Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to an electromagnetic propulsion device that moves relative to a fluid using a coil.

(Prior Art) Conventionally, as a propulsion device for propelling a ship, for example,
For example, an internal combustion engine or a general electric motor is used to rotate a screw or to feed water backward by a pump or the like to obtain a propulsive force.

Further, in recent years, an electromagnetic propulsion device has been considered which generates a thrust by an electromagnetic force of a magnetic flux of an exciting coil in a superconducting state which is excited by a direct current and a direct current which is orthogonal to the magnetic flux and is applied to seawater.

(Problems to be solved by the invention) However, it is necessary to immerse the electrode pair in seawater in order to apply a direct current to the seawater, and to apply a DC voltage to the electrode pair, which causes a polarization effect in the electrode pair. , The hydrogen gas, the chlorine gas, etc. are generated from each of the electrode pairs in response to the applied current, and the electrode pairs themselves are corroded.

For this reason, the directions of the magnetic fluxes of the same phase are changed synchronously with the cycle of the AC voltage applied to the fixed electrode pair to prevent gas generation and corrosion of each electrode of the electrode pair. .

However, a characteristic AC excitation superconducting electromagnet is required, and the point of synchronization between the alternating current flowing in the liquid and the alternating magnet,
There is a problem that it is difficult to obtain a large-capacity propulsive force, such as a decrease in hydraulic power due to an increase in electricity and magnetic resistance due to an increase in the energization distance in the liquid between the magnetic poles.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an electromagnetic propulsion device capable of preventing gas generation and electrode corrosion and obtaining a large propulsion force.
