Linear electric motor controller and system for providing linear control

A system for controlling an electric automotive component, comprising:

• an electric light;
• and
• an electric motor linear speed controller which comprises:
• a digital to analog converter means for converting an 8-bit bit digital signal to an analog voltage for setting voltage across a motor;
• a digital state machine means comprising a digital logic means and a state machine, which digital state machine is adapted and configured to convert the duty cycle of an input signal for output to the digital to analog converter means;
• and
• a closed loop feedback means for monitoring and setting the voltage across the motor.

A system for controlling the speed of an electric motor-comprising:

• a digital to analog converter means, for converting a digital signal to analog voltage for setting a voltage across the electric motor;
• a microprocessor and associated digital memory for generating the digital signal, the microprocessor configured to instantiate and operate a digital state machine for converting the duty cycle of an input signal to the microprocessor and associated digital memory, wherein the state machine sets the voltage supplied to the electric motor based on the input signal;
• and
• a closed loop feedback loop means adapted and configured to monitor the voltage across the motor and generate a signal for input to the microprocessor.

A linear speed controller for an automotive electric motor, comprising:

• a digital state machine for converting a duty cycle of an input signal for setting the voltage to be supplied to the motor;
• an over-current sense circuit, for monitoring the current across the electric motor;
• an over/under voltage sense circuit, for monitoring a supply voltage to the electric controller;
• a digital to analog converter, for converting an 8-bit digital signal to analog voltage for setting voltage across the electric motor;
• and
• a closed loop feedback loop and configured to monitor the voltage across the motor and generate a feedback signal for adjusting the voltage supplied to the motor.
