Abstract
Abstract The magnetic turbine of the present invention has an armature mounted to rotate about an axis of rotation. Each of a plurality of permanent magnets carried by the armature are magnetically oriented with each adjacent magnet having opposite magnetic polarities. Each of a plurality of drive rotor permanent magnets is rotatably mounted at a fixed radial position with respect to the armature axis of rotation and is disposed in magnetic proximity with respect to the permanent magnets carried by the armature. A means is provided for driving all of the drive rotor permanent magnets at a common speed and in a common direction. Each of the drive rotor permanent magnets is magnetically oriented for rotating the armature at a speed that is proportional to the rotating speed of the drive rotor permanent magnets. The rotation of the drive rotor magnets pulls the armature magnets in a direction opposite thereto after an initial magnetically locked condition is overcome by an input drive means.
