Nidec-US Motors 1391 Motor
As a veteran tech, you know that keeping a customer's airflow consistent depends on a reliable direct drive blower motor. The Nidec-US Motors 1391 is a workhorse 1/4 HP replacement motor designed for multi-speed applications in residential and commercial furnace and heat pump systems. Because this is a Permanent Split Capacitor (PSC) motor, it delivers high electrical efficiency and smooth startups, which are essential for extending the life of the blower assembly. With a standard 42Y NEMA frame size and an Open Drip Proof (ODP) enclosure, it is purpose-built to handle continuous duty in high-demand environments. The rotation is lead-end reversible, giving you the flexibility to match the existing blower wheel's requirements without carrying extra inventory. This unit also features self-aligning ball bearings and an automatic reset thermal overload protector to prevent winding failure during high-static conditions.
- Multi-Speed Versatility: Features 3-speed operation (1050 RPM base) for precise airflow tuning in various HVAC configurations.
- Universal Mounting: Designed for ring or stud mount setups with a 1/2" shaft to ensure a wide range of bracket compatibility.
- Lead-End Reversibility: Simplifies field installation by allowing reversible rotation to suit specific fan blade or blower wheel directions.
- Durable Construction: Engineered with Class B insulation and an all-angle thrust system for long-term reliability in air-over applications.
Common Questions
What capacitor is required for the US Motors 1391?
This 1/4 HP 208-230V motor typically requires a 7.5 MFD / 370 VAC capacitor. Since the capacitor is not internal, we always recommend verifying the nameplate data and replacing the capacitor during the motor swap to avoid service callbacks.
Can this motor replace a 1075 RPM rated unit?
Yes, this 1050 RPM blower motor is a suitable technical substitute for most 1075 RPM 1/4 HP applications, as the slight difference in synchronous speed is generally within acceptable tolerances for direct-drive centrifugal blowers.
Is the shaft length sufficient for standard blower wheels?
The 1391 comes with a 1/2" diameter shaft that includes a standard flat for secure hub set-screw attachment, making it compatible with most 5-inch diameter motor housings and standard blower hubs.
