The winding structure can improve the sensitivity (slope), improve the output linearity, and enhance the winding efficiency.

[0004] The technical solution of the present invention is: a winding structure of a large-range linear displacement sensor, comprising a winding skeleton 1, an excitation winding 2, an output winding A3 and an output winding B4; a layer of the excitation winding 2 is evenly and densely wound in the winding space of the winding skeleton 1, and the winding space of the winding skeleton 1 is divided into two sections, one section is the output winding A3, and the other section is the output winding B4, the output winding A3 and the output winding B4 are on the surface of the excitation winding 2, wherein the output winding A3 and the output winding B4 are evenly segmented from the middle to the two ends, and the density of the number of winding turns on each section is controlled to increase by an equal amount.

[0005] The winding frame 1 is a hollow cylindrical structure with baffles at both ends to provide winding space.

[0006] The material used for the winding frame 1 is non-magnetic stainless steel.

[0007] The enameled wires used for the excitation winding 2, the output winding A3 and the output winding B4 are self-adhesive wires.

[0008] The winding spaces of the output winding A3 and the output winding B4 are divided into N sections of equal length, where N≥3.

[0009] Each winding section of the output winding A3 and the output winding B4 is evenly arranged, and the number of turns of each winding section increases exponentially.

[0010] The density of the number of turns of the output winding A3 and the output winding B4 increases by an equal amount from the center to the two ends, and the density change is set by programming the automatic winding machine.

[0011] The density of the number of turns of the output winding A3 and the output winding B4 increases equally from the center to the two ends, and this is achieved by controlling the density change of the windings using a semi-automatic winding machine using a multi-wire parallel winding method.

[0012] The beneficial effects of the present invention are as follows: the two output windings are evenly segmented from the center to the two ends, and the density of the winding turns on each segment is controlled to increase by an equal amount. When the mover core moves from the center to the two ends, the difference in the number of induced turns increases stepwise, thereby achieving the purpose of improving sensitivity (slope) and improving output linearity. In addition, the number of winding layers is reduced, the winding space requirement is reduced, the product volume and weight can be further compressed, the reliability is high, and it is more suitable for aviation equipment products.

[0017] The winding frame 1 is a hollow cylindrical structure with baffles at both ends to provide winding space.

[0018] The material used for the winding frame 1 is non-magnetic stainless steel.

[0020] The winding spaces of the output winding A3 and the output winding B4 are divided into N sections of equal length, where N≥3.

[0021] Each section of the output winding A3 and the output winding B4 is evenly arranged, and the number of turns of each section increases exponentially. The density of the number of turns of each section of the output winding A3 and the output winding B4 increases by an equal amount from the center to the two ends, which is achieved by programming the density change of the automatic winding machine.

[0022] The density of the number of turns of the output winding A3 and the output winding B4 increases from the center to the two ends in an equal amount, and the semi-automatic winding machine uses a multi-wire parallel winding method to control the change in the density of the winding.
