International Environmental 70556336 Motor

The International Environmental 70556336 motor is a purpose-built OEM replacement motor designed for high-static IEC fan coil units. Operating at 1/12 HP with a voltage range of 115-127V, this permanent split capacitor (PSC) motor delivers a nameplate 1375 RPM at a full load amperage of 1.4A. Engineered for continuous duty in direct drive blower applications, it features a 42Y frame and an open air-over (OAO) enclosure, ensuring optimal thermal management during high-demand cycles. The counter-clockwise lead end (CCWLE) rotation and resilient base mounting provide a drop-in solution for technicians servicing Vertical Stack (MSY/MMY) and Exposed Modular (MXY) series units. By utilizing a ball bearing system rather than sleeve bearings, this blower motor maintains structural integrity under the mechanical stress common in commercial hydronic HVAC environments.

Key Benefits

• Precision Compatibility: Direct OEM match for IEC 70556336 and Nidec 1211, eliminating the need for field modifications to brackets or wiring.
• Multi-Speed Versatility: Features 3-speeds to allow for precise balancing of static pressure and airflow in diverse duct configurations.
• Efficient Heat Dissipation: The Open Air-Over enclosure design utilizes the system's own airflow to prevent winding overheating in continuous duty cycles.
• Simplified Installation: Comes with a resilient ring mount and integrated capacitor requirements, reducing time spent on the job site.

Common Questions

Is a capacitor included with the 70556336 motor?
Yes, this PSC motor requires a run capacitor for operation, which is typically included or integrated into the OEM assembly to ensure the correct microfarad rating for the 1/12 HP load.

Can this motor replace a 115V single-speed fan coil motor?
This is a 3-speed motor. While it can be wired for single-speed operation, it is specifically designed to support the multi-speed taps found on International Environmental control boards for varying CFM requirements.

What is the shaft diameter and rotation?
The motor features a 1/2-inch diameter shaft and is rated for CCWLE rotation. Always verify the blower wheel orientation before securing the hub to ensure proper airflow direction.
