Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] The present invention proposes a magnetic sensor element, and its core content is to change the vector operation status and trajectory of the magnetic circuit in a manner in which the magnetic transmission is increased or reduced in the magnetic circuit. For example, when the magnetic transmission is stable in the magnetic circuit, the magnetic flux size and the phase angle of the magnetic path and the magnetic flux are changed by increasing the magnetic circuit in the magnetic circuit, so that the magnetic flux vector state in the magnetic circuit is made The target flux vector is consistent.

[0024] The magnetic sensor represents a closed coil that is wrapped around the multi-turns of the magnetic circuit in the physical form, and its symbol is L mc The meaning of the subscript is the abbreviation of English word MagneTic Circui...

Abstract

The invention provides a magnetic induction element, which relates to the field of magnetic circuit theory and application, in particular to the design of the magnetic circuit element. The magnetic induction element is a closed coil wound on the magnetic circuit with multiple turns connected head to tail, and the magnetic induction value of the magnetic induction element is adjusted by selecting metal conductors with different turns, materials, cross-sectional areas, and lengths to change The magnitude and phase of the magnetic flux in the magnetic circuit. The present invention purposefully changes the operating state and track of the vector in the magnetic circuit by adding or reducing the magnetic induction element in the magnetic circuit, so that the state of the magnetic flux vector in the magnetic circuit is consistent with the state of the target magnetic flux vector; Pure reluctance magnetic circuit, the magnetic circuit vector model established with the magnetic induction element as the core is more consistent with the actual physical situation, which is beneficial to improve the accuracy of magnetic circuit analysis and calculation.

Description

Technical field [0001] The present invention relates to magnetic circuit theory and application, in particular, to the design of magnetic circuit components. Background technique [0002] In the current teaching materials and research papers, there is a variety of electrical components such as resistance, inductance, capacitance, and controlled source, and researchers can control the operation trajectory of each vector in the circuit by increasing or decreasing circuit components in the circuit. And status. Compared with the electrical components in the circuit, the components of the magnetic circuit are simpler, and only the two components of the permanent magnet (magnetic source) and magnetoresistance. By increasing or reducing the modulus of the magnetic circuit vector, it is difficult to change the phase of the magnetic circuit vector, and the characteristics of the magnetic circuit vector cannot be fully reflected. Therefore, how to supplement with the magnetic circuit compo...
