1. An electric motor linear speed controller, comprising:

  • a digital to analog converter means for converting an 8-bit digital signal to an analog voltage for setting voltage across a motor;

    a digital state machine means comprising digital logic means and a state machine for converting the duty cycle of an input signal for output to the digital to analog converter means, wherein the digital logic means converts the input signal to a digital signal that identifies the duty cycle for input to the state machine; and

    a closed loop feedback means for monitoring and setting the voltage across the motor.
