Motor Drives & Motor Controllers
Control Resources designs and manufactures both off-the-shelf and custom fractional HP motor drives and motor controllers for the OEM (Original Equipment Manufacturers) market. Our controllers and drives regulate a variety of motor types based on temperature, pressure, analog control signal, remote transducer, potentiometer or MODBUS signal. Many models are customer programmable using the proprietary Navigator handheld remote programmer. Typical applications include: fans, pumps, compressors, conveyors, lifts, doors… and more.
