Description of electric motors

Why [Arc<Material>]?

• Reuse of the same material (e.g. copper) over multiple wires, even when deserializing -> serde_mosaic

Why Box?

• Generics: Generics bloat: Motor<StatorWinding, StatorCore, RotorWinding, RotorCore, RotorMagnet> … -> Every function which takes a motor would need to be completely generic
• Enum: a) Not user-extensible. b) Adding a new wire type would be a breaking change

Performance issue compensated by caching in SimMotor -> No need to call methods of wires, slots etc. in a tight loop of a simulation.“ “
