Is there such a thing? I'm thinking the stator design would be like the coreless pancake motors I've seen on here. And the "cage" rotor would be sort of a "spoked" shape. An inner ring, an outer ring, with the copper conductor "spokes" connecting them. Would that be the right orientation to work? Asynchronous is a goal.
Also do induction motors need laminations on both stator and rotor? I see coreless designs on here, so what do lamenations really do?
