Really the one other pieces that would be negative would be the rotor and stator.

No. A individual or responsible occasion need to consent for the surgical procedure. A physician may cease managing you when you refuse his wellness treatment directions.
ROTOR: The rotor assembly includes numerous "pole sneakers", copper area windings, and the slip rings, all mounted within the central shaft in the alternator.
