Nidec-US Motors 1879 Motor

The Nidec-US Motors 1879 Motor is a heavy-duty, 3/4 HP, 1075 RPM wholesale condenser fan motor engineered for demanding residential and commercial refrigeration and air conditioning applications. operating at 208-230V, this 48Y frame motor features a Totally Enclosed Air Over (TEAO) design and a 60°C (140°F) ambient temperature rating, making it ideal for high-heat rooftop and outdoor environments. This PSC (Permanent Split Capacitor) motor utilizes an all-angle thrust system with sleeve bearings to ensure reliable performance whether mounted horizontally or vertically. As a direct replacement for S1-024-19879-700, it maintains critical OEM specifications to ensure seamless field integration. The unit includes 30-inch leads, extended mounting studs, and a hubless lead end for simplified wiring. With an automatic reset thermal overload protector and reversible rotation via external lead swapping, this Nidec 1879 provides the versatility and durability required by HVAC service contractors for rapid system restoration.

• Universal Mount Versatility: Equipped with an all-angle thrust system and extended studs for flexible mounting in various condenser configurations.
• High Ambient Resilience: Rated for 60°C (140°F) operation, preventing nuisance trips and premature winding failure during peak summer loads.
• Direct OEM Compatibility: Specifically designed to replace the Johnson Controls S1-024-19879-700, ensuring matched shaft dimensions and electrical parameters.
• Enhanced Enclosure Protection: The TEAO housing with drain holes on both ends prevents moisture and debris ingress while allowing for efficient heat dissipation.
• Contractor-Friendly Lead Length: Includes generous 30-inch leads to eliminate the need for field splicing in most standard units.

What capacitor is required for the Nidec 1879 motor?
This motor typically requires a 10 MFD / 370V run capacitor. Always check the nameplate on the specific unit as capacitor requirements may be updated by the manufacturer.

Is this motor reversible in the field?
Yes, the 1879 features reversible rotation. Direction can be changed by swapping the internal connection leads according to the wiring diagram on the motor housing.

Can this replace a motor with a different frame size?
This is a NEMA 48Y frame motor with a 5.6-inch diameter. If your existing bracket is designed for a larger or smaller diameter motor, a mounting adapter or new rain shield may be required for a secure fit.
