OBJECT DESCRIPTION OF THE INVENTION (彳) The technical field to which the invention belongs (please read the note on the back and then fill out this page) The present invention relates to a brushless motor, and more particularly to a use as a vibration alarm machine for vibration generation The source is used, for example, as a small brushless motor that carries a call function of a communication device (for example, a mobile phone) or a somatosensory function of an entertainment device such as a game. Background Art Conventionally, as a technique in this field, there are Japanese Patent Publication No. 3 1 59202 and Japanese Patent Laid-Open No. 2001-232290. The weights used in the brushless vibration motor described in these publications are formed in an arc shape and are fixed to the outer peripheral portion of the rotor via welding. The weight is formed only along the outer circumference of the rotor, and the weight is welded to the rotor. However, if the curvature of the weight is irregular, when the weight is fixed to the rotor, a gap occurs between the outer peripheral portion of the rotor and the inner peripheral surface of the weight, and the weight cannot be reliably determined. Fixed at the problem point of the rotor. Especially in small rotors with a diameter of less than 10 mm, the installation work of the weight is extremely difficult. The Ministry of Economic Affairs, the Intellectual Property Bureau, the employee consumption cooperative, and the technology disclosed above, there is a Japanese real fair 3 - 1 07 55 Bulletin, but the technology is not a brushless motor. Moreover, the weight is screwed to the shaft and is not abutted against the rotor. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and in particular, it is intended to provide a brushless motor in which a weight is securely fixed to a rotor. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). -5- 1252621 A7 B7 V. INSTRUCTIONS (2) • 〇 (Please read the precautions on the back side and fill out this page) The brushless motor of the present invention is characterized in that it has a flux plate provided on the base member. 'and a circuit board provided on the flux board, and two turns provided on the circuit board, and a Hall element provided on the circuit board, and a shaft disposed between the two coils, and fixed to a disk-shaped rotor that rotates integrally with the rotor, and a magnet that is disposed on the coil and that is fixed to the rotor, and a weight support portion that is disposed on a plane portion of the rotor, and is integrally formed in the weight The support portion is a weight composed of a weight main body that bulges radially from the outer peripheral edge of the rotor. Printed by the Intellectual Property Office of the Ministry of Economic Affairs, the Consumers' Cooperatives. In this brushless motor, the power is supplied to the coil according to the electrical signal from the Hall element, and the rotor is rotated around the axis. Such a brushless motor has a weight that is used as a vibration generating source, and the weight is fixed to the rotor. The weight is not limited to a weight main body that bulges in the radial direction from the outer periphery of the rotor, but also has a weight supporting portion integrally formed with the weight main body portion. Since the weight supporting portion has a flat plate shape that abuts on the flat surface portion of the rotor, it is easy to perform welding or the like at the abutting portion. Thereby, the workability at the time of fixing the weight to the rotor is improved. In particular, in a small motor such as a diameter of less than 10 mm, the installation workability of the weight is improved. Further, in the constituent elements of the weight, the weight main body portion has a large influence on the vibration balance, and is formed with excellent precision. The weight main body portion is integrally formed with the weight supporting portion in consideration of deformation such as shrinkage during molding, and the weight main body portion is less likely to be deformed when formed. In particular, in the case where the weight main body portion has an arc shape along the outer peripheral edge of the rotor, the weight main body portion is easily deformed during molding. Thus, it can be said that the weight has the weight of the paper as described above. China National Standard (CNS) A4 Specification (21〇x297 mm) ' -6 - 1252621 A7 B7 V. INSTRUCTIONS (3) The support department is an effective countermeasure. (Please read the precautions on the back side and fill out this page.) Further, the weight main body portion is formed in an arc shape along the outer peripheral edge of the rotor, and is directed from the outer peripheral edge of the rotor toward the line side along the axial direction of the shaft. The extension is ideal. With this configuration, the weight balance of the weight can be improved while the weight of the weight can be increased. Further, it is preferable that the outer peripheral edge of the rotor is provided with an edge portion that abuts against the weight supporting portion, and the weight is supported by the rising claw of the rotor in the radial direction. According to this configuration, it is easy to position the weight on the rotor at the edge of the upright claw abutting the weight supporting portion, and the assembling workability is extremely excellent. Specially, it is a small rotor with a diameter of less than 1 mm, which makes the installation work of the weight extremely good. Further, the centrifugal force generated at the time of high-speed rotation of the rotor can cause the weight to fall off from the rotor, and the rising claw can be appropriately avoided to contribute to improvement in durability of the motor. Printed by the Ministry of Economic Affairs, the Intellectual Property Office, and the Consumer Cooperatives. It is also preferable to have a terminal that is electrically connected to the circuit board and that is partially buried in the base member, and that bulges the other portion toward the side of the base member. At this time, the power supply to the coil is controlled in accordance with an electrical signal from the Hall element, and the rotor is rotated about the axis. The terminal used in the brushless motor is electrically connected to the circuit board, and a part of the base member is buried, and the other portion is bulged toward the side of the base member. As a result of embedding a part of the terminal in the base member as compared with the case where only the mechanical support strength is secured by welding, the terminal is less unstable and becomes a stable electrical connection, and the durability is remarkably improved. Or reliability. Further, when the terminal is bulged from the side of the base member, it is easy to perform welding from the outside after soldering the terminal to a desired electrical contact of a device such as a mobile phone.

Printed 1252621 A7 _ B7 V. Invention Description (4) No good confirmation work, and it is possible to judge by welding or not. Further, the terminal is preferably provided with a terminal main body portion embedded in the base member and an elastic leg portion extending laterally from the terminal main body portion and exposed from the base member. As a result of using the elastic leg portion, the leg portion can be pushed to the electrical contact of the machine, so that the electrical joint failure of the terminal can be appropriately avoided. Further, a connecting piece is vertically provided in the terminal main body portion, and the connecting piece is inserted into the through hole provided in the circuit board, and is preferably exposed on the side of the turn. Thereby, the connection piece of the terminal can be exposed from the winding side of the circuit board, so that the electric connection work between the terminal to be soldered and the circuit board can be performed from the coil side, and the assembling workability of the motor can be improved. Further, the circuit board is a photoresist layer having wiring on the covering substrate; the coil is disposed on the photoresist layer of the circuit board, and the conductive wire is wound in a ring shape, and no photoresist is provided on the circuit board. The substrate exposed portion of the substrate on which the electric circuit substrate is exposed is formed, and the end portion of the wire exposed from the inner circumferential side of the coil is formed by the exposed portion of the substrate between the coil and the substrate. It is preferable that the inner peripheral side extends to the outer side of the turns. At this time, a circuit board having a photoresist layer covering the wiring on the substrate is provided on a flux plate provided on the base member, and a coil is disposed on the photoresist layer of the circuit board. Further, the end portion of the wire exposed from the inner peripheral side of the wire is effectively used for the space formed by the exposed portion of the substrate, and is led out to the outside, so that it is not affected by the wire under the coil. Maintain the proximity of the coil and the magnet. This is effective in improving the thinner shape of the brushless motor.

Further, it is preferable that the diameter of the wire is 0.01 m or more and 0.1 m or less. In the range of the brushless motor that can be applied to miniaturization, the diameter of the wire is 0.011 m or more and 0.1 m or less, and the wire can be selected in a realistic range. Further, the substrate exposed portion is filled with a bonding agent for bonding the coil to the circuit board, and the end portion of the wire passing through the exposed portion of the substrate is preferably fixed by an adhesive. At this time, when the wire is bonded to the circuit board, the end portion of the wire can be surely fixed by the adhesive flowing into the exposed portion of the substrate, and the breakage under the coil is less likely to occur. Further, the brushless motor of the present invention is highly versatile and can be applied to various vibration alarm devices.

An arc-shaped weight main body portion 35 that bulges from the outer peripheral edge 30b of the rotor 30 toward the radial direction of the rotor 30 is formed. The weight supporting portion 34 is fixed to the rotor 30 by two welded portions 36 using laser welding or the like in a state of abutting against the flat portion 30a of the rotor 30. Further, the two welded portions 36 are provided so as to straddle the respective rising claws 37 and the weight supporting portion 34 described below. The weight supporting portion 34 is in a state of abutting against the flat portion 30a of the rotor 30, and the abutting portion is fixed to the rotor paper by an adhesive.

In this manner, the weight 33 has not only the weight main body portion 35 that bulges from the outer peripheral edge 30b of the rotor 30 but also the weight supporting portion 34 that is integrally formed with the weight supporting portion 35. Since the weight supporting portion 34 has a flat plate shape that abuts against the flat portion 30a of the rotor 30, it is easy to apply spot welding or the like to the abutting portion, thereby fixing the weight 33 to the rotor or the like. Working variables. In particular, the mounting workability of the small diameter rotor 30 and the weight 3 3 having a diameter of less than 10 mm is improved. Further, in the constituent elements of the weight 33, the weight main body portion 35 has a large influence on the vibration balance, and is required to be formed with excellent precision. Then, shrinkage deformation at the time of sintering molding is considered, and deformation at the time of sintering molding is less likely to occur in the code body portion 35, and the weight main body portion 35 is integrally formed with the weight supporting portion 34. In particular, when the weight main body portion 35 has an arc shape along the outer peripheral edge of the rotor 30, the weight main body portion 35 is easily deformed during the sintering molding, so that the weight 33 has the weight supporting portion as described above. 34 can be said to be an effective countermeasure. Further, the weight main body portion 35 is formed in an arc shape along the outer peripheral edge 30b of the rotor, and from the outer peripheral edge 30b of the rotor 30 toward the coil 25 side along the axial direction of the shaft 20. extend. With the use of the weight main body portion 35, the weight balance of the weight 33 can be improved, and the weight of the weight 33 can be appropriately increased. Further, as shown in Figs. 3 and 5, two upright claws 37 for supporting the weight 33 in the radial direction of the rotor 30 are formed by bending at the outer peripheral edge 30b of the rotor 30. Each of the rising claws 37 abuts on an arcuate edge portion 34a of the weight supporting portion 34 that extends from the weight main body portion 35 along the outer peripheral edge 30b of the rotor 30.

It is fixed to be embedded in the base member 12 . Each of the terminals 2 1 to 24 includes a terminal body portion 40 that is embedded in the base member 1 2 and an elastic leg portion 41 that is laterally extended from the terminal body portion 40 and is bulged from the base member 1 2 . The terminal main body portion 40 of the terminals 21 and 22 is constituted by a rectangular flat plate for being reliably embedded in the base member 1 2, and the terminal main body portion 40 of the terminals 23 and 24 is for being buried in the base member 12 in order to be surely embedded. It consists of an L-shaped plate inside. In this manner, when the terminal body portion 40 of the terminals 2 1 to 24 is embedded in the base member 12 by insert molding, the terminal 2 1 to 24 is remarkably improved as compared with the case where only the mechanical strength of the support is secured by welding. The durability or 'reliability of the body. Further, when the terminals 2 1 to 24 are bulged from the side of the base member 1 2, it is easy to perform welding from the outside after soldering the terminals 2 1 to 24 to desired electrical contacts of a device such as a mobile phone. Good confirmation of the job. As a result, it is possible to judge the goodness of the welding by the appearance of the eye or the appearance of the camera, etc., which contributes to the improvement of the productivity of the brushless motor 10. Further, in each of the terminals 21 to 24, the elastic leg portion 41 is bent in a stepwise manner to form a contraction elastic.

Invention description (11) Through the circuit board 1 6, and the protrusions are caulked, On the other hand, in a state where the circuit board 16 is fixed to the base member 12, the connecting pieces 43 of the terminals 21 and 22 are exposed from the side of the coil 25 of the circuit board 16, and the connecting pieces 43 are electrically electrically connected via the solder 43. It is connected to a predetermined circuit portion of the circuit board 16. As a result, the electrical bonding work between the terminals 21 and 22 and the circuit board 16 can be performed from the side of the coil 25, so that the assembling workability of the brushless motor 10 is remarkably improved. Further, as shown in Fig. 8, the circuit board 16 has a substrate 50 formed of a fiber-reinforced plastic (for example, FRP or the like). Further, the printed wiring 52 is applied to the substrate 50 by a copper foil. The printed wiring 52 is covered by the photoresist layer 54 that prevents the printed wiring 52 from being short-circuited with the turns 25 on the circuit board 16. Further, on the photoresist layer 54, a printing portion 56 in which characters or marks are formed by screen printing is formed in the mounting region of the coil 25 (in the field of mounting the wire). The insulation of the coil 25 mounted on the circuit board 16 and the printed wiring 52 is made more reliable by the insulating portion 56. Further, a substrate exposed portion 62 is formed on the circuit board 16. In the substrate exposed portion 62, the printed wiring 52, the photoresist layer 54, and the printed portion 56 are not laminated on the substrate 50, and the substrate 50 is exposed. The base exposed portion 62 is formed by cutting off a part of the printed portion 56, and is connected to the inner peripheral side and the outer peripheral side of the annular coil mounting region. Therefore, as shown in Fig. 9, the coil 25 is mounted on the circuit board 16 as shown in Fig. 9, and the substrate exposed portion 62' located under the coil 25 has a space through which the coil 25 can pass. Further, the height of the gap between the coil 25 and the substrate 50 is, for example, about 0.1 m. Further, the substrate exposed portion 6 2 is formed at the time of printing and molding of the circuit board 16.

INSTRUCTIONS (12) (Please read the precautions on the back and fill in this page) 'The four terminals 64 that are turned on are formed at the outer periphery of the outer circumference of the coil 25. The terminals 64 are electrically connected to the wire end portion (outer peripheral side wire end portion) 66 of the outer circumferential side of the coil 25 and the wire end portion (inner peripheral side wire end portion) 68 on the inner peripheral side via a welding nip. The two terminals 64 connected to the inner peripheral side wire end portions 68 are electrically connected by the terminal connecting portions 70 formed by soldering or welding. Further, the two terminals 64 connected to the outer peripheral side wire end portions 66 are electrically connected to a power source such as an electric device, whereby electric power is supplied to both of the turns 25 via the terminals 64. The inner peripheral side wire end portion 68 of the coil 25 is exposed from the inner peripheral surface 25a of the coil, and the inner peripheral side wire end portion 68 must be connected to the terminal 64 located outside the coil 25. The inner peripheral side wire end portion 68 of the turn 25 is guided to the above-described base exposed portion 62, and is guided from the inner peripheral side of the turn 25 to the terminal 64 outside the turn 25 . Hereinafter, the state of the inner peripheral side wire end portion 68 of the substrate exposed portion 62 will be described in detail with reference to Fig. 9. Printed by the Intellectual Property Office of the Ministry of Economic Affairs, the Consumer Cooperatives As shown in Fig. 9, the wire 25 and the circuit board 16 are bonded via the adhesive 72. Further, the adhesive 72 interposed between the coil 25 and the circuit board 16 is also interposed in the gap between the substrate exposed portions 62. The inner peripheral side wire end portion 68 having a diameter of about 7 mm is extended by the inner peripheral side of the coil 25 to the coil 25 along the base material 50 in the base exposed portion 6 2 of the ytterbatch adhesive 7 2 . The outside. As described above, the inner peripheral side wire end portion 68 is fixed to the circuit board 16 by the adhesive 72, and thus is fixed to the lower side of the coil 25. Further, the wire diameter of the coil 25, that is, the diameter of the inner peripheral side wire end portion 68 is about 0.07 mm, and is about the same as the gap height of the substrate exposed portion 62. Therefore, the coil 25 mounted on the circuit board 16 is applicable to the Chinese National Standard (CNS) A4 specification (210×297 mm) at the scale of the base paper. -16-1252621 A7 B7 5. Inventive Note (13 The output portion 62 is also not arranged to float and is disposed approximately parallel to the circuit board 16. In this way, the inner peripheral side wire end portion 68 of the coil 25 is led out to the outside of the coil 25 via the base material exposed portion 62, and the inner peripheral side wire of the wire 25 can be appropriately connected while preventing the partial floating of the coil 25. End 68 and terminal 64. Therefore, it is possible to avoid the inclination of the coil 25 caused by the unprepared floating of the coil 25, so that the coil 25 and the magnet 3 1 can be accessed to facilitate the gap P between the magnet 31 and the coil 25. The brushless motor 10 of less than 0.5 mm is thinned. Further, the diameter of the inner peripheral side wire end portion 68 and the height of the base material exposed portion 62 are not necessarily the same, and the base exposed portion 62 may be slightly formed. At this time, the floating of the turns 25 can also be suppressed. Further, the wire diameter of the turns 25 including the outer peripheral side wire end portion 66 of the coil 25 and the inner peripheral side wire end portion 68 may be in the range of 0.01 mm or more and 0.1 mm or less. That is, a wire having a diameter of less than 0.0 1 mm is difficult to fabricate with a small brushless motor. Further, when a wire having a diameter of more than 0.1 mm is applied to the brushless motor 10, the wire rim formed by the wire material becomes large, and accordingly, the brushless motor 10 is enlarged, and the brushless motor is improved. 1 The size of the crucible is less than ideal. Hereinafter, a fan motor having the same configuration as that of the brushless motor 1 described above will be described with reference to the first drawing. The same or equivalent elements as those of the brushless motor 1 are denoted by the same reference numerals, and the description thereof will not be repeated. As shown in Fig. 1, the configuration of the brushless fan motor 80 and the frame 8 2 is different from the configuration of the casing 19 of the brushless motor 10.

Invention description (14) (Please read the note on the back and fill in this page) Also, fan motor 80 is replaced by weight 33 A plurality of (e.g., five) blades 88 are fixed at the rotor 30 and are different from the brushless motor 10 required to generate vibration. The vane 88 is fixed to the rotor 3 or the shaft 2 〇 while bulging radially from the outer circumference of the rotor 30 or the shaft 20. Further, each of the blades is 8 8 疋; and the rotor 30 is rotated to be a body. Further, in the lid body 86, an air introduction hole 86a is formed at a position corresponding to the blade 88. Therefore, when the vane 88 is rotated integrally with the rotor 30, air is forcibly introduced into the fan and the motor 80 through the air introduction hole 86a. Further, on the lower surface of the base member 804, an air discharge hole 854a is formed corresponding to the position of the portion where the blade 8 is bulged. Thus, when the vane 8 is rotated integrally with the rotor 30, air is forcibly discharged from the fan motor s through the air discharge hole 8 4 a. In the case of the fan motor 80, the base unit exposed portion 6 2 is formed on the circuit board 16 (see Fig. 9). Therefore, the inner peripheral side wire end portion 68 of the coil 25 is led out to the outer side of the coil 25 via the substrate exposed portion 6 2, whereby the body of the wire 圏 25 does not float at the inner peripheral side wire end portion 68. The inner peripheral side wire end portion 68 of the coil 2 5 and the terminal 64 can be connected. In this way, the thickness of the fan motor 80 can be reduced. The above describes the embodiment of the brushless motor of the present invention, and various vibration alarm devices capable of mounting the brushless motor 10 will be described below. As shown in Fig. ii, the internal substrate 1 定1 of various electronic components is housed inside the mobile phone 1 of the first example of the vibration alarm device, and the internal substrate 1 〇1 is mounted thereon.
