Description

Improved low speed generator

The present invention relates to a generator, and more particularly, to a low speed generator capable of generating electricity at low speed by reducing the rotational resistance of the rotor.

A generator is a device that converts mechanical energy into electrical energy, and includes a magnet for generating a magnetic field and a conductor for generating an electromotive force such that a magnet or a conductor rotates, and a rotating field generator and a conductor in which the conductor stops and the magnetic field rotates. There is a rotating armature generator which rotates and stops the magnetic field.

Since the magnitude of the electromotive force generated by the generator is proportional to the strength of the magnetic field and the length of the conductor and the relative speed of the magnetic field and the conductor, the electromotive force is increased by increasing the strength of the magnetic field, forming the conductor long, or increasing the relative speed of the magnetic field and the conductor. In general, the relative speed of the magnetic field and the conductor is increased to increase the electromotive force.

In order to increase the relative speed of the magnetic field and the conductor, it is necessary to increase the rotational speed of the rotor. In this case, high-speed rotation is required. Therefore, when applying low-speed rotational power such as tidal power, wind power, and road power generation, the desired electromotive force cannot be obtained.

Accordingly, a low speed generator capable of obtaining a desired electromotive force using a low speed rotational power has been developed. An example of the "low speed generator" of the Utility Model Registration No. 20-0217447 is shown in FIG.

The low speed generator of FIG. 5 has a structure in which a high electromotive force is obtained at low speed rotational power by rotating the rotor 10 and the stator 20 in opposite directions, so that the fixed shaft 1 is rotatably fixed to the rotating cylinder 40. The fixed shaft 1 is provided with a rotor 10 having a commutator piece 12 formed on one side, and a cylindrical stator 20 is installed on the fixed shaft 1 so as to be located outside the rotor 10. Gear trains are transmitted to the rotor 10 and the stator 20 so as to rotate the rotational power of the rotary cylinder 40 in the opposite direction.

However, since the above-described conventional low speed generator rotates the rotor and the stator in the reverse direction by using a plurality of gear trains in order to increase the relative speed, the configuration is complicated, assembly is difficult, the weight is heavy, and the manufacturing is expensive. .

The present invention has been made to solve the above-mentioned problems of the prior art. An object of the present invention is to provide a low-speed generator that can achieve the desired electromotive force in low-speed rotation by reducing the rotational resistance of the rotor by simultaneously rotating the rotor and the inner casing through a gear combination of a simple configuration.

In order to achieve the above object of the present invention, the present invention is a rotating shaft that rotates by external power, a cylindrical rotor fixedly coupled to the rotating shaft and rotated by the rotating shaft, and a magnet installed on the outer surface of the rotor and A cylindrical stator rotatably coupled with the rotating shaft to the outside of the rotor, a winding coil installed on the inner side of the stator and connected to an external wiring, and fixedly coupled to the rotating shaft and one side to the outside of the stator by a rotating shaft It provides a low-speed generator, characterized in that it comprises an outer casing coupled to the rotary shaft pedestal including a rotating cylindrical inner casing and the inner casing.

The low speed generator of the present invention may form a plurality of through holes on at least one surface of the stator and the casing in order to discharge heat generated therein to the outside.

In addition, the stator can couple the center of its two sides to the rotating shaft via a bearing.

In addition, the stator support member may be provided with a fixed gear on one side thereof and may be provided with a plurality of rotary gears to rotate in engagement with the fixed gear on the outer surface of the inner casing.

In addition, the stator may be fixedly coupled to the stator support member for rotatably supporting the rotating shaft. In addition, the outer casing may be fixed to the rotary shaft support on both sides thereof.

According to the low speed generator of the present invention, the relative speed between the magnet of the rotor and the winding coil of the stator is reduced by greatly reducing the rotational resistance applied to the rotor by simultaneously rotating the rotor to which the magnet is attached and the inner casing made of iron at the same time. It can be increased, thereby obtaining the desired electromotive force even at low speed.

In addition, the present invention can increase the relative speed of the rotor and the stator in a relatively simple configuration, such as bearings, rotary gears, fixed gears, so that the structure of the low-speed generator is simple, easy to assemble and low cost.

When applying low-speed rotational power such as tidal, wind and road generation, the desired electromotive force could not be obtained.

Hereinafter, a low speed generator according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail. 1 to 4, the low speed generator 100 according to the preferred embodiment of the present invention is a rotating shaft 101, the rotor 110, the stator 130, the inner casing 150, the outer casing ( 160).

The rotating shaft 101 rotates by the power generated by the external power generating means, and both ends thereof are rotatably supported by the rotating shaft support 102.

The rotor 110 is cylindrically fixed to the rotating shaft 101 so as to penetrate through the center thereof, and the magnet 111 is divided into 12 in this embodiment, which is divided on the outer peripheral surface thereof.

The stator 130 is located in the outer side of the rotor 110 in a hollow cylinder shape, and is made of a non-conductor coupled with a winding coil connected to an external wiring.

Side plates

133 and 134 are coupled to both side ends of the stator 130 by coupling means such as screws 131, and

bearings

135 and 136 are mounted at the centers of the

side plates

133 and 134.

The

bearings

135 and 136 are means for rotatably coupling the stator 130 and the rotation shaft 101 to each other, and the stator 130 is not affected by the rotation of the rotation shaft 101 due to the

bearings

135 and 136.

Side plate 134 is a stator support member 137 of the hollow-cylindrical cylindrical shape for supporting the stator 130 is fixedly coupled, the stator support member 137 is fixedly coupled to the external rotary shaft support (102). In addition, the stator support member 137 is fixedly coupled to the fixed gear 138, the rotating shaft 101 is rotatably coupled to penetrate the inside thereof. Accordingly, the stator 130 is always maintained in a stopped state regardless of the rotational force of the rotation shaft 101 by the stator support member 137 fixedly coupled to the rotation shaft support 102.

In addition, a plurality of winding coils 142 are attached to the inner circumferential surface of the stator 130. The winding coil 142 penetrates through the side plate 134 and is connected to a space between the side plate 154 and the stator support member 137, and a wire 143 which is drawn out through the fixing gear wiring hole and the outer casing wiring hole. Therefore, the current generated in the winding coil 142 may be transmitted to the outside along the wiring 143.

The inner casing 150 is located in the outer side of the stator 130 in a hollow cylinder shape, and made of iron.

Both side ends of the inner casing 150 are fixedly coupled to the

side plates

153 and 154 by coupling means such as screws 151, and the rotating shaft 101 is coupled to the

side plates

153 and 154 so as to pass through the center thereof.

The side plate 153 is fixedly coupled to the rotation shaft 101 via the fixing plate 152, and the side plate 154 is rotatably coupled by a fixed gear and a rotating gear coupled to the stator support member 137. Therefore, when the rotating shaft 101 rotates, the rotor 110 and the inner casing 150 fixedly coupled to the rotating shaft 101 rotate in the same direction, but the stator 130 rotatably coupled to the rotating shaft 101 is It is not rotated by the stator support member 137 fixed to the rotary shaft support 102.

In addition, the outer plate 154 of one end of the inner casing 150 is provided with a plurality of rotary gears 155 to be engaged with the fixed gear 138 is fixedly coupled to the stator support member 137. The rotary gear 155 rotates by rotating itself along the fixed gear 138 when the inner casing 150 rotates together with the rotation shaft 101, and supports the side plate 154 of the inner casing 150 to support the inner casing 150. ) Rotates to prevent the shaking of the inner casing (150).

The rotary gear 155 is preferably arranged in a stable four-angle or six-angle sphere so as to minimize the shaking of the inner casing 150, in this embodiment four rotary gears 155 in a four-angle sphere at 90-degree intervals. Installed.

Hereinafter, the operation of the low speed generator 100 of the present invention having the above-described configuration will be described.

When an external force is applied to the rotating shaft 101, the rotating shaft 101 supported by the rotating shaft support 102 is rotated.

When the rotating shaft 101 rotates, the rotor 110 and the inner casing 150 fixedly coupled to the rotating shaft 101 are rotated in the same direction. At this time, the rotating gears 155 installed in the inner casing 150 are engaged with the fixed gear 138 to rotate themselves along the outer circumference of the fixed gear 138 to rotate about the rotating shaft 101, and the stator 130 rotates. It is maintained by the stator support member 137 coupled to the pedestal (102).

Electric power generated by the magnet 111 installed in the rotor 110 and the winding coil 142 installed in the stator 130 passes through the side plate 134 along the wound coil 142 to form the side plate 154 and the stator. It is supplied to the outside through the space formed between the supporting member 137 and the wiring hole 143 of the fixed gear 138 and the wiring hole of the outer casing.

Therefore, since the rotor 110 and the inner casing 150 rotate together in the same direction, there is not much rotational resistance between the rotor 110 and the inner casing 150 and the rotor 110 rotates at low speed. Even if the relative speed between the magnet 111 of the rotor 110 and the winding coil 142 of the stator 130 is increased to obtain the desired electromotive force.

In addition, in the conventional low speed generator, the fixed gear 138 and the rotary gear 155 are often inward, so that the maintenance is often difficult, but according to the present invention, the maintenance is easy and the stator 130 is different from the prior art. ) Is fixed by the stator support member 137 does not rotate, the inner casing 150 is rotated by the fixed gear and the rotary gear 155.

In addition, in the related art, a winding resistance is generated by a magnetic field between the rotor and the stator by winding the conductor of the stator. In the present invention, the rotor and the inner casing are moved in the same direction by using the winding coil 142 wound on the non-conductor. When rotating, a magnetic field is induced between each other, but the non-conducting stator generates electromotive force to achieve natural rotational force without resistance.

Although the low speed generator of the present invention has been described above with reference to a preferred embodiment of the present invention, it will be apparent to those skilled in the art that modifications, changes, and various modifications can be made without departing from the spirit of the present invention.
