Technical Information: Helmholtz Coil, Gap Variable Type

Technical Information: Helmholtz Coil, Gap Variable Type

Helmholtz coil with a coil spacing variable between 200 mm ± 20 mm.

We have manufactured a Helmholtz coil magnetic field generator that can vary the coil spacing from 200 mm ± 20 mm. After consulting with the customer about the generated magnetic flux density and usage, we designed, manufactured, and delivered the fixtures, jigs, and systems. Modifications can be made to the size, magnetic flux density, diameter of the opposing magnetic pole surfaces, and the coil winding specifications (wire diameter and number of turns). Using the base handle, it can rotate 360 degrees in any direction. We will design according to your requirements. For more details, please download the catalog or contact us.

High-density compressed molding coil

High-density compressed molding coil

Not only cars, but it can also be applied to various motors, leading to immediate efficiency improvements!

We handle "high-density compression molded coils," which are made by compressing round wire coils and packing as much wire as possible into a designated core. When used as an SR motor, it eliminates the need for magnets, resulting in a motor that is inexpensive, small, high-performing, and has excellent heat dissipation. 【Features】 ■ Round wire is cheaper than flat wire and can be compression molded without damaging the insulation. ■ It is possible to pack as much wire as possible into the gaps of the core (high packing density), achieving space-saving and high performance. ■ Because it is molded, we can provide uniform coils in various shapes, stabilizing the magnetic force. *For more details, please download the PDF or feel free to contact us.
