"If you only knew the magnificence of the 3, 6 and 9, then you would have a key to the universe.”

Because we all know that the effects that are manifested when a closed
circuit approaches and moves away from a magnetic center are the same as
when, this circuit being still and motionless, the MAGNETIC field is increased
and reduced in intensity; since any Variation , occurring in the flow traversing
a circuit is producing electrical induced current

By varying the relative position upon the commutator of the respective brushes automatically in proportion to the varying electrical conditions of the working-circuit the current developed can be regulated in proportion to the demands in the working-circuit.

It was considered the
possibility of building a machine that would work, not in the principle of
movement, as do the current dynamos, but using the principle of increase
and decrease, this is the variation of the power of the magnetic field, or the
electrical current which produces it.

If, for instance, the commutator-space between the brushes a and c, when the latter is at the neutral point, is diminished, a current will flow from the point Y over the shunt C to the brush b, thus strengthening the current in the part M', and partly neutralizing the current in the part M; but if the space between the brushes a and c is increased, the current will flow over the auxiliary brush in an opposite direction, and the current in M will be strengthened, and in M' partly neutralized.

Therefore it
matters little to these induced currents if they were obtained by the turning of
the induced, or by the variation of the magnetic flux that runs through them;

It will be apparent that the respective cores of the field-magnets are subject to the neutralizing or intensifying effects of the current in the shunt through c', and the magnetism of the cores will be partially neutralized or the point of greatest magnetism shifted, so that it will be more or less remote from or approaching to the armature, and hence the aggregate energizing actions of the field magnets on the armature will be correspondingly Varied.

Here what it is constantly changing is the intensity of the excitatory current
which drives the electromagnets and this is accomplished using a resistance,
through which circulates a proper current, which is taken from one foreign
origin into one or more electromagnets, magnetize one or more
electromagnets and, while the current is higher or lower the magnetization of
the electromagnets is decreasing or increasing and varying, therefore, the
intensity of the magnetic field , this is, the flow which crosses the induced
circuit.

The relative positions of the respective brushes are varied, either automatically or by hand, so that the shunt becomes inoperative when the auxiliary-brush has a certain position upon the commutator, but when said auxiliary brush is moved in its relation to the main brushes, or the latter are moved in their relation to the auxiliary brush, the electric condition is disturbed and more or less of the current through the field-helices is diverted through the shunt or a current passed over said shunt to the field-helices.
