Abstract:
The paper presents a system to produce electrical power consists in a permanent magnet generator or motor with stationary coils placed in a circle, with a rotor on which are placed permanent magnets and a carousel which is carrying corresponding groups of permanent magnets to the centers of the already specified coils. The carousel is moving in tandem with the rotor by virtue, since those 2 moving parts are magnetically coupled, one with the each other.
Sensors and logical electrical devices are needed as well, sensors in order to let the electrical devices know the location of the moving parts in relationship with the coils. The logical electrical devices will turn power into different coils on and off, depending on where the moving (rotary and carousel) parts are, compared with the location of the stationary coils.
The carousel is initially rotated manually, the entire system will start to spin and also to turn the power in coils on and off, in order to increase the speed of the carousel/rotor and to minimize the friction and the other forces which oppose to the carousel’s rotating movement. The speed is increased by using the properties of the interactions between permanent magnets and coils. The coils are basically generating magnetic fields around them, hence, the arrangement of the groups of permanent magnets and their poles has to be done in relationship with the instant magnetic poles, so the speed of the carousel can be increased and maintain.
The system is using electrical power (but only episodically) in order to maintain the high speed of the carousel, and the movement of the carousel is producing more mechanical work when compared with the energy used to maintain the movement of the carousel. This is happening due to the potential energy which is stored within magnets. This system has a limited life, since all the magnets are losing between 1% and 6% of their magnetic power per year.
A very similar idea was patented in US in 1997(the request for it was made in 1994) within publication of US5625241A and patent number is 5625241 from 29th of April 1997. The patent is now expired but it is not widely used. The aim of this project is to rebuild the generator, observe its limitations and to try to use it as an alternative electric generator.
