Abstract

PURPOSE:To provide a displacement device capable of controlling the displacement amount and direction wide range using a solenoid coil. CONSTITUTION:In this displacement device, Lorentz's force is produced by feeding a current through a wire 4i orthogonal to a magnetic field (magnetic flux density vector B) offered between the end faces 3i, 2j of conductive cores 1a (hollow allowable) by feeding a current to a solenoid coil 4a made of the conductor cores 1a in respective parts formed of the notched isometrical gaps in the radial directions arranged in circular or regular polygonal shape so that the wire 4i may be pivotally displaced centered on a magnetic flux central axis on the surfaces orthogonal to the magnetic flux central axis of respective gaps. On the other hand, omnidirectional forces can be obtained by changing the rotation angle and turned into thrust from plural position on the solenoid coil 4a. At this time, the thrust thus obtained is to be controlled by adjusting the current to be fed to the wire 4i orthogonal to the magnetic field (magnetic flux vector B) offered between the end faces 3i, 2j.

A means for solving the problems will be described with reference to the drawings. First, the principle will be described. A wire is wound around the magnetic conductor core 1 as shown in FIG. 1, and a current I _{O is} passed through the wound wire 4. Of course, the conductor core 1 and the winding wire 4 are insulated (the same applies hereafter). A magnetic field H is generated (Biot-Savart's law) by causing the current I _O to flow through the winding 1, and a magnetic flux density vector B is obtained. The magnetic flux density vector B changes depending on the field flowing with respect to the generated magnetic field H. Vacuum: B = μ _O H conductors intracardiac: B = μH μ _O: space permeability ^{(4π × 10 -7 N / A} 2) N: number of turns of the coil A: (Fill) mu: conductor Toru Magnetic susceptibility (see Table 1)

When the magnetic flux density vector B exists in the conductor core 1 and between the end faces (2, 3) of the conductor core 1 as described above, the conductor core end faces (2, 3) as shown in FIGS. 2 and 3. _A Lorentz force F is obtained by passing a current I _A through the electric wire 5 that is orthogonal to the magnetic flux density vector B generated between them. Lorentz force: F = L · I × B (I and B perform vector product with vector) L: Length of electric wire that carries current I _A affected by magnetic field (magnetic flux density vector)

In order to efficiently obtain the Lorentz force thus obtained, the end faces 2, 3 of the conductor core 1 as shown in FIG.
By decreasing the gap S between them, the magnetic field H increases and the magnetic flux density vector B also increases. This is
The resulting force will increase.

This is because not only in the arc shape but also in the rod shape, by connecting the magnetic circuits and passing a current through a line orthogonal to the magnetic field (magnetic flux density vector) generated between the end faces of the connection points, the force is increased. can get. However, the arc-shaped solenoid coil is more efficient than the rod-shaped in order to obtain a force.

In order to effectively use the generated Lorentz force, it is desirable to reduce the weight, so it is preferable to make the hollow part of the way.
