Rectorseal M05222 Unit Bearing Motor 4W 230V Ccw 1550 Rpm

Product Description

The RECTORSEAL M05222 is a unit bearing motor rated at 4 watts maximum output, designed for continuous-duty applications in light commercial and residential HVAC equipment. This single-phase, shaded pole motor runs at 1550 RPM with a usable RPM range of 1350 to 1900 and turns counterclockwise (CCW). The totally enclosed fan-cooled (TEFC) enclosure and cast iron construction provide durability in environments where moisture and debris are a concern. Thermal protection is handled through impedance, eliminating the need for an external overload device. Licensed HVAC technicians and equipment service professionals are the typical installers for this type of unit bearing motor.

Unit bearing motors of this type are commonly found in evaporator coil assemblies, small fan applications, and ventilation equipment in residential and light commercial HVAC systems. The single-speed, CCW rotation configuration suits direct-drive fan and blower applications where a compact, low-wattage motor is required. The TEFC enclosure makes it appropriate for installations in areas with elevated humidity or airborne particulates.

Key Features

• 4-watt maximum output for low-power, continuous-duty fan applications
• Counterclockwise (CCW) rotation at 1550 RPM nominal, with an operating range of 1350 to 1900 RPM
• Single-phase shaded pole motor with single-speed operation
• TEFC enclosure with cast iron construction for durability in demanding environments
• Impedance-based thermal protection built in — no external overload required
• Continuous-duty rated for long-term reliable operation

Compatibility

Designed as an OEM-style replacement unit bearing motor for residential and light commercial HVAC fan and blower applications requiring a single-phase, shaded pole, CCW motor at 1550 RPM.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all power to the equipment before removing or installing the motor. Verify rotation direction and RPM requirements of the application before mounting to ensure the replacement motor matches the original specification. Follow all applicable local codes and manufacturer wiring guidelines during reinstallation.
