Motor windings

I have been attempting to create motor windings for a small centrifual pump.I found these 2 pictures of windings created with Inventor but i was unable to view them as files.How are the copper wires formed to get the windings like in the pictures attached.
I could only manage the rim in the Inventor file and not the wires
It looks like a wire is created and then patterned but thi looks like a 3D sketch is needed for wire and then circle pattern????
Any help with this would be appreciated
