ABSTRACT:
A universal signal translator for use in a speed control system for connecting a speed controller producing speed command output signals having a first range of voltages or currents, to a motor speed regulator designed to operate on a second, different range of input control voltages from a control potentiometer. The signal translator can be connected between the speed controller and the motor speed regulator and will automatically couple control signals from the controller to the speed regulator while automatically accommodating a wide variety of control voltage ranges, without requiring any modifications or adjustments. The translator provides output signals to the regulator proportional to the speed command signals from the controller and automatically scaled to the appropriate voltage range of the regulator. This permits a standard universal signal translator to be used with a wide variety of different makes and models of speed regulators, without requiring expensive engineering modifications or redesign.
