What are these ?? in a motor?

I've taken a squirle cage ventilation motor appart to see what the laminations of the core material is within the electric coil. The core material then capsules an armature with an angled/off-set, made of aluminum vanes. How does the off-set aid in the armature rotating? What I also noticed is that there are two closed-loop, bare copper wires encircling the metal laminations, as if it were holding the whole essemble together. What is the electrical dynamic involvement with theses copper wires or is it simply for essembling porposes?

Thanks

It sounds like you are describing a shaded pole motor. The copper loops provide a phase shift for torque purposes.
