Abstract

A method for operating a direct current (DC) motor is shown and described. The method includes generating a first pulse width modulated (PWM) signal having a first duty cycle, providing the first PWM signal as a PWM DC output for the DC motor, and adjusting the first duty cycle to control a speed of the DC motor. The method further includes sensing an electric current output to the motor using a current sensor and, when the sensed current exceeds a threshold, holding the PWM DC output off.
