So, I recently took apart 2 lawnmowers and a hoover. I am left with 3 armature arms. If you don't know what they are then look below,





So, they have coils of copper inside and I presume the other parts of metal are steel.

So what can I really do? Should I take them as they are? Dismantle them and how?

Also, the commutator has copper on it to. Small copper bars.

So I would appreciate some suggestions and opinions.
