[0048] See attached Figure 1-3 An angle sensor stator according to an embodiment of the present application is exemplarily described.

[0049] The angle sensor stator includes a transmitting coil 100, a first induction coil 200 and a second induction coil 300. The first transmitting coil 100 is connected to an oscillator, which can generate a periodic AC signal and couple the AC signal to the transmitting coil 100, thereby generating a magnetic field through the transmitting coil 100. It should be noted that the transmitting coil 100 in the present application can also be referred to as an excitation coil or an excitation coil. The first induction coil 200 and the second induction coil 300 are located in the magnetic field generated by the transmitting coil 100, and are connected to a signal analysis device, which can analyze the induction signal (such as a voltage signal) generated by the induction coil and then perform angle measurement. In an embodiment of the present application, the first induction coil 200 can be used to generate a sine signal (sin signal), and the second induction coil 300 can be used to generate a cosine signal (cos signal). The signal analysis device is configured to determine the angle of the target to be measured according to the phase difference between the induction signals generated by the first induction coil 200 and the second induction coil 300.

[0050] In the embodiment of the present application, the transmitting coil 100 includes a first coil body 110, a first lead wire 120, a second coil body 130, a second lead wire 140 and a first connecting wire 150. The first coil body 110 and the first lead wire 120 are located on a first plate body, the first coil body 110 includes a multi-turn coil, the first lead wire 120 is connected to the outside of the first coil body 110 (that is, the first coil body 110 is away from the center side), and the first lead wire 120 is used to connect the first coil body 110 and the oscillator. The second coil body 130 and the second lead wire 140 are located on a second plate body, the second plate body is parallel to the first plate body, the second coil body 130 includes a multi-turn coil, the second lead wire 140 is connected to the outside of the second coil body 130 (that is, the second coil body 130 is away from the center side), and the second lead wire 140 is used to connect the second coil body 130 and the oscillator. The first coil body 110 and the second coil body 130 are connected by a first connecting wire 150, and the first connecting wire 150 is located between the first plate body and the second plate body. Specifically, the first plate body and the second plate body are both PCB (printed circuit board) plates, the first coil body 110 and the first lead wire 120 can be arranged on the first PCB, the second coil body 130 and the second lead wire 140 can be arranged on the second PCB, the first PCB is parallel to the second PCB, and a via is arranged on the first PCB, and the first coil body 110 is connected to the first connecting wire 150 through the via. The first connecting wire 150 is perpendicular to the first plate body and the second plate body, so that the alternating current passing through the first connecting wire 150 can be prevented from interfering with the first coil body 110 and the second coil body 130, and the sinusoidality of the alternating current inside the transmitting coil 100 can be prevented from being reduced.

[0051] In the embodiment of the present application, the first coil body 110 and the second coil body 130 are in annular shape and are coaxially arranged, that is, the projection of the center (center of the circle) of the first coil body 110 on the second plate body coincides with the center of the second coil body 130, and the projection of the first coil body 110 on the second plate body at least partially coincides with the second coil body 130. By configuring the first coil body 110 and the second coil body 130 to overlap in space, the parasitic capacitance generated between the first coil body 110 and the second coil body 130 can be effectively reduced to avoid unnecessary resonance from interfering with the signal.

[0052] See attached Figure 1 , 2 In the embodiment of the present application, the projection of the first lead 120 on the second board at least partially overlaps with the second lead 140, so that the first lead 120 and the second lead 140 overlap in space, which can effectively reduce parasitic (stray) capacitance and parasitic (stray) inductance, reduce the generation of harmonics, and ensure the integrity of the waveform. Figure 2 In the embodiment of the present application, the first lead wire 120 includes a first lead section 121, a first overlapping section 122, and a second lead section 123. The first end of the first lead section 121 is connected to the first coil body 110, the second end of the first lead section 121 is connected to the first end of the first overlapping section 122, and the second end of the first overlapping section 122 is connected to the first end of the second lead section 123. The second lead wire 140 includes a third lead section 141, a second overlapping section 142, and a fourth lead section 143. The first end of the third lead section 141 is connected to the second coil body 130, the second end of the third lead section 141 is connected to the first end of the second overlapping section 142, and the second end of the second overlapping section 142 is connected to the first end of the fourth lead section 143. The projection of the first overlapping section 122 on the second plate overlaps with the second overlapping section 142.

[0053] See attached Figure 2 In the embodiment of the present application, the first overlapping segment 122 and the second overlapping segment 142 are both straight lines, and the extension line of the first overlapping segment 122 and the extension line of the second overlapping segment 142 pass through the center of the first coil body 110 and the center of the second coil body 130 respectively, that is, the first overlapping segment 122 and the second overlapping segment 142 pass through the first coil body 110 vertically, thereby effectively reducing the interference between the first overlapping segment 122 and the second overlapping segment 142 and the first coil body 110 and the second coil body 130.

[0054] See attached Figure 2 , 3 In the embodiment of the present application, the projection of the first lead section 121 on the second plate is perpendicular to the third lead section 141, and the projection of the second lead section 123 on the second plate is perpendicular to the fourth lead section 143. Thus, when a high-frequency AC signal passes through the first lead section 121 and the third lead section 141, according to the right-hand screw rule, the magnetic fields generated by the first lead section 121 and the third lead section 141 will cancel each other, and will not generate interference in other directions, which can effectively avoid the interference of the lead line to the outside, thereby effectively reducing the generation of harmonics in the output signal of the induction coil. Similarly, when a high-frequency AC signal passes through the second lead section 123 and the fourth lead section 143, the magnetic fields generated by the second lead section 123 and the fourth lead section 143 will cancel each other, and will not generate interference in other directions.

[0055] See attached Figure 2 , 3In the embodiment of the present application, the first coil body 110 and the second coil body 130 each include 3 turns of coil (in some other embodiments, it may be 2 turns, 4 turns or more turns), and two adjacent turns of coil in the first coil body 110 are connected by connecting section 111 and connecting section 112 respectively, and connecting section 111 is parallel to connecting section 112, and two adjacent turns of coil in the second coil body 130 are connected by connecting section 131 and connecting section 132 respectively, and connecting section 131 is parallel to connecting section 132. The projection of connecting section 111 on the second plate body is staggered with connecting section 131, and the angle between the two is 60° (calculated as an acute angle, the obtuse angle formed between the two is 120° accordingly), and similarly, the projection of connecting section 112 on the second plate body is staggered with connecting section 132, and the angle between the two is 60° (calculated as an acute angle, the obtuse angle formed between the two is 120° accordingly). The induced voltages generated by the angles formed by the spatially staggered routing of the connecting segments between adjacent turns of the first coil body 110 and the second coil body 130 are superimposed and cancel each other out, so as to reduce the harmonic problem caused by the routing. In some other embodiments, the angle between the projection of the connecting segment 111 on the second plate and the connecting segment 131 (that is, the angle between the projection of the connecting segment 112 on the second plate and the connecting segment 132) can be 90° or other angles between 60° and 90°, and those skilled in the art can configure it as needed.

[0056] See attached Figure 3 In the embodiment of the present application, the innermost turn of the coil in the first coil body 110 is connected to the first end of the first connecting line 150 through the connecting section 113, and the innermost turn of the coil in the second coil body 130 is connected to the second end of the first connecting line 150 through the connecting section 133. The projection of the connecting section 113 on the second plate is perpendicular to the connecting section 133. Therefore, when the high-frequency AC signal passes through the connecting section 113 and the connecting section 133, the magnetic fields generated by the connecting section 113 and the connecting section 133 will cancel each other out, and no interference in other directions will be generated.

[0057] See attached Figure 2In the embodiment of the present application, the first induction coil 200 includes a first coil part 210, a third lead wire 220, a second coil part 230, a fourth lead wire 240 and a second connecting wire (not shown in the figure).

The first coil part 210 includes a plurality of arc wires, the third lead wire 220 is connected to the first coil part 210, and the first lead wire 120 is used to connect the first coil part 210 and the signal analysis device. The second coil part 230 and the fourth lead wire 240 are located on the fourth plate body, the fourth plate body is parallel to the third plate body, and the third plate body and the fourth plate body are located between the first plate body and the second plate body. The second coil part 230 includes a plurality of arc coils, the second lead wire 140 is connected to the second coil part 230, and the second lead wire 140 is used to connect the second coil body 130 and the signal analysis device. The first coil portion 210 and the second coil portion 230 are connected by a plurality of second connecting wires, and the second connecting wires are located between the third plate and the fourth plate. The projection of the first coil portion 210 on the fourth plate forms a spiral continuous line with the fourth coil portion, and the projection of the first coil portion 210 and the second coil portion 230 on the second plate is located inside the second coil body 130 and surrounds the center of the second coil body 130. In the embodiment of the present application, the outer diameter (the diameter of the outermost coil turn) of the first coil body 110 and the second coil body 130 is 28mm, and the inner diameter (the diameter of the innermost coil turn) is 25mm. The outer circle diameter (the diameter of the circle passing through its outer edge) of the projection of the first coil portion 210 and the second coil portion 230 on the second plate is 24mm, and the inner circle diameter (the diameter of the circle passing through its inner edge) is 10mm. Specifically, the third board and the fourth board are both boards of PCB (printed circuit board), the first coil part 210 and the third lead 220 can be arranged on the third PCB, the second coil part 230 and the fourth lead 240 can be arranged on the fourth PCB, the third PCB is parallel to the fourth PCB, and the third PCB is parallel to the first PCB, the third PCB and the fourth PCB are both located between the first PCB and the second PCB, that is, the first PCB, the second PCB, the third PCB and the fourth PCB are parallel to each other, the first PCB and the second PCB are located at the top layer and the bottom layer (that is, the first layer and the fourth layer from top to bottom), and the third PCB and the fourth PCB are located at the second layer and the third layer from top to bottom. The third PCB is provided with a via, and the first coil part 210 is connected to the second connecting line through the via. The second connecting line is perpendicular to the third board and the fourth board, so that the induction current passing through the second connecting line can be prevented from interfering with the first coil part 210 and the second coil part 230.

[0058] In the embodiment of the present application, the projection of the third lead wire 220 on the fourth plate at least partially overlaps with the fourth lead wire 240, so that the third lead wire 220 and the fourth lead wire 240 overlap in space, which can effectively reduce parasitic (stray) capacitance and parasitic (stray) inductance, reduce the generation of harmonics, and ensure the integrity of the waveform. Figure 2 In the embodiment of the present application, the third lead-out line 220 includes a third overlapping section 221 and a fifth lead-out section 222, the first end of the third overlapping section 221 is connected to the first coil portion 210, and the second end of the third overlapping section 221 is connected to the first end of the fifth lead-out section 222.

The projection of the third overlapping section 221 on the fourth plate overlaps with the fourth overlapping section 241.

[0059] See attached Figure 2 In the embodiment of the present application, the projection of the fifth lead-out section 222 on the fourth plate is perpendicular to the sixth lead-out section 242. Therefore, when the AC signal passes through the fifth lead-out section 222 and the sixth lead-out section 242, according to the right-hand screw rule, the magnetic fields generated by the fifth lead-out section 222 and the sixth lead-out section 242 will cancel each other out, and will not generate interference in other directions, which can effectively avoid the interference of the lead-out line to the outside, thereby effectively reducing the generation of harmonics in the output signal of the induction coil.

[0060] In the embodiment of the present application, the third overlapping segment 221 is perpendicular to the first coil portion 210 connected to the third overlapping segment 221, and the fourth overlapping segment 241 is perpendicular to the second coil portion 230 connected to the fourth overlapping segment 241. That is, the third overlapping segment 221 is perpendicular to the tangent of the first coil portion 210 (the tangent at the intersection of the first coil portion 210 and the third overlapping segment 221) at the connection with the first coil portion 210, and the fourth overlapping segment 241 is perpendicular to the tangent of the second coil portion 230 (the tangent at the intersection of the second coil portion 240 and the fourth overlapping segment 241) at the connection with the second coil portion 230. In this way, the interference between the coil portion and the overlapping segment can be effectively reduced.

[0061] In the embodiment of the present application, the projections of the third overlapping section 221 and the fourth overlapping section 241 on the second plate are staggered with the second coil body 130 and are perpendicular to the second coil body 130, that is, the projections thereof are perpendicular to the tangent of the second coil body 130 at the connection with the second coil body 130 (that is, the extension line of the projections thereof passes through the center of the second coil body 130). In this way, the interference of the first coil body 110 and the second coil body 130 on the third overlapping section 221 and the fourth overlapping section 241 can be effectively reduced, and the generation of harmonics of the output signal can be reduced.
