US-Made Base-Mount AC Motors




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. Manual overload protection must be reset manually to start the motor 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.

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.
Open drip proof (ODP) enclosures 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.
Motors with automatic overload protection turn off in overload conditions to prevent damage. Once they cool down, they start again automatically.

Base-Mount AC Brake Motors



Unlike standard AC motors, these motors have an integrated brake that activates after a power loss to hold your equipment in place. They’re often used with conveyors to stop them from moving backwards after a power loss, and with hoists to prevent them from dropping a load. Mount their base to flat surfaces. Rated for continuous duty, these motors can run equipment that never turns off. Their shaft is keyed, and they come with key stock. These motors have a TEFC (totally enclosed fan cooled) enclosure that protects better than an ODP (open dripproof) enclosure. They aren’t airtight, but they can be used in dirty, dusty, and damp environments. To keep the motor cool, the enclosure has an external fan that blows air over the outside of the motor.

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.

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.

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.
