The study of DC machines using animation, is based on multimedia technology Flash, which gives us a range of possibilities for animation of circuits. Here are described and represented continuous current generators with their characteristics and DC motors with its characteristic features. About continuous current generators we will refer to parallel excitation generators, serial and mixed, and of their characteristics will be analyzed: external feature and the blank. And with reference to the current engine will analyze operating modes of the series excitation motors, parallel and mixed, and their characteristics: mechanical characteristics and the speed characteristics
