Description

To reduce load torque on the multi pole and phase D.C generator}

The present invention relates to a power generation bundle in the power generation motive power generating rotational power during the patent registration No. 10-1155124, more specifically in order to rotate the generator, external driving force, that is, no-load torque (torque) and load torque is required. . Among them, the present invention relates to load torque, and to reducing the load torque and simultaneously integrating the output generated from the bundle of power coils wound in a multi-phase individual winding.

In general, a generator is widely used as a means for securing electricity by converting mechanical energy into electrical energy using an external driving force.

The above-described generator will be described with reference to the accompanying drawings. For simplicity, the external power of the generator will be used as an electric motor, and the magnet attached to the rotor of the generator will be described as a permanent magnet.

1, 2, 3, 4, 5, and 6 are views for explaining the concept of the present invention,

1 is a description of some of the objects of the present invention.

FIG. 1A is a diagram in which the motor 2000 generates a rotational force, that is, a torque by consuming a single operation current of a (A).

1B is a shape in which the motor 2000 rotates the rotor 20 of the generator 3000 connected to the rotary shaft 10. The generator 3000 forms an induced electromotive force of E (V), and also generates a generator ( In the shape of supplying additional torque to rotate the rotor 20 of the 3000, the motor consumes an additional current of a (A) and a current of b (A) to supply additional torque.

In other words, the generator 3000 needs a force to rotate the rotor 20, that is, torque, in order to obtain the induced electromotive force of E (V), and the motor consumes a (A) + b (A) so that the generator In the present invention, the torque required is called a no-load torque.

1C is a shape in which the motor 2000 rotates two rotors of the generator 3000. The output is E (V) + E (V). In other words, the motor consumes an additional b (A) to b (A) in order to supply single operation current a (A) and no-load torque required by two generators, thereby a (A) + b (A) + b (A). Is consuming.

If two units are used as shown in FIG. 1B to form an induced electromotive force of E (V) + E (V), the two motor current consumptions are 2a (A) + 2b (A) and a (A The single operation current of) is additionally consumed. That is, when n generators are installed in one motor, the effect of reducing the single operation current of (n-1) * a (A) occurs. Therefore, as will be described later, the present invention is to provide a plurality of generators, and in order to reduce the rotational resistance generated in the same way, the plurality of generators maintain a constant phase angle, and as a result, a single operating current of (n-1) * a (A) Is characterized by decreasing.

1D illustrates a normal operation state of the generator 3000. When two generators 3000 are supplied with no-load torque and the load of x (W) is connected to the induced electromotive force E (V) + E (V) obtained by the rotor 20 rotating, the voltage of e (V) is obtained. And a current of x (A) is generated, and further torque is required by a resistance that suppresses the rotor 20 of the generator by the current of x (A), and the electric motor 2000 is additionally required. In the present invention, additional torque is supplied by consuming a current of c (A) with respect to the torque. In the present invention, the additional torque required at this time is referred to as load torque, and the sum of no-load torque and load torque is fully loaded. Called torque,

1A and 1D, the generator 3000 needs a full load torque to supply a load, and in detail, a no load torque is required to form an induced electromotive force, and to supply a load. It is a figure for demonstrating that load torque is necessary in order.

As described above, the generator requires no load and load torque, and briefly summarizes the object of the invention.

Patent registration No. 10-1155124 aims to reduce the total load torque,

Patent registration No. 10-1218474, if the purpose is to reduce no-load torque,

Patent application 10-2012-0154208 and the present invention aim to reduce the load torque.

For reference, in order to easily understand the effect that the load torque is reduced, after calculating the generator output and the pulling force, that is, the maximum load torque of the improvement target, and calculating the generator output and the pulling force, that is, the maximum load torque after the improvement, To compare,

In addition, in order to calculate the output and the pulling force of the generator, i.e. the maximum load torque, the method of expressing the magnitude and torque of the magnetic force for the permanent magnet is described first.

Fig. 2 describes a method of expressing the magnitude of the magnetic force and the torque only in the present invention.

Figure 2a, b, c is a diagram illustrating the terms used in the present invention, the upper m1 permanent magnet is fixed, the lower part there is a movable m2 permanent magnet, each permanent magnet corresponds to the opposite pole Doing.

In FIG. 2A, the p2 point of the lower m2 permanent magnet is pulled by the force of F2, and the pull point is pulled by the force of F1 until it is perpendicular to the p1 point of the upper m1 permanent magnet. And his size is F1 + F2. In other words, it progresses with the force of F1 + F2.

FIG. 2B is pulling each other at a point where the points of each permanent magnet p1 and p2 vertically coincide with each other and are stopped. The force at this time is called the pulling force, and the size is F1 + F2. At this point, external force is required to proceed, and its size must be larger than F1 + F2.

2c shows that the lower m2 permanent magnet is in progress and the upper m1 permanent magnet is being pulled. This force is called a reverse pulling force, and the magnitude is F1 + F2. At this point, external force is required to proceed, and its size must be larger than F1 + F2.

2A, b, and c, the pull force is divided into a pull force, a pull force, a reverse pull force, in the drawing the magnitude of the jeongdamgi force F1 + F2, the magnitude of the pull force is F1 + F2, reverse pull force The size of F1 + F2.

As described above, the types of pulling force are classified, but the magnitude is expressed in the same manner as F1 + F2. Therefore, in order to simplify the explanation, it is necessary to subdivide the force of magnetic force.

2d, e, and f are subdivided into the force of the magnetic force is shown by dividing each of the upper m1 permanent magnets and the m2 permanent magnets in the lower portion of each.

The magnitude of the calming force of FIG. 2D proceeds to 1, that is, the just force of 1.

The magnitude of the pulling force of FIG. 2E is 5, i.e., the pulling force of 5, and 5 or more external forces are required to move.

The magnitude of the back pull force of FIG. 2F is 2, that is, the back pull force of 2, and two or more external forces are required to move.

2g, h, i, j is a graph representing the drag force, pull force, reverse pull force in a graph.

In FIG. 2g, the lower permanent magnet m2 is lower than the upper permanent magnet m1 and passes through the distance L1 to the right at t1 hours.

2H is a graphical representation of progress. In the drawing, the magnetic force starts from 0 to party force, proceeds to 5 party force or pull force point, and then shows the reverse force to the point of zero.

Figure 2i is a graph that distinguishes the force of the magnetic force and the external power, the force of the magnetic force is negative (-), the force of the external power is displayed as a graph divided by a positive (+). Therefore, the magnitude of the magnetic force, that is, the instantaneous maximum value is -5, and the magnitude of the external power, the instantaneous maximum value, is expressed as 5,

Figure 2j is the magnitude of the external power, that is, the maximum instantaneous value is represented by 5.

Therefore, in FIG. 2g, the lower permanent magnet m2 needs to have an external power of 5 to pass through the upper permanent magnet m1, which will be described later. Can be.

3 is a plan view and a side view of a generator coil, and shows that the representation of the plan view during normal operation of the generator is divided into three types in the present invention. That is, three types of phenomena of normal operation of the generator will be described, and FIG. 3 will be described.

The six permanent magnets 26a to f and the rotation shaft 10 are integrated in the rotor 20 having a radius r that rotates in FIG. 3a, and have a predetermined interval (void) according to the circumference of the rotor 20. Since the rotor is rotating in a shape in which six power coil bundles 32a to 32f of individual windings wound n times on the stator 30 are arranged,

Each of the power generating coil bundles 32a to 32f is a drawing of the induction electromotive force E (V). In particular, each of the power generating coil bundles 32a to 32f is not connected to each other. The shape in which E (V) induced electromotive force was generated alone was expressed as having n pieces by displaying the power coil in a circle.

For reference, in the present invention, the width of the permanent magnet, the width of the power coil bundle, and the winding of the power coil bundle will be described.

First, the width of the permanent magnet and the width of the power coil bundle are described.

Although not specifically shown, Patent Publication No. 10-1155124, page 10, line 10, Fig. 9-10 describes that the time of rotational resistance at the time of supplying the load is the smallest when the width of the permanent magnet and the width of the power generation coil are the same. It is characterized by the same width of permanent magnets and power coil bundles, and unless otherwise specified, the width of permanent magnets and power coil bundles shall be the same.

Next, the winding of the power generation coil bundle will be described.

Typically, the windings of a generator are wound in various ways. For example, although not shown in the drawings, it is divided into a ring circle, a solid ticket, an open ticket, a derogation ticket, and a middle ticket, a wave ticket, and the like. In other words, after the power coil has passed through n slots and slots of the stator n times, the power coil is connected to the middle winding or the breaking winding to configure the output terminal.

Although the winding of the present invention will be described later, the coil is repeated several times in each of n slots of the stator to make one power coil bundle to configure n outputs.

Therefore, the number of outputs is the same as the number of slots of the stator. In the present invention, the method of winding as described above is called an individual winding and is also a feature of the present invention.

FIG. 3B is a side view showing the electric power bundle 32a wound on the stator 30 in the individual windings to form individual outputs,

Figure 3c is intended to simply express the above-described relationship by using the symbol of the coil, in particular, the representation of the figure represents that six power coil bundles 32a to 32f are generating output, and the output terminals are also the same six Drawing,

3D illustrates that the magnetic force is generated when a current flows through the bundles of power coils 32a to 32f. Thus, the bundle of power coils is represented by permanent magnets. The purpose of this expression is to load load torque by the method described in FIGS. 2D, e, and f. It is to calculate the torque.

As described above, in the present invention, the three generators used in the present invention and the generator after improvement are used in combination.

4 is a diagram representing no-load torque and load torque required for the generator,

Figures 4a and b show no-load torques, and Figures 4c and d refer to load torques.

In FIG. 4A, the rotor 20 having the permanent magnet 26 having the width w and height b is coupled to the rotation shaft 10, and n coils of the cross-sectional area A are individually wound into the slots w width and h height. The no-load torque required for the rotation of the rotor 20 in the state of rotating the power generation coil bundle of length l wound by the power generation coil bundle is the induced electromotive force of E (V). To form.

4b shows that the generator rotor 20 requires no-load torque in order to rotate, and this graph shows no-load torque as a graph.

In FIG. 4C, when a load of a (W) is connected to a bundle of power generation coils, a current of x (A) is generated, and thus, the power generation coil bundle represents a permanent magnet generated by a permanent magnet. It is a drawing expressing the need for load torque by acting as a pulling force on the permanent magnet 26 of 20). In other words, the generator needs no-load torque and load torque.

4D is a graph showing no-load torque and load torque. Referring to Figures 2h, i, j No. 1 is a section in which the rotational force is generated by the force applied to the point that coincides with the p2 point of the rotor and the p1 point of the power coil bundle, and load torque is required due to the generation of the rotation force It is a section without a point, and from the coincidence point, the number 2 is a section in which reverse pull force is applied and a load torque is required. In addition, it can be seen that when the load is supplied, the momentary force acts every revolution, and the no-load torque is partially reduced every revolution.

Therefore, as described later, Patent Registration No. 10-1155124 and the present invention are characterized in that the rotational force is partially generated during load supply, and the no-load torque is partially reduced due to the partial generation of the rotational force.

For reference, the waveform of the load torque of Figure 4g is the same as the waveform of the motor input current. Therefore, when measuring the input current value, the instantaneous maximum value and the average value or cumulative value after a certain time are expressed differently, and in particular, the protective device of the motor is preferably selected as the instantaneous maximum value. Therefore, detailed description is omitted.

5 and 6 are views showing a method of calculating the size of the permanent magnet in the present invention, Figure 5 is a diagram representing the size of one surface of the permanent magnet.

In FIG. 5A, a permanent magnet having a height d and a width 1 / 12w is divided into 12 sums or a permanent magnet having a height d and a width w as 12, and the size of the permanent magnet having a height d and a width of 1 / 12w is 1F. The magnitude | size of the permanent magnet 26 of height d and width w is 12F.

FIG. 5B shows that the sum of two permanent magnets having a height of 1F and a width of 1 / 12w, that is, the size of the permanent magnets having a height of d and a width of 1 / 6w is 2F, and the sum of six permanent magnets of 2F is 12F. It is a figure to express.

FIG. 5C is a diagram representing that the sum of 12 permanent magnets having a size of 1F and a height d and a width of 1 / 12w is 12F.

Figure 5d is a size of 1F, when the permanent magnet of height d, width 1 / 12w is reduced to 1 / 2d in height, 1 / 12w in width, its size is reduced to 1 / 2F, size is 1 / 2F, height 1 The sum of 12 permanent magnets of / 2d and 1 / 12w in width is 6F.

6 is a diagram representing the magnitude of the pulling force acting between the permanent magnets arranged on the upper side and the lower side.

In FIG. 6A, the size of each of the upper and lower layers of 12F and the height of the permanent magnets d and the width w of the permanent magnets are 12F + 12F = 24F.

In FIG. 6B, the upper layer has a size of 2F and the sum of six permanent magnets having a height d and width 1 / 6w is 12F and the lower layer has a size of 2F and the sum of six permanent magnets having a height d and width of 1 / 6w is 12F. The magnitude of the pulling force that the permanent magnets interact with each other is 12F + 12F = 24F.

In FIG. 6C, the sum of 12 permanent magnets having a height of 1F and a width of 12 and a width of 1 / 12w is 12F, and the sum of 12 permanent magnets having a height of 1F and a height of 12 and a width of 1 / 12w is 12F. The magnitude of the pulling force that the permanent magnets interact with each other is 12F + 12F = 24F.

In Fig. 6d, the upper layer has a size of 1 / 2F and the permanent magnets having a height of 1 / 2d and a width of 1 / 12w of 12 permanent magnets are 6F and the lower layer has a size of 1F and 12 permanent magnets having a height of d and width of 1 / 12w. The magnitude of the pulling force acting on each other by permanent magnets having a sum of 12F is 6F + 12F = 18F.

In particular, although described later in Figure 6b, c, d, the upper side is the magnetic force of the power coil bundle of the stator, the lower side is the permanent magnet of the rotor to calculate the magnitude of the pulling force. For example, if the sum of the magnetic forces of the power coil bundle attached to the stator is 12F and the sum of the magnetic forces of the rotor permanent magnet is 12F, the pulling force is 24F. Therefore, the maximum torque required of the generator is expressed as 24F.

The concept of the present invention and the method for calculating the load torque of the generator have been described.

When the magnetic force of one permanent magnet having width 1 / 6w and height d is 2F, the magnetic force is 12F when the quantity is 6, and the magnetic force of the rotor 20 is b when 12F,

If the coil of the cross-sectional area A is wound n times with the width of 1 / 6w of the stator slot and the height h, it is formed one bundle of power coil and the length of power coil is called l.

If the linear velocity of the rotor is v,

The induced electromotive force obtained from one bundle of power generation coils is b * l * v,

The sum of the induced electromotive force obtained from six power coil bundles is 6 * (blv). That is, the generator of the improvement target has a total weight of the rotor permanent magnet of 6w (g), the magnetic force is 12F, the output of one bundle of power generation coil is blv, and the total output of the generator of the improvement target is 6blv.

In addition, for the sake of simplicity in the present invention, when the output of blv is the magnitude of the magnetic force generated in one bundle of power coils, if the expression is 2F, the output generated in the six bundles of power coils of the stator is 2F * 6 = It can be written as 12F.

In addition, the permanent magnet attached to the rotor 20, each weight is w (g) when the rotor 20 is rotated, each permanent magnet is wv² / r in the size of centrifugal force is generated to escape to the outside I will try to. In other words, the centrifugal force must be reinforced separately, which increases the weight of the rotor 20, and summarizes the above description in Table 2.

In response to the six power coil bundles 32a to 32f forming a pulling force,

The magnetic force of the permanent magnet is 2F when the size is 1 / 6w wide and d is high.

Since the magnetic force of the power coil bundle is 2F when the output is blv,

The total magnetic force of six permanent magnets 26a to 26f of the rotor 20 is 2F * 6 = 12F,

The total magnetic force of the six power coil bundles (32a to 32f) is 2F * 6 = 12F,

The torque required by the generator to be improved is 12F + 12F = 24.

There is a problem that the pulling force of the generator, that is, the load torque acts at the same time.

In addition, the permanent magnet has a problem in that the centrifugal force is generated in the size of wv² / r, so that the permanent magnet is reinforced separately.

In addition, there is a problem that the weight of the rotor increases due to reinforcement.

In addition, although described later, the output coils cancel each other due to the phase difference when the bundles of power coils are connected, and there is a problem of supplying only a part of the remaining outputs to the load.

An object of the present invention devised to solve the above problems is to provide a multi-pole multiphase DC generator in which load torque is reduced by inserting an auxiliary coil and attaching a stop.

Load torque consisting of a plurality of slots and windings of power coils 32 wound by individual windings, in which a non-metal stator is additionally divided into two vertical lines, so that the magnetic forces on the left and the right cancel each other out. As a plan view of a multiphase multipole DC generator,

The stator material is made of non-metal to prevent the rotation of the rotor (see patent application 10-2012-0154208, page 28, lines 31-32).

The material of the rotor is non-metal to reduce the no-load torque by reducing the weight and to prevent the rotation of the rotor by the magnetic force of the power bundle coil (see Patent Registration No. 10-1218474, page 10, line 87-89). ),

 In this figure, the rotor 20 has a weight w (g), and six permanent magnets having a height d and a width of 1 / 6w are attached, and the stator 30 has a slot of height h and width of 1 / 6w and power generation. The coil bundles are arranged in the form of 'Table 4'.

The following describes the integration of the output from the bundle of power generation coils.

16, 17, 18, 19, and 20 show a fifth embodiment for integrating an output generated from a power coil bundle.

16 and 17 are related to the wiring of the output generated from the power coil bundle wound by the individual winding of the generator to be improved,

16 relates to connecting the output of one generator to be improved.

FIG. 16A illustrates an example of a method of connecting a load to the respective power coil bundles 32a to f generated by the power coil bundles 32a to f wound around the individual windings of the generator to be improved.

Figure 16b is to connect in series or in parallel the output generated from the power coil bundles (32a ~ f) wound by the individual windings of the generator to be improved, this figure is connected to the load in parallel inside the generator as an example to connect the load To show that

Figure 16c is a connection in parallel in the interior of the generator has the trouble of dismantling the wiring when assembling or replacing the power coil bundle, in order to simplify the process, although not shown, each power coil to the outside of the stator cover Drawing to draw and connect to the busbar 39 is to express the connection of the load by connecting each bundle of power coils (32a ~ f) in parallel.

Referring to Figure 7b, Figure 7b, in order to prevent the rotational resistance to occur at the same time to maintain a constant phase angle, in this figure, four generators each maintain a phase angle of 15 degrees and a stator cover attached to the busbar 39 Including 40, the bus bar 39 is connected to a single generator.

For reference, in general, when describing the parallel operation conditions of the generator,

1. The rated voltage is the same (prevents the flow of reactive circulating current),

2. match phase (synchronized current flow),

3. The rated frequency is the same (cause of hunting), etc.

It is said that parallel operation is possible only when three requirements are satisfied.

However, FIG. 17A is a shape in which four sets of busbars 39 are operated in parallel to each other so that a synchronization current flows.

17B is a shape in which four sets of busbars 39 are driven in series to drive synchronization currents.

That is, the # 1 to # 4 generators 500 of FIGS. 17A and 17B have four phase angles of 15 degrees to each of the # 1 to # 4 generators 500 to prevent rotational resistance occurring at the same time as described above. Since it is maintained, there is a problem that the output of each of the generating bundle coils cancels each other and outputs only a part because of the phase mismatch.

17C is a shape in which each load is connected to four sets of busbars 39 to solve the above problems. However, even though the problem of connecting the load is solved, there is a problem in that the output of each of the four sets of busbars 39 cannot be integrated.

Fig. 18 relates to the phase of induced electromotive force generated in a bundle of power coils wound by a single winding of a multipole multiphase DC generator in which the load torque of the third embodiment is reduced.

FIG. 18C is a view representing drawing each of the power coil bundles 32a to m to the outside of the stator cover and connecting the bus coils 39 in parallel to load the power coils 32a to m. To express the concatenation.

At this time, the output of the busbar 39 expresses that only a part of the remaining output is offset to each other due to the phase difference between the bundles of power coils 32a to m wound by the respective windings.

That is, it is a diagram expressing that integration is impossible due to the phase difference.

19 is a view showing the integration of the output of one multi-pole multi-phase DC generator with a reduced load torque, which is impossible to integrate due to the phase difference, and outputs each of the output coil bundles 32a to m wound in individual windings. Shows how to connect 13 loads to the power coil bundle (32a ~ m).

18D and 19, the multi-pole multiphase DC generator having a reduced load torque has a problem in that, while the load torque is reduced, the output generated from the bundle of power coils wound in the individual windings causes a phase difference. .
