| 20090289516 | Electrical generator arrangement - In some circumstances such as with regard to contra-rotating turbo prop arrangements in aircraft it is desirable to vary the pitch of the blades and/or provide de-icing facilities. Advantageously, these blade pitch and de-icing facilities could be provided through electrical actuators. Unfortunately, provision of electrical power to such rotating components traditionally requires utilisation of slip rings which are subject to wear. By providing a self-contained electrical generator comprising a first hub and second hub with respective generator parts it is possible to utilise the contra-rotating nature in order to create relative motion and therefore electrical power generation in coils opposed by permanent magnets. Slide contacts for electrical connection are avoided whilst electrical power can be generated within the rotating reference frame defined by the hubs. | 11-26-2009 |
| 20100225190 | Generator - A generator includes a body and at least one drive unit. The body includes at lease one winding portion and one magnetic pole portion. The winding portion is formed that is wrapped with windings, while the magnetic pole portion is rounded with a magnetic pole around the circumference of winding portion. Both the winding portion and the magnetic pole portion may run freely. The drive unit drives the winding portion and the magnetic pole portion, making the winding portion and the magnetic pole portion run reversely. Thus, the drive unit may drive the winding portion and the magnetic pole portion run oppositely for heightening the frequency of magnetic pole cutting to increase flux, and then increasing the efficiency of generator. | 09-09-2010 |
| 20110025157 | SYSTEM OF ELECTRICAL GENERATION FOR COUNTER-ROTATING OPEN-ROTOR BLADE DEVICE - A counter-rotating open-rotor blade aircraft propulsion system includes a structure supporting a plurality of blades. A rotor is drivingly coupled to the structure supporting the plurality of blades. The rotor includes a rotating coil disposed in the structure supporting the plurality of blades. A rotating magnetic field source includes two Halbach permanent magnet arrays. | 02-03-2011 |
| 20110285234 | GENERATOR WITH IMPROVED GENERATION EFFICIENCY AND ROTATIONAL FORCE - Disclosed is a generator that can produce electric power using water power, wave power or wind power. The generator characterized in that a plurality of magnet plates and separately-arranged coil plates are constructed in such a way that they can rotate in mutually opposing directions, and these magnet plates and coil plates are continuously and sequentially arranged on a rotating shaft, and a plurality of induction coils and electromotive coils installed on inner and outer cylinders proximate to the opposed ends of magnets arranged on the magnet plates are separately arranged on the coil plates. According to the generator, it is possible to obtain a further increased quantity of generation by means of the magnet plates and coil plates that rotate in mutually opposing directions even in the case that water power or wind power used in generation is weak. In addition, even if the energy supply source such as wind power, wave power or water power acts continuously or intermittently, the rotational force between the magnet plates and coil plates is increased greatly by the electromotive coils that confer repulsive force on the magnets to make it possible to produce much higher generation energy, so it is very economical. | 11-24-2011 |
| 20120286610 | Increased efficiency dual rotational electric motor/generator - An enhanced dual rotational electric motor/generator includes an armature that rotates about a central axis in one direction, a stator that rotates about the central axis in an opposite direction, an axle that extends along the central axis and is secured to the armature, an axle support, a rotational output alignment mechanism for converting the opposite rotations of the armature and stator into a common rotational output direction, and an electrical connection mechanism that supplies functioning electrical communication between the motor/generator and external electrical circuitry while operating the motor/generator. | 11-15-2012 |
| 20130257208 | PERMANENT MAGNET ELECTRICAL GENERATOR AND METHOD OF PRODUCING ELECTRICAL ENERGY - Permanent magnet electric generators and methods of generating electrical energy are provided. The generators include two rack assemblies each including concentric circular cylindrical cores having circular arrangements of permanent magnets and electrical conductors. The two rack assemblies are axially engaged wherein magnets of the concentric circular cylindrical cores repel adjacent magnets and thereby rotate the cylindrical cores. The rotation of the adjacent magnets in the cores induces an electric current within the electrical conductors, which can be extracted and used in a broad range of applications. Various mechanisms adapted to engage and disengage the two rack assemblies are provided, including the introduction of a vacuum into the generator housing. Methods of generating electrical energy and electrical cores having permanent magnets and conductors are also disclosed. | 10-03-2013 |
