Base-Mount AC Motors
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.
When pairing with a variable frequency drive (AC motor speed control), choose a three-phase motor that’s inverter rated.
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.
Totally enclosed fan cooled (TEFC) enclosures don’t have vents, so they can be used in damp 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.

Face-Mount AC Motors
Bolt these motors directly to gearboxes, pumps, and other machinery. They’re more compact than base-mount motors and the direct, rigid connection to your equipment helps keep them aligned. Rated for continuous duty, they are often used with equipment that requires constant power, such as fans and conveyors. These motors are inverter-rated, so you can use them with a variable frequency drive (AC motor speed control).
A totally enclosed fan cooled (TEFC) enclosure means you can use them in damp and dirty environments since they don’t have vents. 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.
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.

Base/Face-Mount AC Motors
Whether you’re switching between jobs or need flexibility during installation, these motors give you a variety of mounting options. Fix the feet to a flat surface or bolt the face directly to a gearbox, pump, or other machinery. You can also do both at once for added stability in applications with high loads or vibration. These motors are rated for continuous duty, so they’re often used for equipment that requires constant power, such as fans, pumps, and conveyors. They’re also inverter-rated, so you can use them with a variable frequency drive (AC motor speed control).
A totally enclosed fan cooled (TEFC) enclosure means you can install them in damp and dirty environments since they don’t have vents. An external fan blows air over the outside of the enclosure to keep these motors 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.
These motors 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.
