Century Motors BL6414 Motor

For veteran HVAC contractors, the Century Motors BL6414 is a versatile 5-inch diameter workhorse designed for multi-application direct drive installs. This shaded pole motor features a triple-horsepower rating of 1/5-1/8-1/10 HP, allowing technicians to stock a single unit that services various airflow requirements in furnaces, air handlers, and ventilators. Operating at 115V and 1050 RPM, this motor utilizes a 60Hz single phase configuration with three distinct speeds (6.5/4.0/3.0 Amps) to ensure precise static pressure matching. The 42Y Nema frame is constructed from rolled steel with an Open Air Over (OAO) enclosure, promoting optimal heat dissipation during continuous duty. Engineered with sleeve bearings and a 5.5-inch flat shaft (1/2" diameter), it facilitates counter-clockwise lead end (CCWLE) rotation. This unit is the primary replacement for several common OEM parts, including the Universal Electric 385, Rheem 51-23015-91, and Carrier HC37MA134.

Key Benefits for Contractors:

• Multi-Tap Versatility: The 3-speed, multi-HP design (1/5, 1/8, 1/10) reduces truck stock by covering multiple residential ratings.
• Broad OEM Compatibility: Serves as a direct drop-in for 51-23015-91 and HC37MA134, speeding up emergency furnace repairs.
• Durable Construction: Features automatic thermal protection and a rolled steel 42Y frame for longevity in horizontal mounting positions.
• Smooth Operation: Equipped with sleeve bearings and resilient mounting rings to minimize vibration and audible noise in the ductwork.
• Standardized Fit: The 1/2" x 5 1/2" shaft with a flat surface ensures secure blower wheel attachment without heavy modification.

Common Technical Questions:

What is the rotation direction of the BL6414?
This motor is rated for CCWLE rotation (Counter-Clockwise Lead End), which is critical to verify before installing in direct drive blower assemblies.

Does this motor include mounting hardware?
The unit includes resilient mounting rings and extended through-bolts on the shaft end, though belly band mountings are sold separately if required for your specific air handler.

Can I use this motor to replace a 1/6 HP or 1/4 HP unit?
Since this motor covers 1/5 HP, 1/8 HP, and 1/10 HP, it is an appropriate replacement for 1/6 HP and lower ratings. However, consult the 1050 RPM and 115V specs to ensure it matches the original motor's torque profile.
