Nidec-US Motors 4114 Motor

The Nidec-US Motors 4114 is a professional-grade 1/2 HP belt drive blower motor designed for high-static HVAC applications. Engineered with a NEMA 56 frame and a split-phase design, this motor operates at a synchronous 1800 RPM (1725 RPM nameplate) and supports 115/230V dual voltage configurations. Built with a resilient cradle base to dampen vibration and an open drip-proof (ODP) enclosure for maximum airflow, it is the industry-standard replacement for the S1-024-11960-000. The 5/8" diameter shaft and reversible rotation (CW/CCW) ensure cross-compatibility with a wide range of furnace and air handler belt-drive systems. For the service tech, the automatic reset thermal overload protector and self-aligning sleeve bearings provide consistent performance under continuous duty cycles. This 4-pole, single-phase 4114 motor is the definitive solution for restoring airflow in commercial and residential belted fan assemblies.

• Universal Flexibility: Features reversible rotation and 115V/230V dual voltage capability to match diverse field requirements.
• Vibration Isolation: The resilient mount design reduces harmonic noise and mechanical wear in air handling units.
• Direct Cross-Reference: Specifically engineered as the 1/2HP replacement for S1-024-11960-000 and other legacy York/Luxaire motors.
• Thermal Protection: Integrated automatic reset thermal overload prevents winding damage during temporary temperature spikes or locked-rotor conditions.
• NEMA Standard Housing: Built on a durable 56 frame platform with a 5/8" shaft for easy pulley alignment and belt tensioning.

Is the US Motors 4114 reversible in the field?
Yes, this motor features reversible rotation. You can easily switch between clockwise (CW) and counter-clockwise (CCW) rotation by following the lead connection diagram on the nameplate, making it compatible with various blower configurations.

What is the difference between this and the S1-024-11960-000?
The US Motors 4114 is the direct 1/2 HP technical replacement. It matches the original mounting, shaft diameter, and electrical specs while offering the added benefit of dual voltage (115/230Vac) versatility.

Can this motor be used for continuous duty?
Exactly. This is a continuous duty rated HVAC blower motor. Its Open Drip Proof (ODP) enclosure allows for optimal cooling during long run cycles, provided the environment is relatively dry and free of heavy contaminants.
