Claim Text:
1. A hover engine comprising: an electric motor including a winding, a first set of permanent magnets, a shaft and a first structure which holds the first permanent magnets wherein the first structure is coupled to the shaft such that, when an electric current is applied to the winding, the shaft, the first structure and the first set of permanent magnets rotate about an axis of rotation; a second structure, coupled to one of the shaft or the first structure, the second structure holding a second set of permanent magnets wherein the second set of permanent magnets are rotated to induce eddy currents in a substrate such that the induced eddy currents and the second set of permanent magnets interact to generate a lift force; wherein the second set of permanent magnets is located between a first radial distance and a second radial distance that is greater than first radial distance, as measured along a line perpendicular to the axis of rotation; a housing, which at least partially encloses the electric motor and the second structure, the housing having a top, a bottom and sides, wherein a first portion of the bottom is disposed beneath the second set of permanent magnets and between the first radial distance and the second radial distance and a second portion of the bottom is disposed between the axis of rotation and the first radial distance, wherein the second portion extends upwards away from the substrate and to a height above a bottom of the second set of permanent magnets; and a third structure coupled to the second portion of the bottom, the third structure configured to receive a bearing wherein the shaft rests on the bearing to allow the shaft to rotate relative to the housing.
