause overheating and premature failure, while a higher HP motor may not operate at peak efficiency for the existing fan blade pitch.
