FIELD OF THE INVENTION The present invention relates to a motor using magneto-resistance, and more particularly to a swing type motor.

As is well known, the swing-type motor is characterized by performing a swing movement within a predetermined angle, unlike the rotor (rotator) rotates 360 degrees. As is well known, the rotation shaft 105 serving as the output shaft is press-fitted at the center of the rotor portion 103 and is installed to be rotatable inside the stator 101. Reference numeral 107 denotes a resonator (eg, a torsion spring), and the resonator 107 has a mechanical resonance frequency corresponding to the driving frequency and is connected to the rotor unit 103 to perform resonance (see FIG. 1). ). For example, when the rotor portion 103 is restored to the static equilibrium state, energy stored in the resonator portion 107 (for example, torsion spring) is used. At this time, the mechanical resonance frequency of the resonator 107, for example, the spring constant of the torsion spring and the mass moment of inertia are appropriately designed so that the resonant frequency of the system is matched to the frequency of the AC power supply (commercial power supply (50 Hz to 60 Hz)). It causes resonance motion.

On the other hand, in the stator portion 101, four stator teeth (A, B, A ', B') are formed to protrude inside the stator portion 101 (made of one body), respectively Coils are wound around the stator teeth to form stator stimuli. A pair of stator teeth A, A 'and B, B' facing diagonally are wound by the same coil (see FIG. 2). When power is alternately applied to each pair of coils from the driver (see FIG. 4), the rotor 103 performs a swing movement in the stator portion 101.

In view of the problems of the prior art, since the stator 101 has a symmetrical structure suitable for 360-degree rotation, the width and height of the stator 101 are similar, so that a lot of space is required in a product requiring a low height. Problems will arise.

)가 효율적이지가 않고 누설 자속이 많게 된다.In addition, as described above, the stator 101 is formed of a single body, and a pair of stator teeth A and A 'each rotates the stator poles (S pole and N pole) (rotation of the rotor 103). Since the structure is facing diagonally across the space), the flux path is formed relatively long in the winding excitation and thus the inductance slope (

) Is not efficient and the leakage flux is high.

The present invention has been made in such a situation, and an object thereof is to present a swing type motor implementation technology applicable to a product requiring a low height.

Furthermore, another object of the present invention is to propose a structure capable of realizing a flux path shorter than a length of a conventional flux path and reducing leakage flux in implementing a swing type motor.

Furthermore, another object of the present invention is to develop a stator and a rotor suitable for swing motion in implementing a swing type motor.

According to a preferred aspect of the present invention for achieving the above object, the present invention, in the swing type motor, the left stator is formed substantially in the right direction, the stator teeth are provided with a plurality of stator teeth are coiled on each of the stator poles A right stator block portion, which is formed substantially in a left direction, and has a plurality of stator teeth, each of which has a coil wound to become a stator pole, and a plurality of rotor teeth, and a left stator block portion and a right stator block. A rotor part installed to be rotatable between the parts, the rotor part performing swing motion as power is applied to the coil wound on the corresponding stator teeth of the left stator block part or the coil wound on the corresponding stator teeth of the right stator block part; On the coil wound around the corresponding stator teeth of the stator block. It characterized in that it comprises a drive unit for applying power and a resonator unit having a mechanical resonance frequency corresponding to the drive frequency of the drive unit and connected to the rotor unit.

The foregoing and further aspects of the present invention will become more apparent through the following embodiments. Hereinafter, the present invention will be described in detail with reference to the preferred embodiments described with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

3 is a view for explaining the structure and operation of a swing-type motor according to an embodiment of the present invention. A description with reference to the drawings described above.

As shown in Fig. 3, in the swing type motor, the present invention has a stator tooth (for example, S pole and N pole) formed in a substantially right direction and coils are wound on each of them. A stator block portion having a plurality of A's and A ''s is formed substantially in a left direction, and stator teeth (for example, B's and B's) are coiled around and become stator poles (for example, S and N poles). ') Is provided with a plurality of right stator block portion, a plurality of rotor teeth is provided and installed so as to be rotatable between the left stator block portion and the right stator block portion, the coil wound around the corresponding stator teeth of the left stator block portion Alternatively, as the power is applied to the coil wound around the corresponding stator teeth of the right stator block part, the rotor part performing the swing motion and the corresponding stator teeth of the stator block part are wound. (See Fig. 4) of power to the control coil which is the drive and further characterized in that has a mechanical resonance frequency corresponding to the driving frequency of the driving unit is configured to include a resonator unit 107 is coupled to the rotation confident.

In one embodiment, the swing type motor has been considered that only the swing angle range needs to be considered because the rotor does not rotate 360 degrees. According to an embodiment of the present invention, the stator portion is separated into two left stator block portions and a five-axis stator block portion. Accordingly, the material (for example, lamination sheet) for forming the stator portion is required to be reduced, which has the advantage of achieving cost reduction.

Specifically, the left stator block portion is formed substantially in the right direction, and a plurality of stator teeth (for example, A and A '), in which coils are wound and become stator poles (for example, S poles and N poles), is provided. Further, the right stator block portion is formed to be substantially leftward, and a plurality of stator teeth (for example, B and B '), in which coils are wound and become stator poles (for example, S poles and N poles), is provided.

In one embodiment, two separate stator parts may be physically completely separated. In addition, the two stator parts may be provided in one housing, and in some cases, may be implemented as a single member.

In one embodiment, as shown in Figure 3, the stator teeth of the left stator block portion is made of a pair (A, A '), and the stator teeth (B, B') of the right stator block portion is also made of a pair In addition, the rotor teeth provided in the rotor part are made up of two pairs, so it is possible to implement a swing-type motor which is simple but has a short flux path and high efficiency due to no leakage.

According to a characteristic aspect of the present invention, at least two stator teeth (eg, A (1), see FIG. 4), A ′ (3), among a plurality of stator teeth (eg, A, A ′) of the left stator block portion; 4) is simultaneously wound by the same coil and is energized as driving power is applied, and at least two stator teeth (e.g., B ( 2), see FIG. 4), B '(4), and FIG. 4) are wound by the same coil and simultaneously excited as driving power is applied.

)가 효율적이 되며, 누설 자속이 줄어들게 된다.That is, according to the above-mentioned characteristic configuration, it is characterized by being wound by the same coil and simultaneously excited and having at least two stator teeth A (A ') as a stator pole, both of which are provided in the left stator block portion. Similarly, it is characterized by being wound by the same coil and simultaneously excited, and having at least two stator teeth B (B ') as a stator pole, both of which are provided in the right stator block portion. Therefore, compared with the conventional, the flux path is shortened, the inductance slope (

) Becomes efficient and leakage flux is reduced.

In the above-described embodiment, since at least two stator teeth of the plurality of stator teeth provided in the left stator block portion are simultaneously excited, the flux path will be shorter if the two stator teeth are designed to be adjacent to each other. .

In one embodiment, as shown in Figure 3, a pair of stator teeth (A, A ') of the left stator block portion are each designed to be excited at the same time as the drive power is applied by being wound by the same coil, the right A pair of stator teeth B and B 'of the stator block portion can be designed to be simultaneously excited by winding by the same coil and applying driving power.

According to a characteristic aspect of the present invention, a plurality of rotor teeth provided in the rotor portion is divided into a plurality of left rotor teeth formed substantially leftward and a plurality of right rotor teeth formed substantially rightward, At least two left rotor teeth of the plurality of left rotor teeth, at least two stator teeth simultaneously excited in the left stator block part when the rotor part swings toward the left stator block part (e.g., A, A ' And at least two right rotor teeth of the plurality of right rotor teeth, which are simultaneously excited in the right stator block portion when the rotor portion swings toward the right stator block portion (B, B ').

The above configuration specifies the rotor portion more specifically, to be more suitable for the configuration of the left stator block and the right stator block. In the above, a plurality of rotor teeth provided in the rotor section are divided into left rotor teeth and right rotor teeth (as in the stator block). Further, here, it corresponds to the stator teeth provided in the angular (left / right) stator block, so as to be formed substantially leftward and rightward. According to such a configuration, many many specific advantages can be expected, and those skilled in the art can expect the height of the entire motor product to be lowered more.

In one embodiment, as shown in Figure 3, two pairs of rotor teeth provided in the rotor portion, a pair of left rotor teeth formed substantially leftward and a pair of right turns formed substantially rightward A pair of stator teeth that are implemented to be divided into electronic teeth and that the pair of left rotor teeth provided in the rotor part are simultaneously excited in the left stator block part when the rotor part swings toward the left stator block part (A A '), and the pair of right rotor teeth provided in the rotor part is a pair of stator teeth simultaneously excited in the right stator block part when the rotor part swings toward the right stator block part. It can be implemented to align with (B, B ').

According to a characteristic aspect of the present invention, at least two left rotor teeth of the plurality of left rotor teeth provided in the rotor portion are at least two stator teeth A and A 'simultaneously excited at the left stator block portion. When a plurality of right rotor teeth provided in the rotor part are not aligned with the plurality of stator teeth B and B 'provided in the right stator block part, the plurality of right rotors provided in the rotor part are aligned. In the case where at least two right rotor teeth of the electronic teeth are aligned with at least two stator teeth B and B 'which are simultaneously excited in the right stator block portion, a plurality of left rotor teeth provided in the rotor portion is left. It is characterized in that it is not aligned with a plurality of stator teeth (A, A ') provided in the stator block portion.

The above configuration specifies the rotor portion more specifically, to be more suitable for the configuration of the left stator block and the right stator block. Characterized above, when the left rotor teeth of the rotor part are aligned with the left stator teeth of the left stator block part, the left stator is implemented such that the right rotor teeth of the rotor part are not aligned with the right stator teeth of the right stator block part. Between the block portion and the right stator block portion, the rotor portion is to enable the swing operation.

In the embodiment of Figure 3, the pair of rotor teeth provided in the rotor portion is made of an asymmetrical structure, the left stator block portion and the right stator block portion is implemented to have a symmetrical structure. That is, as shown in FIG. 3, the structure of the rotor teeth of the rotor part is symmetrical based on the left / right side (in one embodiment, since the left stator block part and the right stator block part are symmetrical). Asymmetry is based on the top and bottom. As in the prior art, when the rotor block has a symmetrical structure, two pairs of rotor teeth are aligned with the stator teeth of A, A ', B, and B' at the same time, so that the rotation operation is not made (FIG. 2). Reference).

On the other hand, in the embodiment of the present invention, for example, at least two teeth of a plurality of teeth provided in the left and right stator block portion is used as a fixed stimulus. Accordingly, one or more stator poles may be provided in the stator block portion on the left and right sides. For example, the swing width may vary depending on which fixed stimulus the driving unit applies power to.

Hereinafter, the operation of the swing type motor will be briefly described with reference to FIGS. 3 and 4.

The driving unit (see FIG. 4) receives an AC power source, for example, an AC power source having a commercial frequency of 50 Hz to 60 Hz, and a pair of stator teeth A of the left stator block part in the first phase section (eg, La) of the AC power source. Apply power to the coil wound around A '). Then, as in (a), a pair of stator teeth (A, A ') of the left stator block portion is simultaneously excited to form a single phase (La), the direction in which the magnetoresistance becomes "0", that is, the right side The rotor moves to the stator block side.

When the rotor swings toward the right stator block portion, the swing angle is limited by the resonator (not shown), and the elastic repulsive force is added later when swinging in the reverse direction. (b) shows a state in which the pair of stator teeth A and A 'of the left stator block portion and the left rotor teeth of the corresponding pair of rotor portions are aligned.

Now, the driving unit applies power to the coil wound around the pair of stator teeth B and B 'of the right stator block portion in the second phase section (eg, Lb) of the AC power source. Then, as shown in (c), the pair of stator teeth B and B 'of the right stator block part are simultaneously excited to form one phase Lb, and the direction in which the magnetoresistance becomes "0", that is, the left side. The rotor moves to the stator block side.

When the rotor swings toward the left stator block portion, the swing angle is limited by the resonator (not shown), and the elastic repulsive force is added later when swinging in the reverse direction. (d) shows a state in which the pair of stator teeth B and B 'of the right stator block portion and the right rotor teeth of the corresponding pair of rotor portions are aligned.

5 and 6 are views illustrating a structure of a swing type motor according to an embodiment of the present invention. As shown, depending on how the shape of the stator portion is designed, the height of the swing motor can be determined.

As described above, according to the embodiment of the present invention, the stator part is divided into two parts, a left stator block part and a right axis stator block part. Accordingly, the material (for example, lamination sheet) for forming the stator portion is required to be reduced, which has the advantage of achieving cost reduction.

)가 효율적이 되며, 누설 자속이 줄어들게 된다.It is also characterized in that both of the stator teeth A, A '(as a fixed stimulus) are wound at the same time by the same coil and are provided at the left stator block portion. Similarly, it is characterized by being wound by the same coil and simultaneously excited, and having at least two stator teeth B (B ') as a stator pole, both of which are provided in the right stator block portion. Therefore, compared with the conventional, the flux path is shortened, the inductance slope (

) Becomes efficient and leakage flux is reduced.

In addition, since at least two stator teeth of the plurality of stator teeth provided in the left stator block portion are simultaneously excited, if the two stator teeth are designed to be adjacent to each other, the flux path is further shortened.

Further, the rotor portion is more specifically specified to be more suitable for the configuration of the left stator block and the right stator block. Characteristically, a plurality of rotor teeth provided in the rotor section divides the left rotor teeth and the right rotor teeth (as in the stator block). Further to this, it corresponds to the stator teeth provided in the angular (left / right) stator blocks, so that they are formed substantially left and right. According to such a configuration, many many specific advantages can be expected, and those skilled in the art can expect the height of the entire motor product to be lowered more.

In addition, when the left rotor teeth of the rotor part are aligned with the left stator teeth of the left stator block part, the right rotor teeth of the rotor part are not aligned with the right stator teeth of the right stator block part. Between the right stator block portions, the rotor portions enable swing motion.

In addition, for example, at least two teeth of a plurality of teeth provided in the left and right stator block portions are used as stator stimuli. Accordingly, one or more stator poles may be provided in the stator block portion on the left and right sides. For example, the swing width may vary depending on which fixed stimulus the driving unit applies power to.

Although the present invention has been described with reference to the accompanying drawings, it should not be construed as being limited thereto, but should be construed to cover many modifications that are obvious from this.
