Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 2 , the high-output bidirectional driving motor 100 according to the present invention includes: a field 110 having a winding in order to establish a magnetic field necessary for a rotation operation in a space in which a stator and a rotor are separated; an armature 120 that receives a force as current flows in the magnetic field formed by the magnetic field 110 and rotates to produce power; a commutator 140 formed on one side of the armature 120 and maintaining the direction of the current flowing in the coil 130; and supplying power in contact with the outer surface of the commutator 140, while rotating at a predetermined angle counterclockwise with respect to the direction perpendicular to the direction of the magnetic field formed by the field winding 111, to the commutator 140 It is configured to include a brush 150 that supplies power.

The basic configuration of the motor 100 is similar to that of a general motor (see FIG. 1). In general, a fixed part of an electric motor is called a stator, and a rotating part is called a rotor, and generally a stator. The rotor is on the inside on the outside.

In general, the configuration of a motor (or electric motor) in one direction has a central shaft 160 formed around the axis, and an armature 120 (armature) is formed around the axis, and the armature 120 is a winding (or armature) that operates as a main operation in a rotating electric machine. (120) winding) is accommodated. The armature 120 cuts the magnetic flux generated by the field 110 and generates torque through Fleming's left hand rule. When power is supplied to the motor (or electric motor), the motor (or electric motor) rotates, and the place where the current of the power flows is the armature 120 .

In addition, a commutator 140 receiving power is formed on one side of the armature 120 . The commutator 140 is a device for supplying the armature 120 by periodically changing the direction of the current so as to rotate in a predetermined direction in the DC or AC commutator 140 motor.

In addition, two brushes 150 formed in contact with the commutator 140 are formed. The brush 150 is a conductor serving as a contactor when connecting a stationary part (stator, etc.) with a rotor in an electric motor or a generator.

In addition, if necessary, bearings may be placed on both sides of the shaft for ease of rotation.

In addition, a field magnet 110 having a shape partially surrounding the armature 120 is formed. The field 110 is responsible for generating magnetic flux, and interacts with the armature 120 to construct a magnetic circuit. The armature 120 receives the magnetic flux created by the field 110 to obtain rotational force. Since it only needs to generate the required magnetic flux, a relatively small current flows than the armature 120 , and a permanent magnet or an electromagnet is used to create the magnetic flux. If a permanent magnet is used, magnetic flux can be created without a separate winding, but speed control can be difficult because the magnetic flux cannot be controlled.

The motor 100 configured as described above rotates when electricity is supplied to generate power. At this time, in order to rotate the motor 100 in the opposite direction, if electricity is supplied in the opposite direction during operation, the rotation continues in the rotating direction, and when electricity is supplied in the opposite direction while the motor 100 is completely stopped The motor 100 rotates in the opposite direction. In this case, rotation is possible, but sparks are generated and the life of the motor 100 is shortened.

Therefore, in the present invention, in order to solve this problem, in the conventionally used unidirectional rotating motor 100, the brush 150 supplying power to the commutator 140 changes the direction in which electricity is supplied. It becomes a possible motor 100 .

In one embodiment of the present invention, in a state in which the brush 150 supplying power to the commutator 140 is rotated at a constant angle with respect to the direction perpendicular to the magnetic field direction formed by the field winding 111, the commutator 140 ) is configured to supply electric power, and to be described in more detail, the brush 150 is rotated at a constant angle in a counterclockwise direction with respect to the direction perpendicular to the magnetic field direction formed by the field winding 111 . In this state, power is supplied to the commutator 140 .

As described above, when the brush 150 is positioned perpendicular to the direction of the magnetic field formed by the field winding 111 and power is supplied, the maximum force can be exerted when driving in the forward direction, but when driving in the reverse direction While driving with sparks without exerting force, the lifespan of the motor 100 is shortened, and eventually the motor 100 needs to be replaced. As described above, when the brush 150 is positioned perpendicular to the direction of the magnetic field formed by the field winding 111 to supply power, an imbalance in force occurs during forward and reverse driving.

In one embodiment of the present invention, the brush 150 is positioned in a direction perpendicular to the direction of the magnetic field formed by the field winding 111 to supply power, but rotates at a predetermined angle counterclockwise with respect to the vertical direction. If electric power is supplied to the commutator 140 in this state, even if the motor 100 rotates in the forward direction as well as in the reverse direction, there is no problem such as spark generation, and power is stably generated. And the power generated during forward and reverse driving is almost the same.

In one embodiment of the present invention, it is most preferable that the brush 150 is rotated counterclockwise at 11.25° to 22.5° with respect to the direction perpendicular to the direction of the magnetic field formed by the field winding 111 .

Therefore, it is possible to prevent the life span of the motor 100 from being shortened while generating sparks during reverse rotation, which is a problem that has occurred in the prior art, and it is possible to generate the same power when driving in the forward and reverse directions.

3 to 5, the high-output bidirectional driving type power clad switch 200 according to the present invention is a magnetic field 110 having a winding in order to establish a magnetic field necessary for a rotation operation in a space separated from a stator and a rotor. ) and the armature 120 that receives a force as current flows in the magnetic field formed by the magnetic field 110 and rotates to produce electric power, and is formed on one side of the armature 120 and flows in the coil 130 . The commutator 140 maintains the direction of the current, and power is supplied in contact with the outer surface of the commutator 140, and is constant in the counterclockwise direction with respect to the direction perpendicular to the direction of the magnetic field formed by the field winding 111. AC motor unit 210 for generating power by using external power, consisting of a brush 150 for supplying power to the commutator 140 in a state rotated at an angle; a gear unit 220 formed on one side of the AC motor unit 210 and decelerating the power generated in the AC motor unit 210; A winding unit 230 formed on one side of the gear unit 220 and connected to the gear unit 220 to wind up the covering of the facility house using the reduced power.

The AC motor unit 210 includes a motor 100 driven by external power, and a motor plate 211 coupled to the front surface of the motor 100 to couple the motor 100 to one side of the gear unit 220 . ) and a motor cover 212 that protects the motor 100 from external factors.

In the case of the motor 100, the description of the motor 100 described above will be substituted.

And in one embodiment of the present invention, a universal motor is used for the above driving. Compared to the conventionally commonly used AC or DC motor, it is possible to exert a large output, while its small size makes it easy to miniaturize the power clad switch 200 .

In addition, the motor plate 211 is provided with a hole fastened to the gear unit 220 and a hole fastened to the motor 100 so that the motor plate 211 is fastened to the gear unit 220 in a state where the motor plate 211 is fastened to the gear unit 220 . Only (100) can be separated. Due to this, it is easy to repair or replace the motor 100, as well as to repair or replace the gear unit 220 in a state in which the motor 100 is safely separated.

The gear unit 220 rotates in a state in which a plurality of gears are meshed with each other. The power supplied by the AC motor unit 210 is taken over and the gears rotate while decelerating or stopping the power according to a preset condition.

The gear unit 220 has an external shape that can be installed on the top of the plastic house first, and a gear body 221 having a storage space 228 for storing a plurality of gears therein, and a front surface of the gear body 221 . A front cover 222 that is installed in and blocks the front of the storage space 228 from the outside, and a rear cover 223 that is installed on the rear surface of the gear body 221 to block the rear of the storage space 228 from the outside. is composed of

Meanwhile, a partition wall 224 is formed in the gear body 221 to bisect the space in which the gear is accommodated, and one side of the space divided by the partition wall 224 transmits power from the AC motor unit 210 . It is used as a receiving unit and the other side is configured to be used as a deceleration unit that decelerates the supplied power.

And the rear cover 223 is closely coupled to the rear surface of the AC motor unit 210 (or the motor plate 211), and the gasket 240 is inserted along the circumference of the supply unit to generate rain or condensation from the outside. Prevents the gear from being corroded by penetrating into the supply part.

The gear unit 220 includes a supply gear 225 that first receives the power of the motor 100 in the gear body 221 , a reduction gear 226 for decelerating the power, and the supply gear 225 and the reduction gear 226 . ) is composed of a main gear 227 connecting the.

The supply gear 225 is installed at a position close to the motor 100 to receive power from the motor 100 .

The reduction gear 226 includes two internal gears installed on the inner periphery of the reduction part, and a plurality of helical gears 226-3 rotating along the teeth of the internal gear. The internal gear consists of a fixed internal gear 226-1 and a rotary internal gear 226-2 and is installed in the reduction unit. The fixed internal gear 226-1 is fixed to the reduction unit to induce smooth rotation of the helical gear 226-3, and the rotating internal gear 226-2 is a front surface of the fixed internal gear 226-1. It is a structure in which rotation is made together with the helical gear 226-3 in a state closely arranged to the .

As described above, it is divided into the fixed internal gear 226-1 and the rotary internal gear 226-2, and a braking shaft (not shown) for fixing the fixed internal gear 226-1 according to the user's operation situation is provided. By entering the rotary internal gear 226-2 and blocking the rotation of the rotary internal gear 226-2, it serves as a mechanical brake capable of stopping the device.

In particular, the front cover 222, which is one of the most important features claimed in the present invention, is installed on the cross section of the rotary internal gear 226-2. The front cover 222 has a shape corresponding to the inner space of the reduction unit, and when the front cover 222 is installed on the rotary internal gear 226-2, it completely shields the inner space of the reduction unit from the outside.

As the front cover 222 is installed at the forefront of the reduction gear 226 in the gear unit 220, the winding unit 230 is disassembled from the gear unit 220 for repair or replacement of the winding unit 230. Even so, it is possible to prevent separation of the reduction gear 226 by the presence of the front cover 222, and to block rain or dew condensation entering the reduction part.

Therefore, the front cover 222 makes it possible to freely separate the winding unit 230 from the gear unit 220 to facilitate repair and replacement work.

In addition, by additionally installing a support rod or roller on one side of the gear body 221, the covering material installed on the side of the facility house can also be opened and closed while moving the power covering switch 200 in the vertical direction. This is possible.
