Description

  The present invention relates to a stator constituting a rotating electrical machine, a rotating electrical machine including the stator, and a compressor equipped with the rotating electrical machine.

  In a refrigeration cycle apparatus such as an air conditioner equipped with a refrigeration cycle, a compressor is provided as one element device. Such a compressor is usually mounted with a rotating electric machine (electric motor) as a drive mechanism for compressing fluid. This rotating electrical machine is composed of a rotor that is attached to a rotating shaft and that can be driven to rotate together with the rotating shaft, and a stator that is arranged with a gap around the outer periphery of the rotor. In recent years, for the purpose of reducing power consumption and improving productivity of rotating electrical machines, the use of concentrated winding type stators in which the laminated iron cores are wound via insulating members and the laminated iron cores are combined. Has increased.

  In such a concentrated winding type stator, each winding is connected so as to generate a rotating magnetic field. Further, in the concentrated winding type stator, the end of each winding (neutral point side lead wire, power source side lead wire) is connected, so that the neutral point and input line (U phase, V phase, W phase). One connection method at the neutral point of each winding uses a connection terminal.

  For example, to connect the neutral points of three-phase windings, a technology that uses a terminal with two slots to insert and connect one winding and two jumper wires is proposed. (For example, refer to Patent Document 1).

  In addition, a technique has been proposed in which three terminals having one slot are used in a connected state, and windings of different phases are inserted and connected to each slot (for example, see Patent Document 2).

Japanese Patent No. 4271003 (pages 3 to 6, FIG. 4 etc.) Japanese Patent No. 3721119 (pages 3-8, FIGS. 4, 5, etc.)

  Since the connection by the connection terminal as described in Patent Document 1 is connected to the terminal having two slots using one winding and two jumper wires, the cost of the jumper wires is extra. This was one factor in the cost increase.

  In addition, since the connection by the connection terminal as described in Patent Document 2 is made by connecting three terminals in one slot in succession, the jumper wire is used to connect by extending the winding. Although it becomes unnecessary, the size of the terminal increases, and consequently the size of the stator must be increased. Therefore, it becomes an obstacle to miniaturization of products (such as rotating electrical machines and compressors) provided with a stator.

  The present invention has been made to solve the above-described problems, and is a stator of a rotating electrical machine designed to realize cost reduction and space saving, a rotating electrical machine including the stator, and An object of the present invention is to provide a compressor having a rotating electrical machine including the stator.

  A stator of a rotating electrical machine according to the present invention includes a stator core, a plurality of windings applied to the stator core via an insulating member, and one slit, and each phase of the winding A connection terminal that electrically connects a neutral point, and a connection terminal insertion hole that is formed in a part of the insulating member or a resin member different from the insulating member, and in which the connection terminal is mounted, The winding connected to the first phase has the tip on the neutral point connection side disposed in the connection terminal insertion hole of the second phase, and the winding connected to the second phase has the neutral point connection side The winding connected to the third phase through the second phase connection terminal insertion hole, the tip side of which is disposed in the third phase connection terminal insertion hole, has a neutral point connection side on the third phase. Each of the second phase connection terminal insertion hole and the third phase connection terminal insertion hole. By mounting the connecting terminals, in which connecting a phase of the neutral point.

A rotating electrical machine according to the present invention includes the above-described stator and a rotor that generates torque by being combined with the stator.
A compressor according to the present invention includes the above rotating electric machine, a compression mechanism that compresses a fluid by the rotating electric machine, and a sealed container that houses the rotating electric machine and the compression mechanism.

  According to the stator of the rotating electrical machine according to the present invention, a neutral point connection of a three-phase winding is realized with two connection terminals by connecting two windings with a connection terminal having one slit. As a result, the number of connection terminals can be reduced and a jumper line is not required, so that low cost and space saving can be realized.

According to the rotating electrical machine of the present invention, since the stator is provided, the same effect is obtained.
According to the compressor according to the present invention, since the above-described rotating electric machine is mounted, the same effect can be achieved and the size of the sealed container can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a schematic diagram for explaining a neutral point connection of the stator 50 according to the first embodiment of the present invention. FIG. 2 is a schematic diagram schematically showing the structure of the insulator 2 of the stator 50. FIG. 3 is a perspective view showing the structure of the insulator 2 of the stator 50. FIG. 4 is a schematic diagram showing a state when an excess portion of the winding 5 is cut. FIG. 5 is a side view showing a state after the excess portion of the winding 5 is cut. FIG. 6 is a side view schematically showing a state after the excess portion of the winding 5 is cut. FIG. 7 is an explanatory diagram for explaining the connection terminal 6. Based on FIGS. 1-7, the structure (especially connection of a neutral point) and operation | movement of the stator 50 are demonstrated. In addition, in the following drawings including FIG. 1, the relationship of the size of each component may be different from the actual one. Further, the surface of the stator 50 viewed in the direction perpendicular to the axis is viewed from the side, and the surface viewed in the direction parallel to the extension of the axis of the stator 50 is viewed in plan.

  The stator 50 according to the first embodiment uses two 1-slit connection terminals (hereinafter simply referred to as connection terminals 6) to connect the neutral points of the three-phase winding. The stator 50 is configured by combining a plurality of substantially T-shaped stator cores 1 in an annular shape. On the inner peripheral side of each stator core 1, a tooth portion around which the winding 5 is concentrated is formed so as to protrude. And in the state where stator core 1 was combined annularly, a predetermined gap is formed between adjacent tooth parts. As shown in FIG. 1, each stator core 1 has an insulator 2 mounted on the upper and lower surfaces thereof, and the winding 5 is concentratedly wound around the stator core 1 (specifically, a tooth portion) via the insulator 2. . The stator core 1 is configured by laminating a plurality of iron cores.

  One end of the winding 5 is a power supply side lead line connected to the power source, and the other end of the winding 5 is a neutral point side lead line connected to the neutral point side. That is, the winding 5 is connected to the neutral point side lead wire of each layer and Y-shaped connection is performed. Note that the winding 5 is shown only in the portion related to the neutral point connection, and the concentrated winding is not shown. In addition, the left stator core 1 shown in FIG. 1 is the stator core 1A, the center stator core 1 is the stator core 1B, and the right stator core 1 is the stator core 1C. A to C will be described. However, when it is not necessary to distinguish the stator core 1 in particular, A to C are not attached.

  A connection terminal insertion hole 3 is provided on a part of the upper surface (the upper surface of the paper) of the insulator 2. Winding 5A passes through connection terminal insertion hole 3A formed in the upper surface of insulator 2A, and reaches connection terminal insertion hole 3B of adjacent insulator 2B (insulator 2 adjacent to the right side in FIG. 1). Be placed. As a result, one winding 5A is arranged in the connection terminal insertion hole 3A, and two windings 5 are arranged in the remaining two connection terminal insertion holes 3. Specifically, the winding 5A and the winding 5B are arranged in the connection terminal insertion hole 3B, and the winding 5B and the winding 5C are arranged in the connection terminal insertion hole 3C, respectively. Thereafter, the connection terminals 6 are inserted into the two connection terminal insertion holes 3 where the two windings 5 are arranged.

  The connection terminal 6 has one terminal slit 6a as shown in FIG. 7A (if the terminal as shown in FIG. 7B has a thin plate bending structure, slits are formed at two locations on the front and back sides. However, when the terminal has a single plate structure, literally only one slit is formed.) When the connection terminal 6 is inserted into the connection terminal insertion hole 3 through which the winding 5 is passed, the two windings 5 are attached to the terminal slit 6a, and the two windings 5 are mutually connected via the connection terminal 6. Connected to. As a result, the neutral point of each phase can be connected. The shape of the connection terminal 6 is not limited to that shown in FIG. 7, and a terminal having a similar function may be used as the connection terminal 6.

  As shown in FIG. 3, the connection terminal insertion hole 3 is provided with a slit 7 for passing the winding 5 and holding it at an appropriate position. Then, the surplus portion of the winding 5 (the surplus portion 5b shown in FIG. 4) is cut at an appropriate position. One end side (neutral point connection side) of the winding 5 extends to the right insulator 2 to be connected to the winding 5 of the adjacent stator core 1, but does not need to extend to the right insulator 2. When the surplus portion 5b is generated, the cut end of the conductor is exposed, and if left as it is, there is a possibility of contact with a metal frame (not shown). Therefore, the surplus portion 5b is cut so that the conductor exposed portion can maintain an appropriate insulation distance.

  At this time, since the two windings 5 are in one terminal slit 6a, the two windings 5 are in contact with each other in the vertical direction. There is a high possibility that the winding 5 connected to other phases will be cut or damaged. Therefore, in the stator 50, the winding separation holding mechanism 4 is provided in the vicinity of the slit 7 of the insulator 2 so that only one of the windings 5 can be cut without damaging the other of the two windings 5. It is possible to bend the other winding 5 without bending the two windings 5 and to separate the two windings 5 at an appropriate distance. In addition, the cut position 8 shown in FIG. 4 represents the position which cuts the surplus part 5b of the coil | winding 5a.

Next, neutral point connection will be described.
The winding 5 on the side connected to the neutral point of each stator core 1 is passed through the slit 7 of the connection terminal insertion hole 3 formed in the insulator 2. However, in the stator core 1 </ b> A, since the connection terminal 6 is not inserted, the winding 5 does not necessarily pass through the connection terminal insertion hole 3 and the slit 7. Further, the insertion hole 3 and the slit 7 itself may be omitted. Then, the tip side is passed through the connecting terminal insertion hole 3 of the adjacent insulator 2. Specifically, the winding 5A of the stator core 1A passes through the connection terminal insertion hole 3A of the insulator 2A, and then passes through the connection terminal insertion hole 3B of the insulator 2B. Similarly, the winding 5B of the stator core 1B passes through the connection terminal insertion hole 3B of the insulator 2B and then passes through the connection terminal insertion hole 3C of the insulator 2C. The winding 5A is passed through the connection terminal insertion hole 3B so as to be above the winding 5B (opening side of the connection terminal insertion hole 3), and the winding 5B is above the winding 5C. It passes through the connection terminal insertion hole 3C.

  Next, by inserting the connection terminal 6 into the two connection terminal insertion holes 3 (connection terminal insertion hole 3B, connection terminal insertion hole 3C) where the two windings 5 are arranged, the three windings 5 are connected to each other. Specifically, the winding 5A extending from the insulator 2A is connected to the winding 5B by the connection terminal 6 inserted into the insulator 2B, and the winding 5B extending from the insulator 2B is connected to the insulator 2C by the connection terminal 6 inserted into the insulator 2C. Connected to winding 5C. That is, since the winding 5 extending from the central insulator 2 connects the central insulator 2 and the connection terminal 6 of the right insulator 2, the three windings 5 can be electrically connected.

  The winding separation holding mechanism 4 separates the two windings 5 and also holds the upper and lower holding parts 4a (the upper holding part 4a1 and the lower holding part 4a2) holding one of the windings 5 and the windings extending to the adjacent insulators 2. And a groove 4b for guiding the wire 5. The upper and lower clamping parts 4 a can bend one of the windings 5 (for example, the winding 5 </ b> A passing through the connection terminal insertion hole 3 </ b> B) in a substantially horizontal direction (outer peripheral direction) at a predetermined angle with respect to the extending direction of the slit 7. And it is comprised so that it can hold | maintain at the place bent. That is, the winding 5 passed through the connection terminal insertion hole 3 is bent to the outer peripheral side at a predetermined angle, passed through the space between the upper and lower clamping parts 4a, and held by being clamped by the upper and lower plates. It is like that. Further, the upper and lower clamping parts 4a have a predetermined angle θ1 between the outer peripheral side surface and the inner peripheral side surface, and have a triangular shape when the stator 50 is viewed in plan view.

  In the case of the winding 5 using copper or aluminum as a conductor, a gap may be provided between the pinching portion (upper / lower clamping portion 4a) and the winding 5 in order to maintain the shape once bent. Further, the groove 4b does not necessarily have to be a groove. For example, a wall may be provided only on one side so as not to approach the winding 5 on the bent side. Furthermore, the shapes of the upper sandwiching portion 4a1 and the lower sandwiching portion 4a2 are not limited to triangles, and may be other shapes such as a quadrangle (for example, see FIG. 10).

  The groove 4 b is formed on the extension of the slit 7 and holds the winding 5 extending to the adjacent insulator 2. The winding separation holding mechanism 4 can easily separate the two windings 5. In addition, as shown in FIG.5 and FIG.6, the upper clamping part 4a1 is comprised by the plate-shaped member. Moreover, although the lower clamping part 4a2 has shown in the example the state comprised by the plate-shaped member in FIG. 5, as shown in FIG. 6, it is comprised as a shape connected to the upper surface side of the stator core 1 May be. If the lower sandwiching portion 4a2 has a shape as shown in FIG. 6, the area hit by the blade of a cutting mechanism such as a nipper is increased, and the stability of the cutting operation can be further improved.

  Therefore, after the winding 5 is bent and held, the surplus portion 5b can be cut at the cutting position 8 by operating the cutting mechanism along the outer peripheral side surface of the upper and lower clamping portion 4a. In addition, when it is desired to cut both of the windings 5 (winding 5B, winding 5C) as in the case of the insulator 2C, the two windings 5 are separated from each other, and then the windings 5 are provided at two locations. Just cut.

  It should be noted that the predetermined angle θ1 of the plate material constituting the winding separation holding mechanism 4 is necessary insulation between the cut end of the surplus portion 5b and another metal structure (for example, an oil pipe or a shell frame). What is necessary is just to determine so that distance can be ensured. Further, as the bending angle of the surplus portion 5b of the winding 5, the angle formed between the end face of the upper and lower clamping portion 4a and the winding 5 is preferably close to 90 °. By cutting the surplus part while applying the side of the blade to the outer peripheral surface of the sandwiching part, the cut cross section of the surplus part 5b becomes a shape close to a perfect circle, and the cross-sectional area is the smallest, so the force required for cutting is the least In addition, the protrusion of the cut end of the winding 5 can be minimized.

  By connecting the neutral points as described above, the number of connection terminals 6 used is 3 to 2 compared to the case where the neutral point side lead wires of each phase are connected by jumper wires and connection terminals. In addition, it is possible to reduce the number of components because a jumper line is unnecessary. Moreover, it becomes possible to adapt also to the small stator with which there is not enough space by using two connection places. In particular, since the stator is often shrink-fitted in the hermetic container, the rotating electrical machine according to the first embodiment can effectively use the space in the hermetic container, and can also reduce the size of the hermetic container. It will contribute greatly. Furthermore, since no jumper wires are used, the cost can be reduced accordingly.

Embodiment 2. FIG.
FIG. 8 is a schematic diagram schematically showing the structure of the insulator 20 of the stator 60 according to the second embodiment of the present invention. FIG. 9 is a side view schematically showing a state after cutting an excess portion of the winding 5. Based on FIG.8 and FIG.9, the structure (especially connection of a neutral point) and operation | movement of the stator 60 are demonstrated. In the second embodiment, differences from the first embodiment will be mainly described, and the same parts as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted. The stator 60 has the same configuration and function as the stator 50 described in the first embodiment.

  The stator 60 according to the second embodiment is effective when there is a relatively large space in the upper space of the stator core 1. The stator 60 also has a winding separation holding mechanism 40. The configuration of the winding spacing / holding mechanism 40 is different from the configuration of the winding spacing / holding mechanism 4 described in the first embodiment. Specifically, the winding separation and holding mechanism 4 described in the first embodiment is configured to bend the winding 5 in a substantially horizontal direction to promote cutting of the surplus portion 5b. The wire separation holding mechanism 40 is configured to bend the winding 5 upward (in a direction other than the iron core side) and promote cutting of the surplus portion 5b.

  The winding separation holding mechanism 40 separates the two windings 5 and holds one winding 5 while holding the left and right clamping portions 40a (the outer circumferential side clamping unit 40a1 and the inner circumferential side clamping unit 40a2) and the adjacent insulator 20. And a groove 40b for guiding the winding 5 extending in the direction. The left and right clamping portion 40a can bend one of the windings 5 (for example, the winding 5A passing through the connection terminal insertion hole 3B) upward at a predetermined angle with respect to the extending direction of the slit 7. By the way, it is comprised so that it can hold | maintain. That is, the winding 5 passed through the connection terminal insertion hole 3 is bent at a predetermined angle, is passed through the space between the outer peripheral side clamping part 40a1 and the inner peripheral side clamping part 40a2, and is sandwiched between the left and right plates. To be retained. Further, the left and right clamping portion 40a is inclined with a predetermined inclination angle θ2 on the cut side surface of the surplus portion 5b, and has a triangular shape when viewed from the outer peripheral side surface.

  The groove 40 b is formed on the extension of the slit 7 and holds the winding 5 extending to the adjacent insulator 20. The winding separation holding mechanism 40 can easily separate the two windings 5. In addition, as shown in FIG.8 and FIG.9, the right-and-left clamping part 40a is comprised integrally with the slit 7. As shown in FIG. A cut position 80 shown in FIG. 9 represents a position where the surplus portion 5b of the winding 5a is cut so as not to extend to the adjacent stator core 1. Further, as shown in FIGS. 8 and 9, an example is shown in which the winding separation holding mechanism 40 is in a position opposite to the winding separation holding mechanism 4 of the first embodiment with respect to the connection terminal insertion hole 3. However, it goes without saying that it may be installed on either the left or right side of the connection terminal insertion hole 3 (the same applies to the first embodiment).

  Therefore, after the operator bends and holds the winding 5, the operator operates the cutting mechanism along the holding portion (the cut-side side surface of the surplus portion 5b of the left and right clamping portion 40a), so that the surplus portion at the cut position 80 is obtained. 5b can be cut. In addition, when it is desired to cut both of the windings 5 (winding 5B, winding 5C) as in the case of the insulator 2C, the two windings 5 are separated from each other, and then the windings 5 are provided at two locations. Just cut.

  In addition, the predetermined inclination angle θ2 of the left and right clamping portions 40a constituting the winding separation holding mechanism 40 is easy to cut the surplus portion 5b bent upward, and the cut cross section and other metal structures What is necessary is just to determine so that an insulation distance can fully be ensured. Further, as the bending angle of the surplus portion 5b of the winding 5, it is desirable that the angle formed between the end face of the left and right sandwiching portion 40a and the winding 5 is close to 90 °. Then, the cut section of the surplus portion 5b has a shape close to a perfect circle, and the sectional area becomes the smallest. Therefore, the force required for cutting is minimized, and the protrusion of the cut end of the winding 5 is minimized. Can be suppressed.

  By connecting the neutral points as described above, the number of connection terminals 6 used is 3 to 2 compared to the case where the neutral point side lead wires of each phase are connected by jumper wires and connection terminals. In addition, it is possible to reduce the number of components because a jumper line is unnecessary. Moreover, it becomes possible to adapt also to the small stator with which there is not enough space by using two connection places. In particular, since the stator is often shrink-fitted in the hermetic container, according to the rotating electrical machine according to the second embodiment, the space in the hermetic container (especially the stator 60) even when there is no margin in the outer circumferential direction. The upper space) can be effectively utilized, and also greatly contributes to the downsizing of the sealed container. Furthermore, since no jumper wires are used, the cost can be reduced accordingly.

  In the first embodiment and the second embodiment, the stator is shown as an example in which concentrated winding is performed using a split iron core. However, the stator is not limited to such a stator, and an integral iron core is also used. Needless to say, the same effect can be obtained. Moreover, in Embodiment 1 and Embodiment 2, although the example which inserted the connecting terminal 6 in the insulator 2 which is an example of an insulating member was shown, by preparing insulating members, such as resin molded products other than the insulator 2, it is. Needless to say, the present invention can be applied to a stator having no insulator. Furthermore, the neutral point connection shown in the first embodiment and the second embodiment is an example, and the same effect can be obtained even when the combination of the U phase, the V phase, and the W phase is changed.

  Further, if the rotating electric machine is provided with the stator 50 described in the first embodiment or the stator 60 described in the second embodiment, the effect exerted by the stator 50 or the stator 60 is similarly obtained. . Therefore, it is possible to reduce the manufacturing cost of the rotating electrical machine. The rotating electric machine includes a rotor that generates torque by being combined with the stator 50 or the stator 60.

  Furthermore, if the rotary electric machine provided with the stator 50 described in the first embodiment or the stator 60 described in the second embodiment is mounted on the compressor, the effects of the stator 50 or the stator 60 are similarly obtained. It will be. Therefore, it is possible to reduce the manufacturing cost of the compressor. Further, in the compressor, it is possible to reduce the size of the sealed container. In addition to the rotating electrical machine, the compressor includes a compression mechanism unit that compresses fluid by the rotating electrical machine, and a sealed container that houses the rotating electrical machine and the compression mechanism unit.
