Description

NEW TYPES OF ELECTROMAGNETIC MACHINES

INSTEAD OF PARALLEL FIELDS.

GENERATOR ENGINES. SPECIFIC FREQUENCY.

General: The invention refers to new types of electromagnetic motors with general characteristics, their great energy efficiency, their high mechanical resistance in terms of construction, and their economic-ecological and technological revolution on a global scale, using them for the production of kinetic and electrical energy.

Historically: All electromagnetic motors to date: DC, Stepper, Alternating Current (Single-Phase, Three-Phase and Multi-Phase, etc.) are made to work on a general operating principle:

The rotor, regardless of the type of motor (permanent magnet direct current, inductive alternating current, short-circuited rotor, etc.) acts like a magnetic needle which tries to orient itself to the changing or rotating magnetic field of the motor's stator.

The rotor PASSIVELY follows the magnetic field of the stator, creating at the same time in the stator itself (due to construction) counter-exciting forces, as a result of which the motors can never overcome their own losses in efficiency, i.e. their efficiency is always less than 100 %, since the absorbed electrical energy required to drive the motor is always greater than the mechanical energy delivered to the shaft. For example, in a typical DC motor, whose induction drum has several coils connected in series, the back emfs of all these coils add up to form the motor back emf and it depends on the speed at which the conductors cross the magnetic lines of the state. That is, the rotation speed of the engine. When the motor is operating at rated load, its anti-emetic force varies between 80 and 95% of the voltage depending on the size of the motor.

CONCLUSIONS: If we didn't have anti-electrostatic forces, we would spend 5 to 20% of the voltage for the same load.

Also the magnetic force (FB) of existing motors is equal to the magnetic field B of the stator times the magnetic field of the rotor (L * I) where

L: effective conductor length and

I: Magnetizing current.

That is, it holds: FB= Β*L*I

That is, in existing motors, their rotational force is determined exclusively by the magnetic field of the stator (B) and the magnetic field of the rotor (L * I).

DESCRIPTION

NEW TYPES OF ELECTROMAGNETIC MACHINES

OF OPPOSITE FIELDS.

GENERATOR ENGINES. SPECIFIC FREQUENCY.

In the present invention the mentioned motors have a new principle of operation where the rotor is ACTIVE, i.e. it attracts and repels the magnetic fields of the stator and PASSIVE, i.e. it is simultaneously attracted and repelled by the magnetic fields of the stator. That is, at any moment of operation of the new motors, each pole separately, either stator or rotor, is ACTIVE and PASSIVE AT THE SAME TIME. So the mechanical forces are times 4.

The operating principle of the new motors is focused on their construction in terms of the generated magnetic fields that cause it to rotate.

Particularly:

Anti-parallel fields: The new type of anti-parallel field motors are named so precisely because the fields of the stator-rotor that we create for the rotation are parallel to each other. Generator motors and self-frequency motors belong to this category.

1. C internal motors: They are anti-parallel field motors that during their operation create an electroexciting force (HED) that contributes positively to the energy required for their rotation, resulting in a total reduction of energy consumption for their operation. That is, not only are anti-electro-exciting forces not created, but additionally electro-exciting positive forces are created in terms of the forces that cause them. That is why we call them generator engines because during their operation they work simultaneously as engines and as generators. They consist of a stator of electromagnets and a rotor of permanent magnets or electromagnets placed alternately, that is (B-N , B-N). That is, by giving mechanical energy to the shaft of the machine we have an alternating current generator. For example, a new type of motor with a stator consisting of 20 poles of electromagnets and 20 poles of permanent magnets in the rotor if mechanically rotated at a speed of 300 revolutions per minute, we will get an alternating voltage of frequency 50Hz.

2. Natural frequency: They are anti-parallel field motors and they are generator motors with an additional property. They are permanently connected with a capacitor arrangement so that the inductive resistance of the motor (Total resistance of the coils of XL) is equal to the capacitive resistance of the capacitor Xc. So that we have coordination. That is, the machine behaves as a THOMSON MACHINE. Its rotational speed

engine is given by the relationship They are engines that do not

they need power to operate as the rotating motor acts as a generator by charging the connected capacitor. The capacitor discharges back into the coils which now act as motor coils. So the engine has constant revolutions at a certain load.

DETAILED CONSTRUCTION AND OPERATING CHARACTERISTICS

ELECTROMAGNETIC MACHINES

In the new types of electromagnetic machines we take advantage of their geometric construction. The performance of new electromagnetic motors depends on the carrying force F of its electromagnets or magnets.

Their geometric construction, i.e. the diameter D of the motor, and the number of pole pairs (ν), acting on the rotational forces.

That is, we have: P = F * d * ν

Where : P is the motor power

F is the Coulomb force F= (m1* m2) / α<2>

d is the diameter of the motor rotor

n is the number of pole pairs

This is how the external appearance of the new engines changes, they are mostly discoid (flat) engines taking advantage of d and n. And not narrow along the axis (BIi). The last but important factor in the performance of new engines is their construction materials. That is, as far as electromagnet materials are concerned, they should have high magnetic permeability μr, small coherent field Hc, and high magnetization T.

If we refer to permanent magnet materials, the magnets must have a high Βr (permanent magnetism) and a large Hc (coherent field), i.e. they must not be demagnetized. The rotational force of each engine and by extension their torque also depends on the construction materials.

Therefore, the general technical characteristics of the new types of electromagnetic machines are:

1. The way of creating the magnetic fields that interact with each other for the rotation.

2. The geometric construction of the engines.

3. The construction materials of the engines.
