Definitions

  • the present invention concerns solutions for winding coils of wire onto dynamo-electric machine components.
  • the present invention concerns forming wire coils by simultaneously winding a plurality of wires onto the dynamo-electric machine component.
  • wire coils may be wound onto the poles of a lamination core or may be wound onto themselves in components that do not require or possess poles.
  • wire coils have the purpose of generating the electromagnetic field needed in the final application of the dynamo-electric machine component.
  • the previously mentioned lamination core may be either a stator core or an armature core of a dynamo-electric machine.
  • the dynamo-electric machine as a whole may be an electric motor, which is used for many types of driving applications.
  • the turns of the wire coil must be regularly disposed (e.g., along the sides of the pole pieces) without twisting the plurality of wires onto each other. Further, the wires must be placed so that the wire turns are positioned in an ascending or descending layer formation (commonly referred to in the art and hereinafter as “stratification”).
  • the present invention proposes to perform multiple-wire winding processes that avoid wire twisting and improper disposition of the wires. Further, the present invention proposes to improve the ability of the wire dispensing member to traverse the spacings on the dynamo-electric machine component. As a consequence, the winding processes performed with the present invention are less likely to be hindered by interference and are capable of obtaining more wire fill within the component spacings and higher winding speeds.
  • FIG. 1 is an elevational partial view of a wound stator core as seen from an axial end thereof;
  • FIG. 2 is a partial sectional view of the stator core showing certain parts of the apparatus of the present invention as seen from direction 2 of FIG. 1;
  • FIG. 3 is a partial sectional view of the apparatus taken from line 3 - 3 of FIG. 2;
  • FIG. 4 is a partial sectional view similar to FIG. 3 that shows the apparatus of the present invention disposed to the left of the apparatus shown in FIG. 3;
  • FIG. 5 is a schematic view showing the overall apparatus of the invention as seen from view lines 5 - 5 of FIG. 2.
  • stator core 10 has hollow cylindrical interior 11 centered on longitudinal axis 12 . Interior 11 is delimited externally by pole pieces 13 , which stem from annular portion 14 of the stator core. Expansions 13 ′ of pole pieces 13 are usually the innermost portions of stator core 10 and delimit the spacing of interior 11 . Gaps 16 existing between adjacent expansions 13 ′ are access passages which allow communication between interior 11 and slot spacings 15 . In the case of the stator core shown, gaps 16 and slot spacings 15 are inclined by a predetermined angle with respect to central axis 12 .
  • the embodiment which is illustrated in the present application is directed toward the simultaneous winding of three wires around the poles of a stator core.
  • any number of wires may be simultaneously wound in accordance with the present invention.
  • the present invention may be used to wind a wire coil through multiple poles.
  • the present invention may be used to wind wire coils around virtual poles in which no physical pole exists on the stator core.
  • wire coils are wound around each other about a theoretical pole axis on the stator. This type of stator may allow even more wire coils to be placed within a set amount of space in the core and are fully contemplated by the present invention.
  • wire nozzle 20 is shown in various relative consecutive positions P 1 -P 8 , which the wire nozzle occupy when moving around pole piece 13 to simultaneously dispense wires W 1 , W 2 , and W 3 . More particularly, by relative movements of wire nozzle 20 around pole piece 13 , wires W 1 , W 2 , and W 3 are simultaneously dispensed from respective wire exits 21 , 22 , and 23 of wire nozzle 20 to become tensioned against pole piece 13 .
  • Positioning of wire nozzle 20 in positions P 1 -P 8 can be achieved by relative movements between stator core 10 and wire nozzle 20 .
  • stator core 10 and wire nozzle 20 can be rotated with relative rotation R 1 when wire nozzle 20 is beyond end 10 ′ of stator core 10 .
  • relative rotation R 2 may be provided when wire nozzle 20 is beyond end 10 ′′ of stator core 10 .
  • Rotations R 1 and R 2 are both substantially about central axis 12 of stator core 10 .
  • stator core 10 and wire nozzle 20 may be relatively translated in directions T 1 and T 2 , which are substantially parallel to central axis 12 of stator core 10 .
  • FIG. 2 does not show the various positions of the stator core 10 as it is moved with relation to a stationary wire nozzle 20 . Instead, FIG. 2 shows the positions of wire nozzle 20 in the first plane (the plane of FIG. 2) as it accomplishes relative translations T 1 and T 2 and relative rotations R 1 and R 2 while stator core 10 is stationary.
  • rotations R 1 and R 2 and translations T 1 and T 2 are strictly relative between wire nozzle 20 and stator 10 .
  • Either nozzle 20 or stator 10 may be moved in order to accomplish this relative movement. It will also be useful in the following to define an instantaneous relative trajectory (or direction of movement) of wire nozzle 20 with respect to the relative movement between nozzle 20 and stator core 10 .
  • This instantaneous relative trajectory (or direction of movement) of wire nozzle 20 should be understood to be the instantaneous direction of movement of wire nozzle 20 , as a result of the relative movement between nozzle 20 and stator 10 , seen from a frame of reference in which stator 10 is held fixed.
  • rotations R 1 and R 2 may be sequenced and combined with translations T 1 and T 2 to accomplishes closed path 17 of wire nozzle 20 around pole piece 13 .
  • a single closed path 17 may wind one turn of wire coil C with wires W 1 , W 2 , and W 3 around pole 13 .
  • a cumulative and predetermined number of closed paths like 17 achieves winding of the number of turns required by coil C.
  • wire nozzle 20 and stator 10 is also provided with relative radial motions S 1 and S 2 , which are substantially parallel to pole piece sides 13 ′′ (and substantially perpendicular to central axis 12 ) in order to accomplish the previously described wire stratification.
  • the stratification formation requires accomplishing closed paths like 17 on a number of adjacent parallel planes that are parallel to the first plane (the plane of FIG. 2).
  • the multiple wires are dispensed on adjacent planes that are parallel to each other and which are substantially perpendicular to radii that perpendicularly emanate from central axis 12 .
  • position P 1 shows wire nozzle 20 when it is just about to start traversing a longitudinal extension of gap 16 .
  • translation T 1 is combined with rotation R 1 to accommodate the angle of incline of the longitudinal extension with respect to central axis 12 .
  • Position P 2 shows wire nozzle 20 during the previously described stroke.
  • Position P 3 shows wire nozzle 20 when the previously described stroke is just about to end.
  • Position P 4 shows wire nozzle 20 when a rotation R 1 is occurring.
  • Position P 5 shows wire nozzle 20 when rotation R 1 is about to end and an opposite stroke to traverse the opposite extension of gap 16 is just about to start.
  • Position P 6 shows wire nozzle 20 during the return stroke to traverse the opposite extension of gap 16 which includes translation T 2 and rotation R 2 .
  • Position P 7 shows wire nozzle 20 when the return stroke is just about to end.
  • Position P 8 shows wire nozzle 20 when a rotation R 2 is occurring.
  • the relative movement from P 3 to P 5 and from P 7 to P 1 may include movements in addition to rotations R 1 and R 2 , respectively.
  • translations T 1 and T 2 and stratification motions S 1 and S 2 may be programmed during those strokes to dispose wires W 1 , W 2 , and W 3 in a tensioned manner against ends 13 ′′′ of pole piece 13 .
  • the traversing strokes from position P 1 to P 3 and from position P 5 to P 7 may also be further programmed to include stratification motions S 1 and S 2 .
  • wire nozzle 20 needs to be in a particular orientation with respect to gap 16 during the traversing stroke to dispense wires W 1 , W 2 and W 3 within slot spacing 15 in a tensioned manner against the sides of pole piece 13 without twisting or overlap of the wires.
  • wire nozzle 20 must occupy a portion of gap 16 during each of the traversing strokes (see FIG. 3) so that it is partially inserted into spacing 15 .
  • portions of rotations R 1 and R 2 need to be combined with translations T 1 and T 2 so that wire nozzle 20 moves within gaps 16 without collision with the borders of expansions 13 ′.
  • wire nozzle 20 To avoid twisting wires W 1 , W 2 and W 3 during translations and rotations T 1 , T 2 , R 1 , and R 2 , wire nozzle 20 needs to be oriented differently depending on the relative position which it occupies around pole piece 13 (i.e., the position of nozzle 20 on closed path 17 ). In other words, wire nozzle 20 needs to be steered or programmably controlled during translations and rotations T 1 , T 2 , R 1 , and R 2 to appropriately orient wire exits 21 , 22 , and 23 and to reduce the necessary size of gaps 16 .
  • steering of wire nozzle 20 around axis 34 requires causing wire nozzle 20 to perform predetermined rotations R 0 around axis 34 so that wire nozzle 20 can be appropriately oriented around axis 34 as it travels on closed path 17 .
  • wire nozzle 20 is connected to the top of shaft 31 by means of flange portion 32 ′.
  • Flange portion 32 ′ is bolted to the top of shaft 31 by means of screws 32 ′′.
  • Shaft 31 is also provided with a pulley portion 33 engaged by belt 46 .
  • Shaft 31 is supported for rotation around axis 34 using support bushings 35 and 36 seated in support plates 39 and 40 , respectively.
  • Support plates 39 and 40 are distanced from each other by means of upright plate 44 .
  • Support plates 39 and 40 and upright plate 44 can be joined to form a single arm structure, as shown in FIG. 3, by means of bolts like 45 .
  • Belt 46 can circle around upright plate 44 .
  • wire nozzle 20 By driving belt 46 , wire nozzle 20 can be provided with rotation R 0 around axis 34 to achieve the appropriate orientations.
  • Shaft 31 is hollow and flared in end 31 ′ for smooth passage of wires W 1 , W 2 and W 3 .
  • Wire nozzle 20 is provided with a lower bore 35 for passage of wires W 1 , W 2 , W 3 from shaft 31 to wire nozzle 20 .
  • Lower bore 35 communicates with an enlarged hollow portion 36 of wire nozzle 20 where wires W 1 , W 2 and W 3 separate to reach their respective wire exits 21 , 22 , 23 .
  • Wire exits 21 , 22 , and 23 are on separate surfaces 21 ′, 22 ′, 23 ′ of wire nozzle 20 which may also be understood to demark separate adjacent parallel planes. Each of these adjacent parallel planes is substantially perpendicular to central axis 34 of wire nozzle 20 and substantially parallel to the first plane. In this way, wires W 1 , W 2 and W 3 can be dispensed from wire nozzle 20 along separate courses like 41 , 42 and 43 , respectively. Dispensing of the wires along these different courses is another feature for avoiding twisting of wires W 1 , W 2 , and W 3 during any relative movements of wire nozzle 20 with respect to the stator core 10 .
  • wire exits 21 , 22 , and 23 may be maintained in predetermined orientations around axis 34 as wire nozzle 20 travels along closed path 17 .
  • wire nozzle 20 is steered or programmably controlled by maintaining the orientation of an axis in the first plane that is aligned with the wire exits with respect to an instantaneous relative direction of movement of nozzle 20 .
  • the angle between this wire exit axis in the first plane and the instantaneous relative direction of movement being defined as angle A.
  • the angular orientation of the wire nozzle (around axis 34 ) and therefore the orientation of the wire exit axis is programmably controlled to vary as nozzle 20 travels along closed path 17 .
  • angle A may be constant in certain portions of the closed path (e.g., during the traversing strokes) and variable in other portions (e.g., during rotations R 1 and R 2 ).
  • the configuration of the external surface (formed by sides 13 ′′ and ends 13 ′′′) of pole piece 13 may determine the choice of angle A.
  • a circular configuration of the ends of pole piece 13 may require a variation of angle A so that the wire exit axis in the first plane containing wire exits 21 , 22 , and 23 is maintained substantially tangent to the circular configuration of the exterior contour of ends 13 ′′′.
  • wire nozzle 20 has a length and a width
  • the angular orientation of wire nozzle 20 about axis 34 is programmably controlled so as to minimalize a cross sectional area of the wire nozzle with respect to the instantaneous relative direction of movement of wire nozzle 20 (i.e., by orienting the length of wire nozzle 20 with the direction of movement).
  • the previously mentioned cross sectional area of wire nozzle 20 being taken across a plane that is substantially perpendicular to the instantaneous relative direction of movement of wire nozzle 20 in the first plane of FIG. 2.
  • Such a scheme of orienting wire nozzle 20 may be especially useful during the traversing strokes to minimize the required size of gaps 16 and reduce the likelihood of collision or interference with wires already wound within spacings 15 .
  • Such an orientation may also be understood as an alignment of the wire exit axis with the instantaneous relative direction of movement of wire nozzle 20 such that angle A is zero.
  • plates 39 and 40 are joined to appendix 50 of carriage structure 51 by means of bolts like 52 .
  • Motor unit 53 can be supported by plate 39 and fastened to it with bolts 54 .
  • Pulley wheel 55 is assembled to the output shaft of motor unit 53 .
  • Pulley wheel 55 is engaged by belt 46 so that rotation of the motor unit causes rotations RO of wire nozzle 20 around axis 34 .
  • Carriage structure 51 is provided with further appendixes 56 .
  • Each of appendixes 56 have slide portions 57 that are able to run on guides 58 .
  • Guides 58 are supported by frame structure 59 (shown partially in FIGS. 4 and 5) in order to be substantially perpendicular to the planes in which translations T 1 and T 2 are accomplished.
  • Motor unit 60 driving screw 61 (which is engaged in a threaded portion of carriage structure 51 ) is provided for causing carriage structure 51 to run along guides 58 .
  • Guides are also parallel to directions S 1 or S 2 used for the stratification motion of wire nozzle 20 .
  • plates 39 and 40 are able to run in directions S 1 or S 2 (i.e., parallel to guides 58 ) so that wire nozzle 20 can move in radial directions S 1 or S 2 to stratify wires W 1 , W 2 and W 3 along pole piece 13 .
  • wires W 1 , W 2 , and W 3 may run unimpeded to end 31 ′ of shaft 31 from a wire source and tension unit (not shown) in order to be dispensed from the exits of wire nozzle 20 .
  • Positioning of the stator core 10 with respect to wire nozzle 20 can be achieved by means of assembly 70 shown in FIG. 5. More particularly, assembly 70 holds the stator core in a predetermined position with respect to frame structure 59 .
  • Assembly 70 may be similar to the portion of apparatus shown in the previously incorporated Stratico et al. U.S. patent for rotating and indexing the stator core.
  • Motor unit 71 and rotation bar 74 of assembly 70 are used for rotating the stator core for rotations R 1 and R 2 .
  • Rotation bar 74 bears a gear (not shown), which engages an annular gear (not shown) surrounding stator core 10 so that rotation of the rotation bar 74 rotates the annular gear and consequently stator core 10 .
  • Motor unit 72 and screw 73 of assembly 70 may be used to provide stator core 10 with translations T 1 and T 2 .
  • the aforementioned gear borne by rotation bar 74 has keyways which allow the gear to translate along rotation bar 74 to remain in engagement with the aforementioned annular gear during translations T 1 and T 2 .
  • Motors units 53 , 60 , 71 and 72 may be actuated and controlled by control system 73 along signal and electric supply lines 53 ′, 60 ′, 71 ′, and 72 ′, respectively.
  • Control system 73 is configured according to the latest available techniques for controlling and programming general motions and positioning with NC axes (numerical controlled axes).
  • Sequence and regulation algorithms using externally input data may be applied by control system 73 to actuate the motor units so that translations T 1 and T 2 , rotations R 1 and R 2 , stratification motions S 1 and S 2 , and rotations RO are performed as operations which follow a sequential order, or in combination with each other. Precise synchronization between these movements may be guaranteed by control system 73 . The values of these movements may be found through practical trials which involve winding the actual wires on representative models of the pole configurations.
  • three-dimensional computer simulation of the wire nozzle and stator core motions with respect to the pole piece configuration, together with representations of the various wire extensions from the wire nozzle to the pole piece in the various instances of the motions, may be used to determine the initial values for the practical trials.
