Принадлежит: Общество с ограниченной ответственностью "ЗЕТТА"

Полезная модель относится к области машиностроения и может быть использована в качестве силового агрегата как стационарных, так и транспортных машин, в частности автомобилей с гибридной силовой установкой, имеющих двигатель внутреннего сгорания, асинхронный малошумный двигатель и систему управления ими, включающую преобразователи, и может быть использована в различных областях техники, например, в качестве силовой установки в таких транспортных средствах, как скутера, мотоциклы, квадроциклы, снегоходы и катера.Гибридный силовой агрегат содержит двигатель внутреннего сгорания и электродвигатель, механически связанные друг с другом и с колесами, при этом электродвигатель состоит из ротора, интегрированного или жестко посаженного на выходной вал двигателя внутреннего сгорания, статора, жестко закрепленного внутри ротора, системы управления асинхронным двигателем, образуемой статором и ротором, интегрированным с двигателем внутреннего сгорания, где статор и ротор имеют обмотки, собранные одна в звезду, другая в треугольник, большего, чем у стандартного двигателя с одной обмоткой, числа фаз и сложения магнитных полей этих двух обмоток, которые приводят к тому, что такой асинхронный двигатель характеризуется более «гладкой» и близкой к синусоиде кривой М.Д.С. Использование полезной модели позволяет создать силовой агрегат на основе двигателя внутреннего сгорания и асинхронного малошумного электродвигателя с системой управления, обеспечивающего высокий КПД и оптимальные режимы работы во всех режимах движения транспортного средства, а также снизить массогабаритные показатели и механические потери отбора энергии для зарядки накопителя энергии.

A method for the providing and generation of constant motive power for electric vehicles to travel on roads uninterruptedly using high voltage alternator and transformers/substation—step-up transformers and/or step-down down transformers to appropriate desirable is disclosed. The present invention presents the idea of using a combination of a high voltage alternating circuit induction motor and a step-down transformer and their embodiments to step the voltage down to more desirable and useable level of volts depending on the capacity/size for a continuous supply of electricity for electric vehicles. The present invention allows electric vehicles to operate without distance limitation or battery pack losing power and whose disposal is an environmental hazard apart from cutting or reducing greenhouse gas as few or there will be no more mass production of internal combustion engines. The present invention uses high voltage from an alternator whose voltage is increased by a step-up transformer then goes through a substation and this power is decreased by a step-down transformer so that a lower voltage powers electric vehicle of all sizes/capacity. The summary is that when the power is passed through the step-up transformer, the primary side has few turns of wire; and the voltage decreases; and current is increased; but in the secondary side, with more turns of wire, the voltage increases but the current is decreased. In the case of the step-down transformer, the voltage is increased in the primary side with many turns of coils, but on the secondary side with few turns of coils, the voltage is decreased, and the current is increased, thus giving the vehicle power to operate. 1.

INLINE ACTUATED HORIZONTAL PENDULUM ENERGY HARVESTING GENERATOR AND BATTERY-FREE WIRELESS REMOTE SWITCHING SYSTEM

Номер: US20220069690A1
Автор: Deak, SR. David
Принадлежит:

The present disclosure is of energy harvesting generators producing power to electrical loads by a novel method of the inline triggering of a horizontal pendulum that vertically oscillates for an established time duration. The horizontal pendulum component has disposed and fixed, a magnet whose travel is under the direct influence of the motion of the pendulum component. This oscillation of the pendulum and its disposed magnet is situated proximal to an electrical coil that has disposed a magnet enclosure with a disposed magnet that is in the center of the coil arrangement. The instant triggering is accomplished by a novel trigger whose end has a first trigger tooth that upon an external applied force comes in contact with a second trigger tooth that forces the pendulum downward beyond it release position to allow the pendulum and magnet to freely oscillate. Converse action occurs when the triggering force is instantly removed. 1. An electrical generator configured to convert mechanical kinetic energy into electrical energy , wherein the electrical generator comprising;an enclosure with a cover;a coil winding about a coil bobbin, said coil winding having terminals;at least one trigger plunger that is utilized as an operational trigger mechanism;at least one rotatable pendulum having a first magnet affixed thereto;and said rotatable pendulum being mounted for rotation relative to said coil; andsaid rotatable pendulum being is configured to receive said kinetic energy from said trigger plunger as said trigger plunger periodically comes in kinetic mechanical communication with said rotatable pendulum;and wherein there is disposed a second magnet that is disposed within the center of said coil bobbin that is in attractive magnetic cooperation with said rotatable pendulum and said first magnet;and wherein said rotatable pendulum and said first magnet are configured to magnetically interact with said second magnet such that said rotation of said pendulum with its first ...
