Description

Maglev generator

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an engine, and more particularly to a magnetic floating generator capable of achieving high-efficiency power generation by virtue of low loss characteristics of a magnetic floating state.

About the mid-18th century, the European continent launched an industrial revolution that changed the lives of all human beings. People began to explore the application devices and methods for the exchange of energy and mechanical energy. However, to this day, as fossil fuels such as coal mines and oil have gradually revealed the problem of stocks, and following the environmental pollution and climate change caused by industrial development, all countries in the world are actively seeking various clean alternative energy sources to enable human civilization. Sustainable development, especially electrical energy is the most important energy demand in modern life, so people have developed mechanical generators that convert mechanical energy input into electrical energy output.

The electromagnetic rotor 11 is wound with a plurality of coils 12, and the two arcuate magnets 10 are disposed opposite each other for generating a magnetic flux. A rotating space is formed between the two arcuate magnets 10, and the electromagnetic rotor 11 is supported by a shaft center 13. A bracket (not shown in the drawings) supporting the shaft 13 is disposed within the rotating space for performing a rotating motion in the rotating space. When a mechanical generator is used, a mechanical energy (such as a torsion) can be applied to the shaft 13 by the outside (for example, a user's hand) to rotate the electromagnetic rotor 11 in the rotating space between the two curved magnets 10. At this time, according to Faraday's law, the complex coil 12 on the electromagnetic rotor 11 can generate electric energy by sensing the change of the magnetic flux in the space, and then the user can extract and output the electric energy, that is, Achieve the purpose of converting mechanical energy into electrical energy.

However, the electromagnetic rotor 11 can be disposed between the two permanent magnets by the shaft 13 and the bracket, but the friction between the shaft 13 and the bracket when the electromagnet rotates, so the machine is mechanical. The process of inputting to conversion to electrical energy output will cause a large amount of energy (such as thermal energy) loss, which not only makes energy conversion efficiency and utilization low, but also long-term mechanical friction will cause material loss and make the whole operation. The attenuation of the life span; on the other hand, the mechanical generator of the prior art is affected by the friction force, so when the torque is applied to the shaft 13 is stopped, the electromagnetic rotor 11 stops rotating, so that the plural number on the electromagnetic rotor 11 The coil 12 can no longer generate electrical energy by varying the magnetic flux of the sensing space.

Therefore, it is proposed that the device has the characteristics of low energy or/and mass loss and high energy conversion efficiency, and is a technical problem that various circles are currently trying to solve.

In view of the above-mentioned shortcomings of the prior art, the present invention provides a magnetic levitation generator which has the advantage of the frictionless force of magnetic levitation, so that the energy loss is minimized, and the user does not need to continuously apply mechanical energy from the outside. It can achieve the purpose of continuous power generation, with the characteristics of labor saving and long-term operation.

Preferably, the stator may have a short cylindrical shape and has a circular arc-shaped cylindrical surface, and the plurality of first magnets may be equally spaced on the cylindrical surface of the stator.

Preferably, the rotor can have a cylindrical shape, and a magnetic floating space can be formed inside the stator, and the stator can be accommodated in the magnetic floating space of the rotor.

Preferably, each of the plurality of first magnets and each of the plurality of second magnets may be a permanent magnet.

Preferably, each of the plurality of first magnets and each of the plurality of second magnets may include a casing, a magnetic core and a retaining ring, one end of the magnetic core being receivable in the casing And the other end of the magnetic core can be sleeved.

Preferably, the magnetic pole directions of each of the plurality of second magnets are respectively opposite to each other The magnetic poles of each of the plurality of first magnets are opposite in direction.

Preferably, the plurality of coil sets and the plurality of first magnets are alternately arranged on the stator in an equally spaced manner.

When the invention is initially used, the plurality of coil sets are energized such that the plurality of coil sets respectively generate a magnetic flux, and the plurality of second magnets on the rotor induce a change in the magnetic flux of the plurality of coil sets to cause the rotor to start rotating. Then, the plurality of coil sets are powered off, and the plurality of coil sets continue to sense the magnetic flux change caused by the plurality of second magnets to generate electric energy; since the rotor and the stator are in a non-contact maglev state, that is, the rotor and the rotor There is no friction between the stators, so the user does not need to continue to work on the rotor from the outside to keep the rotor running for a long time, and achieve the purpose of long-term high-efficiency power generation; also because there is no rotor between the rotor and the stator. Friction, so there is no problem of material wear, so it has a better service life.
