Rectorseal M00661 Unit Bearing Motor 9W 1550 Rpm

Product Description

The RECTORSEAL M00661 is a shaded pole unit bearing motor designed as a direct OEM-style replacement for the Tyler 52434980. It runs on a single-phase circuit and delivers up to 9 watts of output at a nominal speed of 1550 RPM, with an operating range spanning 1350 to 1900 RPM. The motor uses a sleeve bearing construction and is housed in a totally enclosed fan-cooled (TEFC) enclosure for reliable performance in refrigerated display case and commercial refrigeration applications. Automatic thermal protection is built in, providing a layer of safeguard against overheating without manual reset requirements. Licensed refrigeration technicians and commercial HVAC-R service pros are the typical installers.

This unit bearing motor is suited for commercial refrigeration equipment, including open and closed refrigerated display cases where the Tyler 52434980 was originally installed. Single-speed, clockwise-rotation operation makes it a straightforward drop-in replacement in reach-in coolers, multi-deck cases, and similar evaporator fan applications. The sleeve bearing design is well matched to the low-noise, continuous-duty demands typical of retail refrigeration environments.

Key Features

• Sleeve bearing construction for quiet, continuous-duty operation
• TEFC enclosure protects internal windings in damp refrigerated environments
• Shaded pole, single-phase motor — no run capacitor required
• Automatic thermal protection resets without manual intervention
• Fixed clockwise rotation at a nominal 1550 RPM (range: 1350-1900 RPM)
• Direct replacement for Tyler 52434980

Compatibility

Specified as a direct replacement for Tyler part number 52434980. Suitable for use in commercial refrigerated display case evaporator fan assemblies where the original Tyler motor was factory installed.

Installation Notes

Installation should be performed by a qualified refrigeration or HVAC-R technician. Disconnect and lock out all power to the refrigeration unit before removing the existing motor. Confirm rotation direction and shaft size match the original assembly before completing the installation. Follow applicable local codes and the equipment manufacturer's service documentation when replacing evaporator fan motors in commercial refrigeration systems.
