[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Embodiment 1 1 is a schematic diagram showing a stator structure 200 according to embodiment 1. The stator structure 200 has an annular shape. A straight line passing through the center of the stator structure 200 is defined as a central axis L.
[0012] A rotating body (not shown) that can rotate around a central axis L is inserted into a cylindrical space formed at the center of the stator structure 200. The stator structure 200 is used as a part of a resolver that can detect the rotational speed of the rotating body. Note that the stator structure 200 may also be used in devices other than resolvers.
[0013] The stator structure 200 includes a stator body 210, twelve coils 110, and a connecting member 1. The stator body 210 is composed of an annular yoke portion (not shown) and twelve teeth (not shown) that protrude radially inward from the yoke portion.
[0014] Each coil 110 is formed by winding a wire 110a around a corresponding tooth of the stator body 210. That is, the wire 110a wound around a tooth constitutes one coil 110. When viewed along the central axis L, the multiple coils 110 are arranged in a ring shape.
[0015] One end of the winding 110a forming the coil 110 extends away from the coil 110. One end of the winding 110a extending away from each coil 110 is defined as a coil wiring 111. That is, the coil 110 and the corresponding coil wiring 111 are electrically connected to each other.
[0016] Each of the coil wires 111 extends in the same direction along the central axis L. Each of the coil wires 111 is electrically connected to the connecting member 1.
[0017] Fig. 2 is a schematic diagram showing the connecting member 1 in Fig. 1. In Fig. 2, the visible surface of the circuit board 2 is the front surface, and the surface opposite to the front surface is the back surface. The connecting member 1 includes the circuit board 2 having an annular shape and 12 terminals 5 arranged on the outer periphery of the circuit board 2.
[0018] Each terminal 5 is arranged to protrude radially outward from the annular circuit board 2. Each terminal 5 is formed with a connection portion 5a, which is a space into which one coil wire 111 is inserted. The connection portion 5a is a U-shaped notch with an open tip. The notch opens radially outward from the circuit board 2.
[0019] When the coil wiring 111 is inserted into the connecting portion 5a, the coil wiring 111 is sandwiched between the terminals 5. In this state, the terminals 5 and the coil wiring 111 sandwiched between the terminals 5 are mechanically and electrically connected.
[0020] The width of the notch that is the connecting portion 5a may be constant in the depth direction, or the width of the notch may be narrowed in part in the depth direction.
[0021] Connection wiring 2a is provided by a printed wiring method on the front and back surfaces of the circuit board 2. The connection wiring 2a is provided so as to electrically connect two or more specific terminals 5 among the plurality of terminals 5.
[0022] In the present embodiment 1, four of the twelve terminals 5 are electrically connected to each other. That is, the connecting member 1 has three groups, each group consisting of four terminals 5 and the connecting wires 2a that electrically connect the terminals 5.
[0023] Two terminals 5 are present between terminals 5 that are included in the same group. The two terminals 5 that are present between terminals 5 that are included in the same group are included in different groups. The terminals 5 that are included in different groups are not electrically connected to each other.
[0024] One or more wiring through holes 2b are formed in the circuit board 2. The connection wiring 2a arranged on the front surface of the circuit board 2 and the corresponding connection wiring 2a arranged on the back surface of the circuit board 2 are connected to each other through the wiring through holes 2b. In Fig. 2, the connection wiring 2a provided on the back surface is indicated by dashed lines.
[0025] The connection wires 2 a disposed on either the front or back surface of the circuit board 2 can be electrically connected to a specific terminal 5 .
[0026] 2, the connection wiring 2a arranged on the outermost side of the circuit board 2 is arranged only on the surface of the circuit board 2. The connection wiring 2a arranged on the outermost side of the circuit board 2 is electrically connected to a corresponding specific terminal 5.
[0027] The connection wirings 2a arranged on the front surface of the circuit board 2, other than the outermost connection wirings 2a, are electrically connected via any of the wiring through holes 2b to the connection wirings 2a arranged on the back surface of the circuit board 2. The connection wirings 2a installed on the back surface of the circuit board 2 are electrically connected to corresponding specific terminals 5.
[0028] The connection wirings 2a other than the connection wirings 2a arranged on the outermost side of the circuit board 2 are electrically connected to the corresponding specific terminals 5 by using the connection wirings 2a provided on the back surface, without crossing the connection wirings 2a arranged on the outermost side of the circuit board 2. In other words, by using the front and back surfaces of the circuit board 2, the connection wirings 2a belonging to different groups can avoid electrical connection due to crossing.
[0029] The wiring path of the connection wiring 2a can be designed appropriately using the front and back surfaces of the circuit board 2.
[0030] Next, a description will be given of a method for manufacturing the stator structure 200. Fig. 3 is a flowchart showing a method for manufacturing the stator structure 200 according to the first embodiment.
[0031] <Wiring component preparation process> In step S01, a connecting member preparing step is carried out. The connecting member preparing step is a step of preparing the connecting member 1.
[0032] A plurality of terminals 5 are provided on the circuit board 2, and further, connection wiring 2a is provided to electrically connect each terminal 5 to the circuit board 2. At this time, the connection wiring 2a is formed based on a pre-designed pattern. In this way, the connection member 1 is prepared. This completes the connection member preparation process. The process then proceeds to the next step.
[0033] <Coil placement process> In step S02, a coil arrangement step is performed, in which the coil 110 is arranged on the stator body 210 that has been prepared in advance.
[0034] A winding 110a is wound around the teeth of the stator body 210 to form the coils 110. A coil 110 is formed for each of the teeth. When all the coils 110 are formed and arranged on the teeth, each coil 110 is arranged in a ring shape along the yoke portion.
[0035] At this time, the coils 110 are formed and arranged so that the coil wires 111 extending from each coil 110 extend in the same direction. That is, the coil wires 111 extend in the same direction along the central axis L.
[0036] This completes the coil arrangement process by forming the stator body 210. The process then proceeds to the next step.
[0037] <Wiring component connection process> Next, in step S03, a connecting member connecting step is performed. The connecting member connecting step is a step of connecting each of the coil wires 111 to the terminals 5 of the corresponding connecting members 1.
[0038] In the wire connection member connecting step, first, the wire connection member 1 is arranged so as to cover the end face perpendicular to the central axis L of the stator body 210. This end face is the end face from which each coil wire 111 extends. Next, the corresponding coil wire 111 extending from this end face is inserted into each of the connection portions 5a of each terminal 5.
[0039] Each coil wiring 111 inserted into the connecting portion 5a is sandwiched between the connecting portion 5a. The coil wiring 111 inserted into the connecting portion 5a is mechanically and electrically connected to the terminal 5. This completes the wire connection member connecting step, and the stator structure 200 is manufactured.
[0040] In addition, in the wiring member connecting process, in order to strengthen the electrical connection between the coil wiring 111 inserted into the connection portion 5a and the terminal 5, the terminal 5 may be deformed in a direction in which both the coil wiring 111 inserted into the connection portion 5a and the terminal 5 are crushed while the coil wiring 111 is inserted into the connection portion 5a and sandwiched therein.
[0041] In addition, with the coil wiring 111 inserted into the connection portion 5a and sandwiched therein, the coil wiring 111 inserted into the connection portion 5a and the terminal 5 may be fixed to each other by resistance welding. Furthermore, with the coil wiring 111 inserted into the connection portion 5a and sandwiched therein, the terminal 5 may be deformed in a direction in which both the coil wiring 111 inserted into the connection portion 5a and the terminal 5 are crushed, and then the coil wiring 111 inserted into the connection portion 5a and the terminal 5 may be fixed to each other by resistance welding.
[0042] When all the coil wires 111 are inserted into the connection portions 5a, the connecting member 1 is disposed so as to cover the end face of the stator body 210 without using any fastening means.
[0043] Note that well-known fastening means may be used to more firmly position the connecting member 1 on the end face of the stator body 210. Well-known fastening means include fastening with screws, fastening with snap members, and fastening with a caulking method.
[0044] The connecting member 1 according to the first embodiment includes a circuit board 2 having an annular shape or a portion of an annular shape, and a plurality of terminals 5 protruding radially outward from the outer periphery of the circuit board 2. The circuit board 2 is provided with connection wiring 2a that electrically connects the corresponding terminals 5. Each terminal 5 is formed with a connection portion 5a that can sandwich and electrically connect the coil wiring 111 connected to the corresponding coil 110. The coil wiring 111 is thus sandwiched between the connection portions 5a, thereby mechanically and electrically connecting the connecting member 1 and each coil wiring 111. This allows for solderless connection, thereby minimizing increases in the manufacturing cost of a stator structure 200 using the connecting member 1. Furthermore, the connection between each terminal 5 and the corresponding coil wiring 111 is achieved simply by sandwiching the coil wiring 111 between the connection portions 5a, thereby facilitating the connection between each terminal 5 and the corresponding coil wiring 111. This allows for reduced manufacturing costs of a stator structure 200 using the connecting member 1. This also allows the coil wiring 111 to be connected to the terminals 5 protruding outward from the outer periphery of the circuit board 2, preventing interference between the coil wiring 111 and the rotating body disposed in the space at the center of the stator structure 200. Therefore, by enlarging the space formed at the center of the connecting member 1 to some extent, a generalized connecting member 1 can be used for stator bodies 210 of various sizes, thereby reducing component costs.
[0045] In the connecting member 1 according to the first embodiment, each connection portion 5a is a notch formed in the terminal 5 and opening radially outward from the circuit board 2. This allows an operator to clamp the coil wiring 111 between the connection portions 5a from the outside of the stator structure 200. This makes it easy to connect each terminal 5 to the corresponding coil wiring 111. This allows the manufacturing cost of the stator structure 200 using the connecting member 1 to be reduced.
[0046] In the connecting member 1 according to the first embodiment, the connection wiring 2a is a printed wiring formed on the circuit board 2. This allows the connecting member 1 to be made thinner. Therefore, the stator structure 200 using the connecting member 1 can be made smaller in size.
[0047] The connecting member 1 according to the first embodiment has one terminal 5 for each corresponding coil 110. This makes it easier to find the corresponding terminal 5 when one coil wiring 111 is connected to the coil 110. Therefore, the coil wiring 111 can be connected to the terminal more accurately.
[0048] The stator structure 200 according to the first embodiment includes a connecting member 1 according to the present disclosure, a stator body 210, and a plurality of coils 110 mounted on the stator body 210. Coil wires 111 extend from each of the coils 110. Each of the terminals 5 of the connecting member 1 is connected to a corresponding one of the coil wires 111. This allows for solderless connection. This reduces the manufacturing cost of the stator structure 200. This facilitates connection between each of the terminals 5 and the corresponding coil wires 111, since the connection between each of the terminals 5 and the corresponding coil wires 111 is achieved simply by sandwiching the coil wires 111 between the connecting portions 5a. This reduces the manufacturing cost of the stator structure 200. This allows the coil wires 111 to be connected to the terminals 5 protruding outward from the outer periphery of the circuit board 2, preventing interference between the coil wires 111 and a rotating body disposed in the central space of the stator structure 200. Therefore, by increasing the space formed in the center of the connecting member 1 to a certain extent, it is possible to use a generalized connecting member 1 for stator bodies 210 of various sizes, thereby reducing component costs.
[0049] In the stator structure 200 according to the first embodiment, each coil 110 is formed by winding a wire 110a, and the coil wiring 111 is one end of the wire 110a. This allows the coil wiring 111, which is the end of the wire 110a that forms the coil 110, to be directly sandwiched between the connection portion 5a. This makes it easier to connect the coil 110 to the connecting member 1.
[0050] The connecting member connection method according to the first embodiment includes a connecting member preparation step of preparing the connecting member 1 of the present disclosure, a coil arrangement step of arranging a plurality of coils 110 in a ring shape, and a connecting member connection step performed after the coil arrangement step. The connecting member connection step also connects each coil wiring 111 connected to each coil 110 to the corresponding terminal 5 of the connecting member 1. Furthermore, in the wire connection process, the coil wiring 111 is sandwiched between the connection portions 5a of the terminals 5, thereby electrically connecting the coil wiring 111 to the terminals 5. This allows for solderless connection. This reduces the manufacturing cost of the stator structure 200 using the wire connection member 1. This also allows the coil wiring 111 to be connected to the terminals 5 protruding outward from the outer periphery of the circuit board 2, preventing interference between the rotating body disposed in the space at the center of the stator structure 200 and the coil wiring 111. Therefore, by enlarging the space formed at the center of the wire connection member 1 to a certain extent, a generalized wire connection member 1 can be used for stator bodies 210 of various sizes. This reduces component costs.
[0051] In the wire connection member connecting method according to the first embodiment, in a wire connection member connecting step, with each coil wiring 111 sandwiched and connected between the connection portions 5a of the corresponding terminals 5, the terminals 5 are deformed in a direction that crushes both the terminals 5 and the corresponding coil wiring 111. This results in a stronger connection between the terminals 5 and the corresponding coil wiring 111. This makes it possible to prevent the wire connection members 1 from falling off and to prevent poor connection between each coil wiring 111 and the wire connection members 1. This makes it possible to improve the reliability of the stator structure 200.
[0052] In the connecting member connecting method according to the first embodiment, in a connecting member connecting step, each coil wiring 111 is sandwiched between the connection portions 5a of the corresponding terminals 5, and then the coil wiring 111 and the terminals 5 are fixed to each other by resistance welding. This provides a stronger connection between the terminals 5 and the corresponding coil wiring 111. This prevents the connecting members 1 from falling off and prevents poor connection between each coil wiring 111 and the connecting members 1. This improves the reliability of the stator structure 200.
[0053] In the wire connection member connection method according to the first embodiment, in the coil arrangement step, each coil 110 is arranged so that the coil wirings 111 connected to each coil 110 face in the same direction. This makes it easier to connect the wire connection members 1 to each coil wiring 111. This makes it even easier to manufacture the stator structure 200.
[0054] Note that the connecting member 1 in the first embodiment has one terminal 5 for the corresponding coil 110. However, this is not limited thereto. Two terminals 5 may be provided for the corresponding coil 110. FIG. 4 is a schematic diagram showing a configuration in which two coil wires 111 protrude from one coil 110 in the stator structure 200 in FIG. 1. As shown in FIG. 4, two coil wires 111 protrude from one coil 110. The two coil wires 111 are both ends of the winding 110a that forms the coil 110. In this case, by providing the connecting member 1 with two terminals 5 for the corresponding coil 110, each coil wire 111 is connected to the corresponding terminal 5. Note that a connecting member 1 having two terminals 5 for one coil 110 may also be used for the stator structure 200 in which one coil wire 111 protrudes from one coil 110 as shown in FIG. 1.
[0055] The connecting member 1 according to the first embodiment has two terminals 5 for each corresponding coil 110. This allows the same connecting member 1 to be used whether one coil wire 111 or two coil wires 111 extend from the corresponding coil 110. Therefore, the connecting member 1 can be used for various stator bodies 210. This allows a more generalized connecting member 1 to be used for various stator structures 200, thereby reducing component costs.
[0056] Furthermore, the connecting member 1 in the first embodiment has an annular circuit board 2. However, this is not limited to this. Fig. 5 is a schematic diagram showing a configuration in which the circuit board 2 is cut out in the connecting member 1 in Fig. 2. For example, as shown in Fig. 5, the circuit board 2 may be annular and have a portion thereof cut out.
[0057] Furthermore, the coil 110 in the first embodiment is formed by winding a winding 110a. However, this is not limited thereto. For example, the coil 110 may be formed from block members. FIG. 6 is a schematic diagram illustrating the coil 110 in FIG. 1, in which the coil 110 is formed from block members 110c and 110d. The coil 110 shown in FIG. 6 includes a first block member 110c, a second block member 110d, and coil wiring 111 connected to a coil body 110b formed from the first block member 110c and the second block member 110d. The first block member 110c and the second block member 110d are each C-shaped. By butting the first block member 110c and the second block member 110d together, the coil body 110b having an opening 110e formed in the center can be obtained. Each coil 110 is arranged in the stator body 210 so that the teeth corresponding to the openings 110e are positioned. Although the coil body 110b is configured by two block members, a first block member 110c and a second block member 110d, the present invention is not limited to this. The coil body 110b, i.e., the coil 110, may be configured by one or more block members.
[0058] In the connecting member 1 according to the first embodiment, each coil 110 is configured of one or more block members, that is, a first block member 110c and a second block member 110d, and each coil 110 is connected to the corresponding coil wiring 111. This allows the stator structure 200 to use coils 110 that do not have windings 110a. This reduces the manufacturing cost of the coils 110.
[0059] Furthermore, the terminal 5 in the first embodiment is formed with a U-shaped connecting portion 5a with an open tip. However, this is not limited thereto. For example, the connecting portion 5a may be a through-hole formed in the center of the terminal 5. FIG. 7 is a schematic diagram showing an embodiment in which the connecting portion 5a of the terminal 5 in FIG. 2 is a through-hole. In this case, the coil wiring 111 is inserted into the connecting portion 5a, which is a through-hole, and is sandwiched and connected. Furthermore, the terminal 5 may be crushed and deformed in a direction narrowing the connecting portion 5a, which is a through-hole, to more firmly fix the coil wiring 111 to the terminal 5. Furthermore, the terminal 5 and the coil wiring 111 inserted into the connecting portion 5a, which is a through-hole, may be fixed to each other by resistance welding. Furthermore, the terminal 5 may be crushed and deformed in a direction narrowing the connecting portion 5a, which is a through-hole, and then the terminal 5 and the coil wiring 111 inserted into the connecting portion 5a, which is a through-hole, may be fixed to each other by resistance welding.
[0060] In the connecting member 1 according to the first embodiment, each connection portion 5a is a through hole formed in the terminal 5. This allows the terminal 5 and the connection portion 5a to be connected more reliably. This prevents the connecting member 1 from falling off and prevents poor connection between each coil wiring 111 and the connecting member 1. This improves the reliability of the stator structure 200.
[0061] Furthermore, the connection wiring 2a in the first embodiment is provided by a printed wiring method. However, this is not a limitation. The connection wiring 2a may be provided by a known wiring method or a known circuit formation method.
[0062] Furthermore, the connection wiring 2a in the first embodiment electrically connects the corresponding terminals 5 to each other. However, this is not limited to this. For example, one or more locations may be provided in a portion of the connection wiring 2a where the connection destination wiring can be selected. In other words, by appropriately selecting the connection destination wiring, it may be possible to select whether or not to connect the respective terminals 5 to each other. This allows a more generalized connection member 1 to be used for various stator structures 200, thereby reducing component costs. Various aspects of the present disclosure are summarized below as appendices.
