International Environmental 70556301 Motor

When you're replacing a fan coil unit motor in low-profile horizontal or vertical stacked systems, the International Environmental 70556301 is the drop-in OEM motor required to maintain factory performance levels. This 1/30 HP direct drive motor operates at 115V and delivers a nominal 1075 RPM, ensuring it meets the specific static pressure requirements of IEC MPY, MXY, and MUY series units. As a Permanent Split Capacitor (PSC) motor, it requires a 7.5 MFD / 370V run capacitor for optimal torque and energy efficiency. Featuring a 3-speed tap configuration and CCW lead end rotation, this motor is designed for high-cycle applications where quiet operation and thermal protection are non-negotiable. The 6-pole design and ball-bearing construction reduce mechanical wear, making it a reliable service part for technicians managing multi-family or commercial hospitality HVAC assets. By using this genuine IEC replacement motor, you avoid the mounting and shaft alignment issues common with generic aftermarket alternatives.

• Direct OEM Compatibility: Engineered specifically as a 5KCP29DK6010AS substitute, keeping AHRI ratings intact.
• Variable Speed Control: The 3-speed motor leads allow for precise airflow balancing based on ductwork restrictions.
• Industrial Build: Rated as an Open Air Over (OPAO) motor with Class B insulation for consistent thermal management.
• Easy Installation: Standard NEMA 42 frame sizing and 7-inch shaft length ensure a perfect fit in compact blower wheels.

Common Questions

What capacitor is recommended for the 70556301?
This motor is specifically designed to work with a 7.5 MFD 370V/440V run capacitor. Using an incorrect rating can cause overheating or failure of the internal windings.

Will this motor fit other fan coil brands?
While it is an OEM part for International Environmental Corporation (IEC) units like the M*Y03, it can serve as a technical cross-reference for other 115V 1/30HP applications requiring a CCW rotation and a 1/2-inch shaft.

Is this a multi-voltage motor?
No, this is a dedicated 115V single-phase motor. Attempting to wire this into 208V or 277V circuits will result in immediate motor burnout.
