The rotation system in the embodiment of the present invention is a rotation system for rotating a rotation shaft having a load, and particularly has a motor on each side of the rotation shaft.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is an explanatory diagram showing an example of the structure of a rotation system according to a first embodiment of the present invention. In FIG. 1, in the rotating system 1, a first motor 20 and a second motor 22 are connected to both ends of a rotating shaft 10 having a load 5 via

shaft couplings

12 and 14, respectively.

The first motor 20 has a rotational force that is less than the rotational torque at the time of starting rotation of the rotary shaft 10 but is equivalent to the rotational torque at the time of steady rotation. Here, the steady rotation is a state in which the rotating shaft 10 rotates at a desired number of rotations. On the other hand, the second motor 22 has a rotational force that is the difference between the rotational torque at the start-up rotation of the rotating shaft 10 and the rotational force of the first motor 20.

For example, when the rotational torque at the starting rotation of the rotary shaft 10 is 1.0 and the rotational torque at the steady rotation is 0.4, the first motor 20 having a rotational force of 0.6 is used. The second motor 22 has a rotational force of 0.4. The rotational forces of the first motor 20 and the second motor 22 are merely examples, and are not limited to these values.

The second motor 22 has a structure capable of stopping the rotation without disturbing the rotation of the rotating shaft 10 while the rotating shaft 10 is rotating. Specifically, the second motor 22 itself has a structure in which the rotor rotates idly without generating a rotational force and does not consume energy, or a clutch is provided so that the second motor 22 is released from the rotating shaft 10. However, it is not limited by the structure.

In the rotation system 1 having such a configuration, when the rotation is started with the rotation shaft 10 stopped (when starting rotation), the first motor 20 and the second motor provided on both sides of the rotation shaft 10 are used. The rotating shaft 10 is rotated by both of them. Then, after the rotation shaft 10 starts to rotate normally, the rotation of the second motor 22 is stopped, and the rotation shaft 10 is rotated only by the first motor 20.

In addition, it can be used that the rotational torque of the rotating shaft 10 is not applied to the second motor 22 as a condition for stopping the second motor 22 by determining that the rotating shaft 10 has made steady rotation. In addition, there is another method for determining that the rotating shaft 10 is in a steady rotation when the rotating shaft 10 reaches a predetermined rotation speed. The steady rotation may be detected by other methods. Further, the first motor 20 and the second motor 22 may be motors having any structure as long as the above usage method is possible.

As described above, according to the rotation system 1 of the present embodiment, the rotation shaft 10 is rotated by both the first motor 20 and the second motor 22 during the start-up rotation of the rotation shaft 10, and the rotation shaft 10 is in a steady state. After the rotation starts, the rotation of the second motor 22 is stopped, and the rotation shaft 10 is rotated only by the first motor 20, so that the rotation shaft 10 can be rotated more reliably when a large rotational force is required. On the contrary, when only a predetermined rotational force is required, the rotational shaft can be efficiently rotated with the optimal rotational force.

Further, it is determined that the second motor 22 is in a steady state rotation because the rotation torque of the rotary shaft 10 is no longer applied to the second motor 22, and the second motor 22 is stopped so that the second motor 22 rotates unnecessarily. Therefore, the rotating shaft 10 can be rotated more efficiently. Moreover, even if it is determined that the rotation shaft 10 has reached a predetermined rotation speed and the rotation is steady and the second motor 22 is stopped, the second motor 22 is prevented from rotating unnecessarily. The rotating shaft 10 can be efficiently rotated.

In the first embodiment, various rotating objects are assumed as the load 5 to be rotated by the rotating shaft 10, but the present embodiment shows more specifically. Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 2 is an explanatory diagram showing an example of the structure of the rotation system according to the second embodiment of the present invention. In FIG. 2, the rotation system 2 has a first motor 40 and a second motor 42 connected to both ends of a rotation shaft 30 provided with a generator 6 as a load via

shaft couplings

32 and 34, respectively.

The first motor 40 has a rotational force that is less than the rotational torque at the time of starting rotation of the rotary shaft 30 but is equivalent to the rotational torque at the time of steady rotation. Here, the steady rotation is a state in which the rotating shaft 30 is rotated at a desired number of revolutions, which is necessary for efficiently generating power with the generator 6. On the other hand, the second motor 42 has a rotational force that is the difference between the rotational torque at the start-up rotation of the rotating shaft 30 and the rotational force of the first motor 40.

For example, when the rotational torque at the starting rotation of the rotary shaft 30 is 1.0 and the rotational torque at the steady rotation is 0.4, the first motor 40 having a rotational force of 0.6 is used. The second motor 42 has a rotational force of 0.4. The rotational forces of the first motor 40 and the second motor 42 are merely examples, and are not limited to these values.

The second motor 42 has a structure capable of stopping the rotation without disturbing the rotation of the rotating shaft 30 while the rotating shaft 30 is rotating. Specifically, the second motor 42 itself has a structure in which the rotor rotates idly without generating rotational force and does not consume energy, or a clutch is provided to release the rotary shaft 30. However, it is not limited by the structure.

In the rotation system 2 having such a configuration, when the rotation is started in a state where the rotation shaft 30 is stopped (when starting rotation), the first motor 40 and the second motor provided on both sides of the rotation shaft 30 are used. The rotating shaft 30 is rotated with both of them. Then, after the rotating shaft 30 starts to rotate steadily, the rotation of the second motor 42 is stopped, and the rotating shaft 30 is rotated only by the first motor 40 so that the generator 6 can efficiently generate power. To.

It should be noted that, as a condition for determining that the rotating shaft 30 has made steady rotation and stopping the second motor 42, the fact that the rotating torque of the rotating shaft 30 is no longer applied to the second motor 42 can be used. In addition, there is also a method for determining that the rotating shaft 30 has reached steady rotation when the rotating shaft 30 has reached a predetermined rotational speed. The steady rotation may be detected by other methods. Further, the first motor 40 and the second motor 42 may be motors having any structure as long as the above usage method is possible.

As described above, according to the rotation system 2 in the present embodiment, the rotating shaft 30 is the rotor of the generator 6, and the rotating shaft 30 rotates to generate electric power. When the rotating shaft 30 is rotated more reliably and only a predetermined rotating force is required, the rotating shaft 30 can be efficiently rotated with the optimal rotating force, thereby generating power more efficiently. .

In the first and second embodiments, the rotary shaft 10 and the rotary shaft 30 are directly provided with loads. However, in this embodiment, an example that does not have such a structure is shown. Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 3 is an explanatory diagram showing an example of the structure of the rotation system according to the third embodiment of the present invention. In FIG. 3, the rotating system 3 includes the generator 8 as a load, but does not include the generator 8 directly on the rotating shaft 50. In the rotation system 3, first, the flywheel 9 is provided at the center of the rotation shaft 50, both sides of the rotation shaft 50 are held via

bearings

52 and 54, and

shaft couplings

56 and 58 are respectively attached to both ends of the rotation shaft 50. The 1st motor 60 and the 2nd motor 62 are connected via.

And the generator 8 provided with the gearwheel 8a which contact | abuts to the outer periphery of the flywheel 9 and transmits rotation of the flywheel 9 to the generator 8 is provided.

The first motor 60 has a rotational force that is less than the rotational torque at the time of starting rotation of the rotary shaft 50, but is equivalent to the rotational torque at the time of steady rotation. Here, the steady rotation is a state in which the rotating shaft 50 rotates at a desired number of rotations, which is necessary for efficiently generating power with the generator 8. On the other hand, the second motor 62 has a rotational force that is the difference between the rotational torque at the time of starting rotation of the rotary shaft 50 and the rotational force of the first motor 60.

For example, when the rotational torque at the starting rotation of the rotating shaft 50 is 1.0 and the rotational torque at the steady rotation is 0.4, the first motor 60 having a rotational force of 0.6 is used. The second motor 62 has a rotational force of 0.4. The rotational forces of the first motor 60 and the second motor 62 are merely examples, and are not limited to these values.

The second motor 62 has a structure capable of stopping the rotation without disturbing the rotation of the rotating shaft 50 while the rotating shaft 50 is rotating. Specifically, the second motor 62 itself has a structure in which the rotor rotates idly without generating a rotational force and does not consume energy, or a clutch is provided so as to be released from the rotating shaft 50. However, it is not limited by the structure.

In the rotation system 3 having such a configuration, when the rotation is started in a state where the rotation shaft 50 is stopped (during start-up rotation), the first motor 60 and the second motor provided on both sides of the rotation shaft 50 are used. The rotating shaft 50 is rotated by both of them. Then, after the rotation shaft 50 starts to rotate steadily, the rotation of the second motor 62 is stopped, the rotation shaft 50 is rotated only by the first motor 60 while receiving the assistance of the flywheel 9, and the generator 8 To generate electricity efficiently.

It should be noted that, as a condition for stopping the second motor 62 after determining that the rotation shaft 50 has been in steady rotation, the fact that the rotation torque of the rotation shaft 50 is no longer applied to the second motor 62 can be used. In addition, there is also a method for determining that the rotation shaft 50 has reached a predetermined rotation speed when the rotation shaft 50 has reached a predetermined rotation speed. The steady rotation may be detected by other methods. Further, the first motor 60 and the second motor 62 may be motors having any structure as long as the above usage method is possible.

As described above, according to the rotation system 3 in the present embodiment, the rotating shaft 50 is connected to the rotor of the generator 8 via the flywheel 9 and the gear 8a, and the rotating shaft 50 rotates to generate power. Therefore, when a large rotational force is required, the rotational shaft 50 is rotated more reliably. On the contrary, when only a predetermined rotational force is required, the rotational shaft 50 is efficiently rotated with an optimal rotational force. Power generation can be performed efficiently.

Also, by providing the rotary shaft 50 with the flywheel 9, the rotary shaft 50 can be efficiently rotated during steady rotation. The flywheel 9 is not connected to the rotor of the generator 8 as in this embodiment, and the flywheel 9 is provided on the rotating shaft 50 separately from the generator 8, so that the rotating shaft 50 is connected to the flywheel 9. You may make it connect with the rotor of the generator 8 not through.

In each of the above embodiments, the type of the motor is not limited, but the various rotating shafts can be rotated more efficiently by using a DC motor as the motor.

In the first embodiment, various rotating objects are assumed as the load 5 to be rotated by the rotating shaft 10, but this embodiment shows more specifically. Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 4 is an explanatory view showing an example of the structure of the rotation system of the fourth embodiment according to the present invention. In FIG. 4, the rotation system 4 has a first motor 80 and a second motor 82 connected to both ends of a rotation shaft 70 provided with a generator 6 as a load via

shaft couplings

72 and 74, respectively. Both the first motor 80 and the second motor 82 are DC motors.

The first motor 80 is a motor having a rotational force equal to or greater than the rotational torque at the time of steady rotation of the rotating shaft 70, and the second motor 82 is also at the time of steady rotation of the rotating shaft 70, similar to the first motor 80. This is a motor having a rotational force equal to or greater than the rotational torque. Then, both ends of the rotating shaft 70 are rotated by the first motor 80 and the second motor 82 via the

shaft couplings

72 and 74, respectively, and the rotational force of the first motor 80 and the second motor 82 is increased. The composition is such that they are combined on the rotating shaft 70. Regarding the connection of the power source, the first motor 80 and the second motor 82 are connected in series to form one DC power source 84. In order to measure the voltage and current of the power source, the DC power source 84 portion is connected. A voltmeter 86 and an ammeter 88 are provided.

Then, for example, the same torque is used for the rotation torque of the rotating shaft 70 and the rotation force of the first motor 80 and the second motor 82. The rotational forces of the first motor 80 and the second motor 82 are merely examples, and are not limited to this configuration.

More specific experimental results will be described. First, as the first motor 80 and the second motor 82, DC motors rated for an input of 1.5 V are used, and the first motor 80 and the second motor 82 are used. The motor used was used as the generator 6.

First, unlike FIG. 4, only the first motor 80 is connected to the rotating shaft 70 of the generator 6, and the rotating shaft 70 of the generator 6 is rotated only by the first motor 80 connected to the DC power supply 84. As a result, the input of the first motor 80 (measured values of the voltmeter 86 and the ammeter 88) is 0.6V with a voltage of 1.5V and a current of 0.44A, and the rotating shaft 70 of the generator 6 is rotated. It was possible to make it.

On the other hand, when the first motor 80 and the second motor 82 were connected to both sides of the rotating shaft 70 of the generator 6 and rotated as shown in the configuration of FIG. It was possible to rotate the rotating shaft 70 of the generator 6 with a voltage of 1.5 V and a current measured by the ammeter 88 of 0.345 W of 0.23 A.

Here, when the case of using only the first motor 80 and the case of using two motors of the first motor 80 and the second motor 82 are compared, although the same generator 6 is rotated, There is a difference between 0.66 W and 0.345 W. That is, the input power can be suppressed to about one half. As described above, according to the rotation system 4 in the present embodiment, the two motors of the first motor 80 and the second motor 82 having a rotational force equal to or larger than the rotational torque at the time of steady rotation of the rotation shaft 70 are: Since both ends of the rotating shaft 70 are rotated and the rotational forces of the two motors are combined on the rotating shaft 70, the rotating shaft can be efficiently rotated with less power than when the rotating shaft is rotated by one motor. Can do.

As described above, according to the present invention, it is possible to provide a rotating system that can efficiently rotate the rotating shaft with less power than when the rotating shaft is rotated by one motor.
