    Programmable Face-Mount Speed-Control Motors

    Image of Attribute. Front orientation. Contains Annotated. Programmable Face-Mount Speed-Control Motors.
    Image of Attribute. Side1 orientation. Contains Annotated. Programmable Face-Mount Speed-Control Motors.
    A variable-frequency drive and motor in one unit, these motors save space in your control panel and require less wiring than separate drives and motors. They bolt directly to gearboxes, pumps, and other machinery. 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.
    Rated for continuous duty, these motors can run machines that require constant power.
    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.
    Download free software to control and monitor them in real time. Connect them to your computer via Bluetooth or use a PC connection cord to plug them into a USB port. These motors also use Modbus-RTU and BACnet protocols, so you can integrate them into building and process control systems.
    Totally Enclosed Fan-Cooled (TEFC) Motor Enclosure—These motors 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. All have automatic overload protection, which turns motors off if they become overheated and restarts them once they’ve cooled.
