Description

The present invention relates to improvements in dynamos, alternators and electric motors, and more particularly to improve the efficiency thereof.

According to the present invention there is provided a dynamo, alternator or electric motor comprising an annular stator and an annular rotor which rotates within the stator, said rotor and stator each being made up from an equal number of radially spaced segments, each segment, in use, forming a magnet across its radial faces, and wherein the magnetic face of one segment is of opposite polarity to the adjacent face of the adjacent segment at any moment in time.

The stator and rotor segments may both be electromagnets, or one of said rotor or stator segments may be permanent magnets and the other electromagnets.

Preferably the spaces between each segment contain insulating material to insulate the magnetic field from one segment from the magnetic field of the adjacent segment.

An embodiment of the present invention will now be described with reference to the accompanying drawing.

Referring to the drawing there is shown a cross section view of the stator and rotor of an electric motor, alternator or dynamo. The stator 1 is composed of twelve radially spaced segments "A to L". The rotor 2 is composed of twelve radially spaced segments "a to 1". Rotor 2 will normally be supported at either end of its axial length by bearings (not shown) to rotate within the stator 1.

Each segment, in use, forms a magnet, either in the form of a permanent magnet or an electromagnet or inductance magnet. The magnet is formed across the radial faces of each segment (faces 3x and 3y in segment "A") so that the two radial faces of each segment are of opposite polarity (i.e.

face 3x is "north" and face 3y is "south"). Also the segments are magnetically aligned so that the radial face of one segment is of opposite polarity to the adjacent radial face of the adjacent segment. Looking at segments A and B, radial face 3y of segment A is "south" and its adjacent face 4x of adjacent segment B is "north". Thus both the stator 1 and rotor 2 effectively both form a circle of equal number of sequentially aligned magnets.

A space 5 exists between each segment in the stator, and a space 6 exists between each segment in the rotor. This space will normally be filled with magnetically insulating material (not shown).

Consider now the invention in the form of an electric motor. The stator segments will either be permanent magnets or electromagnets. The rotor segments will be electromagnets in the form of coils which receive current through suitable brushes acting on slip rings as is known in the art.

The motor will have increased power compared to existing electrical motors because it works on the scientific and physical principles of self inducing kinetics and in-built natural kinetics. This is effected through electromagmentic attraction and repulsion as the rotor rotates. As the rotor rotates it will move through nodes or zones of electromagnetic repulsion/compression and nodes or zones of electromagnetic attraction/vacuum induction. This same effect is achieved if the invention is used as an alternator or dynamo.

Where the segments are in the form of electromagnets or coils, these can be wired to receive a source of electricity (in the case of a motor) or supply a source of electricity (in the case of an alternator or dynamo). With the rotor this can be done through slip rings or commutator split rings. With the stator this can be done through separate positive and negative terminals or through positive or negative terminals gathered together. In this respect the invention can be AC or DC depending on how it is wired.

These details will be apparent to those skilled in the art.

The invention need not be limited to twelve or an even number of segments, all that is necessary is that the number of segment on the stator is the same as on the rotor.

Further modifications of the invention will be apparent to those skilled in the art without departing from the scope of the present invention.

1. A dynamo, alternator or electric motor comprising an annular stator and an annular rotor which rotates within the stator, said rotor and stator each being made up from an equal number of radially spaced segments, each segment, in use, forming a magnet across its radial faces, and wherein the magnetic face of one segment is of opposite polarity to the adjacent face of the adjacent segment at any moment in time, the spaces between each segment containing insulating material to insulate the magnetic field from one segment from the magnetic field of the adjacent segment, all as shown in Figure 1.

2. A dynamo, alternator or electric motor as claimed in Claim 1, wherein the stator and rotor segments being both electromagnets, or one of said rotor or stator segments being permanent magnets and the other electromagnets, all as shown in Figure 1.

3. A dynamo, alternator or electric motor as claimed in Claim 1 or Claim 2, wherein the stator 1 is composed of twelve radially spaced and segments "A to L". The rotor 2 is composed of twelve radially spaced segments "a to 1". Rotor 2 will normally be supported at either end of its axial length by bearings (not shown) to rotate within the stator 1.

Each segment, in use, forms a magnet, either in the form of a permanent magnet or an electromagnet or inductance magnet. The magnet is formed across the radial faces of each segment (faces 3x and 3y in segment "A") so that the two radial faces of each segment are of opposite polarity (i.e. face 3x is "north" and face 3y is "south").

Also the segments are magnetically aligned so that the radial face of one segment is of opposite polarity to the adjacent radial face of the adjacent segment. Looking at segments and B, radial face 3y of segment A is "south" and its adjacent face 4x of adjacent segment B is "north". Thus both the stator 1 and rotor 2 effectively both form a circle of equal number of sequentially aligned magnets.

Where the segments are in the form of electromagnets or coils, these can be wired to receive a source of electricity (in the case of a motor) or supply a source of electricity (in the case of an alternator or dynamo). With the rotor this can be done through slip rings or commutator split rings. With the stator this can be done through separate positive and negative terminals or through positive or negative terminals gathered together. In this respect the invention can be AC or DC depending on how it is wired. These details will be apparent to those skilled in the art.
