Embodiment Construction

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

[0023] The invention proposes a magnetic induction element, the core content of which is to purposely change the running state and track of the vector in the magnetic circuit by adding or reducing the magnetic induction element in the magnetic circuit. For example, when the magnetic potential in the magnetic circuit is stable, the magnitude of the magnetic flux in the magnetic circuit and the phase angle between the magnetic potential and the magnetic flux are changed by adding a magnetic induction element in the magnetic circuit, so that the state of the magnetic flux vector in the magnetic circuit is consistent with the The target flux vector state is consistent.

[0024] The magnetic induction element is physically represented as a multi-turn short-circuit coil wound on the magnetic circuit, and its symbol is L mc , the subscript...

Abstract

The invention provides a magnetic induction element, and relates to the field of magnetic circuit theories and application, in particular to design of a magnetic circuit element. The magnetic induction element is a multi-turn short-circuit coil wound on a magnetic circuit, 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 so as to change the amplitude and the phase of the magnetic flux of the magnetic circuit. According to the invention, by adding or reducing the magnetic induction elements in the magnetic circuit, the running state and track of the vector in the magnetic circuit are changed purposefully, so that the magnetic flux vector state in the magnetic circuit is consistent with the target magnetic flux vector state. Compared with a pure magnetic resistance magnetic circuit, the magnetic circuit vector model established by taking the magnetic induction element as the core is more consistent with the physical actual situation, and the magnetic circuit analysis and calculation precision is improved.

Description

technical field [0001] The invention relates to the field of magnetic circuit theory and application, in particular to the design of magnetic circuit elements. Background technique [0002] In the current textbooks and scientific research papers, the circuit contains various electrical components such as resistors, inductors, capacitors, and controlled sources. Researchers can control the trajectory of each vector in the circuit by adding or reducing circuit components in the circuit. and status. Compared with the electrical components in the circuit, the components of the magnetic circuit are relatively simple, including only two components: permanent magnet (magnetomotive force source) and reluctance. By adding or reducing the magnetic circuit elements, only the modulus of the magnetic circuit vector can be changed, it is difficult to change the phase of the magnetic circuit vector, and the characteristics of the magnetic circuit vector cannot be fully reflected. Therefo...
