Definitions

• This invention relates to the field of mechanical devices producing rotational energy and more particularly to a device that captures additional torque in a rotating system.
• Rotational mechanical energy is the workhorse of our world. From pumping liquids to moving trains, rotational motion is critical.
• horsepower is the metric most often cited when discussing the capability of a machine, it is torque that allows machines to accomplish their work. Without the torque to rotate, there is no work.
• the torque-increasing device includes multiple rotating discs, rings, or rotors, each including embedded or affixed magnets.
• the discs are canted toward each other, thus passing closer to each during the first half of a rotation, and further apart during the second half of a rotation.
• the attractive force is split into two vectors: a vector that is perpendicular to an imaginary plane that divides the discs, and a torque vector that is parallel to the face of the rotors.
• the torque captured by the magnetic attraction is always toward the section of the discs where the magnets are closest — the magnets prefer to be closer together rather than further apart.
• the upper 180-degree segment of magnets wants to rotate in a first direction to be closer together, and the lower 180-degree segment of magnets wants to rotate in a second direction to be closer together.
• the first and second directions are opposites, thus the torques cancel out.
• the solution is to disrupt the attraction of the magnets on either the upper or lower half of the rotor, or a segment of the upper or lower half, thus unbalancing the magnetic forces and causing rotation.
• magnets can be located at a diameter greater than the outermost magnets of the rotors, or within a diameter of the innermost magnets.
• the flux line diversion magnets are preferably located in the gap between the rotating discs.
• This interference is visualized as a modification to the flux lines, or the field lines created by the magnetic field.
• the force vector is modified. This magnetic modification is applied to only a section of the discs, resulting in an imbalance.
• the goal is to alter the path of flux lines, thus preventing capture of the torque during a segment of the rotation.
• the result is an imbalanced torque.
• the magnetic discs, rotors, or rings rotate together on a common shaft. By mechanically coupling the rotation together, the magnetic interaction across the rotor and rings is maintained, and the torque vector, which is parallel to the rotor faces, is transferred to the shaft.
• permanent magnets are preferred, but electromagnets are a possible substitution.
• Discrete permanent magnets are shown, but arc-shaped magnets can be substituted to result in a smoother action, rather than the “cogging” or stepped rotation effect that discrete magnets can cause.
• the magnets are preferably placed in a Halbach arrangement, thus focusing the magnetic flux away from the rotor and plate faces.
• a typical Halbach arrangement of magnets is:
• Magnetic flux is a measurement of the magnetic field that passes through a given area. The measurement and illustration of magnetic flux is used to understand and measure the magnetic field present across a given area. Flux lines are a visualization of the magnetic field.
