Electromagnetic Compatibility of Direct Current Motors in an Automobile Environment 2005-01-0637

As the volume and complexity of electronics increases in automobiles, so does the complexity of the electromagnetic relationship between systems. The reliability and functionality of electronic systems in automobiles can be affected by noise sources such as direct current (DC) motors.
