Marley Engineered Products 490059006 Motor

The Marley Engineered Products 490059006 Motor is a high-performance direct drive blower motor engineered specifically for heavy-duty HVACR applications. As a 1/3HP, 208-230V unit, this permanent split capacitor motor operates at a fixed 1550 RPM, providing the consistent static pressure handling required for Berko and QMark fan-forced heaters. Built by A.O. Smith for Marley, it features a 5-inch diameter frame and resilient sleeve bearings for quiet, long-term operation in commercial environments. This OEM replacement motor includes a 1/2" diameter by 2-1/4" length shaft and requires a 3MFD 370V capacitor for proper phase shifting. For technicians performing an HVAC motor replacement, the Class B insulation and thermal overload protection ensure the unit maintains integrity under high-heat cycles typical of forced-air heating systems. Proper alignment and secure mounting of the 4-5/8" 'A' dimension housing are critical to prevent vibration and premature sleeve bearing wear.

• Optimized Performance: Fixed 1550 RPM speed delivers reliable airflow for specific Marley Engineered Products heating units.
• Industrial Construction: Features a 5-inch diameter motor body with a NEMA-standard 1/2 inch "D" shaft for secure blower wheel attachment.
• Internal Protection: Class B insulation and integrated thermal protection prevent winding failure during restricted airflow conditions.
• Cross-Compatibility: Direct replacement for part numbers DE2H025N, DE2H025, and 490059-006.

What capacitor is required for initialization?
This motor requires a 3 MFD / 370V run capacitor. It is vital to verify the capacitor's microfarad rating before installation to ensure the 1/3HP 208-230V motor starts under load correctly.

Is this motor reversible in the field?
This is a single-speed motor with a factory-set rotation. Always confirm your rotation requirements (CW or CCW from the lead end) against the Marley 490059006 specifications to ensure compatibility with your blower housing.

Can this be used in 115V applications?
No, this unit is strictly rated for 208-230V 60Hz single-phase power. Applying lower voltage will result in torque failure and integrated thermal trip.
