Nidec-US Motors 4811 Motor
The Nidec US Motors 4811 is a high-performance 1/3 HP condenser fan motor engineered for demanding residential and commercial HVAC applications. Operating at 1625 RPM on 230V single-phase power, this Permanent Split Capacitor (PSC) motor pulls 1.8 Amps and is built around a versatile 48Y NEMA frame. Designed with an Open Air Over (OAO) enclosure, it utilizes the system’s airflow to maintain optimal thermal management during continuous operation. The self-aligning sleeve bearing system and resilient mount configuration significantly reduce vibration and mechanical noise, ensuring stable operation in high-static environments. Featuring a 1/2" diameter shaft and reversible rotation capabilities, the 4811 serves as a highly adaptable HVAC replacement motor. This unit is specifically manufactured to withstand the Rigors of outdoor condenser environments while maintaining high electrical efficiency and torque consistency across its service life.
Key Technical Benefits
- Optimized Cooling: The Open Air Over (OAO) design ensures the motor stays within thermal limits during peak summer loads.
- Vibration Dampening: Integrated resilient mounting and sleeve bearings minimize resonance through the condenser cabinet.
- Field Versatility: Reversible rotation and a standard 1/2 inch shaft allow this unit to replace various OEM configurations.
- Efficient Performance: PSC motor technology provides a reliable start and consistent 1625 RPM output for precise airflow.
- Industrial Build: The 48Y frame construction is industry-standard for durability in high-duty cycle condenser fan motor applications.
Common Installation Questions
What capacitor is required for the US Motors 4811?
This 1/3 HP motor typically requires a 5 MFD / 370V run capacitor; always verify the capacitor rating on the motor nameplate during installation to prevent winding overheating.
Can this motor be mounted at any angle?
The self-aligning sleeve bearings are designed for horizontal or shaft-up/down orientations common in condenser fan units, provided the OAO enclosure receives proper airflow.
How do I change the rotation on the 4811 motor?
Rotation is easily reversed in the field by swapping the two lead wires according to the wiring diagram located on the motor housing.
