Nidec-US Motors 1790 Motor
The Nidec-US Motors 1790 is a heavy-duty, 1/2 HP blower motor engineered for high-static residential and commercial HVAC applications. Operating at a nominal 1725 RPM, this split-phase motor supports dual-voltage configurations of 115/208-230Vac, pulling 9.2/4.6 Amps respectively. Built on a standard 56 NEMA frame with a 5/8" diameter shaft, it features a resilient mount (cradle base) to effectively dampen vibration and minimize noise transfer through the ductwork. The Open Drip Proof (ODP) enclosure is designed for clean, dry indoor environments, ensuring optimal airflow over the internal windings. This model utilizes self-aligning ball bearings to handle radial loads and maintain shaft alignment throughout the duty cycle. With reversible rotation capabilities, it serves as a versatile HVAC replacement motor for various belt-drive blowers and fans requiring precise torque and long-term reliability.
- Dual-Voltage Versatility: Seamlessly integrates into 115V or 230V systems for broader field compatibility.
- Vibration Isolation: The resilient base mount reduces harmonic resonance during startup and high-speed operation.
- Reversible Lead Wires: Allows for easy field adjustment of rotation to match the blower wheel configuration.
- Heavy-Duty Bearings: Self-aligning ball bearings extend the service life of the motor under continuous load.
- Standardized 56 Frame: Simplifies drop-in replacement for worn-out OEM motors in existing belt-drive assemblies.
Common Questions
Can this motor be used in a direct-drive application?
This motor is specifically designed for belt-drive systems using a 56-frame cradle mount. Ensure the blower pulley is properly keyed to the 5/8" shaft for optimal torque transmission.
How do I change the rotation of the 1790 motor?
The unit features interchangeable leads within the connection box. To change from CCW to CW, follow the wiring schematic on the nameplate to swap the specified motor leads.
Is the 1790 suitable for damp or outdoor environments?
As an Open Drip Proof (ODP) motor, it should only be installed in protected, indoor locations where it is shielded from direct moisture and environmental debris.
