Problems solved by technology

[0002] The 8-shaped coil is a special coil structure. This coil will form a magnetic field peak in the middle of the two circular coils. The magnetic field at this position has high strength and long operating distance, so it is widely used in medical treatment. And in the industry, but because the main role of this 8-shaped coil is in the middle of the two coils, the middle of the coil needs to contain as many turns of cables as possible. The stacking of the coils will cause the overall size of the middle to be too large, and the middle stack The cable will also cause a gap between the two adjacent cables in the coils on both sides. The generation of this gap will reduce the overall magnetic field strength of the coil and cause a large current loss; there are also a few designs that use vortex wires. The 8-shaped coil replaces the 8-shaped coil, but the vortex-shaped coil will cause the radial dimension between the two coils to be too large. When the radial dimension becomes larger, the active area of ​​the magnetic field in the middle will increase, and the strength of the magnetic field will be reduced at the same time.
And the vortex-shaped coil will have a certain difference from the 8-shaped coil in the shape of the magnetic field range, and it cannot completely replace the 8-shaped coil

Abstract

The invention discloses a magnetic field generating coil, which comprises: a first coil, a second coil, and a middle wire; the first coil, the second coil, and the middle wire are wound by cables; The first middle cable and the second middle cable, the first ring cable part arranged in the first coil, and the second ring cable part arranged in the second coil; the first middle cable and the second middle cable overlap each other , and the first middle cable is located at the uppermost end of the middle conductor, and the second middle cable is located at the lowermost end of the middle conductor. Also provided is a winding method of the magnetic field generating coil. The structure of this design can reduce the axial size of the coil, and the positions of the middle wires stacked with each other will form a moderately sized middle wire area, the width of this area will not change with the design turns of the coil, and the axial thickness will be Keep the same with the coils on both sides for easy control of the overall volume of the coil.

Description

A kind of magnetic field generating coil and winding method of coil technical field [0001] The invention belongs to the technical field of electromagnetic coils, and in particular relates to a magnetic field generating coil and a winding method of the coil. Background technique [0002] The figure-8 coil is a relatively special coil structure, and this coil will form a A magnetic field peak, the magnetic field at this position has a high strength and a long acting distance, so it is widely used in medical In medicine and industry, but the main action position of this figure-8 coil is in the middle of the two coils, so the middle of the coil needs to be wrapped. For cables with as many turns as possible, the stacking of coils will cause the overall size of the middle to be too large, and the stacked cables in the middle will also be too large. It will cause a gap between the two adjacent cables in the coils on both sides, which will reduce the overall magnetic field of ...
