Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Similar components are denoted by the same reference numerals, and the same description will not be repeated.
For the sake of explanation, the terms “vertical direction”, “horizontal direction”, and “front-rear direction” orthogonal to each other are used. The direction of gravity is not necessarily parallel to the vertical direction, and can be parallel to the vertical direction, the horizontal direction, the front-rear direction, or any other direction.

  The various components of the present invention do not necessarily have to be independent of each other. A plurality of components are formed as a single member, and a single component is formed of a plurality of members. It is allowed that a certain component is a part of another component, a part of a certain component overlaps a part of another component, and the like.

The description will be made assuming that the downward direction faces the downstream side in the direction of gravity. The armature 100 uses, for example, the same components as the linear motor 1 exemplified in the present embodiment, the front-rear direction is replaced with the circumferential direction, the left-right direction is the axial direction, and the up-down direction is replaced with the radial direction. Can be applied to a rotary motor by replacing it with a substantially circular rotor as viewed in the axial direction.
[Linear motor 1]
FIG. 1 is a perspective view of the linear motor 1. The linear motor 1 has one or more armatures 100 arranged in the front-rear direction and a mover 55. Between the two armatures 100, a non-magnetic spacer 14 and a magnetic body 15 are located. Which of the spacer 14 and the magnetic body 15 is provided between the armatures 100 can be determined in the same manner as a known linear motor depending on the application. Hereinafter, as illustrated in FIG. 1, the armature 100, the spacer 14, and the magnetic body 15 arranged together in the front-rear direction are collectively referred to as a stator.

  A stator positioning portion (not shown) for positioning the armature 100, the spacer 14, and the magnetic body 15 which are constituent elements of the stator can be provided. As the stator positioning portion, for example, holes 16 are provided in the front-rear direction of the armature 100, the spacer 14, and the magnetic body 15 arranged in the front-rear direction, and an insertion portion such as a bolt that can be inserted into the hole 16 is employed. it can. Thereby, since each member which comprises a stator beforehand can be fixed easily, it becomes easy to fix the space | interval of armatures 100, even if the connection member 40 mentioned later is not at hand.

  Note that another armature 100 may be opposed to each armature 100 in the vertical direction via the mover 55. In this case, the two armatures 100 facing each other can be arranged substantially symmetrically in the vertical direction with the movable element 55 as the center.

  The mover 55 has one or more flat permanent magnets 5. The permanent magnets 5 are magnetized in the vertical direction, for example, and are arranged so that the magnetization directions are alternately reversed.

[Armature 100]
FIG. 2 is a perspective view of the armature 100, and FIG. 3 is an exploded view of the armature 100. The armature 100 includes a core 10, a winding 20, a coil insulating part 30, and a terminal attachment part 60.

[Core 10]
The core 10 is a magnetic body and includes magnetic pole teeth 11, a back portion 12, and two iron cores 13.
The end face of the magnetic pole tooth 11 can be made substantially perpendicular to the up-down direction, and is opposed to the mover 55 through a gap.
The back portion 12 is an end face of the core 10 and is located on the opposite side of the mover 55 with the magnetic pole teeth 11 interposed therebetween.
The iron core 13 is located outside the ring of the annular winding 20. In this embodiment, the iron core 13 is located on the outer side in the left-right direction with respect to the magnetic pole teeth 11 and extends in the up-down direction. The end of the iron core 13 protrudes in the vertical direction from the end face of the magnetic pole teeth 11. For this reason, when arrange | positioning one armature 100 to an up-down direction, the space | gap which arrange | positions the needle | mover 55 is securable by making each of the iron core 13 contact a floor surface, for example. Further, when two armatures 100 are opposed to each other in the vertical direction, alignment can be performed by bringing the iron cores 13 of the two armatures 100 into contact with each other.

  One of the two iron cores 13 included in one armature 100 can have a convex portion, and the other can have a concave portion that can be fitted to the convex portion. When combining the iron cores 13 of the two armatures 100, the two armatures 100 facing each other in the vertical direction can be easily aligned by fitting the convex portions and the concave portions.

  The winding 20 is formed by forming a conducting wire in an annular shape, and is wound with the magnetic pole teeth 11 and a coil insulating portion 30 described later inside the ring. The ring is substantially perpendicular to the up-down direction. The winding 20 is formed by winding a conducting wire in a ring shape a plurality of times, and the rings are stacked in the vertical direction. Ends (one end 21 and the other end 22) of the winding 20 extend toward the outside of the ring of the winding 20. In this embodiment, both the one end 21 and the other end 22 are located on the back 12 side in the up-down direction of the winding 20, and are extended to the same side in the left-right direction of the winding 20. That is, the one end 21 and the other end 22 are drawn out on the same surface side.

  By positioning the end portion of the winding 20 on the back portion 12 side in the vertical direction, when the one end 21 and the other end 22 are electrically connected to the connecting member 40 described later, the one end 21 and the end portion near the end surface of the connecting member 40 are connected. The other end 22 can be easily provided. Moreover, the one end 21 and the other end 22 can be provided in the same surface side by extending the one end 21 and the other end 22 to the same side about the left-right direction. That is, a plurality of windings 20 can be connected by providing one connection member 40 described later. The one end 21 and the other end 22 can be easily positioned by pulling out the one end 21 and the other end 22 in the left-right direction and arranging the armature 100, the spacer 14 and the magnetic body 15 in the front-rear direction. .

  The one end 21 and the other end 22 may be provided so as to be located on a diagonal line of the winding 20. For example, the one end 21 may be provided on the upper right front side and the other end 22 may be provided on the lower left rear side. In this way, when the core 10 is provided with a convex portion and a concave portion, the configuration of the armature 100 can be symmetric with respect to the upside down. That is, the armature 100 can be used as a member in which the winding direction of the winding 20 is the same regardless of whether it is an upper member or a lower member of the stator. That is, the armature 100 can be effectively modularized.

[Coil insulation part 30 and terminal attachment part 60]
FIG. 4 is a perspective view of the coil insulating portion 30 and the terminal mounting portion 60.
The coil insulating portion 30 is attached around the magnetic pole teeth 11 and has openings on one side or both sides in the vertical direction. That is, the coil insulating portion 30 covers the periphery of the magnetic pole teeth 11 in the front-rear direction and the left-right direction, and is located between the magnetic pole teeth 11 and the windings 20. The coil insulating part 30 can suppress the winding 20 from coming into contact with the magnetic pole teeth 11 and short-circuiting. In addition, if the coil insulation part 30 and the terminal attachment part 60 are integrally formed, the attachment property with respect to the core 10 of both can be improved.

The terminal mounting portion 60 includes two fixed portions 61 that are separated in the left-right direction, an upright portion 65 that extends in the vertical direction with respect to the fixed portion 61, and a connecting portion that connects the two fixed portions 61 via the upright portions 65. 64 and a terminal 69. The terminal attachment part 60 can be made into a set by fixing two arranged in the front-rear direction to one coil insulating part 30.
By attaching the one end 21 and the other end 22 of the drawn winding 20 to the terminal 69 in advance, the end of the winding 20 can be positioned in advance for each armature 100 even when the connecting member 40 is not at hand. The workability of attaching to the connection member 40 can be improved.
The terminal 69 can be freely attached to the terminal attachment portion 60. Thereby, the attachment workability | operativity of the edge part of the coil | winding 20 to the terminal 69 can be improved.

The fixing portion 61 which is an example of the movement suppressing portion can suppress relative movement with respect to the core 10 such as dropping of the terminal mounting portion 60 from the core 10. The fixing portion 61 is attached to the back portion 12 of the core 10 or the spacer 14 or the magnetic body 15 adjacent to the core 10 in the front-rear direction, thereby suppressing the relative movement of the core 10 and the terminal attachment portion 60. The fixing portion 61 of this embodiment is in contact with the spacer 14 or the magnetic body 15 and suppresses relative movement by friction. More specifically, for example, a structure that is locked by a claw can be employed. When a structure that engages with the terminal mounting portion 60 by frictional force or the like is employed as the fixing portion 61, the terminal mounting portion 60 can move in one side in the vertical direction or in the front-back direction with respect to the core 10. For this reason, even if the core 10 vibrates, it can suppress that the coil insulation part 30 around which the coil | winding 20 was wound does not shift | deviate or fall, but it contacts with the needle | mover 55 and is damaged.
A recess may be provided on the end face in the left-right direction of the core 10, the spacer 14, or the magnetic body 15, and the fixing portion 61 may be locked to the recess.

  Note that, by fixing or integrally forming the coil insulating portion 30 to the terminal mounting portion 60, the coil insulating portion 30 can be effectively prevented from falling off. In the present embodiment, the coil insulating portion 30 is formed integrally with the terminal mounting portion 60.

  The connecting portion 64 extending in the left-right direction passes between the end face of the magnetic pole teeth 11 and the mover 55 in the up-down direction. If the end of the coil insulating part 30 in the vertical direction is fixed to the connecting part 64, the coil insulating part 30 and the terminal attaching part 60 can be easily attached.

  The terminal 69 has a conductive winding connection 62 and a connector 63. The terminal 69 is positioned so as to be attachable to the outside in the left-right direction of the upright portion 65 located in the front-rear direction of the iron core 13. By providing the upright portion 65 on the outer side in the left-right direction, the terminal 69 can be easily attached to the connection member 40 described later. In addition, by positioning the upright portion 65 in the front-rear direction of the iron core 13, it is possible to effectively use the space and suppress the left-right dimension of the armature 100.

  The end of the winding 20 can be positioned by fixing the winding connecting portion 62 by pinching or inserting the vicinity of the end of the winding 20. By attaching the winding 20 to the winding connection portion 62, it is possible to suppress the winding 20 from being bent toward the far side of the armature 100. Further, by attaching the winding 20 to the winding connecting portion 62, the attaching operation of the winding 20 to the connector 63 can be facilitated.

  The connector 63 has a surface that can be inserted into a receptacle 41 described later. For example, by forming the surface substantially perpendicular to the front-rear direction, it is possible to tolerate a positional shift in the up-down direction. As will be described later, the connector 63 makes it easy to electrically connect or disconnect the winding 20 to the connector connecting portion 42. The winding 20 may be wound around the surface of the connector 63, or a component capable of fixing the winding 20, for example, a hole into which the winding 20 can be inserted may be provided in the surface. The connector 63 is located on the outer side in the left-right direction with respect to the winding 20. Thereby, it can suppress that the connection member 40 contacts the coil | winding 20. FIG.

  As described above, for each armature 100 of the stator, the end portions of the windings 20 can be positioned in advance by attaching the end portions of the windings 20 to the respective connectors 63, so that the mounting workability to the connection member 40 can be improved. It can be improved. Further, the distance between the armatures 100 in the front-rear direction, that is, the distance between the connectors 63 in the front-rear direction can be easily adjusted by changing the lengths of the spacers 14 and the magnetic body 15 in the front-rear direction. Similarly, the shift in the front-rear direction between the armatures 100 can be suppressed by the stator positioning portion.

  In addition, since each of the terminals 69 is provided on the opposite side of the winding 20 via the core, the attachment to the connection member 40 can be easily performed. If each of the terminals 69 is provided on the same surface, the respective windings 20 can be connected by a small number of connecting members 40.

[Connection member 40]
5A is a front view of the connecting member 40, and FIG. 5B is an enlarged view of a part of the connecting member 40. FIG. The connecting member 40 includes a receptacle 41, a connector connecting portion 42, a connecting portion 43, for example, a flat plate-shaped base material 44, and a connecting wire 45. The connecting member 40 can be attached to the outside of the armature 100, for example, the outside in the left-right direction of the armature 100. In the present embodiment, the base 44 is provided on one side of the armature 100 in the left-right direction with the long side substantially parallel to the front-rear direction and the short side substantially parallel to the up-down direction. In addition, the connector connection part 42, the connection part 43, and the connection conducting wire 45 can be previously provided in the base material 44. FIG. The connector connecting part 42 and the connecting part 43 are electrically connected via a connection conducting wire 45.

[Receptacle 41, connector connecting portion 42]
The receptacle 41 has a gap along a direction (vertical direction) parallel to the surface of the connector 63, and the connector 63 is inserted into the gap to connect the connector 63 from the surface of the base material 44 on which the connection conducting wire 45 is provided. Can be projected. The protruding connector 63 or the winding 20 attached to the connector 63 comes into contact with the connector connecting portion 42 that is electrically connected to the connection conductor 45. The terminals 69, in particular the connectors 63, can be made conductive so that the attached winding 20 is electrically connected to the connection conductor 45. The connection member 40 may be configured so that the receptacle 41 is conductive and the receptacle 41 and the connector connecting portion 42 are in contact with each other.

  Like the surface of the connector 63, the gap direction of the receptacle 41 is substantially parallel to the vertical direction, so that the tolerance of the position of the terminal 69 and the vertical direction of the armature 100 when the two armatures 100 are opposed to each other in the vertical direction. Can be tolerant of tolerances in the gap length in the direction.

The receptacle 41 is located in the vicinity of the end surface of the base member 44 as viewed from the front. In this embodiment, the receptacle 41 is located in the vicinity of the long side of the end surface. The plurality of receptacles 41 are arranged along the long side of the substrate 44. One end 21 and the other end 22 of the winding 20 are pulled out from the back 12 side in the vertical direction, and the receptacle 41 is provided in the vicinity of the end surface, so that a wide area in the central side of the base material 44 can be used as a wiring space for the connection conductor 45. can do.
By attaching the connector 63 to the receptacle 41, the winding 20 can be easily guided or positioned. Thereby, the winding 20 can be easily electrically connected to the connector connecting portion 42 arranged in the vicinity of the receptacle 41. The connector connecting portion 42 can be provided in the vicinity of the center side of the base material 44 with respect to the receptacle 41, that is, in the vicinity of the vertical direction. Moreover, the workability of the connection can be improved, and the replacement work of the connection member 40 can be easily performed.

  For example, each of the armatures 100 constituting the stator is positioned by the stator positioning portion described above, and since the end of the winding 20 is attached to the connector 63, each end of the winding 20 is fixed. The part can be positioned. Accordingly, various types of connection members 40 can be manufactured in advance by designing the positional relationship of the plurality of receptacles 41 provided on the connection member 40 according to the distance between the ends of the winding 20. . In other words, the connection relationship of the winding 20 can be easily changed by replacing the connection member 40.

  A part or all of the receptacle 41 may be opened on one side in the vertical direction so that the connector 63 can protrude. Thereby, even if the connector 63 is displaced in the vertical direction due to tolerance or the like, it can be easily attached to the receptacle 41. Further, a part or all of the receptacle 41 may be closed on the upper side. In this way, the base member 44 can be supported by the connector 63.

[Contact 43]
The connecting portion 43 is located in the vicinity of the short side of the base material 44. The connecting portion 43 can be provided with a connecting wire 50 to be described later. The connecting conductor 50 can be electrically connected to, for example, a power source (not shown), another base material 44 or the linear motor 1.

[Connection wire 45]
The connecting wire 45 electrically connects two or more of the connector connecting portion 42 or the connecting portion 43. Since the winding 20 and the connecting conductor 50 are electrically connected to the connector connecting portion 42 and the connecting portion 43, the connecting conductor 45 is arranged on the base 44 according to the connection design of the winding 20 and the connecting conductor 50. Thus, the connection members 40 can be attached to each other easily and electrically. Moreover, if it replaces | exchanges for the connection member 40 from which the layout of the connection conducting wire 45 differs, the connection relationship between armatures 100 can be changed easily.

  In addition, the well-known structure which can be employ | adopted for a circuit board, such as a printed circuit board, a perforated board | substrate, a board | plate material, a case material, can be employ | adopted for the base material 44. The connection conductor 45 and the connection conductor 50 can employ various known configurations that can be employed as a conductor, such as an etched printed copper wiring or a coated copper wire.

Moreover, it becomes easy to move the terminal attachment part 60 to the front-back direction, and position adjustment becomes easy.
The terminal mounting portion 60 has an insulating connecting portion 64 that is located on the outer side in the front-rear direction of the winding 20 and extends in the left-right direction. The connecting portion 64 serves as a so-called interphase insulating material, thereby improving the insulation in the front-rear direction of the winding 20. When the armatures 1000 are arranged in the front-rear direction, the windings of the respective armatures 1000 are provided. It can suppress that the wire | line 20 contacts and short-circuits.

In the present embodiment, since three-phase driving is performed, the connection conductors 45 are arranged so that currents of the same phase flow through the four armatures 100 each.

  The mover 55 is connected to a resonance spring 223 that is an example of an elastic body. When the electric element 230 is driven so that the movable element 55 reciprocates at a specific frequency, a resonance phenomenon occurs due to the action of the restoring force of the resonance spring 223. When the electric element 230 is driven in the vicinity of the resonance frequency, the hermetic compressor 250 can be driven with less power consumption.

  Pistons 204 are attached to both ends of the mover 55 in the front-rear direction. Therefore, the reaction at the time of compressing the working fluid in the cylinder 201a can be used for the reciprocating motion of the mover 55 as a restoring force. Further, the electromagnetic force acts between the magnetic pole 11 and the permanent magnet 5, so that the mover 55 receives a vertical force directed toward the magnetic pole teeth 11. Since the mover 55 is fixed on the central axis of the cylinder 201a into which each piston is inserted, the mover 55 is supported at both ends. For this reason, contact with the magnetic pole teeth 11 can be suppressed.

  By using the armature 100 and the connecting member 40 described above, it is possible to easily perform design according to the output and size desired by a user of a device such as a compressor.
