Description

Reverse Pulsed Lead-Out Electric MOTOR/Generator

BACKGROUND OF THE INVENTION 1. Field of Invention

The present invention relates to a motor/generator configured and arranged to change its magnetic polarities between a stator and a rotor and lead-out the embedded magnetic flux into energy thereof.

2. Background Information

Life without electricity is unimaginable. Since the invention of electricity, man has been researching ways to use alternate energy. Solar energy and wind energy were developed, but were not always able to supply or meet the requirements of the small family. A new alternative source of energy was discovered using a magnetic reverse pulsed lead-out generator motor and the physics of motion.

Although there are different alternative energy sources being used today, the main difference is the origin of how the energy is produced. In a magnetic reverse pulsed lead-out generator motor the source of energy is lead-out from the force of the magnets which helps the core of the generator to spin and supply continuous energy.

A similar theory is applied on the Shanghai Maglev Train or Shanghai Transrapid, Shanghai, China. Keeping the train afloat and the acceleration being applied to the train is from the magnetic field which is created between the tracks and the train.

The lead-out energy magnetic reverse pulsed lead-out generator motor is able to induce electrical voltage. In this modern world of technology, people are always finding new things to replace the old. Before the invention of a lead-out energy magnet generator the sources were limited to gasoline, fuel, solar panels, tidal turbines/generators, and windmills.

This Patent Application discloses a magnetic reverse pulsed lead-out energy motor/generator having a plurality of permanent magnets provided in a rotor thereof. In such motor/generator, the induced voltage tends to become high when the motor/generator rotates at high speeds. Thus, in the motor/generator disclosed is configured and arranged to control the induced voltage from becoming high by tuning the pulsation of voltage in the coils of a stator and the rotor when the rotor rotates at high speeds.

More specifically, the magnetic reverse pulsed lead-out energy motor/generator disclosed includes the rotor, the stator having a plurality of coils, a magnetic polarity changing electronic circuitry mechanism and an actuator. The conventional motor/generator is configured and arranged to generate a magnetic field when the coils of the stator are energized with an electric current such that the rotor is driven by using the magnetic field. The magnetic resistance changing circuitry mechanism is configured and arranged to change the magnetic polarity between the stator and the rotor by changing the composite pulse between the stator and the rotor. The actuator is configured and arranged to actuate the magnetic polarity changing mechanism in accordance with an operating state of the motor/generator.

In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for a control circuitry. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.

The magnetic reverse pulsed lead-out generator motor uses the laws of physics by producing motion energy. This energy is lead-out with the help of the magnets and coils present in the generator which keeps the machine running. The lifespan of magnetic reverse pulsed lead-out generator motor machines has been calculated to be around 40 years or until the major components and magnetic strength of the magnets reduced naturally to inoperable state.

As an alternate source of energy, the magnetic reverse pulsed lead-out generator motor has proven to be environment friendly and does not emit any harmful gases. People who are environment conscious can use the free energy device without having any kind of guilt.

Another added bonus of using the magnetic reverse pulsed lead-out generator motor is the cost efficiency. By producing energy to operate an entire household, it will reduce and possibly even eliminate the expense of electric bill. Unlike other sources of energy which may be limited on the amount of watts they are able to produce, the magnetic perpetual motion generator is able to produce thousands of watts of energy by scaling designs.

The magnetic reverse pulsed lead-out generator motor has a bright future since the device provides a cheap way to produce energy, helps lower your electricity bill and helps reduce pollution.

The first rotor member is configured and arranged to be rotated with respect to the stator using the first magnetic field. The magnetic polarity changing circuitry mechanism is configured and arranged to change a magnetic polarity between the stator and the first rotor member using the second magnetic field.
