20100066187 | INTRODUCED IN ELECTRIC MOTOR - “IMPROVEMENT INTRODUCED IN ELECTRIC MOTOR”, foreseeing an electric motor indicated by reference (M) essentially comprising a stator ( | 03-18-2010 |
20100133937 | METHOD AND DEVICE FOR ENERGY GENERATION - A method and device for using radial relative displacement between a magnet and coil to generate electricity from fluid motion. The device includes a support structural component, a movable magnetic structure, a rotating structural component, and bearings. The movable magnetic structure is coupled to the support structural component. The rotating structural component rotates relative to the support structural component. The bearings are coupled to or disposed with the rotating structural component. The rotation of the rotating structural component results in forces applied by the bearings on the movable magnetic structure and movement of the movable magnetic structure. | 06-03-2010 |
20100213778 | Magnetic Motor With Associated Alternator - An electromechanical device or magnetic motor includes a plurality of rotor magnet assemblies, a plurality of drive magnet assemblies that are laterally moveable with respect to the rotor magnet assemblies, a timing assembly for generating power pulses selectively supplied to the drive magnet assemblies, and electromagnetic coils associated with the drive magnet assemblies to receive the power pulses from the timing assembly to momentarily disrupt the magnetic field of such assemblies at selected times. The magnetic assemblies of the rotor mechanically rotate a shaft and interact with alternator windings to generate electrical power. The magnetic motor is self-contained with start/stop, rotational speed, diagnostics, global positioning, CPU and interface capability. | 08-26-2010 |
20110181141 | Electric Motor and Position Holding Device for Such an Electric Motor - An electric motor, particularly for an actuating device for displacing a control device, such as a valve, a gate valve, a blow-out preventer or the like, for use in oil or gas production includes a stator and a rotor assigned to a motor shaft, and a position holding device for exerting a holding torque on the motor shaft. To improve an electric motor of this type such that said motor is of a compact structure, includes less additional parts for a corresponding position holding device and, particularly in case of failure of an external power supply, reliably prevents a situation where the motor shaft is moved out of the attained position upon corresponding pressure application e.g. by the control device, the position holding device comprises a plurality of permanent magnets, the permanent magnets being arranged in radial direction relative to the rotor and the motor shaft, respectively. | 07-28-2011 |
20120025652 | GENERATOR - The generator comprises a stator ( | 02-02-2012 |
20130229081 | POWER MAGNETIC PLANETARY GEAR SET - A power magnetic planetary gear set uses stator of a motor to provide electrically generated magnetic sections. The electrically generated magnetic sections are variable under the excitation control of coils and driver so that either the outer stator or the sun stator of the magnetic planetary gear set may be stationary and still provide self-revolutionary magnetic forces toward the planet gears disposed therebetween. The planet gears are also mounted on planet arms so as to revolve on their own axes and have orbital revolution with respect to the sun stator. | 09-05-2013 |
20130278103 | STATOR USED IN AN ELECTRICAL MOTOR OR GENERATOR WITH LOW LOSS MAGNETIC MATERIAL AND METHOD OF MANUFACTURING A STATOR - A stator for an electrical motor or generator and method for manufacturing such stator includes providing a plurality of teeth and joining the teeth with a yoke. An electrically conductive winding is applied around each of the teeth. The teeth and/or yoke may be made from a stack of low-loss magnetic material sheets. The teeth and/or yoke may be made by folding a stack of magnetic material sheets. | 10-24-2013 |
20130328431 | CYLINDRICAL ELECTROMAGNETIC ACTUATOR - A cylindrical-shape electromagnetic actuator comprising a plurality of pairs of magnets, the magnets of each pair being held at a distance from each other with an effective air gap formed therebetween for accommodating a coil structure; and a substantially cylindrical frame structure for supporting the pairs of magnets, the frame structure being configured such that substantially separate closed loop magnetic paths are provided for the respective pairs of magnets. | 12-12-2013 |
20140084727 | ELECTRICAL GENERATOR APPARATUS, SYSTEM, METHOD, AND APPLICATIONS - An electrical generator apparatus, an electrical generator system and a method for generating electricity while using the electrical generator apparatus or the electrical generator system each include at least one hollow tubular arc component (i.e., generally a hollow tubular ring), at least one coil winding surrounding the at least a portion of the at least one hollow tubular arc component and at least one magnet movably located within a bore within the at least one hollow tubular arc component to pass through the at least one coil winding. By effecting a relative motion of the at least one magnet with respect to the at least one coil winding, an electrical output may be generated at the terminals of the at least one coil winding. The electrical generator apparatus, system and method may be particularly useful in generating electricity from water wave motion when the electrical generator apparatus is housed within a watertight enclosure that may serve as a buoy enclosure. | 03-27-2014 |
