  However, the inventors have examined further improvements with respect to the above-described prior art. For example, when a rotating electrical machine is used in a vehicle or the like, it is often driven relatively continuously, and the wire and the stator core arranged in the rotating electrical machine (particularly the stator of the rotating electrical machine) generate heat by this continuous drive. Therefore, it is a problem to maintain the performance of the rotating electrical machine due to this influence. In the technique of Patent Document 1, since the plurality of laminated wire rods 70 have the turn portions 74 (including the crank portion 76) overlapped in the lamination direction, it is difficult to release the heat generated in the wire rods 70 and the like.

  The present invention has been made in view of the above points, and provides a stator for a rotating electrical machine and a rotating electrical machine that can easily release heat generated by a wire and the like and can appropriately maintain the performance of the stator of the rotating electrical machine. The purpose is to provide.

In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that a stator core (also referred to as “stator core”) having a plurality of slots in the circumferential direction, and a conductive material disposed in the slots. In the stator of a rotating electrical machine having a wire rod, the wire rod includes an in-slot housing portion housed in a slot of the stator core, and another slot spaced from the in-slot housing portion and the slot by a predetermined pitch. And a turn part formed to protrude from an end face of the stator core, and the turn part is in the width direction of the wire and fixed. convex partially bent in the protruding direction to protrude from the end face of the child core and the end face of the stator core is accommodated in said different slots and a portion to be bent concavely in the width direction opposite the turn portions Characterized in that it has a convex portion which is formed is recessed in said projecting direction than the other middle portion of the turn portion through.

According to this configuration, the convex part of the turn part has a concave part (inner part) that is recessed from the intermediate part of the other turn part (more specifically, the end surface in the protruding direction), so the generated heat is concave. It becomes easy to escape through the gap generated in the part. In other words, the gap becomes a path for the wind. Therefore, the performance of the stator can be suitably maintained. The “rotating electric machine” corresponds to, for example, an electric motor (motor), a generator, a generator motor, and the like.

  The invention according to claim 2 is characterized in that the convex portion is formed in an arc shape. According to this configuration, the convex portion can be formed only by partially bending the turn portion into an arc shape. Therefore, the invention can be simply configured with a low cost.

  The invention described in claim 3 is characterized in that the convex portion is provided at a substantially central portion of the turn portion. According to this configuration, the turn portion is substantially symmetric with respect to the convex portion, so that it can be easily accommodated in the slot of the stator core. Accordingly, workability in the stator manufacturing process can be improved.

  The invention described in claim 4 is characterized in that the turn portion is formed in a substantially linear shape within a predetermined width except for the convex portion. According to this configuration, characteristics equivalent to those formed in a straight line can be obtained within a predetermined width. In addition, since the length of the entire wire can be reduced by reducing the portion protruding from the end face of the stator core by forming it in a substantially linear shape, the electric resistance can be reduced and the performance of the rotating electrical machine can be improved.

  The invention according to claim 5 is characterized in that the turn part is formed so as to extend at a predetermined angle with respect to an end surface of the stator core from a boundary part with the slot accommodating part. According to this configuration, a gap can be secured between the turn portion and the end face of the stator core as the distance from the slot storage portion increases. Since this gap is secured also in the laminating direction in which a plurality of wires are laminated, it releases heat and also serves as a wind path. Therefore, the heat generated by the wire or the like can be easily released more reliably, and the performance of the rotating electrical machine can be more easily maintained.

  The invention according to claim 6 is characterized in that the in-slot housing portion is formed so as to protrude a predetermined distance from an end face of the stator core. According to this configuration, since the slot accommodating portion protrudes by a predetermined distance, the entire turn portion has a gap corresponding to the predetermined distance. This gap not only releases heat but also serves as a path for the wind. Therefore, the heat generated by the wire or the like can be easily released more reliably, and the performance of the rotating electrical machine can be more easily maintained.

In the seventh aspect of the invention , a plurality of the wire rods are radially stacked in the slot, and the turn portions of the wire rods housed in the same slot protrude from the end face of the stator core. Are the same, and the convex portions of the turn portions of the wire rods housed in different slots are shifted in the circumferential direction, and at least one of the convex portions of the stacked wire rods is in the radial direction. It is characterized in that a gap is formed toward the front. According to this configuration, since air flows through a gap generated at least at one place, the stator can be reliably cooled, and the performance of the rotating electrical machine can be maintained.

  The invention described in claim 8 is characterized in that the wire is formed of one continuous plate for each of the U phase, the V phase, and the W phase. According to this configuration, since the wire is formed of a single continuous plate, there is no connection portion, so an increase in resistance due to the connection can be prevented, and suitable performance of the rotating electrical machine can be maintained. In addition, the number of parts can be reduced.

  The invention according to claim 9 is characterized in that the wire is made of a coated copper body or a coated aluminum material. According to this configuration, even if any of the coated copper body and the coated aluminum material is used as the wire material, an equivalent electric resistance can be obtained. In addition, since the wire itself is soft, the assembling property of the wire into the slot is greatly improved.

  A tenth aspect of the present invention is a rotating electrical machine, and includes the stator according to any one of the first to ninth aspects. According to this configuration, the heat generated by the wire constituting the stator can be easily released, so that the performance of the entire rotating electrical machine can be suitably maintained.

It is a figure which shows typically the structural example of the whole wire. It is a side view which shows the external appearance of the wire arrange | positioned in the slot of a stator. It is a side view which shows an example of the clearance gap which arises with the shape of a wire. It is sectional drawing which shows the structural example of a rotary electric machine. It is a figure which shows the other shape of a convex-shaped part.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. When referring to the direction, the description in each figure is used as a reference. For example, “radial direction” means a radial direction passing through the center of a stator core formed in a cylindrical shape, and “circumferential direction” means a direction along the inner periphery or outer periphery of the stator core formed in a cylindrical shape. The “projecting direction” means a direction projecting from an end face of a stator core formed in a cylindrical shape (see FIG. 1).

  First, FIG. 1 schematically shows a configuration example of a stator in a perspective view. A stator 10 shown in FIG. 1 has a stator core 11 and a wire 12. The stator core 11 formed in a cylindrical shape is formed with a plurality of slots 13 (slots 13a, 13b, 13c, 13d, 13e, 13f, 13g, 13h,...) In the circumferential direction shown. . In each slot, the wire 12 is disposed (wrapped) so as to be laminated in the radial direction. Hereinafter, the direction in which the wires 12 are laminated is referred to as “lamination direction”. The wire 12 is made of a conductive material that is soft and easy to wind, such as a coated copper body or a coated aluminum material.

  After the wire 12 is thus placed in the slot 13, the wire 12 partially protrudes outside the slot 13 (in other words, from the end face 11a of the stator core 11) as shown in the drawing. The wire 12 is formed of one continuous plate for each phase. In FIG. 1, for three phases (U phase, V phase, W phase), a U phase wire 12U for U phase, a V phase wire 12V for V phase, and a W phase wire 12W for W phase are used. An example of arrangement is shown.

  A part of the configuration example of one wire 12 is shown in FIG. The wire 12 shown in FIG. 2 (A) is composed of an in-slot housing portion 12c and a turn portion 12b, and is formed from a single plate so that this is repeated. The in-slot housing portion 12c is a portion that is housed in the slot 13, and the turn portion 12b is a portion that projects outside the slot 13a.

  The in-slot housing portion 12d is a portion that is housed in the slot 13 like the in-slot housing portion 12c. However, since the position of the housing slot 13 is different, different symbols are assigned for convenience of explanation. The in-slot storage portion 12c and the in-slot storage portion 12d are stored in the slots 13 that are separated by a predetermined pitch. In the arrangement example of FIG. 1, for example, for the U-phase wire 12U, the in-slot housing portion 12c is housed in the slot 13a, and the in-slot housing portion 12d is housed in the slot 13g. The slot 13a and the slot 13g are separated by 6 pitches.

  Returning to FIG. 2A, the configuration of the turn portion 12b will be described. The turn part 12b is formed so as to extend with a predetermined angle θ with respect to the end face 11a of the stator core 11 from a boundary part with the slot accommodating part 12c. For example, the predetermined angle θ is set to 5 degrees to 60 degrees. Since the predetermined angle θ affects the height H of the turn part 12b, it is necessary to set the predetermined angle θ small when it is desired to reduce the height H. The in-slot housing portion 12c protrudes from the end surface 11a by a predetermined distance L to the boundary portion with the turn portion 12b.

Also, Ru includes a convex portion 12a is a part of the turn portion 12b (substantially central portion). An intermediate portion which is a part of the turn portion 12b and where the wire 12 continues between the convex portion 12a and the in-slot housing portion 12c is formed in a substantially linear shape. As shown in FIGS. 1 and 4, the intermediate portion is also a skew portion that proceeds obliquely when viewed from the end surface 11 a of the stator core 11. The convex portion 12a of the turn portion 12b (for example, the U-phase wire 12U shown in FIG. 1) is partially bent convexly in the protruding direction in the width direction of the wire 12, and has a concave shape on the opposite side in the width direction. The bent concave portion K is accommodated in a different slot 13 and is recessed in the protruding direction from the intermediate portion of another turn portion 12b (for example, the V-phase wire 12V shown in FIG. 1) passing through the end face 11a side of the stator core 11 . (See also FIG. 5 (A)) .
As shown in FIG. 2B, an intermediate portion 12e, which is a part of the turn portion 12b and where the wire 12 continues between the convex portion 12a and the slot accommodating portion 12c , is substantially within a predetermined width W. It is formed in a straight line. As long as it is within the range of the predetermined width W, it is not limited to a straight line and may be formed by a curve. The intermediate part 12e is also the above-described skew part. In the example of FIG. 2 (B), it is recessed in the direction opposite to the protruding direction (upward in the drawing) (downward in the drawing). The size (length) of the predetermined width W can be arbitrarily set, but is preferably, for example, 1 to 5 times the plate width of the wire 12.

  FIG. 3 shows the appearance of the wire 12 formed from a single plate so as to repeat the above-mentioned slot accommodating portion 12c and turn portion 12b. Each of the U-phase wire 12U, the V-phase wire 12V, and the W-phase wire 12W is formed from a single plate in the same manner as the wire 12. In FIG. 3, the stator core 11 is also shown by a two-dot chain line for reference.

FIG. 4 shows a state when the wire 12 is disposed in the slot 13 of the stator core 11 as viewed from the side of the stator core 11. As shown in FIG. 4, the turn portions 12 b of the wire 12 arranged in the same slot 13 (for example, the slot 13 a) have the same height H protruding from the end surface 11 a of the stator core 11. As shown in FIG. 1, the convex portions 12a of the turn portions 12 (for example, the U-phase wire 12U and the V-phase wire 12V) of the wire 12 accommodated in different slots 13 (for example, the slot 13a and the slot 13b) are arranged in the circumferential direction. Configured to deviate.
Further, six Va parts shown in FIG. 4 are enlarged and shown in FIG. 5A, and eleven Vb parts similarly shown in FIG. 4 are enlarged and shown in FIG. 5B. The six Va portions look the same when viewed from different angles. The 11 Vb portions look similar when viewed from different angles, although the shape of the gap is somewhat different.

  The gap X1 shown in FIG. 5A is generated in the concave portion K when the wire 12 is arranged in a stacking direction in the stacking direction (the front-rear direction with respect to FIG. 5A). In other words, the space is surrounded by the laminated wire 12 and allows ventilation. The shape of the gap X1 depends on the shape of the convex portion 12a formed in the turn portion 12b. Since the wire 12 shown in FIG. 2A is formed in an arc shape, the gap X1 in FIG. 5A has a triangular shape (having a slightly curved bottom). The gap X1 generated in this way becomes a place for heat to escape and the wind easily passes.

  The gap X2 shown in FIG. 5 (B) is a space that can be ventilated when the wires 12 are arranged in the stacking direction in the stacking direction, like the gap X1 described above. The difference from the gap X1 is that the gap X1 is generated by the shape of the convex portion 12a (that is, the concave portion K), whereas the gap X2 is generated by a predetermined distance L that causes the in-slot housing portion 12c to protrude from the end surface 11a. Yes (see also FIG. 2A). The gap X2 in FIG. 5B has a substantially pentagonal shape. The gap X2 generated in this way becomes a place for heat to escape as in the gap X1 described above, and the wind easily passes.

  A configuration example of the rotating electrical machine including the stator 10 described above will be described with reference to FIG. This rotating electric machine corresponds to, for example, an electric motor. A rotating electrical machine M shown in FIG. 6 includes a frame (housing) 1, a rotor 3, a shaft (rotating shaft) 5, and the like in addition to the stator 2 corresponding to the stator 10 described above. That is, in the frame 1, a stator 2 (a stator 10 around which a wire 12 is wound) is provided, and a shaft 5 to which the rotor 3 is fixed is rotatably provided (for example, in an arrow Dr direction). The stator 2 and the rotor 3 are opposed to each other, and a rotating magnetic field is generated by conduction to the coil 4 wound around the stator 2, and the rotor 3 and the shaft 5 are rotated in accordance with the rotating magnetic field. Therefore, the rotary electric machine M provided with the characteristics of the stator 10 described above can be provided.

According to the embodiment described above, the following effects can be obtained. First, the wire 12 is accommodated in the slot 13 of the stator core 11 and in-slot storage part 12c, and in-slot storage part 12c and in-slot storage part accommodated in another slot 13 apart from the slot 13 by a predetermined pitch. 12d, and is configured to include a turn portion 12b formed to protrude from the end surface 11a of the stator core 11 (see FIG. 2A). The turn portion 12b is formed into a slot 13 having a concave portion K which is partially bent in a protruding shape in the width direction of the wire 12 and protruding from the end surface 11a, and which is bent into a concave shape on the opposite side in the width direction. It has the structure which has the convex-shaped part 12a which is dented and formed in the protrusion direction rather than the intermediate part of the other turn part 12b which is accommodated and passes the end surface 11a side of the stator core 11 ( FIG. 1, FIG. 2 (A), (See FIG. 5A). According to this configuration, the convex part 12a of the turn part 12b has a concave part (inner part) that is recessed from the other turn part 12b (more specifically, the end face of the intermediate part in the protruding direction). Becomes a passage for the wind, making it easier to escape the generated heat. Therefore, the performance of the stator 10 can be suitably maintained.

  Further, the convex portion 12a is formed in an arc shape (see FIG. 2A and the like). According to this configuration, the convex portion 12a can be formed by bending the turn portion 12b partially into an arc shape. Therefore, the invention can be simply configured with a low cost.

  Further, the convex portion 12a is provided at a substantially central portion of the turn portion 12b (see FIG. 2A and the like). According to this configuration, the turn portion 12b is substantially symmetric with respect to the convex portion 12a, so that the turn portion 12b can be easily accommodated in the slot 13 of the stator core 11. Therefore, workability in the manufacturing process of the stator 10 can be improved.

  Further, the turn portion 12b is configured to be formed in a substantially linear shape within a predetermined width W except for the convex portion 12a (see FIG. 2B). According to this configuration, if it is within the range of the predetermined width W, characteristics equivalent to those formed linearly can be obtained. Moreover, since the part which protrudes from the end surface 11a of the stator core 11 can be decreased by forming in substantially linear form, and the length of the whole wire 12 can be restrained short, electrical resistance is decreased and the performance of the rotary electric machine M is improved. be able to.

  Further, the turn portion 12b is formed so as to extend with a predetermined angle θ with respect to the end surface 11a of the stator core 11 from the boundary portion with the in-slot housing portion 12c (see FIG. 2A). ). According to this configuration, a gap can be secured between the turn portion 12b and the end surface 11a as the distance from the in-slot storage portion 12c increases. Since this gap is secured also in the laminating direction in which the plurality of wires 12 are laminated, it releases heat and also serves as a wind path. Therefore, the heat generated in the wire 12 and the like can be easily released more reliably, and the performance of the rotating electrical machine M can be easily maintained.

  Further, the in-slot housing portion 12c is configured to protrude from the end face 11a of the stator core 11 by a predetermined distance L (see FIG. 2A). According to this configuration, the entire turn portion 12b generates a gap X2 corresponding to the predetermined distance L (see FIG. 5B). The gap X2 releases heat and also serves as a wind path. Therefore, the heat generated in the wire 12 and the like can be easily released more reliably, and the performance of the rotating electrical machine M can be easily maintained.

Further, the wire 12 is laminated in the radial direction in the slot 13, and the turn portion 12b of the wire 12 accommodated in the same slot 13 (for example, the slot 13a) has the same height H protruding from the end surface 11a of the stator core 11. Yes, the convex portions 12a of the turn portions 12b of the wire rods 12 accommodated in different slots 13 (for example, the slot 13a and the slot 13b) are shifted in the circumferential direction, and at least one convex portion 12a of the laminated wire rods 12 is provided. It was set as the structure which produces the clearance gap X1 toward a radial direction (refer FIG.1 , FIG.4, FIG.5 (A)). According to this configuration, since air flows through the gap X1 generated at least at one place, the stator 10 can be reliably cooled, and the performance of the rotating electrical machine M can be maintained.

  Further, the wire 12 (U-phase wire 12U, V-phase wire 12V, W-phase wire 12W) is formed of a single continuous plate for each of the U-phase, V-phase, and W-phase (see FIG. 3). reference). According to this configuration, since the wire 12 is formed of a single continuous plate, there is no connection portion, so that an increase in resistance due to connection can be prevented, and suitable performance of the rotating electrical machine M can be maintained. In addition, the number of parts can be reduced.

  The wire 12 was formed using a coated copper body or a coated aluminum material. Regardless of which is used as the wire rod 12, the same electric resistance can be obtained. Further, since the wire 12 itself is soft, the assembling property of the wire 12 into the slot 13 is extremely improved.

  The rotating electrical machine M includes a stator 10 in which a wire 12 (U-phase wire 12U, V-phase wire 12V, and W-phase wire 12W) is disposed in a slot 13 as the stator 2 (see FIG. 6). ). According to this configuration, heat generated by the wire 12 constituting the stator 10 can be easily released, so that the performance of the entire rotating electrical machine M can be suitably maintained.

[Other Embodiments]
Although the form for implementing this invention was demonstrated above, this invention is not limited to the said form at all. In other words, various forms can be implemented without departing from the scope of the present invention. For example, the following forms may be realized.

  In the above-described embodiment, the convex portion 12a is formed in an arc shape (see FIG. 2, FIG. 3, etc.). Instead of this form, another shape may be used. Other shapes include a “∩” shape shown in FIG. 7A, a “Λ” shape shown in FIG. 7B, and a multi-step staircase shape shown in FIG. 7C. In addition, any shape that is bent in a protruding direction in the protruding direction and the recessed portion K is recessed in the protruding direction from the other turn portions may be used. Even when formed in other shapes as described above, air flows through a gap generated at least at one place in the radial direction (= projection direction). Therefore, the stator 10 can be reliably cooled, and the performance of the rotating electrical machine M including the stator 2 corresponding to the stator 10 can be maintained.

  In the above-described embodiment, the convex portion 12a is provided in the substantially central portion of the turn portion 12b (see FIGS. 2 and 3). Instead of this form, it is a condition that the concave portion K accompanying the provided convex portion 12a is recessed in the protruding direction from the other turn portions, but the convex portion 12a is provided on the turn portion 12b in the portion other than the central portion. It may be provided. Thus, even when it is provided in a portion other than the central portion, air flows through a gap generated at least one portion in the radial direction. Therefore, the stator 10 can be reliably cooled, and the performance of the rotating electrical machine M including the stator 2 corresponding to the stator 10 can be maintained.

  In the above-described embodiment, the turn portion 12b is formed to extend from the boundary portion with the in-slot housing portion 12c with a predetermined angle θ with respect to the end surface 11a of the stator core 11 (FIG. 2). , See FIG. Instead of this form, the turn portion 12b may be formed so as to extend from the boundary portion with the in-slot housing portion 12c without having the predetermined angle θ. In other words, θ = 0 degrees, and it is formed substantially parallel to the end face 11a. Although the gap generated between the end surface 11a is reduced, air flows through the gap generated at least at one location in the radial direction. Therefore, the stator 10 can be reliably cooled, and the performance of the rotating electrical machine M including the stator 2 corresponding to the stator 10 can be maintained.

  In the above-described embodiment, the wire 12 (U-phase wire 12U, V-phase wire 12V, W-phase wire 12W) is formed of one continuous plate material for each of the U-phase, V-phase, and W-phase. (See FIG. 3). Instead of this configuration, it is also possible to employ a configuration in which a single continuous thin line is formed from a twisted line. Even if it is a twisted line, each thin line is continuous, so there is no connection point and it is possible to prevent an increase in resistance due to the connection. Therefore, it is possible to maintain a suitable performance of the rotating electrical machine M and reduce the number of parts. It is also possible to do. In addition, about any of a board | plate material and a stranded wire, it can apply similarly also when comprised by the number of phases other than three phases (for example, two phases or four phases or more), and the same effect as the case of three phases is obtained. be able to.

  In the embodiment described above, the rotating electrical machine M is used as an electric compressor (electric motor) (see FIG. 6). Instead of this form, an electric motor that is rotationally driven by a device other than the electric compressor, or another rotating electric machine such as a generator or a generator motor may be configured. Even when another rotating electrical machine is configured, air flows through a gap generated at least in one radial direction, and the performance of the rotating electrical machine M including the stator 2 corresponding to the stator 10 can be maintained. .
