High Efficiency motors are designed to meet or exceed all EPAct requirements for energy
efficiency as defined by the DOE. The efficiency values are certified according to the DOE’s
regulations (Certificate of Compliance number CC029A).
These Open Drip Proof (ODP) motors are designed for environments where dirt and moisture are
minimal and provide maximum ventilation and heat dissipation. Design B torque and high efficiency
design from 143T through 444/5T frames.
