    • Number each component on the diagram and match it with description for clarity.
    • An illustrative table could summarize each part:

      Component Function Material(s) Diagram Label
      Armature Rotating part that generates torque Copper windings, iron core 1
      Brushes Conduct current to the commutator Carbon, Graphite 2
      Commutator Reverses current flow to maintain rotation Copper segments 3
      Field Magnet Creates a magnetic field to interact with armature Permanent magnets/Coils 4
  3. Wiring Configurations: Series vs. Parallel (and Variations)

    • Explain the different ways brushed motors can be wired. Focus on the two common configurations:
      • Series Wiring: Describe how the field coils are connected in series with the armature. Explain its characteristics (high starting torque, speed varies with load). Include a series wiring diagram.
      • Parallel (Shunt) Wiring: Describe how the field coils are connected in parallel with the armature. Explain its characteristics (more constant speed, lower starting torque). Include a parallel wiring diagram.
    • Use visual diagrams for each configuration, clearly showing the flow of current.
    • Discuss any variations or hybrid configurations that might exist.
    • Compare and contrast the configurations in a concise manner, possibly using a table:

      Feature Series Wiring Parallel (Shunt) Wiring
      Starting Torque High Low
      Speed Regulation Poor Good
      Load Sensitivity Highly sensitive Less Sensitive
      Common Application High torque situations Constant speed needs
