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.

Motors with a vibration-damping base have rubber rings between the base and enclosure to minimize vibration.

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 air-over (TEAO) enclosures don’t have their own fan. They need to be mounted in the airflow of an external fan or blower to keep the motor cool, so they’re often found in HVAC systems. Motors with overload protection turn off in overload conditions to prevent motor damage. Automatic overload protection starts the motor automatically after it cools.
