FIGURE 2. MULTIPLE-LOOP GENERATOR.
This figure shows two loops of wire in the magnetic field. Also, two more segments have been
added to the commutator. When these loops are turned, we will get four pulsations of current
instead of two.
In the generator with one loop, the generator output started with zero, then built up to maximum,
and dropped back to zero for each half turn of the loop. When two loops are used, one loop is in
the up-and-down position and producing no current; the other loop is producing maximum current.
So, in addition to getting four pulsations of current per revolution, the voltage does not drop to
zero.
