I am actually trying to explain how a Linear Induction Motor in new meg-lev style trains operates. It is basically as if the stator and rotor of a standard electric motor are sliced on one end and then rolled flat. I am not sure how to do this and have the coils of the stator remain intact as it unrolls itself. The problem may be easier to think of in reverse, i.e. how would one animate a flat sheet rolling into a cylinder? Do you have any ideas? Thanks, Darin
