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.

When pairing with a variable frequency drive (AC motor speed control), choose a three-phase motor that’s inverter rated.

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. Open drip proof (ODP) and open slotted band (OPSB) enclosures only have vents.Enclosures that are totally enclosed don’t have vents, so they can be used in damp 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. Totally enclosed fan cooled (TEFC) enclosures have an external fan that blows air over the outside of the enclosure to keep the motor cool. Motors with overload protection turn off in overload conditions to prevent motor damage. Automatic overload protection starts the motor automatically after it cools.

Optional 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.

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.
