Abstract

See full text

An electromagnetic propulsion system includes a plurality of primary windings and a permanent magnet arranged to move with respect to the plurality of primary windings. A secondary winding of the system is disposed in a non-moving relationship with the permanent magnet. An excitation energy is applied to the plurality of primary windings for creating a magnetic field that includes a base component and low frequency harmonic components. The base component substantially contributes toward motion between the plurality of primary windings and the permanent magnet and the low frequency harmonic components substantially contributes toward generating an electro-motive force in the secondary winding based on displacement between the plurality of primary windings and the permanent magnet.
