It may be provided as a rotating power transmission unit 55, an output unit 53 that rotates by magnetic force provided by the power transmission unit 55 and transmits the rotational force to the object to be rotated.

The magnetic field forming unit 51 and the power transmission unit 55 are provided on the support unit 57 separated from the output unit 53, and the magnetic field forming unit 51 is provided by being fixed to the support unit 57, and the power transmission unit (55) is rotatably provided on the support portion (57). In addition, the power transmission unit 55 is preferably disposed to be spaced apart a predetermined distance from the circumferential surface of the magnetic field forming unit 51 along the circumferential direction of the magnetic field forming unit 51.

The support part 57 may be provided in any shape as long as the magnetic field forming part and the power transmission part can be supported, and may be omitted depending on the structure of the device in which the power supply device 5 of the present invention is provided.

The magnetic field forming unit 51 is a means for forming a rotating magnetic field through a two-phase alternating current or a three-phase alternating current.

FIG. 2 is a simplified structure of the magnetic field forming unit 51 that generates a rotating magnetic field through a three-phase AC power source and a process of generating a rotating magnetic field. Hereinafter, the magnetic field forming unit of FIG. 2 generates a rotating magnetic field with reference to FIG. First, let's look at the principle of making.

The magnetic field forming part 51 shown in FIG. 2 includes three pairs of protrusions (a first protrusion, a second protrusion, and a third protrusion).

The first protrusion is provided with a first protrusion P11 and a second protrusion P13 provided to face each other with respect to the center of the magnetic field forming unit 51, and the second protrusion is located at the center of the magnetic field forming unit 51. It is provided with a third protrusion P21 and a fourth protrusion P23 that are provided to face each other as a reference, and the third protrusion is a fifth protrusion P31 and a sixth protrusion P33 facing each other based on the center of the magnetic field forming part. ).

In addition, the first to sixth protrusions P11, P13, P21, P23, P31, and P33 are spaced apart from each other at the same distance (60 degrees).

One coil is wound in the same direction on a pair of facing protrusions (each protrusion). That is, the first coil C1 is wound on the first protrusions P11 and P13, the second coil C2 is wound on the second protrusions P21 and P23, and the third coil C3 is the third protrusion. It is wound on (P31, P33).

At this time, the winding direction of the first coil C1 is the same in the first protrusion P11 and the second protrusion P13, and the winding direction of the second coil C2 is the third protrusion P21 and the fourth protrusion. It is the same in P23), and the winding direction of the third coil C3 should be the same in the fifth protrusion P31 and the sixth protrusion P33.

In addition, each coil is coupled at a junction (N, or node).

When the three-phase AC power is supplied to each coil with a constant phase difference in the magnetic field forming unit 51 having the above-described structure, the current supplied through the first coil C1 is the largest at the time point (a). The magnetic field forming part 51 forms a magnetic field from the first protrusion P11 to the second protrusion P13.

Meanwhile, the magnetic field formed between the first protrusion P11 and the second protrusion P13 is a magnetic field from the fifth protrusion P31 to the fourth protrusion P23, and the third protrusion P21 to the sixth protrusion P33 A magnetic field directed towards

At the time point (b), since the current supplied through the third coil C3 is the largest, the magnetic field forming unit 51 forms a magnetic field from the fifth protrusion P31 to the sixth protrusion P33, and At c), since the current supplied through the second coil C2 is the largest, the magnetic field forming part 51 forms a magnetic field from the fourth protrusion P23 to the third protrusion P21.

Accordingly, it can be seen that the magnetic field rotates by 120 degrees in the clockwise direction from the time point (a) to the point point (c), and through the above-described process, the magnetic field forming unit generates a rotating magnetic field.

In the case of the magnetic field forming unit 51 shown in FIG. 1, a larger number of protrusions 515 are shown than those shown in FIG. 2, but if the magnetic field forming unit 51 has the following structure, The effect can be implemented.

The magnetic field forming part 51 (or stator) shown in FIG. 1 includes a body 511 fixed to the support 57, a plurality of protrusions 515 protruding along the circumferential surface of the body 511, and the protrusion. It includes a coil unit 517 wound around 515.

The body 511 is provided in the shape of a disc or cylinder, and the body 511 has a coupling hole 513 into which a fastening means such as a bolt is inserted, and a body through hole penetrating the center of the body 511 ( 519) may be provided.

Accordingly, the body 511 may be inserted into the coupling hole 513 and fixed to the support portion 57 by a fastening means coupled to the support portion 57.

Meanwhile, a first coil, a second coil, and a third coil are wound on the plurality of protrusions 515 provided along the circumferential surface of the body 511 in the following manner.

When any one of the protrusions is defined as the first protrusion, and the protrusion provided in a clockwise or counterclockwise direction is defined as the second protrusion and the third protrusion, the first coil is the first protrusion, the fourth protrusion, and the seventh protrusion. It is wound on the 3n-2 protrusions such as (n is 1 or more). At this time, the winding direction of the first coil wound on each protrusion should be the same.

Meanwhile, the second coil is wound on the 3n-1 protrusions such as the 2nd protrusion, the 5th protrusion, and the 8th protrusion (the winding direction of the second coil wound on each protrusion is the same), and the third coil is the 3rd protrusion. , The 6th protrusion and the 9th protrusion are wound on the 3n protrusion (the winding direction of the third coil wound on each protrusion is the same).

However, the direction in which two coils of the first coil, the second coil, and the third coil are wound on each protrusion must be provided differently from the direction in which the other coil is wound on each protrusion.

On the other hand, the output unit 53 provided in the power generating device 5 of the present invention is fixed to the output shaft 537 to which the object to be rotated (the drum of the clothing processing device or the wheel of the transport device) is coupled, and the output shaft 537 An output unit body 531 provided to surround the circumferential surface of the magnetic field forming unit body 511 and an output unit magnetic unit 533 provided on the output unit body may be provided.

The output part body 531 is a disk-shaped base 5311 to which the output shaft 57 is fixed, extends from the circumferential surface of the base 5311 toward the support part 57 and extends the circumferential surface of the magnetic field forming part body 511. It may be provided with an enclosing flange 5313.

The protruding direction of the output shaft 537 fixed to the base 5311 should be determined according to the position of the object to be rotated.

When the object to be rotated is provided in a direction opposite to the direction in which the output unit body 531 is located relative to the support unit 57, one end of the output shaft 537 is fixed to the base 5311 and the other end of the output shaft 537 is a support unit. It is provided so as to penetrate 57.

In this case, since the output shaft 537 passes through the body through hole 519 of the magnetic field forming part and is connected to the support part 57, the output shaft 537 does not interfere with the body 511 of the magnetic field forming part.

In addition, in order to rotatably support the output shaft 537, the support 57 is provided in the support through hole 571 through which the output shaft 537 passes, and a bearing that rotatably supports the output shaft 537 ( 573) is preferably provided.

On the other hand, when the object to be rotated is provided in the direction in which the output part body 531 is located, the output shaft 537 should protrude from the base 5311 toward the other side of the direction in which the support part 57 is located (see dotted line). .

However, the output shaft 537 may be provided at one end to penetrate the support part 57 (supported rotatably) and the other end to pass through the base 5311 (fixed to the base) as needed.

The output unit magnetic unit 533 may be provided as a permanent magnet fixed to the flange 5313 so as to face the magnetic field forming unit 51.

The output magnetic unit 533 is preferably provided along the inner circumferential surface of the flange 5313 so that the N pole (first pole, 5331) and the S pole (second pole, 5332) of the permanent magnet are alternately exposed. Do.

However, in the output unit magnetic unit 533, a plurality of permanent magnets are applied to the flange 5313 so that only one of the N-poles 5331 and S-poles 5332 of the permanent magnet is exposed to the power transmission unit 55. ) May be provided with a predetermined distance apart from each other along the inner circumferential surface.

Meanwhile, the output unit 53 may further include an output unit magnetic force amplification unit 535 that amplifies the magnetic force of the output unit magnetic unit 533.

As shown in FIG. 3, when a metal such as iron is placed on either side of the N-pole and S-pole of the permanent magnet, it can be confirmed through experiment that the magnetic force of the magnetic pole without the metal is increased.

That is, in the case of a bar-shaped permanent magnet, the magnetic force of each magnetic pole is 295mT and 287mT, but when a metal is placed in the S pole, the magnetic force of the N pole increases to 330mT, and the magnetic force of the S pole decreases to 97mT. can confirm.

The increase of the magnetic force of the N-pole is less than the magnetic force (381mT) that is increased when two magnets are stacked, but it can be seen that it is useful to increase the magnetic force of the N-pole provided in one magnet.

On the other hand, even in the case of a cylindrical magnet, when a metal is placed on the S pole, the magnetic force of the N pole increases from 463 mT to 500 mT, and the magnetic force of the S pole decreases from 462 mT to 245 mT.

The output unit magnetic force amplification unit 535 shown in FIG. 1 increases the magnetic force of the output unit magnetic unit 533 by using the phenomenon identified in FIG. 3.

That is, the output unit magnetic force amplification unit 535 is a means for amplifying the magnetic force of the magnetic pole exposed to the power transmission unit 55 among the magnetic poles of the output unit magnetic unit 533 fixed to the flange 5313. It may be provided in a metal (bar shape or cylindrical shape) fixed to the output unit magnetic unit 533 to support (5313).

In the present invention provided with the output unit magnetic amplification unit 535, since the output unit 53 can be configured through a permanent magnet having a small magnetic force, it is possible to reduce the manufacturing cost of the power supply device 5 as well as the rotating body. It has the effect of being able to stably rotate.

In addition, the magnetic force of the magnetic pole of the magnetic pole of the output part magnetic unit 533 that is not exposed to the power transmission part 55 (the magnetic pole of the magnetic unit fixed to the magnetic force amplification unit of the output part) is weakened. It is possible to minimize the malfunction of the electronic device of the laundry treatment device or the transportation device provided with the device 5 by a magnetic field.

Meanwhile, the power transmission unit 55 provided in the present invention is a means for transmitting the rotational power provided by the magnetic field forming unit 51 to the magnetic output unit 533.

The power transmission unit 55 is rotatably provided on the support unit 57, and a transmission unit body 551 positioned between the output unit magnetic unit 533 and the protrusion 515, and provided on the transmission unit body 551. It includes a magnetic transmission unit (555).

The transfer part body 551 may be rotatably fixed to the support part 57 through the transfer part rotation shaft 553.

1 shows as an example a case in which four power transmission units 55 (each 90 degrees apart) are rotatably provided on the support 57, but the number of power transmission units 55 is as necessary. Less than 4 or 5 or more may be provided.

The transmission unit magnetic unit 555 may be provided with a plurality of permanent magnets provided along the circumferential surface of the disk-shaped transmission unit body 551.

In this case, the transmission unit magnetic unit 555 is a circumferential surface of the transmission unit body 551 so that the N pole (first magnetic pole, 5551) and the S pole (second magnetic pole, 5552) of the permanent magnet are alternately exposed. It is preferably provided in.

However, the transmission unit magnetic unit 555 is provided with a plurality of permanent magnets spaced apart a predetermined distance along the inner circumferential surface of the transmission unit body 551, and any one of the N-pole 5551 and S-pole 5552 It may be provided to expose only the magnetic field forming part 51 (reduction of manufacturing cost).

Meanwhile, the magnetic transmission unit 555 must not only be provided so as not to come into contact with the protrusion 515 of the magnetic field forming unit, but also be provided so as not to come into contact with the rotating magnetic unit 533.

That is, the transmission unit magnetic unit 555 is preferably provided on the circumferential surface of the transmission unit body 551 so as to maintain a certain distance from the protrusion 515 and the output unit magnetic unit 533.

Further, the power transmission unit 55 may further include a transmission unit magnetic force amplification unit 557 that amplifies the magnetic force of the transmission unit magnetic unit 555.

The transmission unit magnetic force amplification unit 557 is a means for increasing the magnetic force of the magnetic pole exposed to the magnetic field forming unit 51 among the magnetic poles of the transmission unit magnetic unit 555 fixed to the transmission unit body 551. It may be provided with a metal that is fixed to the secondary body 551 to support the magnetic transmission unit 555.

The operation process of the power supply device 5 having the above structure is as follows.

When current is supplied to the magnetic field forming unit 51, the magnetic field forming unit 51 forms a rotating magnetic field, so the transmission unit magnetic unit 555 provided in the power transmission unit 55 is a transmission unit in the process of being arranged along the rotating magnetic field. The body 551 will be rotated.

When the transmission unit magnetic unit 555 rotates together with the transmission unit body 551, the output unit magnetic unit 533 is output by an attractive force or a repulsive force provided by the transmission unit magnetic unit 555. The secondary body 531 will be rotated.

On the other hand, since the body to be rotated is coupled to the output body 531 through the output shaft 537, the power generating device 5 of the present invention can rotate the body to be rotated only by magnetic force.

Comparing the present invention with a conventional power generating device provided as a magnetic field forming unit that forms a rotating magnetic field and an output unit that transmits power to the object to be rotated by rotating by the rotating magnetic field provided by the magnetic field forming unit It has the same effect.

In the power generating device 5 of the present invention, since the rotating magnetic field reduced by the power transmission unit 55 is transmitted to the output unit 53, a larger torque can be supplied to the output unit 53 compared to the conventional power generating device. Therefore, the power generating device 5 of the present invention has the effect of minimizing the volume compared to the conventional power generating device and minimizing power loss (improving the efficiency of the power supply device).

In addition, the power generating device 5 of the present invention has the effect of reducing noise or vibration of the power generating device compared to a conventional power generating device equipped with a planetary gear. This is because, in the power supply device 5 of the present invention, power transmission between the output unit 53 and the power transmission unit 55 is achieved by a magnetic field generated by a permanent magnet.

In addition, in the power generating device 5 of the present invention, even if an excessive load or a sudden load is input to the output shaft 537, the output unit 53 is not restricted by the power transmission unit 55 (output unit magnetic unit 533). Since a slip may occur between the magnetic unit 555 and the transmission unit), it is possible to prevent the power supply device 5 from being damaged by a load.

In addition, since the power supply device 5 of the present invention can amplify the magnetic force of the permanent magnet through the magnetic amplification units 535 and 557, it is possible to reduce the size of the power supply device and reduce the manufacturing cost.
