Description

Technical Field

[0001] The present invention relates to the technical field of maglev electromagnetic catapult, and particularly to a linear motor for maglev electromagnetic catapult based on hybrid cooling of heat pipes and water channels and powered by a flywheel energy storage system. Background Art

[0002] With the rapid development of aerospace and artificial intelligence technologies, unmanned aerial vehicles (UAVs) are changing all walks of life at an unprecedented speed. Among them, fixed-wing UAVs are widely used in fields such as forest fire prevention due to their high flight speed, fast response, long endurance and other characteristics. As the uses of fixed-wing UAVs become more and more extensive, the requirements for their takeoff and landing methods are also becoming more and more diverse. Currently, the takeoff technologies of fixed-wing UAVs mainly include rocket boost, compressed air boost launch, air drop, runway takeoff, electromagnetic catapult and other forms.

[0003] Solid rocket boost launch does not require runway takeoff. With the thrust of a solid rocket, the UAV takes off directly from the launch rack. Since a solid rocket is used, toxic substances and strong flames will be generated during launch, reducing the launch safety; Compressed air boost launch uses high-pressure gas as the propulsion medium, and the launch process is relatively stable and safe. However, its structure is complex, including equipment such as compressors and gas storage tanks, and the system occupies a large space; Air drop means that a mother aircraft or other delivery platforms carry one or more UAVs to the target airspace and then release the UAVs to achieve takeoff. This method is highly dependent on the air platform and has poor flexibility; Runway takeoff uses the reaction force of high-speed gas generated by the UAV engine as the power to push the UAV to accelerate and take off. This method is highly dependent on the runway and requires good ground conditions.

[0004] Electromagnetic catapult refers to the launch technology that uses electromagnetic force to accelerate an object to a high speed or hypersonic speed. Compared with traditional launch technologies, electromagnetic catapult systems have advantages such as higher launch speed, greater launch kinetic energy, better controllability, and higher energy conversion efficiency. As the core components of electromagnetic catapult devices, linear induction motors and linear permanent magnet synchronous motors have been applied in electromagnetic catapult devices. The secondary structure of a linear induction motor is an aluminum plate, with a simple and reliable structure. However, it has deficiencies such as low power factor and power density; The linear permanent magnet synchronous motor has high efficiency and energy density. However, the secondary needs to place armature windings or permanent magnets, with a complex structure and deficiencies such as low safety and reliability. Currently, most electromagnetic catapult systems are of a wheel-rail structure. The launch stability is limited by track conditions. The wheel-rail structure increases the track friction loss and at the same time increases the secondary maintenance cost.

[0005] In summary, there are still many problems that need to be urgently solved in the current electromagnetic catapult system, which to a certain extent restricts its development and application. Summary of the Invention

[0006] The present invention aims to solve the problems existing in the existing electromagnetic catapults, such as relatively low power factor and power density; although the linear permanent magnet synchronous motor has relatively high efficiency and energy density, the secondary needs to be provided with armature windings or permanent magnets, resulting in a complex structure and relatively low safety and reliability. Currently, most electromagnetic catapult systems are of the wheel-rail structure, and the launch smoothness is restricted by the track conditions. The wheel-rail structure increases the track friction loss and also increases the secondary maintenance cost, etc.

[0007] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0008] Solution 1: The present invention proposes a maglev electromagnetic catapult device based on hybrid cooling of heat pipes and water channels. The maglev electromagnetic catapult device is realized by a stator permanent magnet hybrid excitation maglev linear motor. The device includes a double-sided salient pole mover and double-sided stators. There is an air gap between each side of the mover and the stator of the double-sided salient pole mover and the double-sided stators. A magnetic isolation cooling support unit is arranged between the double-sided stators. The magnetic isolation cooling support unit includes a water channel, a heat conduction fin, and a support structure; both double-sided stators include a stator core, a permanent magnet, an armature winding, and an excitation winding. The stator core includes long teeth and short teeth; the permanent magnet is fixed to the short teeth of the stator core by a surface-mounted structure. The adjacent long teeth of the stator core form a tooth-slot structure. The excitation winding is wound around the long teeth. The excitation winding is cooled by a heat pipe. The evaporation section of the heat pipe is in contact with the excitation winding, and the condensation section is in contact with the magnetic isolation cooling support unit, with an adiabatic section in the middle. The armature winding is a six-phase distributed concentrated ring winding, and the structures of each phase of the armature winding are the same.

[0009] Further, a preferred implementation manner is provided, in which the double-sided salient pole mover adopts a straight slot structure or a skewed slot structure.

[0010] Further, a preferred implementation manner is provided, in which the stator core is made of amorphous alloy material.

[0011] Further, a preferred implementation manner is provided, in which the permanent magnet is a longitudinally segmented structure.

[0012] Further, a preferred implementation manner is provided, in which the permanent magnet is made of neodymium iron boron material.

[0013] Further, a preferred implementation manner is provided, which also includes the step of setting the pole-slot matching mode of the stator permanent magnet hybrid excitation maglev linear motor.

[0014] Further, a preferred implementation manner is provided, in which the pole-slot matching mode of the stator permanent magnet hybrid excitation maglev linear motor is 12 poles for the stator or 23 poles for the mover, and 6 poles for the stator or 10 poles for the mover.

[0015] Further, a preferred embodiment is provided, where the armature winding includes a phase-A armature winding, a phase-B armature winding, a phase-C armature winding, a phase-D armature winding, a phase-E armature winding, and a phase-F armature winding, and steps of calculating the corresponding position relationships of each phase armature winding and the same-phase armature windings are included.

[0016] Further, a preferred embodiment is provided, and the method for calculating the corresponding position relationships of each phase armature winding is as follows:

[0017]

[0018] Where n is an integer τ s is the secondary pole pitch, and the positions corresponding to the same-phase windings satisfy:

[0019] L_AA' = (n + 1)*τ s .

[0020] Further, a preferred embodiment is provided, where the adjacent phase armature windings have a phase difference of 60° in electrical angle.

[0021] The advantages of the present invention are as follows:

[0022] The magnetic levitation electromagnetic catapult device based on hybrid cooling of heat pipes and water channels described in the present invention adopts a stator permanent magnet type structure, and there are neither permanent magnets nor windings on the mover, which ensures the structural strength of the mover while reducing its heat dissipation requirements, improving reliability, and being more suitable for the special working conditions of electromagnetic catapult.

[0023] The permanent magnets described in the present invention adopt a surface-mounted structure, reducing the machining difficulty of the stator.

[0024] The present invention adopts an asymmetric bilateral structure, where the magnetic loads of the upper and lower bilateral stators are different. The levitation force is provided by the difference in the unbalanced magnetic pulling forces of the bilateral stators, and the resultant force in the horizontal direction of the bilateral stators provides the propulsion force for the electromagnetic catapult system.

[0025] The present invention adopts a hybrid excitation structure with good magnetic regulation performance. By controlling the bilateral excitation currents, the bilateral magnetic fields are controlled, and thus the levitation force and thrust of the system are controlled, expanding the application scenarios of the magnetic levitation electromagnetic catapult system for different mass loads.

[0026] The present invention adopts a modular structure, effectively reducing the influence of the lateral end effect of the linear motor. At the same time, physical isolation is achieved between adjacent phase armature windings, increasing the system fault tolerance.

[0027] The armature winding of the present invention adopts a six-phase ring winding, which can effectively reduce the length of the winding end, being more suitable for applications in scenarios with limited longitudinal space. At the same time, the ring winding can effectively utilize the air-gap magnetic field modulation effect, improving the motor power density and thrust density.

[0028] The stator permanent magnet type hybrid excitation maglev linear motor of the present invention can be used as an electromagnetic catapult linear motor with a long primary and a short secondary, or as a maglev vehicle drive motor with a short primary and a long secondary.

[0029] The present invention is also applicable to the cross - field of special motors and engineering thermophysics. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Embodiment Eleven. This embodiment presents an example, and the example is used to explain the above Embodiments One to Ten. The specific example is as follows:

[0053] See Figures 1 to 6 To illustrate this embodiment, this embodiment specifically includes the following steps:

[0054] This embodiment provides a stator permanent magnet type hybrid excitation magnetic levitation linear motor for electromagnetic catapult using a flywheel energy storage system, which is cooled by a hybrid of heat pipes and cooling water channels. The motor includes a double-sided salient pole mover 1 and a double-sided stator 2. There is an air gap between the mover and the stator on each side. Between the double-sided stators is a magnetic isolation cooling support unit 6, which consists of a water channel, heat conducting fins, and a support structure. The double-sided stators each include a stator core 8, a permanent magnet 7, an armature winding 3, and an excitation winding 4. The stator core 8 includes long teeth 9 and short teeth 10. The permanent magnet 7 is fixed to the short teeth 10 of the stator core by a surface-mounted structure. The adjacent long teeth of the stator core 8 form a tooth-slot structure. The excitation winding 4 is wound around the long teeth 9. The excitation winding 4 is cooled by a heat pipe 5. The evaporation section of the heat pipe 5 is in contact with the excitation winding 4, and the condensation section is in contact with the magnetic isolation cooling support structure 6, with an adiabatic section in the middle. The armature winding 3 is a six-phase distributed concentrated ring winding, and the structures of the armature windings 3 of each phase are the same.

[0055] Preferably, the pole-slot matching mode of the motor is that the stator has 12 poles or the mover has 23 poles, and the stator has 6 poles or the mover has 10 poles.

[0056] Preferably, the double-sided movers of the motor adopt a straight slot structure or a skewed slot structure.

[0057] Preferably, the double-sided stator and rotor cores of the motor both adopt a new type of low-loss amorphous alloy material to reduce the eddy current loss of the motor, lower the temperature rise of the motor, and improve the efficiency of the motor.

[0058] Preferably, the permanent magnet 7 of the motor is made of neodymium iron boron material and adopts a longitudinal segmented structure. Specific Embodiment 1:

[0060] This embodiment takes a stator permanent magnet type hybrid excitation magnetic levitation linear motor with a long primary and short secondary structure for electromagnetic catapult, and the pole-slot matching mode is 6 poles for the primary and 11 poles for the secondary as an example. The overall structure is shown as Figure 1 shown, and the electromagnetic structure is shown as Figure 2 shown.

[0061] Refer to Figure 2 . In the motor of the present invention, the double-sided movers are the secondary, and there are 11 mover teeth in total, adopting a salient pole structure. The stator core includes long teeth 9 and short teeth 10. Permanent magnets are surface-mounted on the tops of the short teeth 10. At the same time, the long teeth 9 form a tooth-slot structure and are wound with an excitation winding 4. The armature winding 3 is a ring-shaped concentrated winding, and between the two stators is a magnetic isolation cooling support structure 6.

[0062] Refer to Figure 3, the A-phase armature winding includes a first A-phase sub-armature winding 311 and a second A-phase sub-armature winding 312; the B-phase armature winding includes a first B-phase sub-armature winding 321 and a second B-phase sub-armature winding 322; the C-phase armature winding includes a first C-phase sub-armature winding 331 and a second C-phase sub-armature winding 332; the D-phase armature winding includes a first D-phase sub-armature winding 341 and a second D-phase sub-armature winding 342; the E-phase armature winding includes a first E-phase sub-armature winding 351 and a second E-phase sub-armature winding 352; the F-phase armature winding includes a first F-phase sub-armature winding 361 and a second F-phase sub-armature winding 362, where the corresponding electrical angles of adjacent phase windings differ by 60°.

[0063] The working principle of this motor can be qualitatively analyzed by studying the change of the magnetic flux linkage of the primary coil at different mover positions. The working principle corresponding to one-phase winding is as Figure 4 shown. For the convenience of analysis, the exciting current is set to 0 A. At this time, there is only the permanent magnet magnetic flux under no-load, as Figure 4 (a) shows. At this time, the primary teeth and the secondary teeth overlap. For this phase of the armature winding, the magnetic flux linkage of this winding reaches the positive maximum value at this time. As the mover moves, when it moves to position b, the magnetic flux linkage of the corresponding armature winding is 0. As the mover moves, when it moves to position c, the mover teeth overlap with another pair of stator teeth. At this time, the magnetic flux linkage of the armature winding is the negative maximum value. Finally, when the mover moves to position d, the magnetic flux linkage of the armature winding is 0 again. It can be seen that as the relative movement between the primary and secondary of the motor occurs, the armature winding will be linked with an alternating magnetic flux, thereby generating an alternating back electromotive force. At this time, if a corresponding alternating current is applied, a thrust can be generated.

[0064] Through the design of different magnetic fields on both sides, an asymmetric unilateral magnetic pulling force can be generated. By controlling the magnitude of the exciting current, the magnetic pulling force on each side can be controlled respectively, thereby improving the levitation performance of the present invention and expanding the application scenarios. At the same time, by controlling the exciting current, the magnetic field can be flexibly adjusted, and then the motor thrust can be controlled. The two sides of the motor are controlled separately, which can improve the propulsion performance of the present invention. The magnetic field adjustment method of the present invention is as Figure 5 shown. When the exciting winding 4 is applied with a positive DC exciting current, the change of the magnetic force lines within one cycle is as Figure 5 shown. At this time, it is the magnetizing effect. When a negative DC exciting current is applied, the change of the magnetic force lines is opposite to Figure 5 this, and at this time it is the demagnetizing effect. Specific embodiment 2:

[0066] In this embodiment, a short-primary long-secondary structure for magnetic levitation drive is taken as an example, and the pole-slot matching method is a stator permanent magnet type hybrid excitation magnetic levitation linear motor with 12 poles in the primary and 23 poles in the secondary. Its electromagnetic structure is as Figure 6 shown.

[0067] The basic structure of this embodiment is the same as that of Embodiment 1. The difference between the two is that this embodiment has a short primary and a long secondary structure. The long secondary is fixed as the track, and the primary is stressed to provide the levitation force and driving force of the load. In this embodiment, the primary is composed of two six-phase modular unit motors. The corresponding modules of adjacent phase windings satisfy the above relationship, and the corresponding phase windings of adjacent unit motors satisfy:

[0068]

[0069] where n is a positive integer.

[0070] The spatial positions of the windings of the same phase of this motor correspond to an electrical angle difference of 180°. The magnetic fluxes linked by the windings of the same phase are complementary. For a phase winding, when the linked magnetic flux is 0, the corresponding modules of the two armature coils are in different positions relative to the secondary, and the waveforms of the linked permanent magnetic fluxes cannot completely coincide. For the first phase-A sub-armature winding 311 and the second phase-A sub-armature winding 312, when the primary moves through one electrical cycle, the magnetic flux change corresponding to the first phase-A sub-armature winding 311 is "positive facing - first balance position - negative facing - second balance position - positive facing", and the magnetic flux change corresponding to the second phase-A sub-armature winding 312 is "positive facing - second balance position - negative facing - first balance position - positive facing". It can be seen that the position change of the second phase-A sub-armature winding 312 is half a cycle different from that of the first phase-A sub-armature winding 311 and has the opposite polarity. This design can effectively cancel the even harmonics of the induced electromotive force of the armature coil and improve the sinusoidality of the induced electromotive force of each phase.
