Year by year electrical power generators are becoming increasingly popular not only in private sector but on a bigger industrial scale. This is directly related to the savings in expenditures as well reduction of fossil fuels. But until now gasoline and diesel fuel remains to be the most widely used power source. The decomposition substances of such fossil fuels are toxic and cause environmental pollution.
This is where fuel free generators came as a solution, offering a range of advantages comparing to the common fuel powered generators.
Back in 2006 Andrii Slobodyan started to research and develop magnetic generators with the purpose of effective power delivery for energy consumers.
The device consists of the driver, a stator, carrying permanent neodymium magnets, a rotor with permanent magnets, a shaft, bearings and screens. The design of the device allows to switch magnets polarity in the magnetic field based on the specific magnets alignment.
Whit the interaction of the opposite poles of the stator magnets and the rotor, the rotor magnet is attracted by the stator magnet, turning the rotor at a certain angle until the opposite poles of the stator and rotor magnets coincide.
As the rotor enters the “dead zone” and the motor shaft load increases, magnets polarities are switched, followed by the rotor magnet being pushed out of the stator magnet and the rotation speed of the rotor being increased, providing for continuous rotation. The engine is stopped and started by using external force. Rotation speed depends on magnets diameter and strength.
Though some force still should have been applied to switch magnets polarity, such polarity switch required only 70% of the repulsion and attraction force.
The device was not equipped with any software making it uncontrollable and unable to generate useful power for consumers. Although the device did not allow for useful power generation, some valuable data was collected for understanding of the principles of magnetic generators operation.
This principle of operation formed the basis for the creation of a generator that worked on the interaction of permanent magnets and bifilar coils.
A bifilar coil is an electromagnetic coil that contains two closely spaced parallel windings and a series connection counter coil. In order to properly increase the coil power, its turns are wound in such a way, so as to provide the greatest potential difference between adjacent turns or spirals. The energy stored in the coil is proportional to the square of the potential difference between adjacent turns.
Due to the special folded tape-like shape of the coil, capacity for a set value of the potential difference between turns could be enhanced significantly. If the potential difference between coil ends is 100 volts with the coil of 1000 turns, then the potential difference between any of the other nearest adjacent turns would be calculated as equal to 0,1 volts (100/1000).
When coil winding is placed in parallel and isolated from conductor, with its end connected to its origin and the length of both conductors being set at the level so as to provide the total amount quantity of turns and spirals equal to 1000, then the potential difference between any adjacent points, as considered above, will be just the same as between conductors, equal 50 volts. The capacity is proportional to the square of the potential difference between adjacent turns and the total energy stored in the coil of this structure will be enhanced by 250000 times (= 50/0,1 squared). The potential difference allows to get enough capacity to suppress self-induction, generated by all types of currents, which, in turn, can be transformed into usable electrical energy that can be eventually utilized by the end user.
An additional advantage of such capacity generation is in its uniform distribution, what is crucial in terms of efficiency and cost effectiveness. Such capacity can be easily enhanced by changing the shape and size of the coils while keeping the potential difference and current frequency at the same level.
As a result of endless efforts and trials, Andrii Slobodyan (chief engineer) has found the way to arrange bifilar coils connection in such an order, wo as to allow the device to maintain its RPM for an unlimited time regardless of net energy being consumed.
A demo prototype, for bifilar coils work demonstration has been created. Small power LED lamps were connected to the prototype as basic load. Each coil winding was connected in series of two circuits, so that the induced impulse of each winding was combined.
The two coils were aligned with the precise angle, so as to avoid the direction of the induced EMF, coinciding with the rest of coils. Within such construction the current flows from the nearby coil creating the magnetic field and attracting the same name polar side. Initial start of the device was performed manually by a gentle push with no other actions required to keep the non-stop operation.
The purpose of the invention was to increase the power by reducing rotor resistance to bifilar coils, with no back EMF generated with the rotation of the rotor with magnets.
However, the device was not applied or further developed at that time turning the efforts of the Infinity SAV’s team to different projects development.
Since 2013 Andrii Slobodyan has been working on the improvement of magnetic generator, using bifilar coils principle. As a result, a small prototype of 1kW/h power capacity has been developed.
The prototype capacity depended on the internal rotor drum rotation speed with the maximum possible speed of 6000 RPM. The drum of the Magnetic Generator consists of a rotor and a shaft with permanent magnets, uniformly situated along the circumference of the rotor with the same-name and opposite polar poles. While the stator contains 55 copper-wired bifilar coils, which are situated along the circumference of the stator in the same way and quantity of permanent magnets on the rotor.
Power is generated in the device by interaction of permanent magnets with bifilar coils and an emerging electromagnetic force between them. The magnets and coils are directed towards each other to create torque on the rotor.
The designed software of the generator enables for monitoring and effective control of the rotor when running on-load or no-load mode.
In 2016 Infinity SAV’s team under the supervision of Andrii Slobodyan as a chief engineer, has developed an advanced prototype of the magnetic generator with the power capacity up to 10kW/h.
This new model fixed errors and shortcomings of all previous models. This project took plenty of the Company’s own resources and efforts of dozen specialists, engineers, designers, software programmers and project developers to bring it to success. The device is able to operate in autonomous mode and maintain its RPM regardless of amount of useful energy being consumed.
The main components of the generator: stator, bifilar coils (placed inside the stator with the same-name and opposite polar poles); rotor with a shaft, permanent magnets (placed at the outer side with the same name and opposite polar poles); bearings.
The magnetic generator MG10 consists of 250 neodymium magnets and 250 bifilar coils. The constructional feature that enables generating electrical energy is the precise angular alignment of the coils and magnets inside the drum and the switching regulations to suppress back EMF and effectively collect accumulated energy inside the electromagnets (coils).
As a magnet starts approaching a coil, at a certain point the voltage of the coil increases along with the amount of charge it can transfer. Once the switching regulator detects the maximum voltage of the coil, it switches off the coil. The magnetic field of the coil that has been formed after excitation of the coil will tend to collapse generating a back EMF in the coil windings.
Our software specialists have developed programming language and algorithms to enable work of the generator’s control system.
This unique software is able to suppress the parasitic current and transform it into usable electrical energy that can be utilized by the end user.
The device has been tested during 6 months with the non-stop operation of 2 weeks.
In the next 2 years the device was improved and upgraded in terms of design, configuration and software.
This original prototype served as a model to launch batch production of magnetic generators.
