Nidec-US Motors 1125 Motor
The Nidec-US Motors 1125 is a professional-grade 3/4 HP direct drive blower motor engineered for high-static residential and commercial furnace applications. Operating at 115Vac with a 900 RPM rated speed, this 4-speed Permanent Split Capacitor (PSC) motor allows for precise airflow adjustment to meet specific HVAC system requirements. Built on a 48Y NEMA frame size with an Open Air Over (OAO) enclosure, it utilizes self-aligning ball bearings to ensure reliable operation in high-ambient temperature environments common in blower compartments. With a 11.9 Amp draw and CCW lead end rotation, this motor provides the torque necessary for heavy-duty cycling. The 1/2" diameter shaft accommodates standard blower wheels, making it a versatile HVAC replacement motor for contractors managing service calls that require immediate, high-torque performance and multi-speed flexibility.
- 4-Speed Versatility: Multiple speed taps allow for customized CFM delivery across heating and cooling stages.
- Self-Aligning Ball Bearings: Designed for durability and reduced friction in vertical or horizontal mounting positions.
- Direct Drive Efficiency: Eliminates belt maintenance while providing consistent 900 RPM performance for better system static pressure management.
- Standardized Housing: The 48Y frame and 1/2" shaft ensure broad compatibility with existing blower assemblies and mounting brackets.
- Thermal Protection: The OAO enclosure design facilitates maximum heat dissipation during continuous duty cycles.
Common Questions
Is this motor constant torque or constant volume?
The 1125 is a standard PSC motor, not an ECM. It provides constant torque based on the selected speed tap and is intended for systems where a traditional capacitor-run motor is specified.
Can I change the rotation of this motor?
This specific model is configured for CCW (Counter-Clockwise) rotation from the lead end. Always verify your blower wheel pitch before installation to ensure proper airflow direction.
What size capacitor does the Nidec 1125 require?
As a PSC motor, it requires a specific run capacitor (typically 15-20 MFD at 370V, though you should verify the rating on the motor nameplate) to ensure proper starting torque and efficiency.
