Description

ELECTR I C ITY POWER SO U RC E

This invention relates to an electr icity power source .

K nown electric generators comprise a series of looped conductors which are rotated within a magnetic field . This rotation is powered by a secondary power source such as a steam or water turbine which is usually mounted on the same shaft as the conductors .

These generators need a continual secondary power source to operate . Once that continual power source has been removed then electricity generation ceases . These known generators are not particularly efficient and much energy is lost for example owing to friction at the mountings for the rotating body .

The present i nvention has been made from a consideration of this .

According to the present invention there is prov ided an electricity power source in which electricity is provided via relative motion between a conductor and a magnetic field , characterised in that the power source comprises a rotatable body mounted on a track via at least one mounti ng member , and at least a part of the track and at least a part of the mounting member are adapted to form the opposite poles of a magnetic field . I n a preferred embodiment of the invention an initial secondary power source is provided which is adapted to power the rotation of the rotatable body for a certain initial period of time . The track and mounting members are opposite poles of an electromagnet. Alternatively the track and mounting members are opposite poles of a permanent magnet . The initial secondary power source comprises a turbine and may provide a series of pulses of power once the provision of power for the certain initial period of time has ceased . A plurality of similar electricity power sources may be provided , at least one of the electricity power sources being at least partially powered by one of the other electricity power sources . The electricity generators may be located within a vacuum . Isolators may be fitted to the track .

I n order that the invention may be more readily understood specific embodiments thereof will now be described by way of example only with reference to the accompanying drawings in which : -

Figure 1 is a diagrammatic illustration of one embodiment of the present invention ; -

Figure 2 is a plan view of the embodiment of Figure 1 ;

Figure 3 is a diagrammatic view of the electric generator of Figure 1 in combination with a series of similar generators ; and Figure 4 is a perspective view of a second embodiment of the invention .

Referring to Figures 1 to 3 an electrical generator 12 comprises a series of looped conductors 22 , 24 , 26 mounted on a rotatable armature 28. The armature 28 is located with a magnetic field (not shown) .

The armature 28 is mounted on a plurality of arms 40. The arms 40 are mounted on tracks 42 and are rotatably movable around the tracks 42. The free ends 41 of arms 40 and track 42 form opposite poles of an electromagnet such that when the electromagnet is energised the arms 40 rise above the track 42.

Once the electromagnet is energised the armature 28 is then rotated between the fixed magnetic poles 30 to 35. This rotation is powered by water turbine 10 in a conventional manner for a certain initial period of time. Once the armature 28 is rotating the turbine is deactivated and the armature 28 continues to rotate. As the arms 40 are not in contact with the track 42 there is little frictional resistance and the armature 28 can rotate freely between the fixed magnetic poles 30 to 35. Optionally the armature 28 may be located in a vacuum to reduce air resistance .

A periodic flow of electricity is produced in the loop type conductors as a result of the periodic variation of the flux of - _i}_

the magnetic lines of force passing through the loops. The alternating current produced by the generator is taken direct from the loops via current collectors such as brushes (not illustrated) .

At least some of the alternating current produced by the generator 1 2 may be rectified to provide a direct current and supplied to other similar generators 14, 16, 18, 20 in order to rotate the armatures thereof as shown in Figure 3 . The direct current needed to rotate the armature 28 is fed by means of slip rings and carbon or copper mesh brushes . Once these other similar generators 14 to 20 are in operation at least some of the alternating current produced therefrom can be used to power one another in the manner described above.

In this instance the turbine 10 can be disconnected from generators 12 to 20 once an equilibrium has been established in that all of the generators 12 to 20 are being powered by at least one other generator 1 2 to 20.

The turbine 1 0 may provide a series of pulses of power once the provision of power for the certain initial period of time has ceased .

The excess power supplied by the generators 12 to 20 can be used to power any electrically operated device . Referring to Figure 4 an electricity generator 50 is similar to that prev iously described except that only one track 42 and one set of arms are used to support the armature 28. The armature 28 is secured to the floor via a bolt 52 passing through the plate 54.

It is to be understood that the above described embodiment is by way of illustration only and that many modifications and variations are possible .

For example although in the above described embodiment the conductors are rotated within a stationery magnetic field , alternatively the magnetic field may be rotated around stationery conductors .

The magnetic field may be supplied by permanent or electromagnets . The electromagnets may be powered by at least one of the generators 1 2 to 20.

Also the electromagnet formed by the arms 40 and track 42 may be powered by the electric generator .

I solators may be fitted to the track .

The electrical power source may be used to generate electricity in a power station for industrial and domestic use. A lternatively the power source may generate energy for any means for transportation such as ships, cars , wagons , trains, aeroplanes or any moving vehicle.
