1. An electromagnetic propulsion system comprising:
a first plurality of stator coils wound about a first axis and configured to receive electric current to induce a first magnetic field;
a plurality of support structures that support the first plurality of stator coils;
a first coupler that surrounds a portion of the first plurality of stator coils and having a notch, the first coupler being oriented so that the notch can pass over one of the plurality of support structures when the first coupler moves along the first plurality of stator coils; and
a first plurality of sets of rotor coils attached to the first coupler and spaced around the first axis, the first plurality of sets of rotor coils being wound about axes that are parallel to the first axis and configured to receive electric current to induce magnetic fields that interact with the first magnetic field so that magnetic forces are applied to the first plurality of sets of rotor coils thereby propelling the first coupler along the first plurality of stator coils and providing a magnetic levitation force between the first plurality of sets of rotor coils and the first plurality of stator coils.
