What is another name for the pole pieces?
Pole shoes
15
All of the following are used to increase starter motor power and smoothness, except:
connecting each winding to its own segment on the commutator
removing the pole shoes.
a commutator with many segments.
several loops of wire.
15
A(n) _____ is a stationary insulated wire wrapped in a circular shape around iron pole shoes located inside the starter motor housing.
commutator
armature
field winding
pinion
15
The magnetic field developed between the pole shoes can be _____ times larger than that of a permanent magnet.

15
The starter pinion gear is the small gear on the _____ that engages the large gear on the _____.
armature shaft, engine flywheel.
15
Why is an overrunning clutch needed?
Without the overrunning clutch, the starter could be driven by the engine flywheel. The flywheel gear could spin the starter too fast and cause armature damage.
15

on a body panel away from the starter
on the starter motor or on a body panel away from the starte
15
A(n) _____ is sometimes used to further increase the rotating force applied to the engine flywheel.
reduction starter
15
A _____ uses a small current flow from the start switch or ECM to control a slightly higher current flow to the starter solenoid.
diode
neutral safety switch
transistor
starter relay
