Operation of Simple DC and AC Generators
Simple AC and DC generators have the exact same anatomy as a DC motor (with the exception of a slip ring or a split ring). The key difference is that in a generator, the armature is manually rotated and the output is electrical energy. Conversely, in a DC motor, the input was electrical energy, and this caused the armature to rotate.
What''s the difference between AC and DC?
DC is constant and moves in one direction. "A simple way to visualize the difference is that, when graphed, a DC current looks like a flat line, whereas the flow of AC on a graph makes a sinusoid or wave-like pattern," says Berggren. "This is because AC changes over time in an oscillating repetition — the up curve indicates the current ...
