US-Made Face-Mount AC Motors



Wound, wired, and assembled in the U.S. These motors are manufactured for durability and include high-quality bearings, so they hold up to occasional overload conditions and spikes in torque. They bolt directly to gearboxes, pumps, and other machinery. These motors are more compact than base-mount motors and the direct, rigid connection to your equipment keeps them aligned. Rated for continuous duty, 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.
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. 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.

US-Made Base/Face-Mount AC Motors



Wound, wired, and assembled in the U.S. These motors are manufactured for durability and include high-quality bearings, so they hold up to occasional overload conditions and spikes in torque. Whether you’re switching between jobs or need flexibility during installation, these motors give you a variety of mounting options. Mount the feet to a flat surface or bolt the face directly to a gearbox, pump, or other machine. You can also do both at once for added stability in applications with high loads or vibration. They’re rated for continuous duty, so they’re often used with equipment that requires constant power, such as fans, pumps, and conveyors.

Face-Mount AC Brake Motors



A built-in brake engages to hold your equipment in place when these motors lose power, unlike standard AC motors. These motors are often used with conveyors to keep items in place after a power loss, and with hoists to prevent them from dropping a load. Also known as C-face motors, these bolt directly to your equipment. They’re rated for continuous duty, so they can run equipment that never turns off. Their shaft is keyed, and they come with a key stock. These motors have a TEFC (totally enclosed fan cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They’re not airtight, but they can be used in dirty, damp, and dusty environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

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.

Sanitary Washdown Face-Mount AC Motors



Bolt these motors directly to conveyors and other machines to power equipment on food and sanitary lines. They help you meet Good Manufacturing Practices (GMP) since they have many features that make them safe for sanitary and washdown environments. Smooth contours and a laser-marked nameplate limit the space where bacteria could grow. They don’t have feet, so they’re easy to rinse down thoroughly. A stainless steel enclosure, epoxy resin lined interior, and IP69 rating mean they withstand hot spraying water, harsh cleaners, and sanitizers common to food plants. A two-barrier seal keeps water from getting in through the shaft. If water does seep in, drain plugs let it out.
These motors are also called C-face motors. They’re rated for continuous duty, so they’ll run equipment that never turns off. Inverter rated, they also work with variable frequency drive (VFD) to run at different speeds. You can wire for clockwise or counterclockwise rotation; instructions are included. Their conduit box also rotates to connect conduit from any side without needing to reroute power.
TEFC (totally enclosed fan cooled) motors have a fan that cools the housing.

Sanitary Washdown Base/Face-Mount AC Motors



For versatility in food and sanitary lines, these motors mount by their feet or bolt directly to equipment to power pumps and other machines. Many features make them safe for sanitary and washdown environments: Smooth contours and a laser-marked nameplate limit where bacteria could grow. A stainless steel enclosure, epoxy resin lined interior, and IP69 rating mean they stand up to hot spraying water, chemicals, and harsh cleaners often used in food plants. A two-barrier seal on the shaft stops water from getting in. If water does seep in, drain plugs let it out.
Rated for continuous duty, these motors run equipment that never turns off. They’re also inverter rated, so they work with variable frequency drive (VFD) to run at different speeds. You can wire for clockwise or counterclockwise rotation; instructions are included. The conduit box also rotates, so there’s no need to reroute power when connecting conduit.

Programmable Base/Face-Mount Speed-Control Motors
These speed-control motors combine a variable-frequency drive and motor into one, saving space in your control panel and reducing the amount of wiring required. Bolt them directly to gearboxes, pumps, and other machinery, or use the welded base to mount them to a surface. You can 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. These motors are rated for continuous duty, so they'll run equipment that never turns off. All have automatic overload protection, which turns motors off if they become overheated and restarts them once they’ve cooled. A TEFC (totally enclosed fan cooled) motor enclosure protects these motors better than ODP (open dripproof) enclosures in damp and dusty environments. The external fan keeps the motor cool.
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.
Program these motors in a number of ways. You can download the free manufacturer software to your computer and connect to the motor via Bluetooth, or you can use a PC Connection Cord (sold separately) to connect your motor directly to your computer's USB port. The software allows you to control or monitor the motor in real time. To integrate them into larger control systems, these motors can be programmed using Modbus-RTU and BACnet protocols. Use a keypad (sold separately) to start or stop motors or to increase or decrease speed in real time. Its digital display also shows real-time motor information and allows you to edit control parameters. The keypad can be mounted up to 10 ft. away into a panel with the included cord to create a control station.

These motors also use Modbus-RTU and BACnet protocols, so you can integrate them into building and process control systems. You can also use a keypad (sold separately) to control these motors. It has a digital display that shows live motor information, such as output frequency and speed, and allows you to edit control parameters in real time. To create a control station, mount the keypad into a panel up to 10 ft. away from the motor with the included cord.
