| 20080203841 | HIGH-TORQUE MOTOR - A motor that delivers high force linear motion or high torque rotary motion to a moving element. The motor may include a driving brake, a driver, a holding brake and a flexible moving element. Operation of the motor may involve activating the holding brake, activating the driver to flex the moving element, activating the holding brake to maintain the position of a portion of the moving element, releasing the driving brake, and restoring the moving element to an unflexed position. The elements are arranged to provide linear motion, belt-driven rotary motion, or directly-coupled rotary motion using brakes and drivers arranged in linear or circular fashion. Drivers may be linear or rotary actuators or motors based on electrostatic, piezoelectric, magnetic, or electrostrictive properties. The brakes may be applied through electrostatic forces, magnetic forces, or mechanical gears engaged with a linear or rotary driving mechanism. | 08-28-2008 |

| 20110298324 | ELECTROMAGNETIC NON-CONTACT BRAKE - An electromagnetic non-contact brake may include an annular stator assembly including a predetermined number of poles formed about the stator assembly. A rotor assembly is disposed within the stator assembly and may include a selected number of poles formed about the rotor assembly. A shaft may extend through a center portion of the rotor assembly and be fixedly attached to the rotor assembly. An electrical connection is adapted to controllably apply electrical power to at least one of the stator assembly and the rotor assembly. The electrical power causes a plurality of magnetic fields to be simultaneously generated around at least one of the stator assembly and the rotor assembly by the poles. Each of the plurality of magnetic fields causes the poles of the stator assembly and the poles of the rotor assembly to be magnetically attracted to one another to substantially prevent the rotor assembly and the shaft from rotating. | 12-08-2011 |
| 20120019087 | Magnetic Electron Exciter and Methods - A magnetic electron exciter includes a rotor adapted to be rotated within a selected range of rotational speeds, and having a plurality of magnets mounted therein selected distances from the rotational axis of the rotor. A plurality of coils are positioned adjacent to the rotor, whereby rotation of the rotor creates an electrical current in the coils. First and second electrodes are spaced apart a determined distance, and are electrically connected with the coils to create an arc between the electrodes when the rotor is rotated relative to the coils. The magnetic electron exciter can be used as a non-contact brake for machines, such as motor vehicles, wind turbines and the like. | 01-26-2012 |

| 20150069870 | FLYWHEEL MAGNETIC CONTROLLER - A flywheel magnetic controller for mating with an existing flywheel has a magnetic wheel, an external driving module, an elongated pulling element and a rotary engaged adjustment unit. The cable assembly adjustment structure of the flywheel magnetic controller is simplified structurally, thus greatly reducing the fabrication and assembly cost, and facilitating flexible and universal assembly with better applicability. | 03-12-2015 |
| 20160006334 | SEALESS, LIQUID COOLED EDDY CURRENT ENERGY ABSORPTION SYSTEM - The disclosed apparatus relates to a non-frictional, rotational, continuous energy absorbing device utilizing internal liquid cooling and having no dynamic seals. The apparatus is comprised of a rotor assembly containing magnets, cooling chambers containing magnetically driven impellers, actuators to adjust the axial positioning of said chambers, and other variations of the apparatus including an air-cooled design and additional friction braking. Braking torque is generated through shearing of eddy currents as the cooling chambers are moved axially closer to the rotor by actuators. The same action also drives magnetically driven impellers, resulting in coolant flow. Braking energy absorption increases as does coolant flow as the distance between the cooling chambers and the rotor is decreased. As the distanced between the rotor and cooling chambers increase, both energy absorption and coolant flow decrease to zero. The coolant flows from the cooling chambers to a heat exchanger to dissipate the energy. | 01-07-2016 |
