The present invention relates to a hybrid type high efficiency generator, and more particularly, a transmission device is installed between generators configured to interlock with a brush less direct current motor (BLDC motor), A generator having a fluid coupling and a flywheel and improving the arrangement of the rotor and the magnetic induction iron core constituting the generator and the winding and wiring method of the induction coil, wherein the shift is installed between the brushless DC motor and the generator. Induced by reverse current generated in the induction coil by improving the output of the power generation device by shifting the rotational speed and the rotation force by the device, and improving the arrangement structure of the rotor and the magnetic induction iron core and winding and connection of the induction coil. By blocking and canceling magnetization and making it non-magnetic, it is possible to produce a large amount of electrical energy with the same kinetic energy. It relates to a hybrid-type high-efficiency power generator.

In addition, the fluid coupling is to keep the output always constant even by sudden load change due to the detachment of the flywheel.

When a permanent magnet N pole or S pole is moved to a coil (conductor), electromotive force is generated by a change of magnetic flux (magnetic flux linkage) passing through the coil. Such a shape is called electromagnetic induction.

At this time, the generated electromotive force is referred to as induced electromotive force, and the current flowing therein is referred to as induced current.

The direction of the electromotive force due to the electromagnetic induction is determined by the direction in which the permanent magnet moves to the conductor, and the polarity (N pole, S pole) of the permanent magnet.

Lenz's law and Fleming's right-hand law are one of the methods of electron induction.

In the direction of induced electromotive force, Lenz's law defines that induced electromotive force occurs in the increasing direction when decreasing in the direction of decreasing magnetic flux through the coil, and the induced current flows. In other words, induced electromotive force is generated in the direction of disturbing the change of magnetic flux.

In addition, Fleming's right hand rule states that the direction of induced electromotive force generated when the conductor breaks the magnetic flux is to extend the thumb, forefinger and middle finger with the right hand at right angles, the forefinger in the direction of the magnetic field, and the direction of thumb movement. When pointing, the middle finger defines the direction of induced electromotive force.

In addition, a generator is used such a property of electromagnetic induction.

Such a generator is a device that converts kinetic energy generated from various energy sources into electrical energy, and all generators generate electromotive force by using the electromagnetic induction action as described above.

By the way, a typical generator mechanically rotates a magnet or a conductor to generate electricity, in which a reverse current generated by electromagnetic induction flows in the coil, and an antimagnetic property is formed to attract the rotor, thereby rotating the rotor itself. Unnecessary loads, more than twice that of electricity

Thus, conventional generators have the drawback that their efficiency is generally low.

The present invention is to install a transmission device between the generator configured to interlock with the brushless DC motor in order to solve the above conventional drawbacks, install a fluid coupling and a flywheel to one side of the generator, to configure the generator By improving the arrangement structure of the rotor and the magnetic induction core and the winding and connection method of the induction coil, the rotation speed and the rotation force are changed by the transmission device installed between the brushless DC motor and the generator to increase the output of the power generator. By improving the arrangement of the rotor and the magnetic induction core and the winding and wiring method of the coil, the induction magnets caused by the reverse current generated in the coil are canceled and canceled to demagnetize a large amount of electrical energy with the same kinetic energy. The purpose is to provide a hybrid type high efficiency power generation device capable of producing.

In addition, the purpose of the fluid coupling and the flywheel on one side of the generator to keep the output constant even by sudden load changes.

The power generation apparatus according to the characteristics of the present invention for reducing the above object is a transmission device 12 between the generator 20 configured to interlock with a brush less direct current motor (BLDC motor) 10 And increase the output by shifting the rotational speed and the rotational force, and the arrangement structure of the rotor 22 and the magnetic induction cores 24a and 24b constituting the generator 20 and the winding of the sensitive coil 26 and By improving the wiring method, it is possible to produce a large amount of electrical energy with the same kinetic energy by demagnetizing by blocking and canceling the induction magnetic by the reverse current.

In addition, the one side of the generator 20 is provided with a fluid coupling 30 and a flywheel 32 to keep the output constant even by sudden load changes.

Figure 1 is a simplified block diagram of the overall configuration of the present invention, a transmission device 12 between the generator 20 of the present invention configured to interlock with a brushless direct current (BLDC) motor 10 as shown in FIG. ) Is installed.

In addition, one side of the generator 20 is provided with a fluid coupling 30 and a flywheel 32.

In addition, in order to operate the brushless direct current (BLDC) motor 10 and the generator 20 configured as described above more efficiently, the brushless direct current (BLDC) motor toward the brushless direct current (BLDC) motor 10 side. The control device 40 is provided, and the dummy load control device 50 and the load blocking device 60 are provided on the generator 20 side.

The brushless DC motor control device 40 and the dummy load control device 50 provided as described above are connected to the main control device 70, and the main control device 70 includes the main power supply device 72 and the display device. 74 is connected and comprised.

On the other hand, the arrangement structure of the rotor 22 and the magnetic induction core 24a, 24b constituting the generator 20 and the winding and connection method of the sensitive coil 26 are improved as shown in FIGS. 2 and 4. It consists of a structure.

Accordingly, the present invention configured as described above will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 1, the transmission 12 installed between the brushless direct current (BLDC) motor 10 and the generator 20 shifts the rotational speed transmitted from the brushless direct current (BLDC) motor 10. It is to be transmitted to the generator 20 by the rotational force, at which time the transmitted rotational speed is reduced to 4: 1 while improving the torque by about four times.

For example, when the rotational speed of the brushless direct current (BLDC) motor 10 is rotated at 2500rpm, the rotational speed transmitted to the generator 20 becomes 625rpm, and the rotational force of the generator 20 decreases four times, and the torque is Will increase.

The fluid coupling 30 and the flywheel 32 installed at one side of the generator 20 are separated from the flywheel 32 until the brushless direct current (BLDC) motor 10 and the generator 20 are normally rotated. When the rotational speed of the generator 20 is normal, the flywheel 32 is connected and rotates together with the generator 20. When a sudden load change occurs, the flywheel 32 may be rotated. By keeping the output constant at all times, the flywheel 32 generates a force proportional to the weight.

On the other hand, the brushless DC motor control device 40 provided to the brushless DC (BLDC) motor 10 side, the brushless DC motor power supply 41, the main processing device 42, The current / voltage detector 43, the position detection encoder 44, the driver module 45, and the transistor module 46 are constituted.

In addition, an A / D converter 47 and an analog input comparator 48 are provided to convert the analog signal transmitted from the main controller 70 into a digital signal.

The brushless direct current motor control device 40 configured as described above rotates the brushless direct current (BLDC) motor 10 in the conventional speed detector 14 provided on one side of the brushless direct current (BLDC) motor 10. The speed is detected and transmitted, and the speed of the brushless direct current (BLDC) motor 10 is fixed because a normal pulse circuit, a calculation circuit, a power supply circuit, and the like are built in the brushless DC motor control device 40. To maintain the power supply of the driver module 45 as the control power + 5V ± 5V through the brushless DC motor power supply 41, and the main processor 42 is a speed signal from the main controller 70. The driver module 45 and the transistor module 46 receiving the signal supply power to the brushless direct current (BLDC) motor 10 by switching a voltage.

The input current of the brushless direct current (BLDC) motor 10 is fed back to the main processing unit 42 through the current sensor, the speed and the position through the position detection encoder 44 to perform the current control and the speed control.

The position detection encoder 44 connected to one phase of the brushless DC motor coil detects and operates the positions of the N pole and the S pole, thereby turning the transistor module 45 on and off in the May process unit 42 so that the motor coil is turned on. Make sure it is energized.

At this time, in the same manner, each phase independently switches the voltage, so that the brushless direct current (BLDC) motor 10 starts and rotates smoothly.

For example, the two-phase motor of the three-phase motor has an electrical angle of 120, and by inputting the part wave and the square wave, the main controller 70 can control the pulse width modulation (PWM) of low frequency.

Thus, minimizing di / dt losses results in improved efficiency and higher reliability.

The dummy load control device 50 provided on the generator 20 side controls the starting torque of the generator 20 to smoothly start the brushless direct current (BLDC) motor 10.

As shown in FIG. 4, the dummy load control device 50 is connected to the electromotive force coil 26a and the counter electromotive force coil 26b. The dummy electromotive force control circuit 52, the digital signal processor 53, The power generation phase angle detector 54, the counter electromotive force phase angle detector 55, the logic (LOGIC) converter 56, and the A / D converter 57 are comprised.

The back EMF control circuit 52 is formed by connecting a silicon controlled rectifier (SCR) 1, a silicon controlled rectifier (SCR) 2, a resistor 52a, a capacitor 52b, and a gate driver unit (GDU) 52c.

As described above, when the signal is received from the main controller 70, the A / D converter 57 converts the signal into a digital signal and is input to the digital signal processing apparatus 53 to generate the power phase angle detector 54 and the counter electromotive force phase angle detector ( 55) The power generation phase angle and the counter electromotive force phase angle are detected, and the power generation phase angle is controlled between 0 ° to 30 °, 150 ° to 180 ° according to the signal of the main controller 70, and only the remaining 30 ° to 150 ° can be used. The signal is controlled so as to be controlled by the digital signal processing apparatus 53 so that it can be controlled.

5 shows waveforms for the respective portions by the counter electromotive force regulating circuit 52, in which the power generation waveform generated at the electromotive force coil 26a side is shown in the ① portion, and the power generation waveform generated at the side EMF coil 26b side is indicated in the ② portion. The offset waveform will appear.

In addition, in the part 3, as described above, the phase angle is canceled by controlling the angle between 0 ° to 30 ° and 150 ° to 180 ° according to the signal of the main controller 70, and the remaining 30 ° to 150 ° only. The power generation output waveform generated by synthesizing the power generation waveform and the offset waveform passing through the silicon controlled rectifier (SCR) 1 and the silicon controlled rectifier (SCR) 2 is shown.

More specifically, since the power generation waveform is the normal waveform and the cancellation waveform is the waveform in the opposite (reverse) direction to the normal waveform, the silicon controlled rectifier (SCR) 1 cancels the 0 ° to 30 ° and the 150 ° to 180 ° of the + waveform. The silicon controlled rectifier (SCR) 2 cancels the 180-210 degrees and 330-360 degrees of the-waveform.

Therefore, the power generation waveform is left at 30 ° to 150 ° on the + side and 210 ° to 330 ° on the − side, and the portion where the counter electromotive force is generated most is canceled, and only the waveform is used as the power generation output waveform.

In addition, the dummy load control device 50 always minimizes the current of the brushless direct current (BLDC) motor 10, and when the load of the generator 20 is small, the dummy load control device 50 consumes a lot of load. When the load of the generator 20 is large, the dummy load control device 50 consumes less load, so that the current flowing through the brushless direct current (BLDC) motor 10 flows at least as little as the generator 20. It will increase the power generation efficiency.

In addition, when the permanent magnet 23 of the rotor 22 constituting the generator 20 is rotated in a predetermined direction, the magnetic flux is rotated at both ends of the magnetic induction cores 24a and 24b by the rotation. The magnetic induction occurs as it crosses, and current flows along the winding direction of the sensitive coil 26, and a reverse current by electricity, that is, a reverse magnetic field is formed, which is induced in both the positive and reverse directions, and the reverse electromotive force control circuit ( 52, the silicon controlled rectifier (SCR) 1 and the silicon controlled rectifier (SCR) 2, which control the phase angle, minimize the counter electromotive force and thus have little effect on the permanent magnet 23 of the rotating rotor 22.

6 shows a change in the counter electromotive force of the generator, when the brushless direct current (BLDC) motor 10 as the driving motor starts and the load rises about 10%, the brushless direct current ( BLDC) current flowing through the motor 10 is increased by about 80%, and if the load of the generator 20 is increased by 80%, the current of the brushless direct current (BLDC) motor 10 is reversed to decrease the load of the generator 20 In the case of a lot of hanging state, the current flowing in the brushless DC (BLDC) motor 10 flows to the contrary and acts as opposed to the conventional generator, the generator 20 of the present invention is brushless when the load is light Since the current of the direct current (BLDC) motor 10 becomes 80% of the capacity of the brushless direct current (BLDC) motor 10, in practice, if the load is small, the brushless direct current (BLDC) motor 10 is caused by the counter electromotive force of the generator 20. ) Increases the current.

In addition, the load blocking device 60 is automatically cut off in order to protect the generator 20 when an error occurs in the load connected to the generator 20 side.

The brushless direct current motor control device 40 and the dummy load control device 50 provided as described above are connected to the main control device 70 to output the brushless direct current (BLDC) motor 10 and the generator 20. This ensures that the relationship is maintained accurately so that a consistent and stable output is obtained at all times.

The main power supply device 72 connected to the main control device 70 and supplying input power to the brushless DC motor 10 side uses a commercial AC power or a storage battery in parallel. ) Displays the operation state of the brushless DC motor control device 40, the dummy load control device 50, the main power supply device 72, it is possible to efficiently monitor the operation of the power generator.

On the other hand, the generator 20 is a rotor 22 having a rotating shaft; and the permanent magnet 23 of the north pole and the south pole alternately arranged around the rotor 22; and the permanent magnet 23 A pair of winding cores 25a and 25b is formed between the pair of magnetic induction cores 24a and 24b formed at appropriate intervals at the periphery of each of the winding cores 25a and 25b, respectively. The sensitive coil 26 is wound in a direction to be configured.

As shown in Figs. 2 and 4, the sensitive coil 26 is composed of a pair of electromotive force coils 26a and a counter electromotive force coil 26b, and is drawn out to an intermediate terminal 26c in the middle thereof, and thus the counter electromotive force coil 26b. And the intermediate terminal 26c are connected to the back EMF control circuit 52 constituting the dummy load control device 50.

Further, the pair of electromotive coils 26a and the sensitive coils 26 wound around the counter electromotive coils 26b are wound in opposite directions.

In addition, the output of the generator 20 is obtained at the output terminal 27 at the end of the electromotive force coil 26a and the end of the intermediate terminal 26c.

Therefore, the coiled and wired system as described above has a coil in which the coil is wound around the winding cores 25a and 25b of the generator 20 when the generator generates power, that is, when the closed circuit is configured by the coil 24. An electric current is induced at 26 to generate an induction magnetic field generated by each of the sensitive coils 26, which causes a large load to interfere with the rotational force of the rotor 22. However, the electromotive force coil constituting the sensitive coils 26 The winding direction of 26a) and the counter electromotive force coil 26b is wound in the opposite direction, whereby the magnetic force generated by the reverse current (induction current) in the coil 24 wound around the winding cores 25a and 25b is the magnetic induction core. It is not transmitted to (24a) and (24b), and consequently, reverse magnetism is not transmitted to the permanent magnet (23).

That is, the induction magnetic field generated in the induction coils 26 wound in opposite directions is made to be non-magnetic by blocking and canceling the induction magnetic force by reverse current.

Therefore, the electric power larger than the force for rotating the rotor can be obtained by blocking and canceling the induction magnet.

7 shows a back EMF control circuit 52 connected to a three-phase generator according to another embodiment of the present invention, wherein the back EMF control circuit is also the same as described in the generator 20 (single phase generator) of the present invention.
