Face-Mount Speed-Control Motors

Set and maintain the speed of these motors with the included speed control, which automatically adjusts the power based on feedback from a built-in sensor. These motors combine the speed control characteristics of permanent-magnet brushless DC motors with the convenience of AC power—an integrated inverter means they operate on 120 volts AC. They bolt directly to gearboxes, pumps, and other machinery.
These motors have manual overload protection, which turns them off if they overheat. An LED on the control face indicates when the overload protection is triggered—flip the reset switch to start motors once they cool. The panel-mount controller also lets you turn motors on or off, change the speed, and switch between clockwise or counterclockwise rotation. To create a control station, mount it up to 10 feet from the motor with the included cable.
Rated for continuous duty, these motors can run machines that require constant power, such as fans and conveyors. They have totally enclosed non-ventilated (TENV) enclosures, which don’t have vents, so you can install them in damp and dirty environments. They don’t have a fan, so motors get warmer and run less efficiently than they would in open or fan-cooled enclosures.

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.

Programmable Base-Mount Speed-Control Motors
Save space in your control panel with a variable-frequency drive and motor in one unit. These motors require less wiring than motors that need to be attached to a separate drive. They have a base mount that’s welded to the enclosure, so you can secure them to a flat surface. 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. Rated for continuous duty, these motors can run machines that require constant power. All have automatic overload protection, which turns motors off if they become overheated and restarts them once they’ve cooled. They also have totally enclosed fan cooled (TEFC) enclosures, which don’t have vents, so you can install them in damp and dirty environments. An external fan blows air over the outside of the enclosure to keep these motors cool.
