The stator from an induction motor is a stack of thin laminations. If you are making a motor, you can use as many or as few of those laminations as you want.
One of the problems with a pancake motor (large diameter relative to length) is that it has large losses due to the end turns plus 3D magnetic field effects. They are not efficient.
Large neodymium magnets are a real challenge to handle.
