MARS 00351 Motor

The MARS 00351 is a high-reliability shaded pole condenser fan motor engineered for demanding HVACR applications. Operating at 115V with a power rating of 25W (alternatively rated up to 35W in specific configurations), this 1500 RPM motor features a clockwise (CW) rotation and a 51-frame size, making it a versatile drop-in for various refrigeration and ventilation systems. Built with a 1/4-inch diameter shaft and cast iron unit bearing construction, the MARS unit bearing motor provides exceptional thermal stability and long-term performance in totally enclosed air-over (TEAO) environments. For technicians handling field repairs, this 115V refrigeration motor uses a 1.4-amp draw and 60 Hz single-phase power to maintain consistent airflow. Its design focuses on heat isolation and internal overload protection, ensuring it survives the high-duty cycles of commercial condensers. Whether you are performing a MARS 00351 cross reference or a fresh installation, this motor connects via 22-inch leads for straightforward integration into existing control circuits.

Key Benefits

• High-Torque Performance: Shaded pole design provides reliable starting torque for condenser and evaporator fans.
• Rugged Construction: Cast iron unit bearings offer superior heat dissipation compared to standard sleeve bearings.
• Simplified Compatibility: Standard 51-frame and 1/4" x 0.425" shaft dimensions match a wide range of OEM specifications.
• Internal Protection: Equipped with thermal overload protection to prevent winding failure during restricted airflow conditions.
• All-Angle Mounting: Designed for versatile installation, including end or side-pad mounting configurations.

Common Questions

Can the MARS 00351 be used in walk-in cooler evaporators?
Yes, its totally enclosed air-over (TEAO) enclosure and unit bearing design make it ideal for the moist, low-temperature environments found in refrigeration evaporators and condensers.

Is the rotation reversible on this specific model?
No, the 00351 is a fixed clockwise (CW) rotation motor. Always verify the fan blade pitch to ensure proper airflow direction before installation.

What are the wiring requirements for this motor?
This is a single-speed 115V motor that includes 22-inch leads for easy connection to the power supply, typically requiring no external capacitor as it is a shaded pole start.
