INTRODUCTION
The purpose of this report is to reproduce the experimental work carried out between 1946 and 1956 by J. Searle , including geometry, the materials used and the technology of manufacturing the Searl- effect generator (SEG) .
The following information was obtained as a result of the author's personal contacts with Searle and should be considered as preliminary data, as further research and improvement may cause changes and additions to the content.
Design
The SEG consists of a main driving element called the Gyro-Cell (GC, ring) , and, depending on the purpose, the coils for generating electricity or the shaft for transferring mechanical work. The ring can also be used as a high voltage source. Another important property of the ring is the ability to levitate.
The generator can be considered as an electric motor consisting only of permanent magnets of a cylindrical shape and a fixed ring. In Fig. 1 shows a generator of the simplest form, consisting of a fixed annular magnet called a base, and a number of cylindrical magnets or rollers.
During operation, each roller rotates about its axis and simultaneously rotates around the base in such a way that a fixed point on the lateral surface of the roller describes a cycloid with an integer number of petals, as shown in phantom in Fig. 2 .
Measurements have shown that there is an electric potential in the radial direction. The base is charged positively, and the rollers are negative.
In principle, the generator does not need any reinforcement to maintain mechanical integrity, since the rollers are attracted to the ring. However, when using the generator for mechanical operation, shafts must be used for moment transfer. Moreover, if the generator is mounted in the casing, the rollers should be slightly shorter than the height of the base to prevent grazing against the casing or other parts.
In operation, gaps are created as a result of electromagnetic interaction between the ring and the rollers, preventing mechanical and galvanic contact between the base and the rollers and reducing friction to an insignificant amount.
Experiments have shown that the output power increases with the number of rollers and to achieve a smooth and reliable rotation, the ratio of the diameter of the base to the diameter of the roller must be a positive integer larger than 12 . Experiments have shown that the gaps between adjacent rollers should be equal to the diameter of the roller, as shown in Fig. 1 .
A more complex configuration can be formed by adding additional sections consisting of the main ring and the respective rollers.
Experiments have shown and that for stable operation all sections must be of the same mass.
CONFIGURATION OF MAGNETIC FIELDS
As a result of the magnetization process by a joint constant and alternating magnetic field, each magnet acquires a characteristic magnetic pattern located on two annular paths and consisting of a plurality of north and south poles, as shown in Fig. 4 .
The measurements showed that the poles are evenly spaced about 1 mm apart. And it was found that the density of poles per unit length of a circle should be constant, characteristic for a given generator, by a value.
Where: N (p) is the number of poles on the track of the base, N (r) is the number of poles on the roller track.
In addition, the distance between the two track poles of the base and the rollers should be the same for this generator.
The tracks of the poles allow automatic switching and thereby create a torque. How this is achieved is still unclear and requires further research. The source of energy is also unknown. And in the future exact mathematical relations between output power, speed, shape and mechanical and electromagnetic properties of materials should be established.
MAGNETIC MATERIALS
The magnets used in the original experiments were made from a mixture of two types of ferromagnetic powders purchased in the USA. A chemical analysis was carried out of one of these magnets that still exists, and the following components were found in it:
1. Aluminum- Al
2. Silicon- Si
3. Sulfur- S
4. Titanium- Ti
5. Neodymium - Nd
6. Iron - Fe
The spectrum is shown in Figure 5.
COUPLINGS OF INDUCTIVITY
If the Searl generator is designed to generate electricity, several coils must be connected to it. They are on C -shaped cores made of soft (Swedish) steel with high magnetic permeability.
The number of turns and the diameter of the wire depends on the destination. Figure 6 shows an approximate design.
PREPARATION METHOD
Figure 7 shows the main stages of the process of manufacturing magnets.
- Magnetic materials and binding agents [... missed in the original ...] ... that the raw materials were cheaper and more efficient than those used by Searl. The possibility that other binders can improve the characteristics of the device is not ruled out.
- Weighing. The main condition for manufacturing a quality magnet is observing the ratio of the amount of each substance in a ferromagnetic powder. This ratio is selected experimentally.
True, today it is already difficult to establish the composition used by Searle. In combination with new magnetic materials and improving the geometry of the generator, this is a broad area of application of the researchers' efforts.
It is important that the amount of binder is as small as possible to obtain the maximum density of magnets. However, it is possible that the binder takes an active part in creating the Searl effect. For example, the dielectric properties of the binder component can play a significant role in the electromagnetic interaction of the generator parts.
-
Mixing. This is an important process, on the thoroughness of which depends the uniformity and strength of the final product. High homogeneity can be achieved by blowing the mixture with a turbulent air flow.
It was experimentally established that the best result is obtained if all the elements of the same generator are made from the same portion of the components.
Molding. In the process of forming, a compound consisting of a ferromagnetic powder and a thermoplastic binder is pressed and simultaneously heated. Figure 8 shows the device used to produce blanks - rollers and a ring, not yet magnetized. When making large rings (more than 30 cm in diameter), you can make them from several segments that are connected after.
The data given below should be considered as indicative. Specific conditions are selected empirically for the maximum Searle effect.
1. Pressure: 200-400 bar .
2. Temperature: 150-200 degrees Celsius.
3. Molding time: not less than 20 minutes . Before removing the pressure, the workpiece must cool down.
5. Processing. This stage can be ruled out if the weighing and shaping are done carefully. However, it may be necessary to polish the cylindrical surfaces of the ring and rollers.
6. Control the size and cleanliness of surfaces.
7. Magnetization. The rollers and the ring are magnetized separately by placing them in a combined magnetic field composed of a constant and an alternating current and is performed in one cycle of turning on and off the current. Figure 9 illustrates the installation for magnetization.
The key serves for the simultaneous supply of DC and AC power. Figure 10 shows the dependence of the total magnetomotive force on time.
The magnetizing coil consists of two windings. The first is designed for direct current and contains about 200 turns of insulated copper wire. The second is wound from a bare copper wire on top of the first one and contains about 10 turns. Figure 11 shows the coils in a section and the dimensions are indicated.
Recommended parameters:
- constant current from 150 to 180 A
- alternating current (unknown)
- Frequency 1-3 MHz .
8. The purpose of this control operation is to verify the presence and proper arrangement of the two pole tracks. Measurements can be performed using a magnetic flux density meter and a set of reference magnets.
9. The assembly procedure depends on the destination. If the generator is designed to work as an engine, it must be mounted inside the housing and connected to the shaft. If as an electrogenerator - then electromagnets should be mounted.
