Nidec-US Motors D34B2N9 Motor

The Nidec-US Motors D34B2N9 is a heavy-duty, 3/4 HP general purpose motor designed for reliable performance in commercial and industrial HVACR applications. Built on a 56 NEMA frame size, this split phase motor operates at a consistent 1725 RPM on a 115Vac power supply, drawing 11.3 Amps at full load. Its Open Dripproof (ODP) enclosure ensures optimal airflow for cooling while protecting internal components from overhead moisture, making it ideal for relatively clean indoor environments. To mitigate vibration transfer in air-handling units and pumps, this model features a resilient mount coupled with high-grade ball bearings for extended mechanical life and smooth operation. The CCW lead end rotation and standard keyed shaft allow for straightforward integration into existing belt-drive or direct-coupled systems. This single-speed induction motor is engineered for high starting torque, providing the necessary mechanical force to handle demanding HVAC motor replacement tasks without overheating or premature failure.

Key Benefits

• Resilient Base Mount: Specifically engineered to isolate vibration and reduce decibel levels in noise-sensitive ductwork.
• High-Grade Ball Bearings: Provides superior radial load support and minimizes friction compared to standard sleeve bearings.
• Standard 56 Frame: Ensures a seamless drop-in fit for thousands of commercial ventilation and pumping applications.
• Optimized Cooling: The ODP design facilitates maximum heat dissipation to maintain winding integrity during continuous duty cycles.

Common Questions

Is the D34B2N9 suitable for outdoor use?
This motor features an Open Dripproof enclosure, which is rated for indoor environments or protected areas. For direct exposure to rain or heavy debris, a Totally Enclosed Fan Cooled (TEFC) motor is recommended.

What is the direction of rotation for this motor?
The D34B2N9 is configured for Counter-Clockwise (CCW) rotation when viewed from the lead end (opposite the drive end).

Can this motor be used with a Variable Frequency Drive (VFD)?
As a split phase, single-voltage 115V motor, this unit is designed for constant speed operation. Speed control should be verified against specific HVAC controller compatibility.
