Nidec-US Motors 7914P Motor

The Nidec-US Motors 7914P Motor is a high-performance three-phase blower motor engineered for commercial HVAC applications. As the direct replaces 23G40 and updated version of 7914, this 2 HP unit provides 1725 RPM for consistent airflow in belt-drive blower systems. Built with a 56 NEMA frame size and a robust open dripproof (ODP) enclosure, it ensures cool operation by allowing air circulation while protecting internal components from falling moisture. Designed for versatility, this motor supports dual voltage configurations of 200-230/460Vac and features reversible rotation to suit various system layouts. It incorporates automatic reset thermal overload protection and Class B insulation for reliable service in 40°C ambient environments. The rigid base mount and 7/8" shaft diameter make it a standard drop-in solution for contractors performing maintenance on commercial air conditioning and heating equipment.

• Interchangeable Compatibility: Directly replaces the Lennox 23G40 and Nidec 7914 models, reducing downtime during field replacements.
• Commercial Grade Durability: Features double contact sealed ball bearings and a 1.15 service factor for continuous duty performance.
• Application Flexibility: Supporting multiple voltages and reversible rotation makes it an essential stock item for three-phase commercial HVAC service.
• Thermal Security: Integrated automatic overload protector prevents motor burnout during high-demand cycles or restricted airflow.

Can the rotation direction be field-adjusted?
Yes, this is a reversible motor. Rotation can be changed by following the wiring diagram on the nameplate to ensure compatibility with your specific blower wheel configuration.

What are the wiring requirements for the 200-230/460V range?
This motor utilizes a standard nine-lead configuration for three-phase power. Ensure lead connections (T1-T9) are properly combined and insulated per the high or low voltage setting required by your site power.

Does the 56HZ frame fit standard 56-frame rigid mounts?
The 56HZ frame typically features a slightly different shaft height or mounting hole pattern than a standard 56 frame; always verify the NEMA dimension print before installation to ensure bolt-hole alignment.
