Description

Technical Field

[0001] The present invention belongs to the field of launchers, and in particular relates to a hybrid power catapult, a launching device and a launching method. Background Art

[0002] When performing tasks such as fire extinguishing or rain inducing, an electromagnetic catapult is required to launch the fire extinguishing bomb or rain inducing bomb to the designated location. Electromagnetic catapults are mainly divided into two types: track-type electromagnetic catapults and coil-type electromagnetic catapults.

[0003] In a rail-type electromagnetic catapult, the rail-type electromagnetic catapult includes an electromagnetic barrel, which includes a track. The load (including the object to be launched and the armature) is electrically connected to the track and forms a closed loop with the power supply device. The electromagnetic catapult is also equipped with a control system and a power supply device. When the control system controls the power supply device to provide pulsed DC current, a magnetic field is generated due to the current passing through the track. Since a large DC current also passes through the load, the load will be launched under the action of the Ampere force. In a rail-type electromagnetic catapult, the load is in contact with the track, so there is a problem of track ablation.

[0004] In a coil-type electromagnetic catapult, the coil-type electromagnetic catapult includes an electromagnetic tube, the electromagnetic tube includes a coil, and the electromagnetic catapult is also equipped with a control system and a power supply device; when launching a load, the control system controls the power supply device to provide alternating current to the coil, and the coil with alternating current will generate a changing electromagnetic field, thereby generating an induced current in the armature, and the induced current in the armature interacts with the electromagnetic field generated by the coil (since this process is a prior art, it will not be repeated here), so that the load is launched under the acceleration power provided by the coil. In a coil-type electromagnetic catapult, the coil does not contact the load, so there is no problem of electromagnetic tube being ablated.

[0005] The principles and structures of the above two electromagnetic catapults are completely different. Specifically, the rail-type electromagnetic catapult uses direct current, tracks and Ampere's law to launch the load, while the coil-type electromagnetic catapult uses alternating current, coils and Faraday's law of electromagnetic induction to launch the load.

[0006] As rain clouds are higher and buildings are getting taller, it is necessary to launch the payload higher and farther. In the launch system where the electromagnetic catapult is located, if you want to launch the payload higher and farther, you need to replace the electromagnetic catapult, power supply equipment, and the cable that connects the power supply equipment to the electromagnetic catapult at the same time. There are many devices to replace, which leads to high costs and long construction time.

[0007] In order to overcome the above problems, the Chinese invention patent with application publication number CN111551073A and application publication date 2020.08.18 discloses an electromagnetic composite gun, which includes a gun barrel, a breech block installed in the rear half of the gun barrel, and the rear half of the gun barrel constitutes a gun barrel; the front half of the gun barrel is installed with an upper track and a lower track, and the front half of the gun barrel, the upper track and the lower track constitute an electromagnetic barrel. When launching a load, the breech block is first used to ignite the load, and the high-pressure gunpowder gas generated by the load enters the gun barrel and generates a large chamber pressure in the gun barrel, so that the load moves along the gun barrel to the electromagnetic barrel; when the load moves to the electromagnetic barrel, the upper track and the lower track contact the load and guide the load. At the same time, the control system controls the power supply equipment to supply power to the electromagnetic barrel, and the current flows from the upper track through the load into the lower track. At this time, due to the large pulse current in the load, the load is launched under the action of electromagnetic force.

[0008] However, in the above-mentioned electromagnetic composite artillery, the load needs to slide on the track, and there is a large current on the load and the track itself. On the basis of the current causing the load and the track to heat up, and the friction between the load and the track to generate heat, the track and the load itself will be burned. On this basis, the gunpowder gas will generate a large amount of heat, which will cause the track and the load to be burned very seriously. The electromagnetic composite artillery needs to be repaired or directly replaced with a new one after firing once or several times, and its service life is short. Summary of the invention

[0009] The purpose of the present invention is to provide a hybrid power catapult to solve the technical problem of short service life of existing electromagnetic composite artillery.

[0010] The present invention also aims to provide a launching device to solve the same technical problem as above.

[0011] The present invention also aims to provide a transmitting method to solve the same technical problem as above.

[0012] To achieve the above purpose, the technical solution of the hybrid catapult provided by the present invention is:

[0013] A hybrid power catapult comprises a launching barrel, which is divided into an electromagnetic barrel and a powder barrel. The electromagnetic barrel is located in front of the powder barrel, a breech block is installed at the rear end of the powder barrel, an exciter is installed on the launching barrel for sending a signal to a control device after a load is detected during the launching process, the electromagnetic barrel comprises a coil for externally connecting to a power supply device controlled by the control device, the exciter is located at the rear of the coil, and the coil is used to be powered by the power supply device after the control device receives the signal from the exciter to provide launching power for the load.

[0014] Furthermore, at least one coil is arranged along the axial direction of the launching barrel, and an adjustment rail extending along the axial direction of the launching barrel is fixedly connected to the outside of the launching barrel. The exciter cooperates with the adjustment rail to guide the movement so as to adjust the distance between the exciter and the coil to adapt to different loads with different initial velocities when entering the electromagnetic barrel.

[0015] Furthermore, the igniter is located at the front end of the gunpowder barrel.

[0016] Furthermore, the launching barrel is provided with a barrel support frame, the launching barrel is mounted on the barrel support frame, a connecting plate is also mounted on the barrel support frame, a socket with an aperture matching the outer diameter of the launching barrel is provided on the connecting plate, the rear end of the electromagnetic barrel is inserted into the socket and docked with the front end of the powder barrel inserted into the socket, so as to ensure the sealing of the docking point between the electromagnetic barrel and the powder barrel.

[0017] The beneficial effects of the hybrid catapult of the present invention are as follows: the present invention is a pioneering invention. The load is ignited by the breech block. During launch, the high-temperature and high-pressure gas generated by the ignition of the load forms a chamber pressure in the gunpowder barrel, thereby accelerating the load; when the load moves into the electromagnetic barrel, the coil can be used to accelerate the load again, thereby increasing the range and height of the load. When the coil is used to accelerate the load, the load is never in contact with the coil, so the electromagnetic barrel can be effectively prevented from being ablated, thereby increasing the service life of the hybrid catapult. Compared with the technical solution of using the track to accelerate the load again in the prior art, the difficulty of using the coil to accelerate the load again is that when using the track to accelerate the load, since the track is connected with direct current, the power supply timing of the power supply device is not strictly required, and the power supply can be performed only when the load is on the track; when using the coil to accelerate the load, since the coil is connected with alternating current, the power supply timing needs to be strictly controlled. When the frequency of the alternating current used is 50Hz, the period T of the alternating current is 0.02s, and if the power supply timing differs from the theoretical power supply timing by 0.005-0.01s (0.25T-0.5T), the coil decelerates the load at this time instead of accelerating the load. In order to overcome the above difficulties, an exciter located behind the coil is set on the launch barrel. During the launch process, after the exciter detects the load, the exciter sends a signal to the control device. After receiving the signal, the control device controls the power supply device to power the coil, thereby ensuring that the coil provides the load with launch power instead of launch resistance.

[0018] To achieve the above purpose, the technical solution of the launch device provided by the present invention is:

[0019] A launching device comprises a hybrid power catapult, a control device and a power supply device. The hybrid power catapult comprises a launching barrel, which is divided into an electromagnetic barrel and a powder barrel. The electromagnetic barrel is located in front of the powder barrel, a breech block is installed at the rear end of the powder barrel, an exciter for detecting a load is installed on the launching barrel, the electromagnetic barrel comprises a coil for accelerating the load, the exciter is located behind the coil, during the launching process, the exciter sends a signal to the control device after detecting the load, and the control device controls the power supply device to supply power to the coil according to a set power supply sequence after receiving the signal sent by the exciter, so that the coil provides launching power for the load.

[0020] Furthermore, at least one coil is arranged along the axial direction of the launching barrel, an adjustment rail extending along the axial direction of the launching barrel is fixedly connected to the outside of the launching barrel, and the exciter cooperates with the guiding movement of the adjustment rail to adapt to the different set power supply timings provided by the power supply equipment for loads with different initial velocities when entering the electromagnetic barrel.

[0021] Furthermore, the igniter is located at the front end of the gunpowder barrel.

[0022] Furthermore, the launching barrel is provided with a barrel support frame, the launching barrel is mounted on the barrel support frame, a connecting plate is also mounted on the barrel support frame, a socket with an aperture matching the outer diameter of the launching barrel is provided on the connecting plate, the rear end of the electromagnetic barrel is inserted into the socket and docked with the front end of the powder barrel inserted into the socket, so as to ensure the sealing of the docking point between the electromagnetic barrel and the powder barrel.

[0023] The beneficial effects of the launch device of the present invention are as follows: the present invention is a pioneering invention. The load is ignited by the breech block. During the launch, the high-temperature and high-pressure gas generated by the ignition of the load forms a chamber pressure in the gunpowder barrel, thereby accelerating the load; when the load moves into the electromagnetic barrel, the coil can be used to accelerate the load again, thereby increasing the range and height of the load. When the coil is used to accelerate the load, the load is never in contact with the coil, so the electromagnetic barrel can be effectively prevented from being ablated, thereby increasing the service life of the hybrid catapult. Compared with the technical solution of accelerating the load again by using the track in the prior art, when the coil is used to accelerate the load again, the difficulty is that when the track is used to accelerate the load, since the track is connected with a direct current, the power supply timing of the power supply equipment is not strictly required, and the load only needs to be powered when it is on the track; when the coil is used to accelerate the load, since the coil is connected with an alternating current, the power supply timing needs to be strictly controlled. To overcome the above difficulties, an energizer is provided behind the coil on the launch barrel. During the launch process, after the energizer detects the load, the energizer sends a signal to the control device. After receiving the signal, the control device controls the power supply device to power the coil, thereby ensuring that the coil provides the load with launching power.

[0024] To achieve the above purpose, the technical solution of the transmitting method provided by the present invention is:

[0025] A launching method, firstly, uses a breech block to ignite a load in a gunpowder barrel of a launching barrel, when the load reaches an igniter arranged on the launching barrel, the igniter sends a signal to a control device, after receiving the signal sent by the igniter, the control device controls a power supply device to supply power to a coil, so that the coil provides launching power for the load.

[0026] Furthermore, at least one coil is arranged along the axial direction of the launch barrel. For a load with a greater initial velocity when entering the electromagnetic barrel, the distance between the excitation tube and the coil is greater, and the position of the load is further back when the coil starts to be energized. At the same time, the rear end of the armature in the load is farther from the middle position of the rearmost coil, so as to increase the range and shooting height of the load.

[0027] The beneficial effects of the launching method of the present invention are as follows: the present invention is a pioneering invention. The load is ignited by the breech block. During the launch, the high-temperature and high-pressure gas generated by the ignition of the load forms a chamber pressure in the gunpowder barrel, thereby accelerating the load; when the load moves into the electromagnetic barrel, the coil can be used to accelerate the load again, thereby increasing the range and shooting height of the load. When the coil is used to accelerate the load, the load is never in contact with the coil, so the electromagnetic barrel can be effectively prevented from being ablated, thereby increasing the service life of the hybrid catapult. Compared with the technical solution of accelerating the load again by using the track in the prior art, when the coil is used to accelerate the load again, the difficulty is that when the track is used to accelerate the load, since the track is connected with a direct current, the power supply timing of the power supply equipment is not strictly required, and the load only needs to be powered when it is on the track; when the coil is used to accelerate the load, since the coil is connected with an alternating current, the power supply timing needs to be strictly controlled. To overcome the above difficulties, during the transmission process, an exciter is used to detect the load. After the exciter detects the load, the exciter sends a signal to the control device. After receiving the signal, the control device controls the power supply device to power the coil, thereby ensuring that the coil provides the load with transmission power.

[0038] In order to solve the problems in the background technology, the core inventive concept of the present invention is: using the coil to accelerate the load again, so as to avoid the electromagnetic barrel from being ablated and to increase the life of the hybrid catapult. At the same time, during the launch process, an exciter is used to detect the load. When the exciter detects the load, the exciter sends a signal to the control device. After the control device receives the signal sent by the exciter, the control device controls the power supply device to supply power to the coil, so as to ensure that the coil provides the launch power for the load.

[0039] The present invention is further described in detail below in conjunction with embodiments.

[0040] The specific embodiment of the hybrid power catapult provided by the present invention is as follows:

[0041] like Figure 1-6 As shown, the hybrid catapult includes a barrel support frame 3 and a launching barrel installed on the barrel support frame 3. The launching barrel is divided into an electromagnetic barrel 1 and a gunpowder barrel 2. The electromagnetic barrel 1 is located in front of the gunpowder barrel 2. A breech block 4 for igniting a load 5 is installed at the rear end of the gunpowder barrel 2. An exciter 10 for sending a signal to a control device after detecting the load 5 during the launching process is installed on the launching barrel. The electromagnetic barrel 1 includes a coil 101 for externally connecting a power supply device controlled by the control device. The exciter 10 is located behind the coil 101. The coil 101 is used to be powered by the power supply device after the control device receives the signal from the exciter 10 to provide launching power for the load 5.

[0042] Among them, the exciter 10 can be an inductive exciter, such as a photoelectric sensor for detecting whether an object has reached a specified position; or, the exciter 10 can be a contact exciter, for example, the exciter 10 has a telescopic pin that can be extended and retracted along the radial direction of the launch barrel, one end of the telescopic pin extends into the launch barrel, and the telescopic pin has a guiding slope on the side facing the load 5. After the load 5 contacts the telescopic pin, since the mass of the load 5 is much greater than the mass of the telescopic pin and the telescopic pin has a guiding slope, the telescopic pin will leave the launch barrel and send a signal to the control device. The power supply device and the control device are existing products, but the parameters set when launching different loads 5 are different, which will not be repeated here.

[0043] The launching device includes a catapult, a power supply device and a control device. After the above-mentioned hybrid power catapult is applied to the launching device, during the launching process, the exciter 10 sends a signal to the control device after detecting the load 5. After receiving the signal sent by the exciter 10, the control device controls the power supply device to power the coil 101 according to the set power supply timing, so that the coil 101 provides launching power for the load 5.

[0044] The load 5 is ignited by the breech block 4. During the launching process, the high-temperature and high-pressure gas generated by the ignition of the load 5 forms a chamber pressure in the gunpowder barrel 2, thereby ejecting the load 5. When the load 5 moves into the electromagnetic barrel 1, the coil 101 can be used to accelerate the load 5, thereby increasing the range and height of the load 5. When the coil 101 is used to accelerate the load 5, the load 5 is never in contact with the coil 101, so the electromagnetic barrel 1 can be effectively prevented from being ablated, thereby increasing the service life of the hybrid catapult. Compared with the technical solution of using the track to accelerate the load 5 again in the prior art, the difficulty of using the coil 101 to accelerate the load 5 is: when using the track to accelerate the load 5, since the track carries a direct current, the power supply timing of the power supply equipment is not strict, and the load 5 only needs to be powered when it is on the track; when using the coil 101 to accelerate the load 5, since the coil 101 carries an alternating current, the power supply timing needs to be strictly controlled. When the frequency of the alternating current used is 50Hz, the period T of the alternating current is 0.02s, if the power supply timing differs from the theoretical power supply timing by 0.005-0.01s (0.25T-0.5T), the coil 101 decelerates the load 5 instead of accelerating the load 5. In order to overcome the above difficulties, an exciter 10 located behind the coil 101 is provided on the launching barrel. During the launching process, after the exciter 10 detects the load 5, the exciter 10 sends a signal to the control device. After receiving the signal, the control device controls the power supply device to supply power to the coil 101, thereby ensuring that the coil 101 provides the load 5 with launching power instead of launching resistance.

[0045] Reference Figure 1-6 As shown, in order to adapt to different loads 5, as a specific implementation, an adjustment rail 11 extending along the axial direction of the launch barrel is fixedly connected to the outside of the launch barrel, and the exciter 10 is guided and moved in coordination with the adjustment rail 11 to adjust the distance between the exciter 10 and the coil 101 to adapt to different loads 5 with different initial velocities when entering the electromagnetic barrel 1. It also takes a certain amount of time for the exciter 10 to transmit the signal to the control device, and the control device to control the power supply device. The faster the speed of the load 5, the longer the distance the load 5 moves during this period of time, and therefore, the distance between the exciter 10 and the coil 101 is also greater.

[0046] During specific adjustments, in order to increase the range and height of the load 5, the greater the initial velocity of the load 5 entering the electromagnetic tube 1, the further back the position of the load 5 is when the coil 101 starts to be energized, and the farther the rear end of the armature in the load 5 is from the middle position of the rearmost coil 101.

[0047] The number of coils 101 can be one, two or more, which is not limited here. It is prior art to use different numbers of coils 101 to launch the same load 5 with an initial velocity of 0. The difference between this specific embodiment and the prior art is only that in this specific embodiment, the initial velocity of the load 5 launched by the coil 101 is not 0.

[0048] In the existing coil-type electromagnetic catapult, since the initial velocity of the load is 0, when the rear end of the armature in the load is flush with the middle position of the rearmost coil, the load has the longest range and the highest shooting height. In a technical solution of the present embodiment, when the power supply device starts to supply power, the rear end of the armature in the load 5 is flush with the middle position of the rearmost coil 101. This solution can also improve the range and shooting height of the load 5. However, after many tests, it was found that if the power supply device supplies power to the coil 101 before the rear end of the armature in the load 5 reaches the middle position of the rearmost coil 101, the range of the load 5 is longer and the shooting height is higher. After research, the specific reasons are found to be as follows:

[0049] In the very short time when the power supply device just starts to supply power to the coil 101, the coil 101 just starts to generate an induced magnetic field, and the armature just starts to generate an induced current. At this time, the force applied by the coil 101 to the load 5 is relatively small. After a very short time, the coil 101 applies a relatively large force to the load 5. When the initial velocity of the load 5 is 0, there is basically no relative displacement between the load 5 and the coil 101. Therefore, this period of time can be ignored, and the length of the coil 101 accelerating the load 5 is still approximately half of the axial length of the coil 101. For example, Figure 7Selected from "Study on the Acceleration Characteristics of Three Coaxial Induction Coil Transmitters (Electrical Technology, Issue S1, 2010, Authors Zhao Keyi, Zhang Qianfan, Li Zhiyuan, Cheng Shukang)" Figure 5 A curve that represents the relationship between the displacement of the armature and time. Figure 7 It can be seen that when the initial speed of the load is 0, in a very short time (also called preheating time, warm-up time, etc., the very short time t can be 0.0001s, and the value of t is as long as it is Figure 7 The horizontal coordinate corresponding to the midpoint A can be small) The relative displacement between the load and the coil can be ignored. Figure 8 For the above article Figure 4 A curve that represents the relationship between the acceleration force (Accelerative Force) of the armature and time (Time). Figure 8 It can be seen that the force exerted by the coil on the load is small in a very short time. This very short time is affected by factors such as the load mass and the coil current. This part is the existing technology and will not be repeated here.

[0050] Reference Figure 1-6 As shown, after the load 5 is accelerated to a certain initial velocity in the gunpowder barrel 2, the displacement between the load 5 and the coil 101 cannot be ignored in this extremely short time. If the coil 101 is energized only when the rear end of the armature in the load 5 is flush with the middle position of the coil 101, a large displacement has occurred between the load 5 and the coil 101 in this extremely short time, resulting in a significant shortening of the length of the coil 101 accelerating the load 5, thereby resulting in a shorter range and a lower shooting height of the load 5. Therefore, it is necessary to make the rear end of the armature in the load 5 have a set distance from the middle position of the rearmost coil 101 (the set distance can be a range or a preferred determined value), and the greater the initial velocity of the load 5 entering the electromagnetic barrel 1, the farther the rear end of the armature in the load 5 is from the middle position of the rearmost coil 101. Accordingly, since the exciter 10 sends a signal to the control device, it takes a certain amount of time for the control device to control the power supply device after receiving the signal, so the greater the initial velocity of the load 5 entering the electromagnetic tube 1, the greater the distance between the exciter 10 and the coil 101. At this time, the load 5 is first subjected to resistance in this extremely short time, and then to power, but the power is much greater than the resistance, so the launch speed, range and height of the load 5 can be improved.

[0051] To simplify the structure, refer to Figure 1-6As shown, as a specific embodiment, the activator 10 is located at the front end of the gunpowder barrel 2, and the structure is simple. However, in other specific embodiments, the activator 10 can also be set at the rear end of the electromagnetic barrel 1. In this case, the activator 10 is still located behind the coil 101. When the initial velocity of the load 5 entering the electromagnetic barrel 1 is large, the electromagnetic barrel 1 is long, thereby causing the entire launch barrel to be long.

[0052] In order to facilitate the manufacture of the launch tube, Figure 1-6 As shown, the launching barrel is a split structure, and a connecting plate 9 is also installed on the barrel support frame 3. The connecting plate 9 is provided with a socket whose aperture is adapted to the outer diameter of the launching barrel. The rear end of the electromagnetic barrel 1 is inserted into the socket and docked with the front end of the powder barrel 2 inserted into the socket to ensure the sealing of the docking point between the electromagnetic barrel 1 and the powder barrel 2. Two mounting plates 31 for mounting the coil 101 are also provided on the barrel support frame 3. The two mounting plates 31 mount and fix the coil 101 between the two mounting plates 31. The structure is simple, and the electromagnetic barrel 1 and the powder barrel 2 can be manufactured separately, which is convenient for the processing and manufacturing of the launching barrel.

[0053] However, in other specific embodiments, refer to Figure 1-6 As shown, a gun barrel may be manufactured first, and the coil 101 is wound around the front half of the gun barrel to form the electromagnetic barrel 1, and the rear half of the gun barrel constitutes the powder barrel 2.

[0054] In order to adjust the launch elevation angle, Figure 1-6 As shown, the hybrid catapult also includes a pitch adjustment seat 7, the barrel support frame 3 is rotatably mounted on the pitch adjustment seat 7, and the output end of the pitch adjustment motor 8 is transmission-connected with the barrel support frame 3, so that the pitch angle of the barrel support frame 3 is adjusted and positioned by the pitch adjustment motor 8, thereby adjusting and positioning the pitch angle of the launch barrel. Figure 1-6 As shown, the front end of the barrel support frame 3 is also provided with a cable groove 6 for accommodating the portion of the cable electrically connected to the coil 101 .

[0055] The specific embodiment of the transmitting device provided by the present invention is as follows:

[0056] Reference Figure 1-6 As shown, the launching device includes a hybrid power catapult, a control device and a power supply device. The hybrid power catapult is any one of the specific embodiments of the hybrid power catapult provided by the present invention, which will not be described in detail here. During the launching process, the exciter 10 sends a signal to the control device after detecting the load 5. After receiving the signal sent by the exciter 10, the control device controls the power supply device to power the coil 101 according to the set power supply sequence, so that the coil 101 provides launching power for the load 5. When the launching barrel has an adjustment rail 11, the power supply device can provide different set power supply sequences for loads 5 with different initial velocities when entering the electromagnetic barrel 1.

[0057] The specific embodiment of the transmitting method provided by the present invention is as follows:

[0058] Reference Figure 1-6 As shown, the launching method of the present invention is: first, the load 5 in the gunpowder barrel 2 of the launching barrel is ignited by using the breech block 4. When the load 5 reaches the igniter 10 set on the launching barrel, the igniter 10 sends a signal to the control device. After receiving the signal sent by the igniter 10, the control device controls the power supply device to supply power to the coil 101, so that the coil 101 provides launching power for the load 5.

[0059] The launching method of the present invention can be implemented by utilizing the hybrid power catapult and launching device provided by the present invention.

[0060] Reference Figure 1-6 As shown, in order to further improve the range and height of the load 5, at least one coil 101 is arranged along the axial direction of the launch barrel. For the load 5 with a greater initial velocity when entering the electromagnetic barrel 1, the distance between the excitation tube and the coil 101 is greater, and the position of the load 5 is further back when the coil 101 starts to be energized, and at the same time, the rear end of the armature in the load 5 is farther from the middle position of the rearmost coil 101.

[0061] The above-mentioned launching method can be realized by using the hybrid power catapult and launching device provided by the present invention which contain the adjusting guide rail 11.

[0062] In particular, refer to Figure 1-6 As shown, the above-mentioned launching method can also be implemented by using a hybrid catapult and a launching device that do not contain an adjustment rail 11. Specifically, the exciter 10 is fixedly arranged on the launching barrel. For the load 5 with a large initial velocity when entering the electromagnetic barrel 1, the control device directly controls the power supply device to supply power to the coil 101 after receiving the signal of the exciter 10, so that the position of the load 5 is relatively backward when the coil 101 starts to be energized, and the rear end of the armature in the load 5 is far from the middle position of the rearmost coil 101; for the load 5 with a small initial velocity when entering the electromagnetic barrel 1, the control device waits for a set time after receiving the signal of the exciter 10 and then controls the power supply device to supply power to the coil 101, so that the position of the load 5 is relatively forward when the coil 101 starts to be energized, and the rear end of the armature in the load 5 is close to the middle position of the rearmost coil 101.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
