Stackable Magnetic Permeable Structure

Abstract

The invention relates to a stackable magnetic conductive structure which comprises a first insulating frame set, a first magnetic conductive element and a second magnetic conductive element, wherein the first insulating frame set comprises a first insulating frame and a second insulating frame. The first insulating frame and the second insulating frame are stacked with each other, so that two sets of magnetic conductive structures and even more sets of magnetic conductive structures can be combined so as to improve the size of the magnetic circuit cross section of a single magnetic conductive structure. A coil with a smaller wire radius is wound on the stackable magnetic conductive structure, so that the motor efficiency can be effectively increased.

Description

technical field [0001] The invention relates to a magnetically permeable structure, in particular to a stackable magnetically permeable structure. Background technique [0002] The existing known single-layer magnetic permeable structure includes a lower insulating frame, an upper insulating frame, and a silicon steel sheet between the lower insulating frame and the upper insulating frame. The single-layer magnetically permeable structure uses a coil to wind the lower insulating frame and the Put on the insulating frame and conduct current to generate magnetic force. Because of the wide cross-sectional area of ​​the magnetic circuit, a single magnetic conductive structure needs a thicker wire diameter to make it operate at the saturation point. Therefore, it is replaced by multiple sets of magnetic conductive structures to reduce the cross-sectional area of ​​the magnetic circuit. , so that it can reach the saturation point with a thinner wire diameter, so as to improve the ...

Problems solved by technology

[0003] When the coil is wound, it is easy to produce gaps between the enameled wires, and the larger the wire diameter of the coil used, the larger the gap, so the coil enameled wire with a thicker wire diameter has a poorer occupation rate and makes the skin effect more serious. As a result, the magnetic force generated by the coil is small and the copper loss increases. Relatively, when a coil with a thinner wire diameter is used to wind a single-layer magnetically permeable structure, although the enameled wire occupation rate can be increased, the coil with a thinner wire diameter has a larger Coil resistance, under the condition of the same rated voltage, the current passing through the coil decreases, resulting in a small magnetic force generated by the coil, but the resistance value of the coil is greatly reduced after multiple sets of magnetic permeable structures are connected in parallel, so that it can maintain the same magnetic force
