Nidec-US Motors 4742 Motor
The Nidec-US Motors 4742 is a high-performance 1/6 HP blower motor designed for direct-drive centrifugal ventilation systems. Operating at 115V and a nominal 1650 RPM, this Permanent Split Capacitor (PSC) motor is engineered for continuous duty in demanding HVACR applications. Built on a 42YZ NEMA frame with a 5.0-inch diameter, it features an Open Air Over (OAO) enclosure to ensure optimal thermal management during operation. The ball bearing construction provides mechanical longevity and supports the 1/2" diameter x 3.25" long shaft, optimized for CW lead end rotation.
For contractors performing field replacements, the 4742 motor includes a 7.5 MFD, 370V capacitor and features an automatic reset thermal overload protector to prevent winding failure during high-static conditions. The stud mount configuration allows for secure installation in various blower housings. Drawing 2.7 full load amps, this single-phase motor serves as a reliable direct drive replacement motor for OEM ventilation units requiring precise airflow at a 1.0 service factor.
- High-efficiency Permanent Split Capacitor (PSC) design for reduced electrical consumption.
- Durable ball bearings suitable for multi-positional mounting and extended service life.
- Integrated automatic thermal overload protection to safeguard against overheating.
- Compact 42YZ frame with a specialized 1/2" x 3.25" shaft for standard blower wheels.
- Open Air Over enclosure design maximizes cooling efficiency in the airstream.
Common Questions
What is the correct rotation for the Nidec 4742?
This motor is specified as CW lead end rotation (Clockwise when viewing the lead end/back of the motor), which typically corresponds to CCW shaft end rotation for standard blower applications.
Does this motor include the run capacitor?
Yes, the Nidec 4742 comes equipped with the required 7.5 MFD capacitor to ensure proper starting torque and efficient running performance.
Can this motor be used in totally enclosed environments?
No, this is an Open Air Over (OAO) motor. It requires the moving air from the blower it is driving to dissipate heat and maintain safe operating temperatures.
