`
`Detailed Description of the Invention
`Industrial Field of Application
`
`The present invention pertains to a salient pole core coil used in motors and the like
`in which rotary force is obtained by utilizing attraction and repulsion forces relative to a
`magnet.
`Conventional Art
`for various actuating
`
`Various compact motors are used as drive sources
`mechanisms in office equipment or other electronic equipment, and can be broadly
`divided into circumferentially-opposed motors and planar-opposed motors.
`
`In a circumferentially-opposed motor, a drive magnet (rotor magnet) disposed on an
`outer rotating rotor affixed to a motor shaft is opposed to the salient portion of a yoke in an
`core affixed to a housing supporting the motor shaft, [separated] by a predetermined gap
`in the radial direction, and the outer rotating rotor is rotated by the attraction/repulsion
`forces between the magnetic field generated when the coil is energized, and the magnetic
`poles of the rotor magnet.
`
`In a planar-opposed motor, on the other hand, the surface of a disk-shaped drive
`magnet mounted on a rotary motor affixed to a motor shaft is opposed to multiple air core
`coils arrayed in a plane, rotating the rotor by the electromagnetic [inter]action with the
`drive magnet produced when the coils are energized.
`
`The present invention pertains to a structure in which a salient pole core coil is used
`in a circumferentially-opposed motor or the like, i.e., in which a coil is wound onto multiple
`arm portions formed in a radiating shape on an iron yoke.
`
`Technical Issues to be Solved by the Invention
`
`In recent years, motors comprising such salient pole core coils have been the subject
`of ever-increasing demands for reduced thickness.
`
`In conventional salient pole core coils, however, thickness was increased after
`winding the coils onto an core, and there was also variability in the thickness itself due to
`
`2
`
`Petitioners' Exhibit 1005, pg. 3
`
`

`

`inconsistent winding portions produced during winding, which required that the gap
`between the coils and rotor yokes/circuit boards (or support members) opposed to them
`on both sides be larger than necessary, limiting the ability to reduce thickness.
`
`The present invention was undertaken in light of these technical issues, and has the
`object of providing a salient pole core coil with superior reliability, suitable for reduced
`motor thickness, whereby coil thickness can be easily reduced to a uniform minimum
`thickness, work hours to address random or other misaligned windings can be reduced,
`and coil unwinding-prevention and coating protection can be securely achieved.
`
`Means for Solving Problems
`
`The present invention provides a salient pole core coil made by winding a coil onto
`the arm portion of a salient pole core , wherein the coil wound on the salient pole core is
`flattened so that the ratio of its pressed coil thickness relative to the initial coil thickness is
`≤95%; to prevent the flattened coil from uncoiling, and to [provide] coating protection, a
`constitution is adopted using molding encapsulation or adhesion by an adhesive or the like,
`whereby coil thickness can be easily [set] to a uniform minimum thickness; work hours
`spent addressing random winding or other irregular winding portions can be reduced, and
`coil unwinding can be securely prevented while providing coating protection, yielding a
`salient pole core coil with a highly reliable structure, suitable for reducing [motor] thickness.
`
`In the above constitution, by flattening the coil with the mold-closing force of the
`molding machine used for molding encapsulation, the separate manufacturing step for
`flattening can be eliminated, thereby reducing costs.
`
`Also, in the constitution above, by performing the molding encapsulation as an
`integral piece with the circuit board after assembling the salient pole core coil, coil solder
`terminals on the circuit board can be eliminated, and the coil can be securely connected to
`a circuit board without terminal work.
`
`In addition, in this constitution component count and assembly hours can be cut and
`costs greatly reduced by molding the molding encapsulation as one piece with the salient
`pole core coil mounting seat or bearing housing.
`
`Also, thermal deformation can be minimized and durability greatly improved by
`performing the molding encapsulation with a mold material having a thermal expansion
`coefficient approximately midway between that of the iron serving as core material and the
`copper serving as coil material.
`
`Embodiments
`
`Below, referring to drawings, we explain the invention in concrete detail.
`

`
`Petitioners' Exhibit 1005, pg. 4
`
`

`

`Fig. 1 is a vertical cross section showing an example of the structure of a brushless
`
`circumferentially opposing motor comprising a salient pole core coil according to a first
`embodiment of the invention; Fig. 2 is a cross section along line II-II in Fig. 1.
`
`In Figs. 1 and 2, a bearing housing 2 is joined to a support member 1, to which a
`circuit board 16 constituting a motor control circuit is affixed; a ball bearing 4 and a slip
`bearing 5 are inserted and installed in order to support a motor shaft 3 (shaft) on the
`inside diameter portion of said bearing housing 2, so that it may rotate freely.
`
`Also, a salient pole core (electro-mechanical yoke) 6 is affixed to the outer
`circumferential surface of the bearing housing 2.
`
`As shown in Fig. 2, a boss portion 7, multiple arm portions 8 (12 in the figure)
`projecting radially from said boss portion, and head portions 9 at the tip of each arm
`portion are formed on the salient pole core 6c.
`
`Coils 10 are wound on each arm portion 8 of the salient pole core 6.
`
`A salient pole core coil 11 is constituted by the salient pole core 6 and the coils 10.
`
`Note that in the illustrated example the salient pole core coil 11 is fit onto the outer
`circumference of the bearing housing 2 by the salient pole core 6 boss portion 7, and said
`bearing housing 2 and boss portion 7 are joined together to the support member 1 by
`multiple fastening screws 12, thereby affixing it.
`
`A rotor yoke 13 is affixed on the other side of the support member 1 on the motor
`shaft 3.
`
`Said rotor yoke 13 has a drum shape (or pot shape) so as to cover the outer
`circumferential surface of the salient pole core coil 11, and the center hole thereof is
`affixed by either a pressure insertion or a welding method to the motor shaft 3.
`
`A rotor magnet (drive magnet) 14 is affixed to the inside surface of the rotor yoke 13
`outer circumferential flange portion by adhesion or other means.
`
`The rotor magnet 14 faces the head portion (electrode portion) 9 of the salient pole
`core 6 in the salient pole core coil 11 across a predetermined gap.
`
`At rotor rotation positions 1-14, as shown in Fig. 2, multiple N and S poles (8 poles in
`the illustration) are magnetized.
`
`An FG magnet 15 for detecting the motor speed is affixed to the outer circumferential
`surface of the rotor yoke 13.
`
`Also, a motor drive circuit, FG pattern, coil wiring pattern and the like are formed on
`the circuit board 16 on the support member 1. The salient pole core 6 is formed, for
`example, by laminating silicon-steel plate at a thickness of approximately 0.5 mm [?unit
`illegible].
`
`In the constitution above, when a coil 10 is energized, a magnetic field is generated
`
`4
`
`Petitioners' Exhibit 1005, pg. 5
`
`

`

`in the yoke salient portions 8 and 9, and the rotor is rotated by the attraction/repulsion
`forces (magnetic force) generated between this magnetic field and the rotor magnet 14.
`
`In this case, the rotor rotation position is detected by a Hall effect element or the like
`(not shown) and, using a known current drive [method], is rotated as a brushless motor, so
`that torque is output from the motor shaft 3.
`
`In a brush motor, the same motor rotation is obtained by using brushes in place of
`the Hall elements.
`
`Figs. 3-5 are schematic partial cross sections showing an embodiment of a salient
`pole core coil 11 according to the invention.
`
`Fig. 3(A) shows the state whereby the coil 10, wound around the salient pole core 6
`arm portions in an aligned state, is placed between a movable mold 21 attached to a
`press, and a fixed mold 22; Fig. 3(B) shows the state whereby the salient pole core coil 11
`is pressed between the movable mold 21 and the fixed mold 22, mold material is injected
`between said molds 21, 22, and the coil 10 is flattened in the thickness direction and
`molding encapsulation performed.
`
`The movable mold 21 and fixed mold 22 also serve as pressurizing portions for
`pressing both sides of the coil 10.
`
`Assuming an initial thickness T for the Fig. 3(A) coil 10, then for a post-pressing
`thickness in Fig. 3(B) of t, t/T < 0.95; i.e., pressing is such that thickness is 95% or less.
`
`The coil 10 may be sufficiently flattened if allowed by the coil resistance range, but in
`general t/T is limited to approximately 0.7.
`
`For the molding material 23, a desired plastic insulating material with superior
`moldability may be used; for example, polyamide (nylon) plastics or polycarbonate, or PBT,
`AS-ABS, or other engineering plastics or the like may be used.
`
`The amount of mold material injected is set so that the coil 10 can be molding-
`encapsulated, and a thin protective layer formed on the surface thereof, but if required it is
`also possible to form a thick layer on desired surfaces.
`
`By selecting a molding material 23 with a coefficient of thermal expansion
`approximately midway between the iron serving as the core 6 material and the copper
`serving as the coil 10 material, thermal deformation caused when the motor is driven or
`due to environmental temperature differences can be minimized, and motor durability
`greatly improved.
`
`In the illustrated example, molding encapsulation of the coil 10 is performed using
`molds 21 and 22, which also serve as pressurizing portions, therefore the pressure for
`flattening said coil 10 can take advantage of the mold-closing pressure on said molds 21,
`22, so that the coil 10 flattening and molding encapsulation can be performed
`
`5
`
`Petitioners' Exhibit 1005, pg. 6
`
`

`

`simultaneously.
`
`Note that in the illustrated example we depicted the case in which the coil 10
`flattening and the molding encapsulation are conducted simultaneously, but these can
`also be conducted as separate steps.
`
`I.e. a mold or the like can be used to perform molding encapsulation only after a
`pressurizing portion attached to a press or the like is used to flatten (press) the coil 10.
`
`Coil flattening in such cases requires pressing with the outside shape held down by a
`mold [die] or the like when formed of copper only, as in air core coils, etc., but for a coil 10
`on a salient pole core coil 11 such as that above, the core 6 salient mold portion (arm
`portions 8 and head portion 9) serve as a guide, so molds such as the molding mold [die]
`described above are not necessarily required.
`
`I.e., in air core coils there are limitations on the external shape in addition to the
`thickness due to planar arraying, and for thickness, as well, there is a 100% wire factor
`limit for the wire material (70-75% for the conductor wire factor), but for the salient pole
`core coil 11, some offset is acceptable in the longitudinal direction so long as there is no
`protrusion from the yoke (salient pole core), therefore flattening can be done within the
`range allowed by coil resistance, and no particular problem occurs even with a lateral
`spread.
`
`Therefore when the operation is only to press a salient pole core coil, the winding
`space portion can be filled by the coil and the wire factor improved by adjusting the
`flattening ratio, yielding the advantage that the coil can be made significantly thinner by
`that amount.
`
`When implementing only the pressing step, the outside form of the coil must be held
`down and pressed in the case of an air core coil, so separate pressing molds [dies] must
`be prepared for each type of coil, thereby increasing the number of labor hours for the
`pressing step using a press or the like, but for the salient pole core coil, no press mold
`[die] is required, and a single pressure application is sufficient, so there is virtually no
`increase in cost.
`
`Figs. 4(A) and (B) show the state corresponding to Figs. 3(A) and (B), but in the Fig.
`4 case, what is shown is that even if a random winding portion A occurs in a part of the
`coil 10 during the winding step and is [then] flattened, pressing can achieve the same
`thickness (t) as in other parts, as shown in Fig. (B).
`
`Fig. 4 differs from the Fig. 3 case relative to the points above, but otherwise is
`substantially the same.
`
`Figs. 5(A) and (B) show the state corresponding to the above-described Figs. 3(A)
`and (B), i.e., the state in which a salient pole core coil 11 on which a coil 10 is wound is
`
`6
`
`Petitioners' Exhibit 1005, pg. 7
`
`

`

`placed between a movable mold 21 attached to a press and a fixed mold 22 prior to
`pressing, and the state in which upper and lower molds 21, 22, also serving as pressure-
`applying portions, are flattened, flattening the coil 10 from both sides and mold-
`encapsulating it with molding material 23, but Fig. 5 shows that even in cases where a
`misaligned portion B occurs at the coil 10 cross point during the winding step, and this
`portion is flattened, it can be pressed to the same thickness t as other parts.
`
`The coil winding direction changes in the region contacting the salient pole core 6
`head portion 9, but even at such cross points, as shown in the figure, a misaligned
`winding similar to the above-described random winding A [can] occur.
`
`In a conventional coil, variability in coil thickness also occurred due to misaligned
`winding at this crosspoint portion, but as shown in (B) of the same figure, the coil 10
`thickness can be formed with a uniform and minimum thickness as in other aligned
`windings simply by applying pressure in the flattening step of the present invention.
`
`Other parts of Fig. 5 have substantially the same constitution as the Fig. 3 and Fig. 4
`cases.
`
`Using the above-described embodiment, after winding the coil 10 on the salient pole
`core (yoke) 6, said coil is flattened in a planar manner from both sides, resulting in a
`flattened coil thickness ratio of ≤95% relative to the initial coil thickness, and the flattened
`coil 10 is molding-encapsulated with molding material 23, therefore in the crosspoint
`portion B the copper wire is flattened, and even in the random winding portion A the coil
`deforms filling the space, and an overall uniform and minimum thickness can be
`accurately molded.
`
`The coil 10 is molding-encapsulated at the same time or after said coil is flattened,
`so a salient pole core coil can be obtained in which unwinding of the coil 10 after pressing
`is be securely prevented, and the covering of said coil can be securely protected.
`
`It was thereby possible to obtain a salient pole core coil with superior reliability and
`suitable for reduced motor thickness, whereby coil thickness can be easily reduced to a
`uniform minimum thickness, work hours to address random or other misaligned windings
`can be reduced, and coil unwinding-prevention and coating protection can be securely
`achieved.
`
`In addition, by flattening the coil 10 with the mold-closing force of the molding
`machine used for molding encapsulation, the separate manufacturing step for flattening
`could be eliminated, thereby reducing costs.
`
`Also, as described above, by reducing the thickness of the salient pole core coil 11,
`the motor can be made thinner while at the same time the manufacturing variability in coil
`thickness can be absorbed, with the effect that manufacturing process control in motor
`
`7
`
`Petitioners' Exhibit 1005, pg. 8
`
`

`

`manufacturing is facilitated and cost reduced.
`
`Note that because of the good ductility of copper, it can be made quite thin if desired,
`but conductor resistance will rise, so that trade-off must be considered.
`
`If the salient pole core coil of the present invention is used in a brushless
`circumferentially-opposed motor, this is most effective given that there are no brushes and
`that there is a requirement for a gap between the rotor 14 and the coil 10.
`
`In the embodiment above, the two sides of the coil 10 were directly flattened, but by
`placing a thin touch-adhesion type of protective film on the pressure surface (both
`surfaces) of the coil 10 after winding, then pressing the coil 10 from over said film, said
`film can be adhered to the coil 10 surface and a covering film formed, enabling the
`simultaneous formation of an insulating protective film on the coil 10 surface.
`
`Films such as polyimide and polyester, for example, may be used for this film.
`
`It is also possible to coat a liquid or fluid plastic or the like on the pressure portion
`surface of said coil 10 after the coil 10 has been pressed; after this is then hardened and a
`coil film protective layer formed, molding encapsulation can be implemented and the same
`effect achieved as with the film above.
`
`In addition, we explained the case in which the coil 10 is molding encapsulated using
`a molding material 23, but in the present invention it is also possible, by coating or filling a
`flattened coil 10 with an adhesive or the like in place of the molding encapsulation, to
`prevent uncoiling of said coil or to implement a film protection.
`
`Various affixing agents such as epoxy or rubber may be used as the adhesive or
`filler in this case, so long as they are able to affix the coil.
`
`Coating or filling with an adhesive or the like can be done by an appropriate method
`such as brushing or immersion.
`the structure of a brushless
`
`Fig. 6
`is a vertical cross section showing
`circumferentially-opposed motor comprising a salient pole core coil according to another
`encapsulation molding of the invention.
`
`The embodiment differs in the following respects from the embodiment explained
`above with reference to Figs. 1 through 5.
`
`i) After the support member 1 is mounted on the circuit board 16, the coil 10 is
`molding-encapsulated as an integral piece with said circuit board 16 using the molding
`material 23.
`
`In this case molding encapsulation can also be performed simultaneously with the
`flattening of the coil 10, or can be performed afterward.
`
`ii) When the salient pole core coil 11 coil 10 is molding encapsulated with molding
`material 23, a part 17 corresponding to the bearing housing 2 in Fig. 2 is also
`
`8
`
`Petitioners' Exhibit 1005, pg. 9
`
`

`

`simultaneously formed with said molding material.
`
`Molding encapsulation in this case can also be performed simultaneously with the
`flattening of coil 10, or after flattening.
`
`iii) When the salient pole core coil 11 coil 10 is molding encapsulated with molding
`material 23, a coil mounting seat 18 may also be simultaneously molded of said molding
`material to fill the gap between said coil 10 and the circuit board 16.
`
`In this case molding encapsulation can be performed simultaneously with the
`flattening of the coil 10, or can be performed afterward.
`
`Each of the molding encapsulations in i)-iii) above can be independently performed,
`[or] all can be performed simultaneously as shown in the figure, or an appropriate
`selection of one or two may be implemented.
`
`As noted in i) above, if the coil 10 molding encapsulation is performed in one piece
`with the circuit board 16 after the salient pole core coil 11 is mounted to said circuit board
`by soldering or the like, then both can be affixed in a mounted state; coil solder pins on the
`circuit board 16 can thus be eliminated, and the coil 10 and the circuit board 16 can be
`securely connected without requiring terminal treatment.
`
`By simultaneously molding the part 17 corresponding to the bearing housing 2 as an
`integral piece with the coil mounting seat 18 for filling the gap between the coil 10 and
`circuit board 16 using said molding material 23 when the coil 10 is molding-encapsulated
`with the molding material 23, even adjacent constituent parts can be simultaneously
`formed as one piece, and the decrease in component count and assembly time enables a
`major cost reduction.
`
`
`Note that in the Fig. 6 embodiment, as well, by selecting a molding material such as
`plastic with a thermal expansion coefficient approximately midway between that of the
`core 6 material iron and the coil 10 material copper as the molding material 23 used for
`molding encapsulation (one-piece molding),
`thermal deformation caused by heat
`generated when driving the motor or by environmental temperature differences can be
`kept to a minimum, and motor durability can be greatly improved.
`
`Note also that in each of the embodiments above we explained cases in which the
`invention is applied to a circumferentially-opposed motor brushless motor salient pole core
`coil, but the invention may also be applied to achieve the same effect to other types of
`motors having salient pole core coils.
`
`Effect of the Invention
`
`As is clear from the explanation above, in the invention a constitution is adopted
`whereby in a salient pole core coil formed by winding a coil onto the arm portion of a
`
`9
`
`Petitioners' Exhibit 1005, pg. 10
`
`

`

`salient pole core, the coil wound on the salient pole core is flattened, such that the ratio
`between the initial coil thickness and the flattened coil thickness is 95% or below, and
`affixing by molding encapsulation or adhesive or the like is applied in order to prevent the
`flattened coil from unwinding and for coating protection; therefore a uniform and minimal
`coil thickness can easily be achieved, saving work hours needed for random or other
`irregular windings, and coil unwinding prevention and coating protection can be securely
`achieved, thereby providing a salient pole core coil with superior reliability, capable of
`reduced motor thickness.
`
`In the Claim 2 invention, in addition to the constitution above, the coil flattening is
`performed by the mold-tightening force of a molding machine for performing molding
`encapsulation, so that in addition to the effects above, the independent flattening step can
`be eliminated, thereby reducing costs.
`
`In the Claim 3 invention, in addition to the constitution above, the molding
`encapsulation is performed integrally with the circuit board after mounting the salient pole
`core coil, so that in addition to the effect above, the circuit board coil solder terminal[s] can
`be eliminated, and the coil and circuit board can be securely connected without requiring
`terminal processing.
`
`In the Claim 4 invention, in addition to the constitution above, the molding
`encapsulation is carried out [as] an integral molding with the salient pole core coil
`mounting seat or bearing housing, therefore in addition to the effects above, the number of
`parts and assembly work hours can be reduced, greatly reducing costs.
`
`In the Claim 5 invention, in addition to the constitution above, the molding
`encapsulation is carried out with a molding material having a coefficient of thermal
`expansion approximately midway between the core material and the copper coil material,
`therefore in addition to the effects above, thermal distortion can be minimized and
`durability greatly improved.
