A motor controller system (15a) for dc power source motors (10) which includes a sensor device (16) 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 (12) which receives voltage signals as input from the motor current, dc power source (11) and/or motor (10) and compares on or more of these voltage signals to one or more control parameters. Based upon these comparisons, the processor (12) generates a pulse width modulation control signal, which tr...
1. A motor controller system for dc-powered motors comprised of a dc power source, a motor and corresponding circuit, said motor control system being effective to maximize motor efficiency and extend the life of said dc power source, and comprising: a. a current sensor device which measures the current of said motor and the rate of change of said current and generates a corresponding voltage signal; b. a programmable input/output processor which receives as input said current sensor voltage signal and a voltage signal from the dc power source for sa...
