Abstract: The invention relates to a method and system for linear speed control for electric direct current motors, in which a digital to analog converter means is used for converting an 8-bit digital signal to an analog voltage for setting voltage across a motor, a digital state machine means is used for converting the duty cycle of an input signal for output to the digital to analog converter means, and a closed loop feedback means is used for monitoring and setting the voltage across the motor. An over-current sense circuit can be used for monitoring the current across or passing through the electric motor. An over/under voltage sense circuit can be used for monitoring voltage of the electric motor. The resulting 8-bit digital control signal is converted to an analog voltage for the electric motor.
