Abstract

<P>PROBLEM TO BE SOLVED: To provide an edgewise type coil capable of attaining size reduction and high reliability. <P>SOLUTION: The edgewise type coil is formed by bending a straight angle copper wire in a width direction. The inside 12 of a bent portion is swollen to increase its thickness by compression stress. The bent portion of the edgewise type coil 10 is set so that the inside 12 of the bent portion of a first winding wire which is one winding from an end 14 may not be overlapped with the bent portion of a second winding wire which is one winding following the first winding wire with each other. Because the inner side 12 of the bent portion is displaced by the adjacent winding, swollen portions of the bent portion do not face each other to restrain the total thickness of the coil. Besides, insulation coats which are deformed at the swollen portions of the bent portion do not face each other, therefore liability is improved by a pressure proof surface. Moreover, coil outer peripheries are alternately disposed, thus increasing a surface area for a favorable radiation surface. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a coil of an edgewise type rotating electrical machine, a rotating electrical machine including an edgewise type coil, and a method of manufacturing the coil.

  2. Description of the Related Art Conventionally, an edgewise coil is known that bends in a width direction that is difficult to bend rather than a thickness direction that is easily bent with respect to a strip of a flat conductor. An edgewise type coil is sometimes called a vertical winding coil. The edgewise type coil uses a rectangular wire instead of a round wire, so that the space factor is improved and the resistance value is low. In addition, since it is not wound in multiple layers, there is a feature that the temperature difference between the inside and outside of the winding is small and heat dissipation is good.

For example, a motor using such an edgewise coil as a rotor is disclosed in Japanese Patent Laid-Open No. 10-42502 (Patent Document 1).
Japanese Patent Laid-Open No. 10-42502 JP 11-98744 A

  When the strip of the flat conductor is bent in the width direction, the outer peripheral portion extends, and conversely, compressive stress acts on the inner peripheral portion. The inner peripheral portion tends to swell due to such compressive stress. The rectangular wire used for the edgewise coil is usually provided with an insulating coating on its surface with enamel or the like. This insulating coating is deformed at the surface portion that is swollen when force is applied during processing or the like, resulting in uneven thickness.

  In the conventional structure of a coil that is aligned and bent at the same position, the bulging portion of the inner periphery due to bending overlaps in the winding direction of the winding, and there is a possibility that insulation between the coils of the coil may be reduced. .

  For this reason, in Unexamined-Japanese-Patent No. 10-42502 (patent document 1), the insulating member is arrange | positioned between the wires of the wound coil. However, the installation of such an insulating member has a problem that the coil further expands in the stacking direction and the size increases.

  Further, in order to obtain a heat dissipation effect, in Japanese Patent Application Laid-Open No. 10-42502, the shape of the element wire is processed by providing a notch or the like, but it is costly to process the element wire in order to obtain a heat dissipation effect. In addition, there is a problem that the electromagnetic characteristics of the motor are deteriorated because the electrical resistance of the coil is increased.

  The present invention relates to a coil of a rotating electrical machine in which the reliability is improved while reducing the size without impairing the electromagnetic characteristics of the motor, and more preferably, the heat dissipation effect is enhanced, the rotating electrical machine including the coil, and a method of manufacturing the coil Is to provide.

  In summary, the present invention relates to a coil of an edgewise type rotating electrical machine that bends a strip of a flat conductor in the width direction of the strip, and includes a first bent portion that is bent, and a first bent portion. And a second bent portion arranged next to the coil stacking direction, and the positions of the inner portions of the first bent portion and the second bent portion are arranged so as to be shifted from each other in the plane direction of the flat conductor. Yes.

  The coil of the edgewise type rotating electrical machine that bends the strip of the flat conductor according to another aspect of the present invention in the width direction of the strip, each of which is one turn, and includes a plurality of winding portions arranged in order, The odd-numbered winding part and the even-numbered winding part among the plurality of winding parts have different bending positions.

  Preferably, at least a part of the odd-numbered winding portion and the even-numbered winding portion among the plurality of winding portions are different in outer peripheral position.

  Preferably, each winding portion has a quadrangular shape and has four corner portions that are bent.

  More preferably, among the four sides of the quadrangle, predetermined one sides corresponding to each winding portion form a coil end portion, and further include a resin mold that covers the coil end portion.

  Preferably, the strip of the flat conductor is previously coated with an insulating material.

  According to still another aspect of the present invention, a rotating electrical machine includes any one of the above rotating electrical machine coils.

  According to still another aspect of the present invention, there is provided an edgewise coil manufacturing method for bending a strip of a flat conductor in the width direction of the strip, the split portion of the bending mold having a plurality of adjacent split portions. A first step of winding a strip of a flat conductor along a combination of some of the above and any one of a plurality of divisions, or a combination of divisions different from the combination of the first steps And a second step of winding a flat conductor strip along the line.

  ADVANTAGE OF THE INVENTION According to this invention, the swell of a coil lamination direction is reduced and an edgewise type | mold coil with a small dimension is realizable.

  Moreover, the insulation fall between coil wires is prevented and reliability improves.

  Furthermore, the heat dissipation effect is improved and the temperature rise of the coil can be prevented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.

[Embodiment 1]
FIG. 1 is a diagram showing the structure of a rotating electrical machine to which the coil of the present invention is applied.

  With reference to FIG. 1, the cross section perpendicular | vertical to the rotating shaft of the rotary electric machine 1 is demonstrated. The rotating electrical machine 1 includes a shaft 4 that is a rotating shaft, a rotor 3 that is coupled to the shaft 4, and a stator 2 that is fixed to a case (not shown).

  The stator 2 is formed by laminating electromagnetic steel plates, for example. The stator 2 is provided with twelve protrusions 5. A coil 10 is wound around the protrusion 5 of the stator 2.

  A rotor 3 is accommodated in a cavity inside the stator 2. The rotor 3 is formed by laminating electromagnetic steel plates, for example, and permanent magnets 7 are arranged in eight cavities provided in the electromagnetic steel plates.

  When a three-phase alternating current is applied to the coil 10, the rotor 3 rotates about the center of the shaft 4 as a rotation axis by a force generated between the coil 10 and the permanent magnet 7.

  In addition, although the case where the rotary electric machine 1 is a motor has been described, it may be a generator that generates electricity in the coil of the stator by rotating the rotor by an external force. Moreover, in FIG. 1, although the coil is arrange | positioned at the stator, the case where a coil is arrange | positioned at the rotor side may be sufficient.

  FIG. 2 is a view for explaining the relationship between the coil 10 and the stator 2 in FIG. 1.

  Referring to FIG. 2, stator 2 is formed by laminating electromagnetic steel sheets, for example. This electromagnetic steel sheet is provided with protrusions. A coil 10 wound in advance is fitted into a substantially rectangular parallelepiped protrusion 5 formed by integrating the protrusions of an electromagnetic steel sheet.

  When the coil and the electromagnetic steel plate are fixed by a resin mold after the coil 10 is fitted, or when the coil 10 is fitted and a slip prevention ring is fitted to the tip of the projection 5, May be fixed.

  FIG. 3 is a diagram for explaining the shape of the coil 10 in detail.

  FIG. 4 is a side view of the coil when viewed from the direction A in FIG. 3.

  FIG. 5 is a side view of the coil 10 when viewed from the B direction in FIG. 3.

  3 to 5, the coil 10 is an edgewise coil obtained by bending a strip of a flat conductor in the width direction of the strip, and each turn has a quadrangular shape. In this specification, as shown in FIG. 3, even when the corner portion is bent with a certain curvature and does not have a corner strictly, when it can be determined as a rectangle as a whole, I will call it. Each turn is laminated in the coil lamination direction substantially orthogonal to the flat plate portion of the flat conductor.

  In FIG. 3, the coil 10 has one end positioned at the top starting from the end portion 14, and the one turn positioned below the coil 10 has a short side portion with a rectangular inner periphery on the inside. Further, the short side of the next roll is again in its original position.

  As a result, the coil end portion 11 has such a shape that the end points are counted from the end portion 14 side and the odd-numbered portion protrudes outside and the even-numbered portion enters inside. This portion has a fin-like shape with a large heat dissipation effect by passing air or cooling oil.

  And the inner part 12 of the bending part in each turn shifts between adjacent windings. As shown in FIG. 4, this shift appears as if a turn having a large diameter and a turn having a small diameter are alternately stacked. Further, as shown in FIG. 5, when viewed from the B direction, it appears that the turns having the same diameter are alternately stacked vertically.

  FIG. 6 is a view for explaining the displacement of the inner portion 12 of the bending portion of the present invention.

  Referring to FIG. 6B, when the bending positions are aligned so that the outer circumferences of adjacent windings are aligned as in the conventional case, the bulge 112 on the inner side of the bending portion is opposed to the adjacent windings at the coil end portion. As a result, the distance between adjacent windings cannot be brought into close contact.

  In addition, the bulging part inside the bent part may cause unevenness in the thickness of the insulating film such as enamel on the surface due to deformation during the bending process. May reduce the withstand voltage between the windings.

  On the other hand, as shown in FIG. 6A, the edgewise coil of the present invention is bent so that the inner portions 12 of the bent portion do not overlap with each other in the coil end portion. . The inner portion of the bent portion of the second winding from the left is shifted downward in the drawing with respect to the inner portion of the bent portion of the leftmost winding in FIG. Further, the inner portion of the bent portion of the third winding from the left is shifted upward in the drawing with respect to the inner portion of the second winding from the left in FIG. The vertical direction in FIG. 6A is a direction along the plane of the flat conductor. That is, the adjacent bent portions are arranged so as to be displaced from each other in the plane direction of the flat conductor.

  FIG. 7 is a cross-sectional view of the coil end portion shown in FIG. This section is a sectional view showing a section VII-VII in FIG.

  As can be seen by comparing FIG. 6A and FIG. 6B, in the case of FIG. 6A, the bending position is shifted, so that the windings can be more closely attached to each other. As a whole, the thickness of the coil can be reduced by an extra bulge ΔT. Further, since the insulating portions deformed by the stress during bending are not opposed to each other, the withstand voltage between adjacent windings can be improved as compared with the case shown in FIG.

  FIG. 8 is a view showing a mold 20 used for manufacturing the coil of the present invention.

  Referring to FIG. 8, a mold 20 is for forming an edgewise coil by winding a flat conductor band, and can be divided into divided parts 21, 22 and 23.

  The dividing parts 21, 22 and 23 are protrusions protruding from the base, and when winding one turn starting from the end part 14 in FIG. 3, the dividing parts 21, 22 and 23 protrude from the base. . A strip of a flat conductor is wound around the integrated divided portions 21, 22, and 23 by one turn.

  When the next round is wound, the dividing portions 21 and 23 are in a state in which only the drawing dividing portion 22 protrudes from the base inside the base. In this state, the one-turn coil is further wound.

  Subsequently, the divided portions 21 and 23 again protrude from the base by the thickness of the strip of the flat conductor, and the one-turn coil is wound around the outer periphery of the divided portions 21, 22 and 23 integrated.

  By repeating such steps, the coil is rolled up from the base, and the edgewise coil as shown in FIGS. 3 to 5 is manufactured.

  Note that an edgewise coil is manufactured by alternately repeating the step of winding the coil one turn using the dividing parts 21 and 22 and the step of winding the coil one turn using the dividing parts 22 and 23. Also good.

[Embodiment 2]
FIG. 9 is a diagram showing a structure of an edgewise coil used in the second embodiment.

  Referring to FIG. 9, the coil end portion 11 of the edgewise coil wound around the protrusion portion 5 of the stator is covered with a resin mold 30. Since the shape of the coil is the same as that of the first embodiment, description thereof will not be repeated.

  Even when the resin mold 30 is applied, the outer periphery of the edgewise coil is staggered by adjacent windings, so that the contact area with the resin is increased and heat dissipation to the resin is promoted, and the coil temperature is increased. Can suppress the rise.

  For example, the temperature of the coil is T1, the temperature of the resin mold 30 is T2, and the temperature of the air or cooling oil that contacts the resin mold 30 is T3. When the coil is energized, the coil generates heat due to the resistance component of the coil. Since the coil is a heat source, it can be said that the relationship of T1> T2> T3 always holds.

  Accordingly, the larger the contact area of the coil with the resin mold 30 whose temperature is lower than that of the coil, the better the heat dissipation effect. Therefore, even when the edgewise coil described in the first embodiment is resin-molded, the temperature rise of the coil can be suppressed.

  As described above, in the present invention, the edgewise coil is wound with a step at the coil end portion. Thereby, since the bulge of a bending part does not oppose, the bulge of a coil lamination direction can be reduced and the thickness of the whole coil can be made thin. Moreover, since the deformation | transformation part of the insulation coating in a bending part does not oppose, the insulation fall between lines can be prevented. Further, since the surface area of the coil end portion is increased, the heat dissipation effect can be improved. Furthermore, since no separate parts or additional processing are required for insulation or heat dissipation, a heat dissipation effect and an insulation improvement effect can be realized at low cost.

  In addition, although the example which applied the edgewise type | mold coil of this invention to the stator of the rotary electric machine was shown in FIG. 1, you may apply to the rotor side. Further, in FIG. 3, the edgewise coil has been described by taking a square shape suitable for application to a rotating electrical machine as an example, but even when used for other purposes or when used for a rotating electrical machine, A shape other than a square, for example, a round shape as a whole may be used.

  3 to 5 are edgewise coils in which a single flat conductor is wound. However, when a plurality of coils divided into electric motors are arranged in the coil stacking direction, bending is performed. You may arrange | position so that a part may slip | deviate. Furthermore, the present invention can be applied even to a coil in which a plurality of flat conductors, for example, two flat conductors, are wound in a stacked state.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

It is a figure which shows the structure of the rotary electric machine to which the coil of this invention is applied. It is a figure for demonstrating the relationship between the coil 10 and the stator 2 in FIG. It is a figure for demonstrating the shape of the coil 10 in detail.
