This probably a "bad dxf import" example. The when the dxf file was created, it wasn't created with enough precision to make a good finite element model--points that should coincide don't, etc. I've attached a redrawn version of your motor. The geometry is consistent, but I'm not sure that the currents are defined how you intended them to be.
