Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic circuit theories are limited by the inability to actively change the phase relationship between magnetic circuit vectors, restricting the control over the operating state and trajectory of magnetic circuits.
Innovation Solution
The introduction of a passive magnetic-inductance component, which is a multi-turn closed coil connected head to tail and wound around the magnetic circuit, allows for the control of both the magnitude and phase relationship of magnetic flux when the magnetomotive force (MMF) is constant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only reluctance components are used in magnetic circuits, then the structure is simple, but the phase relationship between magnetic flux and MMF cannot be controlled
Solution Approach 1:
The patent introduces an auxiliary magnetic circuit branch as an intermediary element. This branch contains a magnetic flux source and magnetic path, acting as a mediator that couples with the main magnetic circuit through shared magnetic paths. The intermediary branch enables phase relationship control without directly complicating the main circuit structure, as the phase control function is achieved through the coupling interaction between the auxiliary and main circuits.
Solution Approach 2:
The magnetic circuit is segmented into a main magnetic circuit and an auxiliary magnetic circuit branch. The auxiliary branch is separated as an independent segment containing its own magnetic flux source and path elements. This segmentation allows the phase control function to be isolated in the auxiliary segment, maintaining the simplicity of the main circuit while adding controllability through the separated auxiliary component.
2Adaptability or versatility
If traditional magnetic circuit components are used, then the component count is low, but the operating trajectory control of magnetic circuit vectors is limited
Solution Approach 1:
The auxiliary magnetic circuit branch serves multiple functions: it provides additional magnetic flux paths, enables phase relationship control, and allows operating trajectory adjustment of magnetic circuit vectors. By integrating this multi-functional auxiliary branch, the system achieves enhanced adaptability without proportionally increasing complexity, as a single auxiliary structure performs multiple control functions simultaneously.
Solution Approach 2:
The auxiliary magnetic circuit acts as a universal intermediary that can be coupled with different main circuit configurations. Through the shared magnetic paths and coupling mechanisms, this single auxiliary component can adapt to various operating conditions and control different vector trajectories, providing versatility without requiring multiple specialized components for each control function.

AI summary
A magnetic-inductance component is a multi-turn closed coil connected head to tail and wound around a magnetic circuit. A magnetic-inductance value of the magnetic-inductance component is adjusted by selecting metal conductors with different numbers of turns, materials, cross-sectional areas, and lengths to change an amplitude and phase of a magnetic flux of the magnetic circuit. The present invention changes the operating state and operating trajectory of a vector in the magnetic circuit by adding the magnetic-inductance component to the magnetic circuit or removing the magnetic-inductance component from the magnetic circuit, to make a state of a magnetic flux vector in the magnetic circuit to be consistent with a target magnetic flux vector state. A magnetic circuit vector model built by using the magnetic-inductance component as a core is more consistent with the actual physical situation, which is beneficial to the improvement of the accuracy of magnetic circuit analysis and calculation.
