Abstract

The invention refers to an electric motor driven through the electric field. The electric motor has an insulating plate (3) and an insulating stand (1), on which there is a thin sheet of conducting material (2). A metal ring (5) is placed on the superior plate of glass (3) which touches the glass surface on three points (11). Between the metal ring (5) and the aluminum thin sheet (2) an electric field is realized by applying a high-tension source (ST). In the interior of the ring there is the rotor. The number of the rotor's arms can be arbitrary from 1 to n; where n is the whole and positive number. The rotor is formatted by an immobile bearing (8), in which interior there is an axle (9), in which are fixed the rotor's arms (7). At the extremity of the arms is a counter-weight (6) (one counter-weight for one arm) realized by an insulating material and also there is a fork with (10) a ball (4) in its interior. Also, at the extremity of arms there is a ball which is doing a rotation movement along the ring and it's own ax. The ball can be made of metal, or of an insulating material.

Description

ELECTROSTATIC MOTOR

Description of the invention:

Many types of electric motors are known, all of them having well -*- defined particularities. We refer here to the direct current motors, and to the alternative current motors. The direct current motors, from point of view of realizing the magnetic field and the stator, can be with permanent magnet, respectively with electromagnet. In the last case, field excitation can be classified as separately-excited, series-excited or shunt-excited. From the classification principle, the alternative current motor, are synchronous motors and asynchronous motors. All of them are driven through the interaction of the stator magnetic field with the rotor magnetic field. From this point of view, we name them magnetic motors. Each motor type presents its advantages and disadvantages.

Thus, the start up of direct current motors can be realized by using a variable starting resistor. Indifferent which motor type is being discussed, neither of them is realized with feed power from the source, smaller than 0,1W.

The electric motor commanded by the electric field removes the disadvantages of the motors we were referring to at the beginning of this paper as it follows: -its work principle is not based on magnetic field interaction, - no variable resistor is needed!

-it can be realized in alternatives, in which feed power from the source is minimum, with two orders | of size smaller than the minimum feed power with magnetic motors. There will be shown engines an example of our invention with a reference to the figure 1; which represents the scheme of construction of the motor driven through the electric field.

Fig. 1.

Under an insulating plate (3) (glass or a dielectric smooth composite) on the insulating stand (1) there is thin sheet of a conductor material (2). On the superior plate of glass there is a metal ring (5), (which touches the glass surface in three points (11) ). Between the metal ring and the aluminum thin sheet with a high-tension source (ST), it realizes an electric field. The tension of the source can be adjusted from 1,5 kN to 20 kN. In the interior of the ring there is the rotor. The number of the rotor's arms can be arbitrary from 1 to n; where n is the whole and positive number. The rotor is formatted by an immobile bearing (8), in which interior there is an axle (9), in which are fixed the rotor's arms (7). At the extremity of the arms is a counter-weight (6) (one counter-weight for one arm) realized by an insulating material and also there is a fork with (10) a ball (4) in its interior. Also, at the extremity of arms there is a ball which is doing a rotation movement along the ring and it's own ax. The ball can be made of metal, or of an insulating material. We start to feed the experimental device from a source of high continuous tension and we see that the rotor start a rotation movement with a constant speed. The rotor's speed can be regulated by the constructive elements (rotor's mass, the numbers of arms, the ring's ray, the ring's thickness) and the electric field's value; that is the feeding tension's value. The advantages of our motor consists of:

- it has a relatively simple constructs scheme,

- it can be used both with metallic balls and balls of dielectric material,

- it functions well.
