Abstract
A method for operating a direct current (DC) motor is shown and described. The method includes using pulse width modulated (PWM) DC output to control the speed of the DC motor. The method further includes sensing current output to the motor. When the sensed current exceeds a threshold, the method holds the PWM DC output off.
