Rectorseal M05444 Ecm Unit Bearing Motor 16W 1850 Rpm

Product Description

The RECTORSEAL M05444 is a 16-watt ECM unit bearing motor designed for continuous-duty HVAC applications. It features a totally enclosed air-over (TEAO) enclosure, making it well suited for direct airflow environments where dust and debris are present. The motor runs on a single phase at a rated speed of 1850 RPM with an operating RPM range of 1350 to 1900. Built-in thermal protection guards the motor against overheating during extended operation. HVAC technicians install this motor in fan coil units and other air-handling assemblies where a compact, energy-efficient ECM is required.

This motor is intended for residential and light commercial HVAC equipment that requires a low-wattage, single-phase ECM unit bearing configuration. Its clockwise rotation and single-speed design make it a straightforward replacement in systems originally equipped with similarly rated unit bearing motors. The TEAO enclosure suits applications where the motor is cooled by the airstream it is driving, such as evaporator fan assemblies and ventilation units. The motor ships with accessories included to support installation.

Key Features

• ECM motor type for improved energy efficiency over standard PSC motors
• 16-watt maximum power draw supports low-energy fan applications
• Rated 1850 RPM with an operating range of 1350 to 1900 RPM
• TEAO enclosure rated for direct airstream cooling environments
• Continuous-duty rating for reliable extended-cycle operation
• Built-in thermal protection prevents overheating damage

Compatibility

Designed as an OEM-style replacement for single-phase ECM unit bearing motors in residential and light commercial HVAC fan assemblies.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all power to the equipment before removing the existing motor or making any wiring connections. Verify that the replacement motor rotation direction matches the original unit before final startup. Follow applicable local mechanical and electrical codes throughout the installation process.
