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. They 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.

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 (sold separately) 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. 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.
