    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.
    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 only have vents.
    Open Slotted Band (OPSB) Motor Enclosure—Open slotted band (OPSB) 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.
    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.

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

    These motors are rated for environments where hazardous material is present. They are continuous duty and mount horizontally. You can wire for clockwise or counterclockwise rotation; instructions are included. The base is welded to the enclosure.
    Hazardous Location Rating—Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment.

    Unlike standard AC motors, these motors have an integrated brake that activates after a power loss to hold your equipment in place. They’re often used with conveyors to stop them from moving backwards after a power loss, and with hoists to prevent them from dropping a load. Mount their base to flat surfaces. Rated for continuous duty, these motors can run equipment that never turns off. Their shaft is keyed, and they come with key stock.
    Totally Enclosed Fan-Cooled (TEFC) Motor Enclosure—These motors have a TEFC (totally enclosed fan-cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They aren’t airtight, but they can be used in dirty, dusty, and wet environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

    Save space in your control panel with a variable-frequency drive and motor in one unit. These motors require less wiring than motors that need to be attached to a separate drive. They have a base mount that’s welded to the enclosure, so you can secure them to a flat surface. Program the drive to start, stop, change speed, and reverse direction based on inputs from a PLC or sensor. These motors are often used to start or stop a conveyor based on PLC commands or vary the speed of a fan to maintain a room’s temperature.
    The shaft is keyed and comes with key stock. Rated for continuous duty, these motors can run machines that require constant power. All have automatic overload protection, which turns motors off if they become overheated and restarts them once they’ve cooled.
    An IE5 efficiency rating means these motors and drives are rated for the highest efficiency available. From partial to full output, they'll use less electricity than motors with other ratings.
    Download free software to control and monitor them in real time. Connect them to your computer via Bluetooth or use a PC connection cord to plug them into a USB port. To integrate them into larger control systems, these motors can be programmed using Modbus-RTU and BACnet protocols.
    Totally Enclosed Fan-Cooled (TEFC) Motor Enclosure—These motors also have totally enclosed fan-cooled (TEFC) enclosures, which don’t have vents, so you can install them in damp and dirty environments. An external fan blows air over the outside of the enclosure to keep these motors cool.
