Rheem-Ruud 51-100344-01 Blower Motor

The Rheem-Ruud 51-100344-01 Blower Motor is a high-efficiency Direct Drive Blower Motor engineered for precise performance in OEM HVAC replacement applications. This 1/6 HP 825 RPM Motor operates on a 208-230V single phase power supply, drawing a steady 1.6 Amps. Featuring a 48 Nema Frame and an Open Air Over (OAO) enclosure, this Permanent Split Capacitor (PSC) motor utilizes sleeve bearings for quiet operation and longevity. Designed with a 1/2" x 2 5/8" shaft and CCW rotation, it integrates seamlessly via shell-band or shell-screw mounting. This two-speed blower motor is a critical component for maintaining system static pressure and ensuring consistent airflow across the heat exchanger. Technicians routinely specify this Rheem replacement part for its reliability in residential air handlers and furnaces where high-efficiency HVAC motors are required to meet strict performance curves without premature failure.

Key Benefits

• Broad Compatibility: Genuine Protecht replacement part tailored for Rheem, Ruud, and WeatherKing equipment.
• Optimized Airflow: Two-speed functionality allows for specialized tuning of CFM based on system demand.
• Durable Construction: The Sleeve Bearing design reduces vibrational noise while the OAO enclosure ensures adequate cooling during high-duty cycles.
• Standardized Fit: Features a 48 Frame diameter and a versatile 1/2-inch shaft width for standard squirrel cage blowers.

Common Questions

What capacitor is required for the 51-100344-01?
This PSC motor typically requires a 5 MFD / 370V run capacitor for proper torque and amperage draw.

Can I use this motor to replace a 1075 RPM model?
No, this is an 825 RPM motor. Replacing a higher-speed motor with this unit will reduce airflow and may lead to evaporator coil freeze-ups or heat exchanger overheating.

Is this motor reversible?
No, this specific model is factory-set for Counter-Clockwise (CCW) rotation as viewed from the lead end.
