Below is a list of Reversible Motor manufacturers from Portland, Oregon. A reversible motor is an electric motor that can run on either alternating current (AC) or direct current (DC) and is able to reverse the direction of the motor’s rotation. Typically done through the use of a switch, the reverse and direction in reversible motors is much easier than other motors such as induction motors, which would require halting the motor altogether, changing the wire connections and making a reverse run.
