pole shoes in opposite directions to generate opposing
magnetic fields.
The field coils connect in series with the armature
winding through the starter brushes. This design pennits
all current pas sing through the field coil circuit to also
pass through the armature windings.
The armature is the only rotating component of the
starter. It is located between the drive and commutator
end frames and the field windings. When the starter operates, the current passing through the armature produces a magnetic field in each of its conductors. The
reaction between the armature’s magnetic field and the
magnetic fields produced by the field coils causes the ar-
mature to rotate. This mechanical energy is then used to
crank the engine.
