Rectorseal M05443 Ecm Unit Bearing Motor 9W Single Phase

Product Description

The RECTORSEAL M05443 is a 9-watt ECM unit bearing motor designed for continuous-duty operation in HVAC applications. It runs on single-phase power with a fixed speed of 1650 RPM and an operating range of 1350 to 1900 RPM. The motor features a TEAO (Totally Enclosed Air Over) enclosure, making it suited for direct airflow cooling as found in fan coil units and small air handlers. Clockwise rotation and built-in thermal protection are standard. Licensed HVAC technicians handle installation as part of blower or fan assembly service.

This motor is typically installed in residential and light commercial fan coil units, unit ventilators, and similar forced-air equipment where a compact, energy-efficient ECM replaces a failed or underperforming unit bearing motor. The accessory kit included with the M05443 supports a straightforward swap in common unit bearing motor applications. Single-speed operation simplifies wiring and commissioning compared to multi-speed alternatives.

Key Features

• ECM motor technology for improved efficiency over PSC designs
• TEAO enclosure rated for direct air-over cooling environments
• Continuous duty rating for uninterrupted operation
• Built-in thermal protection guards against overtemperature conditions
• 1350 to 1900 RPM operating range with nominal 1650 RPM
• Includes accessory kit for installation

Compatibility

Designed as an OEM-style replacement unit bearing ECM motor for residential and light commercial fan coil and air-handling equipment requiring a single-phase, 9-watt continuous-duty motor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the air handler or fan coil unit before removing the existing motor. Verify rotation direction and RPM range match the application requirements before energizing. Follow local electrical codes and the equipment manufacturer's service instructions during reassembly.
