The trailing neighbor ϊ4Λ is the torque waveform of the current DC vibration motor of Λ, in which the period of oblique and ί :: ΐ current. As shown in the figure, when a current flows through the first and second coils, a phase difference occurs, and the torque generated when passing through the coil is determined by the size of the coil and the magnetic poles. If the spatial phase of the first and second coils is, the torque generated by the current flowing through the different coils during the period should be equivalent. ^ The symbols a to f in Fig. 4 show the positional relationship between the rotor 2 and the anchor 1 in Figs. 5A to 5F. As shown in Fig. 5a, the current directions of the first and second coils 2, 4 and 5 during the period a are the same, and since the two coils 24 and 25 are arranged on the two permanent magnets 12, they can be fully deployed. Position, therefore, both coils 24, 25 can produce the maximum torque. When the rotor 2 reaches the time point b, as shown in Fig. 5B, current continues to flow through the first coil 24 but no longer supplies the second coil 25. After that, when the period c 'of FIG. 5C is reached, the current passes through the first coil 24 only, so the rotor 2 can only be driven by the torque generated by the first coil 24.

Description of the invention (7) When the current is cut off and the current is ready to be supplied to the first record, there is basically no current passing, but: 二, two r, in other words: when two adjacent pieces of the commutator 23 are in contact, Then Christine *, when the right knife does not indicate the period e, the current will only be cut off when V is not immediately turned on. At the moment when the torsion occurs between the two coils 25 and the magnetic poles, the rotation is ready to be supplied to the first coil 24.俟 arrival time㈣, the current is at work = current 任 = ίThe way of operation, no matter the armature 22 falls at any angle, almost any time there is a current through one or more of Γ When and the second coil, according to Fleming Left-handed, is separated from the first and second coils 24, 25 and is the same: when ί is set:!; System = one; the directions in which Γ and the second coil 24, 25 are separated are opposite to each other by the magnetic force direction of / Λ, Corresponds to this load. As the motor seen in this embodiment, the current flow: = 24, 25 is only two of the three phases, the other phase, slightly 'so there is no rotation load as mentioned above. Mouth file

However, when the two coils 24 and 25 happen to hang directly above the magnetic pole 506179 — Case No. 90102103 Mu Yueri _ Xiu Wuwu, Outline of Invention "-4, the armature 22 may face in either direction Rotate so that the direction of rotation becomes less certain. In view of this, in this embodiment, the positioning pin 28 with a magnetic body is protruded in the rotation direction of the armature 22. Since the positioning pin 28 can be moved by the magnetic force of the permanent magnet 12, and the armature 22 is in a suspended position as shown in FIG. 2, a rotational torque can be obtained, and its position is equivalent to that of FIG. 4 5 State shown in Figure D. The invention is not only § but also limited to this embodiment. According to this embodiment, the first coil 24 is an outer coil and the second coil 25 is an inner coil. As shown in FIG. 6, a first coil 31 and another second coil 32 can form a double-wound coil to generate a torque equivalent to the sum of the two coils, thereby simplifying the manufacturing process. The positioning device of the positioning pin 28 is also provided in FIG. 7 with a post pin 33 slightly inclined in the direction of the magnetic force. volume of. Incidentally, the angle of the pin 33 can be an appropriate angle to obtain a certain degree of magnetic attraction without affecting the position of the static point and the driver of rotation. ^ As described in the first embodiment of the DC vibration motor of the present invention, the two coils included in the electric frame have equal spatial phases, and the armature is constructed in such a manner that current can pass through at least one of the two coils. In this way, the structure of the armature is obviously similar to that of the early coil motor, and both can improve the eccentric effect. In addition, since current can always flow through the first and second coils, smooth start-up can be performed, and no dead point exists.

_ 'Case No. 90102103 V. Description of the invention (9) A perspective exploded view, and FIG. 9 is a plan view thereof. The biggest difference between this DC vibration motor and the motor shown in Fig. 1 lies in the structure of the armature 41. The original armature 22 includes a first coil 24 (outer coil) and a second coil 25 (inner coil) coaxially wound, and the armature 41 is provided with a third coil in a tangential direction near the two coils 24 and 25. Coil (starting coil) 26 and a resin frame 42 for integrally supporting these coils 24, 25, 26 〇 Refer to Figure 10A, ...-one π-ice country u & the third coil 26 is presented Star-connected, and in the commutator 23 divided into six pieces (three groups), two pieces facing each other are connected to each other, and each piece ^ is connected to one end of the first coil 24, One end of the second coil 25 is connected to one end of the third coil 26, and the other ends of the coils form a common connection point with each other. The current system passes through two brushes 14, 15 which form a 90 ° spatial phase angle with respect to the commutator 23. The two brushes 14 and 15 rotate through the commutator Zhai 23 following the rotor 2 乂, and sequentially contact one of the first coil 24, one end of the second coil 25, and one end of the third coil 26. As a result, as shown in FIG. 10A, when the rotor 2 is rotated so that the brush 14 (or 15) is located at the junction of the two-phase Zheng piece in the commutator 23 (connected to the two pieces at the same time), > The current path is: power supply-brush 14-commutator 23-first coil and second coil 25-third coil 26-commutator 23 _ brush 15-ground_ bit. In addition, as shown in FIG. 10B, when the rotor 2 is rotated so that each of the brushes 15 and the two adjacent pieces of the commutator 23 are in contact with each other, the current path is: power supply—brush 14— Commutator 23α, second coil 25—first coil 24, commutator 23—brush 15, and ground potential. ·therefore,

Page 14: UOi / v _ Case No. 901_ V. Description of the invention (10) It is clear that the three-coil design, at the same time, contacts the commutator at 15 = 2 spinners, even if any brush 14 is short-circuited . ^ When two adjacent pieces are connected, the power supply does not occur. The operating conditions shown in Figure 11 are twisted. The operating conditions are as follows: when the current flows through the first DC vibration motor, it is the time when the power is not supplied. As shown in the figure, the difference is that the generated torque is related to the value of the dagger; the first and second coils are related to the position of the magnetic pole. The torsional force generated during this period is also approximately equal to the phase, so that the positional relationship between the rotor 2 and the stator 1 in the current table is different from that in the figure. In the corresponding period of the figure ... a ^^ # (, i a, J Λ I " 外 outer wall u ^ A) change the white device 23-the ground potential. During this period, the two coils 24, 25 averaged over the two magnets and the electric current flowing in the same direction, so the effect of torque increase was obtained. At the age of FIG. 2β, the brush 14 is located at the intersection of two adjacent pieces of the commutator 23, and the two pieces are respectively at the inner end of the second coil 25 or the third coil 26 Only when the outer end is connected to H, the current will also flow counterclockwise from the outer loop through the third coil 26, that is, the current will flow through the coils 24, 25, 26. Immediately after that, the current of the second coil 25 is immediately cut off, and enters the 12th period (: period c shown). During this period, the current only flows through the first coil 24 and the third coil 26 to provide the rotor 2 to rotate. The required torque. At the point d shown in Figure 1 2 D, Yu Jinshui was connected to the ground potential.

506179 Amendment No. 90102〗 Rib V. Description of the invention (11) The brush 15 is located on one of the commutator 23 pieces connected to the outer end of the first coil 24 and the other is connected to the inner end of the second coil 25 Next to the junction of the adjacent commutator 23 pieces, therefore, the second coil 25 starts to have current flowing again but the direction is opposite to that of the: T-turn, and then the current of the first coil 24 will be immediately passed. At this time: the first coil 24 and the second coil 25 are located on a magnet: Snow: Although the line f no longer generates torsion, then when the third coil 26 continues to the time period e in FIG. 12E, In the flute field 1 child 2 rotates again, but it can still be connected to the next one: the 'the first' coil 24 in the force starts to re-power (counterclockwise), and then the current of the second coil 26 in the Guangguang point is cut off but the first The supply of the two coils 25 is based on the structure of the DC motor described above. At any angle, the current will flow through at least two to :: electric sense flows through the three coils 24, 25, 26, according to Fleming = = will produce a turning torque. If the third coil and the coil 24, 25 are coaxial with each other and the two currents are different, the force is formed by the opposite forces of the Hankura & Green Circle 24,25 Han Dongcang. A rotating load, and, on the 12th]), the magnet is opposite, the cup in the basin initially recognizes the green ring 24, 25 is located here: the torque is not generated in the coil, so the motor-said Minato 3 and the aforementioned two equivalent coils form the position 1 of the first 2D picture. Longzhi # is enough to make the rotor 2 unfortunately stay in the mouth. The third coil 26 can also be buried first. 。Page 16 506179 ___Case No. 90102103 _Year Month B Amendment _ V. Description of the invention (12) And 'To ensure that the motor can start efficiently, the third coil 26 is compared with the first and second coils. The space phase angle is preferably kept above 1 3 5 ° as shown in Figure 9. When the rotor 2 is running, the armature 41 performs eccentric motion with respect to the rotor 2 and generates vibration by centrifugal force, and the two coils 24 and 25 are gathered together along the tangential direction of the periphery to improve its eccentricity effect. Second, this embodiment is a The three-coil motor has three coils interposed between the power sources, so even if a short circuit occurs between the segments of the commutator 23 due to the contact of the brushes 14 and 15, the power source will not cause a failure. This change mainly considers single coils If two adjacent commutator segments of the motor are in contact with each other through the brush, the two ends of the power supply have no impedance to cause a short circuit or even damage. Therefore, the distance between commutator segments in a single coil motor must be widened, but The result of this is the "dead point" problem, that is, the current cannot be conducted at a specific location. Therefore, this embodiment particularly emphasizes the three-coil motor mechanism that can completely avoid the source short circuit, and the interval between the segments of the commutator is also reduced to eliminate the "dead point" and completely eliminate the "startup benefits" or "startup failure". phenomenon. Fig. 13 is a perspective view of a third embodiment of the DC vibration motor of the present invention. As shown in the figure, the armature 51 is provided with a weight 29 on the first and second coils 24, and the first and second coils 24, and even the other] ^ 24, 25, 26 and the weight 29 All can be integrated on a resin frame 52. At the same time, in order to improve the eccentric effect, the weight of 29 pairs of coils 24, 25 ^ is better than 10 ... In order to reduce the negative rotation of magnetic force and eddy current = see, it is better to use a non-magnetic or non-conductive body for the rotor And the counterweight

Page 17 506179

In 29, the size of the first and second coils 24, which is slightly larger than the permanent magnet, is increased by 0 degrees. In particular, if the counterweight is set close to 25, the eccentric effect is more helpful. The first and second coil systems of the DC vibration motor according to the present invention are arranged in the same tangential direction around the periphery and flow through the first. Compared with the three-coil motor, the third coil obviously improves the eccentric effect during rotation. The existence of a change in the electrical phase of another coil 'and ensuring that the motor can reach the first coil, the second coil, and a third coil in the immediate vicinity at any time are still possible. In addition, it is also preferable to provide an anti-vibration countermeasure, and an application example of the present invention is mentioned. In the above embodiment, the first coil 25 is formed as an internal winding. Another example is that the circles 31 and 32 form the double-winding torque and the combined torque at the same time, so that people who are familiar with this technical field can be used in other different ways. The examples are not intended to limit the scope of their application. (2) In the second embodiment of each section of the patent scope, the armature contains a spatial phase near the third coil and the second coil, and the electrical phase of the armature will change. The armature can also use a two-coil structure. The present invention provides current to three, and also completely eliminates "dead-point" energy and starting. Moreover, the horse sample of the present invention is placed in the tangential direction of the periphery and is provided as a means for arranging the counterweight to increase the vibration increase of the vibration effect motor. It is not limited to the above-mentioned implementation 24 to form an external winding, and as shown in the second figure 14, the first and second wires ′ are used to generate a purpose equivalent to two separate processes. In terms of the basic concepts of the present invention, the embodiments of the present invention are for reference only, but any extensional changes should still be made.
