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.

- Figure 10 illustrates a top-isometric view of the rotating ring of the torque-increasing device.

- Figure 12 illustrates a schematic view of the interaction between ring and rotor magnets, with the addition of diversion magnets, of the torque-increasing device.
- the torque-increasing device 1 is shown with commonly-associated accessory components. These include frame 100 with driver 110, affixed to shaft 114 via a coupling 112. The shaft 114 rotates on bearing blocks 116. Also shown is a load 122 connected to the shaft via pulleys 118 and belt 120.
- the torque-increasing device 1 is formed from a rotating assembly 130 placed between static plates 150, each of which supports a rotating ring 152.
- the rotating rings 152 are canted, or set an angle, with respect to the rotating assembly 130.
- FIG. 2 a top view of the magnetic assemblies of the torque-increasing device is shown.
- the torque-increasing device 1 is shown with rotating assembly 130 — formed primarily of rotor 132 — and rotating rings 152, the rotating rings 152 affixed to static plates 150.
- the rotor 132 spins in rotor rotation direction 240, and the rotating rings 152 spins in a matching direction, shown as ring rotation direction 242.
- the canted, or angled, relationship of the rotor 132 and rings 152 results in a minimum magnetic gap 170, a maximum magnetic gap 172, and a rotor angle with respect to static plate 174.
- the diversion magnets 180 and diversion magnet plate 182 are set in a plane parallel to the static plate 150 and rotating ring 152.
- the rotating ring 152 is shown supported by bearings 250, each of which rotates about a bearing shaft 252, the bearing shaft 252 supported by the static plate 150.
- diversion magnets 180 affixed to diversion magnet plate 182.
- the diversion magnets 180 are parallel to their respective rotating rings 152, and at an angle with respect to rotor 132.
- the directions of spinning are shown as rotor rotation direction 240 and ring rotation direction 242.
- the rotor 132 and rotating rings 152 are shown rotating, with the diversion magnets 180 set just outside the radius of the rotating rings. By diverting the flux lines between the magnets of the rotor 132 and the magnets of the rotating rings 152 during the lower segment of rotation, an unbalanced torque is captured.
- the drive pin slot 264 interacts with a drive pin 260 (see Figure 10) and drive pin block 262 (see Figure 10) to keep the rotor 132 and rotating rings 152 rotating together.
- a drive pin 260 see Figure 10
- drive pin block 262 see Figure 10
- the rotating assembly 130 is formed from a rotor 132 with a first face 134 that includes a first magnet set 136, and a second face 138 that includes a second magnet set 140.
- Each magnet set 136/140 includes rotor outer magnets 220, rotor inner magnets 222, and rotor center magnets 224.
- the rotating ring 152 includes ring outer magnets 226, ring inner magnets 228, and ring center magnets 230.
- the rotating ring 152 is supported by bearings 250, which transfer the weight of the rotating ring 152 to the static plate 150.
- FIG. 10 a top-isometric view of the rotating ring of the torque-increasing device is shown.
- the drive pin 260 mechanically connects the rotating ring 152 via a drive pin block 262, to the drive pin slot 264 in the shaft 114.
- the continuous flux line 232 passes directly from the magnets of the rotor 132 (left side) to the magnets of the ring 152 (right side).
- diversion magnets 180 and upper diversion magnets 184 are shown.
- the flux lines now follow a diverted path, shown as diverted flux line 234.
- the diversion of the flux lines reduces the magnetic interaction of the rotor 132 (left side) and the ring 152 (right side).
- diverted flux line 234 The diversion of the flux lines reduces the magnetic interaction of the rotor 132 (left side) and the ring 152 (right side).
- diverting the flux lines for less than an entire rotation of the rotor 132 and ring 152, an unbalanced/uneven torque is captured. This torque is applied to the shaft 114 (see Figure 5), and aids in its rotation.
