Century Motors RB1104AV1 Motor

For contractors requiring a dependable replacement for the C523 or C523V1 motor, the Century Motors RB1104AV1 serves as a high-performance 1 HP belt drive blower motor. This industrial-duty electric motor is engineered with a 56 Nema Frame and a rolled steel construction to withstand continuous operation in demanding HVACR environments. Featuring an Open Drip Proof (ODP) enclosure, it ensures optimal airflow and cooling for internal components while maintaining a 1.25 service factor for overhead capacity. The 5/8" x 1 7/8" keyed shaft and reversible rotation capability provide the versatility needed for various pulley configurations in commercial and residential fan systems. Designed with ball bearings and a resilient base, this capacitor start induction run motor minimizes vibration and noise, making it an ideal choice for persistent furnace and air handler applications. Its 115/208-230 Vac dual voltage rating and automatic reset thermal protection ensure it meets the rigorous technical standards expected by field technicians.

Key Benefits:

• Direct Interchangeability: Seamlessly replaces legacy C523V1 and C523 models without mounting modifications.
• High Starting Torque: Effectively initiates high-inertia belt-driven loads common in large blower assemblies.
• Quiet Operation: The resilient cradle base absorbs mechanical harmonics, reducing cabinet resonance.
• Thermal Safety: Built-in automatic overload protection prevents winding failure during restricted airflow conditions.
• Universal Mounting: Fixed 56-frame base and standard 5/8-inch shaft simplify field installation on diverse HVAC blower motors.
