    To get equipment moving, bolt the base of these motors to any flat surface and connect the shaft to your load. They’re rated for continuous duty, so they’re often used with equipment that requires constant power, like fans, pumps, and conveyors.
    Motors with a NEMA frame size have an oversized shaft and high-quality bearings to stand up to heavy and side loads better than even our domestic motors. Densely packed windings and thin laminations ensure the motor stays cool and runs efficiently.
    Motors with an IEC frame size meet international standards for electrical products. Their compact body fits in tight spaces.
    Inverter Rated—When pairing with a variable frequency drive (AC motor speed control), choose a three-phase motor that’s inverter rated.
    Open Dripproof (ODP) Motor Enclosure—Open dripproof (ODP) enclosures have vents that let air flow over the motor, which keeps it cool and helps it run efficiently. Use them in clean, dry environments—the enclosure blocks drips and debris that fall from above, but dust and moisture can pass through the vents.
    Totally Enclosed Fan-Cooled (TEFC) Motor Enclosure—Totally enclosed fan-cooled (TEFC) enclosures don’t have vents, so they can be used in wet and dirty environments. They have an external fan that blows air over the outside of the enclosure to keep the motor cool. They’re not airtight, but since air isn’t flowing inside the enclosure, the motor won’t run as efficiently as it would in an open enclosure.
