Rheem-Ruud 51-42368-02 Motor

The Rheem-Ruud 51-42368-02 Motor is a high-performance 1 HP Three Phase Blower Motor engineered for heavy-duty industrial and commercial HVAC applications. Operating at a synchronous speed of 1725 RPM, this dual voltage blower motor is designed to operate on either 208-230V or 460V systems, providing versatile power options for contractors in the field. Built with a 56 Nema Frame Size and a 5/8" x 2 1/4" keyed shaft, it fits standard belt drive blower assemblies with precision. The ball bearing design ensures reduced friction and heat dissipation, which is critical for continuous operation in high-static environments. Featuring reversible rotation capabilities and a stable platform mount, this unit serves as a critical OEM replacement motor for malfunctioning Rheem-Ruud air handler or rooftop units. With a full load amperage of 2.8 at 230V and 1.4 at 460V, it delivers balanced electrical efficiency across its entire performance range.

Key Benefits

• Multi-Voltage Compatibility: Seamlessly switch between 208-230Vac and 460Vac to match site power requirements.
• Industrial Durability: Equipped with premium ball bearings for extended lifecycle and reliability under load.
• Flexible Rotation: Reversible rotation allows for setup in both clockwise and counter-clockwise duct configurations.
• NEMA 56 Frame: Standard mechanical dimensions facilitate straightforward installation into existing platform mounts.

Common Questions

Is this motor suitable for direct drive or belt drive applications?
This motor is specifically designed for belt drive blower systems, which is common in commercial air handlers requiring precise airflow adjustments via pulley ratios.

Does the 51-42368-02 include a capacitor?
No, this is a three phase motor. Unlike single phase motors, three phase units do not require a start or run capacitor to initiate rotation.

Can this motor handle variable frequency drive (VFD) operation?
While built for 60Hz operation, this motor's insulation class and three phase design make it compatible with VFD controllers for energy-saving air distribution.
