Abstract: The Superconducting Electrodynamic Turbine produces thrust by transferring momentum to the Earth, via the geomagnetic field. A pair of counter-rotating electrodynamic rotors, that are made from a Superconductor, act together to displace the surrounding geomagnetic field. The rotation of a Superconductor in the geomagnetic field, referred to as the exciting field, creates persistent eddy currents in the Superconductor. Lenz's Law states that an induced eddy current produces a magnetic field that opposes the relative change in the exciting field. A continuous increment of energy, or work, has to be expended to overcome the opposing force and to keep the counter-rotating electrodynamic rotors rotating at a constant rate. This work is transferred to the magnetic field. The Electrodynamic Turbine produces a unidirectional displacement in the exciting magnetic field, creating a force or thrust.

The stator and the field rotor are arranged in series in an axial direction of the motor. This structure increases an amount of a winding coil of the stator and magnets in the field rotor, and an output torque of the motor.

This structure provides a reduced axial size of the motor with high performance.
