International Environmental 70556326 Motor

When you're dealing with a failing fan coil unit, the International Environmental 70556326 Motor is the direct OEM replacement you need to restore system static pressure and airflow. This 42-frame, 277v direct drive motor is specifically engineered for IEC's high-efficiency fan coils, delivering a reliable 1/12 HP and 1150 RPM. As a veteran-grade HVAC blower motor replacement, it features an open-air over (OPAO) enclosure and a refined rolled steel frame with an aluminum flange to combat the corrosion typically found in high-moisture plenum environments. The CCWLE rotation (counter-clockwise lead end) and 1-phase configuration ensure seamless integration with existing housing without the need for field modifications. Technicians prefer this IEC 70556326 fan coil motor because it maintains a consistent 0.69 FLA, providing the stability required for tight industrial and commercial voltage tolerances. Replacing old, high-amp draw motors with this factory-authorized part ensures your unit hits the designed CFM while protecting the downstream control board from transient voltage spikes.

• Direct OEM Fit: Drop-in replacement for International Environmental 70556326, fitting popular CBF, CBY, and CHF fan coil series.
• Industrial Build Quality: Features a rolled steel frame and aluminum flange for superior heat dissipation and mechanical durability.
• Precision Performance: 1150 RPM at 277V optimizes blower wheel efficiency to maintain the lowest wattage per CFM.
• Enhanced Serviceability: Compact 42-frame design with integrated lead ends simplifies wiring in tight service access panels.

Common Questions What are the wiring specifications for the 70556326 motor? This is a 277V, single-phase motor designed for direct-drive fan coil units. It typically utilizes a 5uF/440V capacitor (often included or sold separately) to maintain proper torque and starting current. Always check the lead wire color codes on the nameplate as they are specific to the International Environmental factory standards. Does this motor support variable speed or is it single-speed? The IEC 70556326 motor is a constant-torque, single-speed direct drive motor. While it is engineered to handle the varying intensities of HVAC cycles, it is not a variable frequency drive (VFD) component. What causes premature failure in these fan coil motors? The most common issues are bearing wear from excessive vibration and winding overheating due to dirty air filters or blocked blower wheels. Replacing the motor with a genuine 70556326 blower motor restores the original thermal protection and insulation class B ratings required for long-term operational reliability.
