The Dayton 1TDP6 is a direct-replacement shaded-pole blower motor designed for HVAC, refrigeration, and ventilation equipment operating on 230V power. With 133 CFM of airflow, ball bearing construction for long service life, and automatic overload protection, this motor is a reliable drop-in for failed or aging units in both residential and light commercial applications.
This motor ships as a direct replacement for Dayton models 2C915 and 1TDP6A. It is also cataloged under NBK Parts number 20497. If your existing unit carries either of those part numbers, the 1TDP6 installs without modification -- same flange dimensions, same shaft size, same rotation direction.
Clockwise shaft rotation and a 5-1/8 in x 4 in mounting flange make fitment straightforward. The 8 mm shaft diameter is a common standard for this motor class, compatible with most OEM blower wheels in the 3-3/4 in diameter range.
Precision ball bearings on both ends support longer service intervals and quieter operation compared to sleeve-bearing alternatives, especially in continuous-duty applications.
Built-in thermal overload protector shuts the motor down if it overheats and automatically resets, protecting against winding damage from blocked airflow or voltage spikes.
Rated for both 50 Hz and 60 Hz power supplies. The two-speed RPM listing (2670 RPM at 50 Hz, 2880 RPM at 60 Hz) reflects this dual-frequency design -- no rewiring required.
Class B winding insulation is rated to 130 deg C, providing a meaningful thermal margin above the 104 deg F (40 deg C) maximum inlet air temperature spec for reliable long-term operation.
The 1TDP6 turns clockwise when viewed from the inlet side. This is important when ordering a replacement -- installing a motor with the wrong rotation direction reverses airflow and dramatically reduces CFM output. Confirm your existing motor's rotation before ordering.
