Nidec-US Motors 8945 Blower Motor

The Nidec-US Motors 8945 Blower Motor is a high-efficiency 460V 1/3 HP blower motor engineered for direct drive fan and blower applications in commercial HVACR systems. Built on a 48Y NEMA frame, this PSC motor (Permanent Split Capacitor) delivers a reliable 1075 RPM across its two-speed operation, providing the flexibility needed for varying airflow demands. With a low 1.3 Amp draw, it is an ideal energy-saving replacement blower motor for economizer units and continuous duty cycles.

Designed for professional-grade durability, the Nidec 8945 features 6201 ball bearings with an all-angle stud mount configuration, allowing for flexible vertical or horizontal installation. The Open Air Over (OAO) enclosure utilizes system airflow to maintain optimal internal temperatures, preventing premature thermal failure. This direct drive blower motor includes automatic reset thermal overload protection and is reversible to match existing equipment rotation requirements, ensuring a seamless field installation for contractors.

Key Benefits

• Dual-Speed Versatility: The 2-speed blower motor design allows for precise CFM adjustments to match specific air handler requirements.
• Rugged Componentry: Features a high-quality 6201 bearing system and Class B insulation for long-term reliability in demanding environments.
• Flexible Mounting: Equipped with all-angle stud mounting and 2.6-inch diameter hub rings to ensure compatibility with various housing brackets.
• Safety and Protection: Integrated automatic reset thermal overload protector shuts down the motor during over-amp or over-temp conditions to prevent winding damage.

Common Questions

Is this motor compatible with 460V single-phase systems?
Yes, the 8945 is specifically designed for 460Vac single phase power supplies and should not be used with standard residential 115V or 230V circuits.

What capacitor is required for operation?
This PSC motor requires a 370V run capacitor (frequently 5 MFD or 7.5 MFD depending on the specific model variation; check nameplate data before installation).

Can I install this motor in any orientation?
Yes, the all-angle stud mount and ball bearing system allow the motor to be securely mounted at any angle, including shaft-up or shaft-down configurations.
