CROSS REFERENCE TO RELATED APPLICATION

This application is a National Stage of International Application No. PCT/JP2008/068710 filed Oct. 16, 2008, claiming priority based on Japanese Patent Application No. 2007-272962, filed Oct. 19, 2007, the contents of all of which are incorporated herein by reference in their entirety.

TECHNICAL FIELD

The present invention relates to a rotating electric machine, and particularly to a rotating electric machine including a plurality of divided stator cores, that achieves reduction in the number of parts and a smaller size.

BACKGROUND ART

Various types of rotating electric machines have conventionally been proposed in order to facilitate attachment of a winding. For example, a brushless motor described in Japanese Patent Laying-Open No. 2004-159427 includes radially extending teeth and a can coupling radially inward end portions of the teeth to one another and having a bottom portion closing one end formed, in which a winding is wound around each tooth. In attaching each winding to the teeth, a winding wound in advance to form a plurality of coils is attached to the teeth, so that the coils are simultaneously attached to the teeth. A crossing wire extending from a prescribed tooth to another tooth is disposed along the bottom portion of the can.

Thus, as compared with an example where each winding wound around each tooth is connected by using a connection member such as a bus bar, the number of parts can be decreased and connection can be facilitated.

In addition, a three-phase motor described in Japanese Patent Laying-Open No. 2002-199644 includes a stator including a coil assembly constituted of three-phase coils. A neutral point of each coil is connected to a bus bar formed of a conductive material and this bus bar is arranged on an outer side of the coil assembly. By thus arranging the bus bar around an outer circumference of the coil assembly, a bundle of connection lines of the neutral points and the neutral points are not adjacent to each other in a direction of axis of the coil assembly and reduction in an axial length of the motor is achieved.Patent Document 1: Japanese Patent Laying-Open No. 2004-159427Patent Document 2: Japanese Patent Laying-Open No. 2002-199644

DISCLOSURE OF THE INVENTION

Problems to be Solved by the Invention

In the brushless motor described in Japanese Patent Laying-Open No. 2004-159427, however, the can is an essential component and the number of parts cannot be reduced. In addition, as the crossing wire is disposed in the bottom portion of the can, reduction in the axial length is not sufficient.

In the three-phase motor described in Japanese Patent Laying-Open No. 2002-199644, distributed winding is adopted for the coil. In general, in distributed winding, a space factor of the coil is low and a length of one coil is long, which leads to great copper loss.

In order to provide means for solving such a problem, for example, a method of implementing a stator by forming a stator core with a plurality of divided stator cores is possible, a coil being wound around each divided stator core and the divided stator cores having the coils wound being annularly arranged. According to this method, as the coil is wound around each divided stator core, the space factor of the coil can be improved and a length of the coil can be reduced, so that copper loss can be reduced.

In the rotating electric machine including such a plurality of divided stator cores, however, coils attached to respective divided stator cores should be connected to each other. For example, a method of connecting the coils to each other through an annular power distribution member by arranging the annular power distribution member at a position adjacent to the stator in a direction of a central axis of the stator is possible as a method of connecting the coils.

Arrangement of such a power distribution member, however, leads to a longer length of the rotating electric machine in the direction of the central axis and the number of parts is further increased.

The present invention was made in view of the above-described problems, and an object of the present invention is to provide a rotating electric machine including a plurality of divided stator cores, that achieves reduction in the number of parts and a shorter length of the rotating electric machine in a direction of a central axis.

The projection portion above has a guide portion formed, for guiding the wiring portion from the winding portion to the yoke portion.

Preferably, the insulating member above includes a yoke insulating portion for insulating the wiring portion and the drawn-out portion from the yoke portion. Preferably, the coil wire above has a cross-section in a square shape perpendicular to a direction of extension of the coil wire, and the winding portion is structured by winding and layering the coil wire from a base portion of the stator teeth located on a side of the yoke portion toward a tip end portion thereof located radially inward of the stator. Preferably, the coil wire above includes a first coil wire supplied with AC power of a first phase and a second coil wire connected to the first coil wire and a third coil wire supplied with AC power of a second phase and a fourth coil wire connected to the third coil wire.

In addition, a fourth winding portion of the fourth coil wire above is arranged opposite to the third winding portion, with respect to the second winding portion, and a first wiring portion of the first coil wire is connected to a second drawn-out portion of the second coil wire through an outer circumferential side of the third winding portion. A third wiring portion of the third coil wire above is connected to a fourth drawn-out portion of the fourth coil wire through an outer circumferential side of the second winding portion, and a third drawn-out portion of the third coil wire extends radially outward of the stator between the first wiring portion and the yoke portion and bends in a direction of a central axis of the stator for receiving the first wiring portion on a side radially outward of the stator relative to the first wiring portion. The second drawn-out portion of the second coil wire above extends radially outward of the stator between the third wiring portion and the yoke portion and bends toward the direction of the central axis of the stator for receiving the third wiring portion on a side radially outward of the stator relative to the third wiring portion.

A plurality of divided stator cores150V1,150U1,150W1to150V6,150U6,150W6are aligned in the circumferential direction of stator130. Coils130V1,130U1,130W1to130V6,130U6,130W6formed by winding a part of coil wires230V1,230U1,230W1to230V6,230U6,230W6are attached to divided stator cores150V1,150U1,150W1to150V6,150U6,150W6, respectively. Coil wires230V1,230U1,230W1to230V6,230U6,230W6include coils130V1,130U1,130W1to130V6,130U6,130W6above, terminal portions135V1,135U1,135W1to135V5,135U5,135W5connected to inner end portions of these coils130V1,130U1,130W1to130V6,130U6,130W6, and wirings134V1,134U1,134W1to134U5,134W5connected to outer end portions of coils130V1,130U1,130W1to130V6,130U6,130W, respectively.

Thus, V-phase coils131V1to131V6are electrically connected with one another, U-phase coils131U1to131U6are electrically connected with one another, and W-phase coils131W1to131W6are electrically connected with one another.

Here, coil wire230V6includes a neutral point terminal portion141V, coil wire230U6includes a neutral point terminal portion141U, and neutral point terminal portion141V and neutral point terminal portion141U are connected to each other through a neutral point connection wiring138. In addition, coil wire230W6includes a neutral point terminal portion141W, and neutral point terminal portion141W and neutral point terminal portion141U are connected to each other through a neutral point connection wiring137. These neutral point terminal portions141V,141U,141V as well as neutral point connection wiring137and neutral point connection wiring138constitute a neutral point140.

U-phase wiring134U5drawn out from U-phase coil131U6adjacent to W-phase coil131W6in a direction of extension of W-phase wiring134W5extends over the yoke portion of divided stator cores150V6,150W5,150U5located radially outward of V-phase coil131V6, W-phase coil131W5and U-phase coil131U5.

U-phase wiring134U5passes on a radially inward side of W-phase wiring134W5, on the radially outward side of V-phase coil131V6and W-phase coil131W5, and U-phase wiring134U5is displaced radially outward as it approaches U-phase terminal portion135U5and connected to U-phase terminal portion135U5.

In addition, V-phase wiring134V5drawn out from V-phase coil131V6adjacent to U-phase coil131U6in a direction of extension of U-phase wiring134U5extends over the yoke portion of divided stator cores150W5,150U5,150V5located radially outward of W-phase coil131W5, U-phase coil131U5, and V-phase coil131V5.

V-phase wiring134V5passes on a radially inward side of W-phase wiring134W5and U-phase wiring134U5, on the radially outward side of W-phase coil131W5, and it passes on a radially inward side of U-phase wiring134U5, on the radially outward side of U-phase coil131U5.

V-phase wiring134V5is also displaced radially outward as it approaches from the drawn-out portion from V-phase coil131V6toward V-phase terminal portion135V5and connected to V-phase terminal portion135V5. In addition, W-phase wiring134W4drawn out from W-phase coil131W5adjacent to V-phase coil131V6in a direction of extension of V-phase wiring134V5extends over the yoke portion of divided stator cores150U5,150V5,150W4located radially outward of U-phase coil131U5, V-phase coil131V5and W-phase coil131W4. W-phase wiring134W4passes on the radially inward side of U-phase wiring134U5and V-phase wiring134V5, on the radially outward side of U-phase coil131U5, and it further passes on the radially inward side of V-phase wiring134V5, on the radially outward side of V-phase coil131V5. W-phase wiring134W4is also displaced radially outward as it approaches from the position of draw-out from W-phase coil131W5toward W-phase terminal portion135W4and connected to W-phase wiring134W4. Other wirings are also disposed as in the case of W-phase wiring134W5, U-phase wiring134U5, V-phase wiring134V5, and W-phase wiring134W4above.

Thus, coils130V1,130U1,130W1to130V6,130U6,130W6provided at a distance from each other in the circumferential direction are connected to each other through wirings134V1,134U1,134W1to134V5,134U5,134W5of coil wires230V2,230U2,230W2to230V6,230U6,230W6, respectively. Namely, a connection wiring or the like for connecting coils as in the conventional rotating electric machine is not necessary and the number of parts in rotating electric machine100can be decreased.

In addition, wirings134V1,134U1,134W1to134V5,134U5,134W5are disposed such that they are displaced from one another in the radial direction of stator130and they are not layered in the direction of rotation centerline O. Therefore, the height in the direction of rotation centerline O of rotating electric machine100can be suppressed to be low.

FIG. 5is a perspective view showing details of coil wire230U5. As shown inFIG. 5, coil wire230U5includes U-phase coil131U5wound around stator teeth151U5of divided stator core150U5shown inFIG. 4, U-phase terminal portion135U5drawn out from the radially inward end portion of U-phase coil131U5over yoke portion152U5of divided stator core150U5, and U-phase wiring134U4drawn out from the radially outward end portion of U-phase coil131U5.

U-phase terminal portion135U5includes a radially extending portion182U5drawn out from an inner circumferential end portion181U5which is the radially inward end portion of U-phase coil131U5and extending radially outward of stator130from inner circumferential end portion181U5, a downwardly extending portion183U5extending downward from radially extending portion182U5toward an end surface of yoke portion152, a bottom portion184U5extending radially outward of stator130from a lower end portion of downwardly extending portion183U5, and a rising portion185U5rising in the direction of rotation centerline O from the end portion of bottom portion184U5.

Inner circumferential end portion181U5extends toward the direction of rotation centerline O and U-phase terminal portion135U5is structured by bending a portion of coil wire230U5on the end portion side relative to inner circumferential end portion181U5. By thus structuring U-phase terminal portion135U by bending the portion located on the end portion side relative to inner circumferential end portion181U5extending in the direction of rotation centerline O, the number of times of bending in forming U-phase terminal portion135U5can be decreased.

U-phase wiring134U4is formed such that it is drawn out from the radially outward end portion of U-phase coil131U5formed by winding a part of coil wire230U5around stator teeth151U5over yoke portion152U5. U-phase wiring134U4is drawn out from the end portion located radially outward of U-phase coil131U5and extending in the radial direction of stator130. Thus, the number of times of bending the end portion side of coil wire230U5for forming U-phase wiring134U4is decreased. Namely, the number of times of bending coil wire230U5can be decreased by forming U-phase terminal portion135U5by drawing it out from inner circumferential end portion181U5and by forming U-phase wiring134U4by drawing it out from the outer circumferential end portion of U-phase coil131U5, so that coil wire230U5can readily be structured.

On the tip end portion side of U-phase wiring134U4, a connection portion186U4bent in the direction of rotation centerline O and connected to U-phase terminal portion135U4of coil wire230U4adjacent in the circumferential direction is formed.

Here, an insulating coating formed on a surface of coil wire230U5and coil wire230U4is removed from a portion of the surface of rising portion185U4in contact with connection portion186U4and a portion of the surface of connection portion186U4in contact with rising portion185U4, so that these portions are electrically connected with each other. It is noted that connection portion186U4is in contact with the inner surface on the radially inward side of rising portion185U4. Rising portion185U4and connection portion186U4may be bonded to each other, for example, by soldering.

Similarly, a connection portion186U5of U-phase wiring134U5drawn out from U-phase coil131U6located opposite to the direction of extension of U-phase wiring134U4with respect to U-phase coil131U5is also connected to rising portion185U5.

Coil wire230U5has a cross-section in a square shape perpendicular to a direction of extension of coil wire230U5. U-phase coil131U5is structured by winding and layering the coil wire from a base portion of stator teeth151U5shown inFIG. 4located on yoke portion152U5side toward a tip end portion of stator teeth151U5located radially inward of stator130. Thus, as compared with a coil wire having a cross-section in a circular shape, the space factor can be improved.

The structure of coil wire230U5has been described with reference toFIG. 5, however, other coil wires230V1,230U1,230W1,230V2,230U2,230W2,230V3,230U3,230W3,230V4,230U4,230W4,230V5,230W5are also similarly structured.

FIG. 6is a perspective view showing details of coil wire230U6. As shown inFIG. 6, coil wire230U6includes U-phase coil131U6attached to stator teeth151of divided stator core150, neutral point terminal portion141U drawn out from an inner circumferential end portion181U6of U-phase coil131U6, neutral point connection wiring138extending in the circumferential direction from the end portion of neutral point terminal portion141U, and U-phase wiring134U5drawn out from the outer circumferential end portion of U-phase coil131U6.

Neutral point connection wiring137of coil wire230W6is connected to neutral point terminal portion141U, and neutral point connection wiring138is further connected to a circumferentially inward side surface of neutral point terminal portion141V. Connection portion186U5bent in the direction of rotation centerline O is formed at the tip end portion of U-phase wiring134U5, and connection portion186U5is connected to a radially inward side surface of rising portion185U5.

Neutral point terminal portion141U includes a radially extending portion182U6drawn out from the end portion of inner circumferential end portion181U6radially outward of stator130, a downwardly extending portion183U6connected to the end portion of radially extending portion182U6and extending downward to the end surface of yoke portion152, a bottom portion184U6connected to the end portion of downwardly extending portion183U6, and a rising portion185U6connected to the end portion of bottom portion184U6and rising in the direction of rotation centerline O.

Neutral point terminal portion141U opens upward so as to receive W-phase wiring134W5, and bottom portion184U6extends between the yoke portion of the divided stator core and W-phase wiring134W5.

Though coil wire230U6has been described with reference toFIG. 6, other coil wires230V6and230W6are also similarly structured.

In addition,FIG. 7is a perspective view of divided stator core150U5to which U-phase coil131U5of coil wire230U5shown inFIG. 5is attached and an insulator160U5attached to divided stator core150U5. Divided stator core150U5includes yoke portion152U5extending in the circumferential direction of stator130and stator teeth151U5projecting from yoke portion152U5toward rotor120.

Insulator160U5made of an insulating member is attached to divided stator core150U5, so that divided stator core150U5and coil wire230U5are insulated from each other. Insulator160U5includes a teeth reception portion161U5having a through hole170U5capable of receiving stator teeth151U5formed and a projection portion162U5extending from teeth reception portion161U5along the inner surface of yoke portion152U5.

In addition, insulator160U5includes yoke insulating portions163U5,164U5projecting radially outward from a circumferential surface on the radially outward side of projection portion162U5and covering the end surfaces of yoke portion152U5aligned in the direction of rotation centerline O.

InFIGS. 4 and 7, teeth reception portion161U5includes sidewall portions165U5,166U5supporting respective side surfaces of stator teeth151U5and an upper wall portion168U5and a lower wall portion167U5supporting an upper end surface and a lower end surface of stator teeth151U5respectively. A protruding portion172U5protruding upward and supporting the inner circumferential surface of U-phase coil131U5is formed at an upper end portion of upper wall portion168U5, and a protruding portion171U5protruding downward and supporting the inner circumferential surface of U-phase coil131U5is also formed on lower wall portion167U5.

Projection portion162U5supports the end surface on the radially outward side of U-phase coil131U5attached to stator teeth151U5and insulates yoke portion152U5and U-phase coil131U5from each other. Projection portion162U5includes a wiring introduction portion173U5guiding U-phase wiring134U5from U-phase coil131U5attached to teeth reception portion161toward the yoke portion152U5side and supporting U-phase wiring134U5. U-phase wiring134U5is drawn out from a wiring introduction port174U5formed in projection portion162U5over yoke insulating portion164U5.

FIG. 8is a plan view of divided stator core150U5, andFIG. 9is a rear view of divided stator core150U5from the radially outward side. As shown inFIG. 8, a fixing member200U5is formed on yoke insulating portion164U5of insulator160U5. Fixing member200U5includes a fixing portion201U5, a fixing portion202U5formed at a distance from fixing portion201U5on the radially outward side, and a fixing portion203U5formed at a distance from fixing portion202U5on the radially outward side.

FIG. 10is a plan view of U-phase coil131U5and a portion in the vicinity thereof. As shown inFIG. 10, U-phase wiring134U5and V-phase wiring134V5pass through W-phase terminal portion135W and W-phase wiring134W4is drawn out from W-phase coil131W5.

In rotating electric machine100structured as such, U-phase external terminal portion136U shown inFIG. 3is supplied with U-phase AC power and U-phase coils131U1to131U6are supplied with U-phase AC power. In addition, V-phase external terminal portion136V is supplied with V-phase AC power and V-phase coils131V1to131V6are supplied with U-phase AC power. Moreover, W-phase external terminal portion136W is supplied with W-phase AC power and W-phase coils131W1to131W6are supplied with W-phase AC power. As AC power different in phase is thus supplied to each coil, rotor120shown inFIG. 1rotates.

A method of manufacturing rotating electric machine100according to the present embodiment will be described with reference toFIGS. 11 and 12as well as to any ofFIGS. 1 to 10as appropriate.FIG. 11is a perspective view showing a state in a process of manufacturing rotating electric machine100, andFIG. 12is a perspective view showing a step following the state shown inFIG. 11.

As shown inFIGS. 11 and 12, rotating electric machine100forms annular stator130such that divided stator cores150to which coils are attached are successively fitted from above in a direction opposite to the direction of extension of U-phase wiring134U, V-phase wiring134V, and W-phase wiring134W (in the present embodiment, a clockwise direction).

For example, inFIG. 11, divided stator cores150V1,150U1,150W1to150V5,150U5around which coil wires230V1,230U1,230W1to230V5,230U5are wound respectively are assembled along the circumferential direction of stator130.

FIG. 12shows such a state that divided stator core150W5into which coil wire230W5has been assembled is newly assembled from the state shown inFIG. 11.

As shown inFIG. 12, divided stator core150W5is assembled from a direction shown with an arrow A of rotating electric machine100.

W-phase wiring134W4is drawn out from W-phase coil131W5and fixed by fixing member200U5, fixing member200V5and fixing member200W5, and it passes through a recess defined by U-phase terminal portion135U5and V-phase terminal portion135V4. The tip end portion of W-phase wiring134W4is connected to the inner circumferential surface of W-phase terminal portion135W4.

Here, inFIG. 8, fixing portion201U5, fixing portion202U5and fixing portion203U5constituting fixing member200U5are formed at a distance from each other as described above, and W-phase wiring134W4can be fitted into the side surface side of fixing portion201U5from above.

Other fixing member200V5and fixing member200W5are also constituted similarly to fixing member200U5, and W-phase wiring134W4can readily be fixed by fitting divided stator core150W5in the direction of arrow A.

Moreover, the recess defined by U-phase terminal portion135U5and V-phase terminal portion135V4opens so as to be able to receive W-phase wiring134W4introduced from the direction of arrow A. Even when divided stator core150W5is inserted from the direction of arrow A, interference of W-phase wiring134W4, U-phase terminal portion135U5, and V-phase terminal portion135V4with one another is suppressed.

By positioning W-phase wiring134W5with fixing member200U5, fixing member200V5and fixing member200W5, the inner circumferential surface of W-phase terminal portion135W5and the tip end portion of W-phase wiring134W4can accurately be brought in contact with each other and connection between W-phase wiring134W4and W-phase terminal portion135W4can readily be achieved.

By thus successively attaching divided stator cores150V1,150U1,150W1to150V8,150U8,150W8, stator130can readily be formed. Thereafter, by fixing stator130in a motor case and arranging rotor120on the inner circumferential side of stator130, rotating electric machine100can be manufactured.

In the examples shown inFIGS. 11 and 12above, divided stator core150is newly inserted from the direction of arrow A in the direction opposite to the direction of extension of each wiring so as to form rotating electric machine100, however, the example is not limited as such.

FIG. 13is a perspective view showing a state in a process of manufacturing rotating electric machine100, andFIG. 14is a perspective view showing a step following the state shown inFIG. 13.

In the state shown inFIG. 13, divided stator cores150V1,150U1,150W1to which coil wires230V6,230U6,230W6are attached respectively are aligned. As shown inFIG. 14, divided stator core150W5may be inserted in a direction of an arrow B and attached in a forward direction of extension of wirings134V5,134U5,134W5.
