1 is a view for explaining an electric motor using an electric field according to an embodiment of the present invention.

Referring to FIG. 1, an electric motor 100 includes a first stator 110, a second stator 120, and a rotor 130 and a shaft 140.

The first stator 110 may include a first conductor to which a first voltage V1 is applied. For example, the first conductor may include a base conductor including a first through hole through which the shaft 140 penetrates, and a protruding conductor protruding from the base conductor.

The second stator 120 may include a second conductor to which a second voltage V2 is applied. For example, the second conductor may be arranged to be rotated by a predetermined angle with the first conductor. For example, the second conductor may include a base conductor including a second through-hole through which the shaft 140 penetrates, and a protruding conductor protruding from the base conductor.

For example, the first stator 110 and the second stator 120 may be fixedly coupled to a case surrounding the first stator 110, the second stator 120, and the rotor 130, Such as by being fixed by means of various means.

The shapes of the first stator 110 and the second stator 120 will be described in detail with reference to Figs. 2 to 4. Fig.

The rotor 130 is positioned between the first stator 110 and the second stator 120 and can be coupled to the shaft 140. The rotor 130 may have a charge. For example, the rotor 130 may include shaft holes that can be engaged with the shaft 140. When the rotor 130 is rotated, the shaft 140 is rotated. At this time, the first stator 110 and the second stator 120 do not rotate.

The first stator 110, the second stator 120, and the rotor 130 may be in the form of plates such as a disk, a square, and the like, but are not limited thereto.

1, the first stator 110 and the second stator 120 may be alternately spaced apart from each other, and the rotor 130 may include a first stator 110 and a second stator 120, Respectively. As the number of the first stator 110, the second stator 120, and the rotor 130 increases, the output of the electric motor 100 can be improved.

Since the electric motor 100 is driven by using an electric field, a permanent magnet and a coil used for a motor using a magnetic field are not used. Therefore, the electric motor 100 can reduce the weight as compared with the motor using the magnetic field. Further, since the electric motor 100 does not use a permanent magnet, it can deviate from the dependence on a specific material (for example, a rare-earth substance) used for manufacturing the permanent magnet.

Also, the electric motor 100 can easily increase the output without increasing the voltage by increasing the number of the first stator 110, the second stator 120, and the rotor 130. Thus, the output of the electric motor 100 can be increased while the electric power consumed in the electric motor 100 is minimized.

A force 1310 acts on the charges included in the first rotor 130 by the electric field generated between the first stator 110 and the second stator 120. Accordingly, the rotor 130 can rotate in the direction of the force 1310. [

The third stator 160 may be coupled to the lower side of the second stator 120. For example, the third stator 160 may be coupled to the lower side of the second conductor 123.

The third stator 160 includes a fourth insulator 162 and a fourth conductor 163. The upper surface of the fourth insulator 162 may be an inclined surface. The lower surface of the fourth conductor 163 may be an inclined surface. The fourth conductor 163 may be coupled to the lower side of the second conductor 123. The inclined surface of the fourth insulator 162 and the fourth conductor 163 can be coupled to each other. And the second voltage V2 may be applied to the fourth conductor 163.

The fourth stator 170 includes a fourth insulator 172 and a fourth conductor 173. The fourth conductor 173 may be arranged to be rotated by a predetermined angle with the third conductor 163. The lower surface of the fourth insulator 172 may be an inclined surface. The fourth conductor 173 may have an inclined upper surface. The inclined surface of the fourth insulator 172 and the fourth conductor 173 can be coupled to each other. The first voltage V1 may be applied to the fourth conductor 173.

The second rotor 180 is disposed between the third stator 160 and the fourth stator 170 and may be coupled to the shaft 140. The second rotor 180 may have a charge opposite to that of the first rotor 130.

The direction of the electric field generated between the third stator 160 and the fourth stator 170 is opposite to the direction of the electric field generated between the first stator 110 and the second stator 120. Since the electric charge of the second rotor 180 is opposite to the electric charge of the first rotor 130, by the electric field generated between the third stator 160 and the fourth stator 170, (1320) acts on the charge contained in the charge storage layer (130). Accordingly, the rotor 130 can rotate in the direction of the force 1320. [

When the first rotor 130 and the second rotor 180 are rotated, the shaft 140 is rotated. At this time, the stators 110, 120, 160, and 170 do not rotate. Since the two rotors 130 and 180 rotate, the rotational force of the shaft 140 can be increased.

Comparing this embodiment with FIG. 12A, the present embodiment does not use the third insulator 150 when stacking a plurality of stators and rotors, thereby reducing the overall motor size.

9 and 13B, the first conductor 113, the second conductor 123, the third conductor 163, and the fourth conductor 173 may be arranged to be aligned with respect to the longitudinal axis. As such, the first conductor 113 and the second conductor 123 may be disposed coincident with each other along the longitudinal axis or rotated by a predetermined angle.

In this embodiment, the case where both the insulator and the conductor are included in the stator has been described, but the stator may include only the conductor, and the present embodiment can be applied to this case as well.

The first stator 110 may include a first conductor to which a first voltage V1 is applied.

The second stator 120 may include a second conductor to which a second voltage V2 is applied.

The rotor 130 is positioned between the first stator 110 and the second stator 120 and can be coupled to the shaft 140. The rotor 130 may have a charge. For example, the rotor 130 may include shaft holes that can be engaged with the shaft 140. When the rotor 130 is rotated, the shaft 140 is rotated. At this time, the first stator 110 and the second stator 120 do not rotate.

The first electric field enhancement portion 1400 may be disposed on the uppermost side of the disposed stators 110 and 120.
