    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.
    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.
    Automatic—Motors with automatic overload protection turn off in overload conditions to prevent damage. Once they cool down, they start again automatically.

    Wound, wired, and assembled in the U.S. These base-mount motors are manufactured for durability and include high-quality bearings, so they hold up to occasional overload conditions and spikes in torque. Rated for continuous duty, they’re often used with equipment that requires constant power, such as fans, pumps, and conveyors. Bolt the base of these motors to any flat surface and connect the shaft to your load.
    Enclosures that are open 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.
    Enclosures that are totally enclosed don’t have vents, so they can be used in wet and dirty environments. 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.
    Open Dripproof (ODP) Motor Enclosure—Open dripproof (ODP) enclosures only have vents.
    Totally Enclosed Fan-Cooled (TEFC) Motor Enclosure—Totally enclosed fan-cooled (TEFC) enclosures have an external fan that blows air over the outside of the enclosure to keep the motor cool.
    Vibration-Damping Base—Motors with a vibration-damping base have rubber rings between the base and enclosure to minimize vibration.
    Automatic—Automatic overload protection starts the motor automatically after it cools.
    Manual—Manual overload protection must be reset manually to start the motor after it cools.
    Overload Protection Type—Motors with overload protection turn off in overload conditions to prevent motor damage.
    Drip Covers—Drip covers are recommended when your motor will be mounted with the shaft facing down. They attach to the back side of the motor to prevent moisture from pooling on top.
