A power system for an aircraft engine provides rotational drive to propeller driven and turbofan jet engine powered aircraft by use of a propeller or fan drive motor. Electrical power is provided to the drive motor by a high efficiency electrical power generator with reduced electromagnetic drag or reverse torque. The electric generator utilizes a solid state rotor that does not rotate which allows for power generation without reverse torque or the usual energy required to rotate the rotor inside the stator of the generator. Only the magnetic poles of the disclosed rotor rotate to generate the power. The fan blades of the turbofan jet engine are driven by the electric drive motor in which the rotor is a part of the fan as well as the drive from the high pressure turbine.

Apparatuses, systems, and methods of use for a magnetic coupling device is disclosed. The magnetic device may have a plurality of magnets to create a magnetic field to the devices enclosed within the device. The coupling device may have a housing that encloses and/or partially surrounds one or more rotatable shafts. The coupling device may couple an output shaft from a motor to an input shaft of a generator. The coupling device may have an electric coil that when energized may vary any applied magnetic field to the rotatable shafts. The magnetic device may have a first plurality of magnets positioned at a first radial position and a second plurality of magnets positioned at a second radial position, with the first magnets being rotatable and the second magnets being stationary. Multiple magnetic coupling devices may be coupled together in series to provide increased magnetic fields to the enclosed system.

The invention provides a power generation method and a system equipped with energy storage and energy release accommodation mechanism. By using an energy storage and energy release accommodation system arranged in the system, the generator set at an end of the system can immediately supplement energy from an energy storage unit after providing electric energy to a load, so that the output energy will not drop suddenly, while still stably maintaining both the rated energy output and the system operation.

The invention relates to an energy efficient induction motor (100) comprising a stator (102), a main winding (M) of the stator (102) for generating a rotating magnetic field (RMF) (108), and a rotor (104) disposed to rotate relative to the main winding (M) of the stator (102) due to the RMF (108). The stator (102) comprises additional winding(s) (A) for producing an alternating EMF (110) which is induced in the one or more additional windings (A) due to the rotation of the rotor (104). The alternating EMF (110) produced in the one or more additional windings (A) is fed back simultaneously to the main winding (M) of the stator (102) throughout the complete rotation cycle of the rotor (104) through an electronic control unit (112) coupled to the stator (102), producing a resultant AC output power (116) that is fed continuously to the main winding (M) of the stator (102).

Provided herein is a system for generating electrical current comprising a transducer subsystem having an upper end and a lower end, the transducer subsystem generating electrical current responsive to objects being dropped individually from an array of the objects at the upper end of the transducer subsystem to the lower end of the transducer subsystem under the influence of gravity; and a return subsystem for receiving the objects of the array and for returning the objects of the array from the lower end to the upper end using upthrust through a fluid body, wherein the return subsystem is configured to permit physical interaction by a user with the return subsystem, wherein a physical interaction with the return subsystem by the user can cause the return subsystem to move fluid collectively in respect of multiple, or in respect of all, objects of the array.

A power transmission assembly includes a base, a rotating frame rotatably coupled to the base and configured to rotate about an axis, an output shaft coupled to the rotating frame, a weight selectively repositionable relative to the rotating frame, and a weight actuator configured to reposition the weight relative to the rotating frame to move the weight from a subtraction position located at a first height to an addition position located at a second height. The second height is greater than the first height such that a gravitational force on the weight drives the rotating frame to rotate about the axis and drive the output shaft.

An internal combustion engine has a crankshaft with at least one throw being formed as a complete disc over at least a portion of its thickness. Permanent magnets are attached to the disc of the at least one throw in an annular array. Electromagnets are attached to the engine block, a brace coupled to the engine block, and/or an oil pan mounted to the engine block. The brace may include one or more circular structures surrounding the discs of the throws, and may support the electromagnets. The electromagnets are positioned opposite the permanent magnets. A control system selectively provides electrical current to the electromagnets to affect the motion of the crankshaft, and may further selectively activate and deactivate at least one of the cylinders by stopping fuel flow, spark, and/or intake valve actuation.
