A motor controller system ( ) for dc power source motors ( ) which includes a sensor device ( ) that operates to measure and generate a voltage signal from the motor current and the rate of change of said current, and a programmable input/output processor ( ) which receives voltage signals as input from the motor current, dc power source ( ) and/or motor ( ) and compares on or more of these voltage signals to one or more control parameters. Based upon these comparisons, the processor ( ) generates a pulse width modulation control signal, which triggers a switching mechanism ( ) and related interrupt service routing to make adjustments to the operational parameters of the motor by periodic interruption of the motor current.
