Now, let's apply some of the trig you have been learning to some of
the machinery you will be working with.
You will recognize this drawing as a representation of a simple,
basic generator. One conductor is shown rotating through the
magnetic field.
The next drawing shows the same generator, enlarged and positioned on the page so the
neutral plane is horizontal.
Let
the
neutral
plane
represent the X axis.
Label the neutral plane ...
at left, +X at right.
Let an imaginary line through
the strongest part of the
magnetic field (between the
exact centers of the pole
pieces) represent the Y axis.
Label the heavy center line
at top +Y. Label the heavy
center line at bottom -Y.
Now, with your pencil, extend
the heavy center lines from
top to bottom.
By adding the required lines and labels to the drawing, you have constructed coordinate
lines and quadrants in a generator. Check the accuracy of your work on the next page.
