Nidec-US Motors 4745 Motor
The Nidec-US Motors 4745 is a high-performance 1/3 HP blower motor engineered for demanding direct drive ventilation and HVAC blower motor replacement applications. Operating at 115V and a nominal 1650 RPM, this Permanent Split Capacitor (PSC) motor delivers the torque necessary for efficient air movement in residential and light commercial systems. It features a 5.0-inch diameter frame (NEMA 48YZ) with a versatile reversible rotation capability, allowing for seamless integration into various air handler and furnace configurations. Built for longevity, the 4745 utilizes ball bearings and includes an automatic reset thermal overload protector to prevent winding failure during high-static conditions and 40°C ambient temperatures. This single-speed unit comes with a factory-mounted 6.0 MFD capacitor and a 1/2" x 3.25" shaft, meeting strict OEM specifications for precise fitment and reduced operational vibration in forced air systems.
Key Benefits
- Optimized Performance: Delivers a consistent 1650 RPM output, ensuring stable airflow across heat exchangers and coils.
- Extended Service Life: Heavy-duty ball bearings and continuous duty rating minimize friction and heat-related wear.
- Versatile Compatibility: The reversible rotation and 48YZ frame allow it to replace multiple OEM part numbers in various 115V blower assemblies.
- Integrated Safety: Features automatic overload protection to safeguard the motor from electrical surges or mechanical binding.
- Easy Installation: Includes the required 6.0 MFD capacitor and pre-installed leads for simplified field wiring.
Common Questions
Is this motor compatible with 230V systems?
No, the Nidec 4745 motor is strictly rated for 115V operation. Running this motor on 230V will lead to immediate electrical failure.
What does it mean that the rotation is reversible?
This motor is designed so the lead configuration can be swapped, allowing you to change the shaft rotation direction to match either clockwise or counter-clockwise blower wheels.
Can I use this to replace a 1075 RPM motor?
It is not recommended. Replacing a lower RPM motor with this 1650 RPM unit will significantly increase static pressure and noise, and may overload the motor or damage system components.
