Nidec-US Motors 4750 Motor
Directly replace worn-out blower assemblies with the Nidec-US Motors 4750, a rugged 3/4 HP direct drive blower motor engineered for heavy-duty ventilation performance. This single-phase PSC motor operates at 1100 RPM and features a dual-voltage 115/230V design, providing the versatility needed for various commercial and industrial HVAC applications. Built on a 48Y NEMA frame with a 5/8" diameter shaft, it utilizes ball bearings for reduced friction and a continuous duty rating to handle constant-run cycles without skipping a beat.
Installation is straightforward for contractors thanks to the stud mount configuration and CW lead end rotation. The 4750 is equipped with an open air over (OAO) enclosure, allowing for efficient heat dissipation when mounted in the airstream, while the automatic reset thermal overload protector safeguards the windings against overheating. This motor is a functional cross for common OEM units, including 4HZ71 and K55HXFAA-7594, ensuring you have the right specs on hand for a professional service call.
Key Benefits:
- Industrial Durability: Equipped with double-shielded ball bearings for extended operation in high-cycle ventilation systems.
- Dual Voltage Versatility: Simplified wiring with 115V/230V compatibility, drawing 10.0/5.0 Amps respectively.
- Thermal Safety: Features an automatic reset thermal protector to prevent motor burnout during unexpected load shifts.
- OEM Matching: Standard 48Y frame size and 3.25" shaft length ensure a precise fit for standard blower wheels.
- High Efficiency: A Permanent Split Capacitor (PSC) design provides reliable starting torque and energy-efficient performance.
Common Questions:
Does this motor include the run capacitor?
While typically paired with a 17.5 MFD / 370V capacitor, it is standard practice for technicians to verify the required capacitance on the motor nameplate and install a new capacitor to ensure peak performance.
What is the difference between 48Y and 48YZ frames?
The 48Y frame is a NEMA designation indicating a special mounting or shaft configuration. In the case of the 4750, it signifies the stud mount design and specific shaft dimensions required for direct drive blowers.
Can I use this in an enclosed environment?
The Open Air Over (OAO) rating means this motor relies on the air moving through the blower to stay cool. It must be installed within the airstream of the fan it is driving for proper thermal management.
