Title: Electromagnetic propulsion system

Abstract

An electromagnetic propulsion system comprises a plurality of stator coils wound about a first axis, a plurality of support structures, a coupler that surrounds a portion of the stator coils, and a plurality of rotor coils wound about an axis that is parallel to the first axis. The stator coils are configured to receive electric current to induce a first magnetic field. The support structures support the stator coils. The coupler includes a notch oriented so that one of the support structures can pass through the notch when the coupler moves along the stator coils. The rotor coils are attached to the coupler and are configured to receive electric current to induce a magnetic field that interacts with the first magnetic field so that a magnetic force is applied to the rotor coils, thereby propelling the coupler and the rotor coils along the stator coils.
