Modular Magnetic Coupling Layout for Coreless Energy Transfer

The magnetic coupling device is divided into multiple independent coil modules arranged along a closed curved line. Each coil can be accessed and maintained individually without dismantling the entire assembly, as they are distributed with spacing rather than densely packed. This segmentation resolves the contradiction by maintaining magnetic coupling effectiveness through proper geometric arrangement while enabling easy individual access for maintenance.

The coils are arranged along a closed curved line (circular or elliptical geometry) rather than a straight line. This curvature allows coils to be spaced apart for maintenance access while the closed-loop geometry ensures that magnetic field lines remain confined and effective coupling is maintained between adjacent coils. The curved arrangement optimizes both maintenance accessibility and magnetic coupling strength simultaneously.

The magnetic core is extracted/removed from the traditional transformer structure, eliminating the complexity associated with magnetic core materials, saturation issues, and core losses. The invention achieves effective magnetic coupling without a core by relying on the geometric arrangement of coils along a closed curved line, which provides sufficient magnetic coupling for the application while simplifying the device structure.

The closed curved line arrangement (circular or elliptical) of coils provides natural magnetic field confinement within the loop geometry. The curved configuration guides magnetic field lines along the closed path, minimizing leakage outside the structure. While the geometry is curved, the manufacturing complexity is managed by using standard coil winding techniques on a curved form, making the solution practical despite the non-linear arrangement.
