About Electric Motors
When replacing a motor, use the information on your motor’s nameplate to guide your selection.

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 an IEC frame size meet international standards for electrical products. Their compact body fits in tight spaces.
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.
Motors that cannot be sold to the regions listed are restricted due to energy efficiency regulations.

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).
