Final answer:
In the starter housing, field coils are wrapped around the armature shoes to create strong magnetic fields. These magnetic fields are essential for the operation of the starter motor, as they interact with the permanent magnets or other magnetic components to generate the necessary torque.
Step-by-step explanation:
In the starter housing, field coils are wrapped around the armature shoes to create strong magnetic fields. These magnetic fields are essential for the operation of the starter motor, as they interact with the permanent magnets or other magnetic components to generate the necessary torque.
The field coils are typically made of copper wire, which is wound in multiple turns to increase the strength of the magnetic field. The current passing through the field coils creates an electromagnetic field that induces a magnetic force on the armature shoes, causing them to move and generate mechanical motion.
Overall, the field coils play a crucial role in converting electrical energy into mechanical energy in the starter motor, allowing for the starting of internal combustion engines.
