Century Motors U6430 Motor

The Century Motors U6430 Motor is a high-performance unit heater motor designed for continuous duty in demanding HVACR environments. This 1/15 HP shaded pole motor operates at 115 Volts and a constant speed of 1050 RPM, pulling 3.3 Amps. Built with a 42Y Nema frame size, it features a totally enclosed air over (TEAO) enclosure, ensuring the internal components remain protected from dust and debris while relying on the system's airflow for cooling. As a veteran technician knows, the CCW lead end rotation and the 1/2" x 2 1/2" shaft with a flat are critical for matching the original blower wheel or fan blade configuration. This unit serves as the direct replacement for 40387 models, often found in hanging furnaces and industrial heaters. The inclusion of sleeve bearings and automatic thermal protection ensures reliable operation in 40°C ambient temperatures. Whether you are performing a furnace blower motor replacement or maintaining a shop heater, the U6430 provides the exact physical and electrical footprint required for a seamless swap.

Key Benefits

• Direct Fit Compatibility: Specifically engineered as the U6430 direct replacement for 40387, eliminating the need for mounting bracket modifications.
• Resilient Mounting: Includes resilient mounting rings and extended studs on the shaft end to dampen vibration and reduce audible noise during operation.
• Durable TEAO Design: The totally enclosed air over construction prevents airborne contaminants from entering the motor, extending service life in dirty environments.
• Simplified Installation: Features 36-inch leads and a standard 42 frame diameter (5-inch) for easy integration into existing unit heater housings.
• Reliable Thermal Protection: Equipped with an automatic reset thermal overload protector to prevent winding failure during restricted airflow conditions.

Common Questions

What are the primary applications for the Century U6430?
This motor is primarily used in commercial and residential unit heaters, specifically hanging gas-fired furnaces and industrial blowers requiring a 1/15 HP 115V 1050 RPM drive.

Can this motor be mounted in any orientation?
The U6430 is designed for horizontal mounting to ensure proper lubrication of the sleeve bearings and optimal cooling via the system's airstream.

How do I confirm if this is the correct replacement for my old motor?
Verify that your existing motor is a shaded pole 115V motor with a 3.3 Amp draw, 1050 RPM, and CCWLE rotation. Matching the 1/2" shaft diameter and 42Y frame is essential for compatibility.
