Description

Technical Field

[0001] This application relates to the field of equipment control technology, and in particular to a control method, apparatus and readable storage medium for a winding machine. Background Technology

[0002] A winding machine is a production equipment for iron core coils. The products are mainly used in metering and protection instruments, leakage current protectors, electronic components and other fields. The core device of the winding machine to perform the winding action is the winding motor. However, at present, the production efficiency of the winding machine is greatly affected by the operator's skill level and condition. Therefore, the existing control methods of the winding machine have technical problems such as low production efficiency. Summary of the Invention

[0003] This application provides a control method, apparatus, and readable storage medium for a winding machine to solve technical problems such as low production efficiency in the prior art.

[0004] A first aspect of this application provides a control method for a winding machine, the winding machine including a counter, a photoelectric switch, and a winding motor, wherein the counter and the photoelectric switch are connected, and the photoelectric switch and the winding motor are connected, the method comprising:

[0005] Before the winding machine winds the iron core, determine the number of the first winding turns for the iron core; Based on the first number of winding turns, determine the corresponding second number of winding turns for the iron core, where the second number of winding turns is less than the first number of winding turns; During the process of controlling the winding motor to drive the iron core to rotate at the first speed to wind the coil on the iron core, the number of coil turns wound on the iron core is detected by controlling the counter and photoelectric switch. When the number of coil turns wound on the iron core is detected to be greater than or equal to the second number of winding turns, the winding motor is controlled to drive the iron core to rotate at a second speed, which is less than the first speed. If the number of coil turns wound on the iron core is detected to be greater than or equal to the first number of turns, the winding motor is controlled to stop working.

[0006] The control method of the winding machine in this embodiment can accurately detect the number of coil turns wound on the iron core in real time through a counter and photoelectric switch, saving a lot of labor costs and improving the counting efficiency and base accuracy of the coils on the iron core.

[0007] In addition, if the second number of winding turns is determined to be less than the first number of winding turns, the winding motor first winds the coil on the iron core at the first speed. By monitoring the number of coil turns already wound on the iron core, it is first determined whether the number of coil turns on the iron core is greater than or equal to the second number of winding turns, and then the winding progress of the iron core is determined. When it is detected that the number of coil turns on the iron core is greater than or equal to the second number of winding turns, it means that the number of coil turns on the iron core is close to the set number. Then the number of unwound turns is relatively small. Therefore, the speed of the winding machine is controlled to be reduced from the first speed to the second speed, so that the winding motor runs at a low speed. After the speed is reduced, it is easier to detect the number of winding turns, the detection accuracy is higher, and the set number of turns can be wound more accurately when it is close to the set number of turns, avoiding too few or too many turns. It can also ensure the operation stability of the winding motor and improve the control flexibility of the winding motor.

[0008] When the number of coil turns in the iron core is greater than or equal to the number of turns in the first winding, the winding motor is controlled to stop working. By real-time monitoring, setting two thresholds, and segmented speed control, the precise number of coil turns in the iron core can be achieved, thus improving the control accuracy of the winding motor.

[0009] Real-time detection of the number of coil turns in the iron core during winding machine operation can eliminate the coil verification step after the iron core coil is produced, shortening the production steps of the winding machine and thus improving the production efficiency of the winding machine.

[0010] A second aspect of this application provides a control device for a winding machine. The winding machine includes a counter, a photoelectric switch, and a winding motor. The counter and the photoelectric switch are connected, and the photoelectric switch and the winding motor are connected. The device includes: The first processing unit is used to determine the first number of winding turns of the iron core before the winding machine winds the iron core into a coil; The second processing unit is used to determine the second number of winding turns corresponding to the iron core based on the first number of winding turns, wherein the second number of winding turns is less than the first number of winding turns; The first control unit is used to detect the number of coil turns wound on the iron core by controlling the winding motor to drive the iron core to rotate at a first speed to wind the iron core into a coil. The second control unit is used to control the winding motor to drive the iron core to rotate at a second speed when the number of coil turns wound on the iron core is detected to be greater than or equal to the second number of winding turns. The second speed is less than the first speed. The third control unit is used to control the winding motor to stop working when it detects that the number of coil turns wound on the iron core is greater than or equal to the first number of winding turns.

[0011] The control device of the winding machine in this embodiment can accurately detect the number of coil turns wound on the iron core in real time through a counter and photoelectric switch, saving a lot of labor costs and improving the counting efficiency and base accuracy of the coils on the iron core.

[0012] In addition, the first and second winding turns are determined for the iron core respectively. When the number of coil turns of the iron core is greater than or equal to the second winding turn, the speed of the winding motor is adjusted from the first speed to the second speed, so that the winding motor runs at a low speed, ensuring the operation stability of the winding motor and improving the control flexibility of the winding motor.

[0013] When the number of coil turns in the iron core is greater than or equal to the number of turns in the first winding, the winding motor is controlled to stop working. Based on the precise number of coil turns in the iron core, the control accuracy of the winding motor is improved.

[0014] Real-time detection of the number of coil turns in the iron core during winding machine operation can eliminate the coil verification step after the iron core coil is produced, shortening the production steps of the winding machine and thus improving the production efficiency of the winding machine.

The memory stores a computer program, which, when executed by the processor, implements the steps of the winding machine control method as described in any of the above embodiments. Therefore, this control device for a winding machine possesses all the beneficial effects of the winding machine control method in any of the above embodiments, and will not be elaborated further here.

[0021] In some embodiments, such as Figure 1 As shown, an embodiment of this application provides a control method for a winding machine, including: Step S101: Before the winding machine winds the iron core, determine the number of the first winding turns corresponding to the iron core; Step S102: Determine the second number of winding turns corresponding to the iron core based on the first number of winding turns, wherein the second number of winding turns is less than the first number of winding turns; Step S103: During the process of controlling the winding motor to drive the iron core to rotate at the first speed to wind the iron core with coil, the number of coil turns wound on the iron core is detected by controlling the counter and photoelectric switch. Step S104: When it is detected that the number of coil turns wound on the iron core is greater than or equal to the second number of winding turns, the winding motor is controlled to drive the iron core to rotate at the second speed, which is less than the first speed. Step S105: If the number of coil turns wound on the iron core is detected to be greater than or equal to the first number of winding turns, the winding motor is controlled to stop working.

[0022] In this embodiment, a control method for a winding machine is proposed. The winding machine is a core coil production equipment used to uniformly and tightly wind wire or strip materials onto an iron core to form a coil according to specific process requirements. The winding machine is mainly used in the fields of metering and protection instruments, leakage current protectors, and electronic components.

[0023] The winding machine includes a counter, a photoelectric switch, and a winding motor. The counter and the photoelectric switch are connected, and the photoelectric switch and the winding motor are connected. The winding motor is used to drive the iron core to rotate in order to wind the iron core into a coil. The photoelectric switch is used to send a signal to the counter when the winding motor rotates. The counter is used to receive the signal sent by the photoelectric switch and then determine the number of rotations of the winding motor.

[0024] For example, the winding motor is the core power component in the winding machine, mainly used to drive the winding shaft to rotate, so as to achieve uniform, high-speed and high-precision winding of linear or strip materials (such as lithium battery electrodes, separators, yarns, metal wires, etc.).

[0025] For example, a counter is a digital circuit or electronic device used to record and count the number of input pulses, and it is widely used in many fields such as electronics, industrial control, education and daily life.

[0026] For example, the counter has a high-speed counting function. Utilizing this function, which allows continuous counting until a preset count value is reached, the counter can simultaneously acquire pulse feedback signals from the photoelectric switch at high speed, execute control logic, and sequentially output deceleration and stop signals to the frequency converter to achieve precise positioning and stopping. At that time, the counter will also automatically store the counting result and start counting again. The total value can be obtained and reset with just a simple button press.

[0027] For example, a photoelectric switch is a non-contact sensor that uses the blocking or reflection of a light beam to detect the presence, position, and motion state of an object. It is widely used in industrial automation, logistics sorting, and security protection. Photoelectric switches are characterized by fast response speed, long lifespan, and strong anti-interference ability.

[0028] For example, a photoelectric switch may include a photoelectric sensor that utilizes the principle of blocking the emission of a light beam to achieve extremely high detection accuracy.

[0029] For example, a positioning block is installed on the end face of the winding shaft of the winding motor, and the detection distance between the positioning block and the photoelectric switch is adjusted to ensure that the photoelectric switch can stably trigger a signal once every time the winding motor rotates. This is also an important guarantee for the response frequency and detection accuracy of the photoelectric switch.

[0030] Before the winding machine winds the iron core into coils, the first winding number of turns corresponding to the iron core is determined, wherein the first winding number of turns is the preset winding number of turns of the iron core.

[0031] For example, the first number of turns is the set number of coil turns of the iron core. By setting the number of turns of the iron core as the first number of turns, it can be determined that the iron core coil has been completed when the number of coil turns on the iron core reaches the first number of turns.

[0032] For example, setting a first number of winding turns can ensure that the actual coil of the iron core coil meets the number of turns requirement, thereby ensuring that the iron core coil produced by the winding machine meets the product requirements, and at the same time ensuring that the iron core coil produced by the winding machine can meet different application scenarios, avoiding the defect of insufficient magnetic force in the iron core coil produced by the winding machine.

[0033] For example, when the iron core is used in an electromagnetic relay, the initial winding count is typically between 500 and 2000 turns. Using finer enameled wire in the iron core and a higher number of turns reduces the operating current, making it suitable for long-term energized operation. For example, when the iron core is used in an automotive ignition system or a high-voltage generator, the first number of winding turns is typically between 15,000 and 25,000.

[0034] For example, if the real-time number of coil turns of the iron core is equal to the first number of winding turns, it indicates that the coil winding process of the iron core has been completed.

[0035] Based on the first number of winding turns, determine the corresponding second number of winding turns for the iron core, wherein the second number of winding turns is less than the first number of winding turns, and the second number of winding turns is the preset number of winding turns for the iron core.

[0036] For example, the second number of winding turns is the critical number of winding turns for the iron core, and the second number of winding turns is less than the first number of winding turns. When the number of coil turns on the iron core reaches the second number of winding turns, it can be determined that the iron core coil is close to being completed. After continuing to wind the coil for a while, the production of the iron core coil can be completed. At this stage, the speed of the winding motor needs to be adjusted from the first speed to the second speed, so that the winding motor operates at a low speed, which improves the control flexibility of the winding motor.

[0037] After the winding machine is started, the winding motor is controlled to drive the iron core to rotate at a first speed in order to wind the iron core into a coil. The first speed is the preset rotation speed of the winding motor.

[0038] For example, the first rotational speed can be determined based on the mass or size of the iron core. The larger the mass or size of the iron core, the smaller the first rotational speed, which reduces the vibration amplitude of the winding motor and improves the operating stability of the winding motor.

[0039] During the rotation of the winding motor, a counter and a photoelectric switch are used to detect the number of coil turns wound on the iron core. The number of coil turns is the number of turns of the coil on the iron core.

[0040] For example, the rotation of the winding motor is detected by a photoelectric switch. For each rotation of the winding motor, the photoelectric switch can send a signal to the counter. At the same time, the counter determines the number of rotations of the winding motor by receiving the signal sent by the photoelectric switch, and thus determines the number of coil turns wound on the iron core, ensuring the accuracy of the coil turn count. In addition, detecting the number of coil turns wound on the iron core by using a counter and a photoelectric switch can save a lot of labor costs and improve the counting efficiency of the coils on the iron core.

[0041] If the number of coil turns wound on the iron core is detected to be greater than or equal to the second number of winding turns, it indicates that the iron core coil winding process is nearing completion. The winding motor is then controlled to drive the iron core to rotate at the second speed, where the second speed is less than the first speed.

[0042] For example, if the real-time number of coil turns of the iron core is greater than or equal to the second number of winding turns, it indicates that the coil winding process of the iron core is nearing completion, and the speed of the winding motor needs to be reduced.

[0043] For example, when the number of coil turns wound on the iron core is detected to be greater than or equal to the second number of winding turns, the winding motor is controlled to decelerate so that the winding motor drives the iron core to rotate at the second speed.

[0044] For example, when it is detected that the number of coil turns wound on the iron core is greater than or equal to the second number of winding turns, the winding motor is controlled to decelerate, which improves the control flexibility of the winding motor and at the same time improves the control accuracy of the winding motor.

[0045] If the number of coil turns wound on the iron core is detected to be greater than or equal to the first number of turns, it indicates that the iron core coil winding process has been completed, and the winding motor is controlled to stop working.

[0046] For example, when the real-time number of coil turns in the iron core is greater than or equal to the first number of winding turns, the winding motor is stopped in time to ensure that the winding machine can stop accurately and in a timely manner, thereby improving the control accuracy of the winding machine and ensuring the accuracy of the coil products.

[0047] It should be noted that this embodiment, through a counter and photoelectric switch, can accurately detect the number of coil turns wound on the iron core, saving significant labor costs and improving the counting efficiency of the coils on the iron core. Simultaneously, by determining the first and second number of coil turns for the iron core, and by precisely controlling the winding motor when the number of coil turns on the iron core is greater than or equal to the second number of coil turns and when the number of coil turns on the iron core is greater than or equal to the first number of coil turns, the operational stability of the winding motor is ensured, and the control accuracy of the winding motor is improved.

[0048] The control method of the winding machine in this embodiment sets a counter and a photoelectric switch on the winding motor. The counter and photoelectric switch accurately detect the number of coil turns wound on the iron core, ensuring the accuracy of the coil turn count. The winding motor is then precisely controlled based on the coil turn count, which shortens the production process of the winding machine and improves its production efficiency.

[0049] In some embodiments, this application provides a control method for a winding machine, which determines the first number of winding turns corresponding to the iron core, including: Obtain the dimensional parameters and material properties of the iron core; Determine the operating frequency range of the iron core based on the material properties parameters; The number of the first winding turns is determined based on the dimensional parameters, material properties, and operating frequency range.

[0050] In this embodiment, the size parameters and material property parameters of the iron core are obtained, wherein the size parameters represent the specific dimensions of the iron core, and the material property parameters represent the material type and material properties of the iron core.

[0051] The dimensional parameters include the length and cross-sectional area of ​​the iron core.

[0052] The length of the iron core is directly related to the magnetic circuit length of the iron core. The magnetic circuit length is the average path length of the magnetic lines of force in the iron core, which affects the magnetic reluctance and the excitation current.

[0053] The cross-sectional area is the effective cross-sectional area of ​​the central column of the iron core, which determines the magnetic flux density and inductance.

[0054] For example, when the core is cylindrical, the dimensional parameters may include the length and diameter of the core.

[0055] For example, when the core is cuboid in shape, the dimensional parameters may include the length, width, and height of the core.

[0056] The material properties of the iron core directly affect the efficiency, temperature rise, and power density of electromagnetic equipment. Key parameters include permeability, saturation flux density, iron loss (hysteresis and eddy current loss), resistivity, and machinability. Specifically: Permeability is an indicator that measures a material's ability to conduct magnetic energy. It is divided into initial permeability and maximum permeability. High permeability can reduce excitation current and improve energy conversion efficiency.

[0057] Saturation magnetic flux density, the maximum magnetic flux density that a material can withstand, determines the upper limit of the device's power and volume.

[0058] Core losses, including hysteresis losses and eddy current losses, directly affect the product's temperature rise and energy efficiency.

[0059] Resistivity: High resistivity can suppress eddy currents and reduce eddy current losses.

[0060] Based on the material properties, the operating frequency range of the iron core is determined, where the operating frequency range is the frequency range in which the iron core can generate effective magnetic force.

[0061] For example, when the coil on the iron core is energized, the operating frequency range of the iron core needs to be limited to ensure that the iron core generates sufficient magnetic force.

[0062] For example, the operating frequency range of the iron core is affected by the number of turns of the coil on the iron core. Therefore, when the operating frequency range of the iron core is determined, it is necessary to adjust the number of turns of the coil on the iron core.

[0063] For example, the operating frequency range of the iron core is mainly determined by its material properties, and different materials are suitable for different frequency bands.

[0064] Silicon steel sheet cores operate in the frequency range of 50Hz to 1000Hz and are mainly used in power frequency transformers, power distribution systems, and motor cores. They are suitable for low-frequency, high-power applications, such as 50 / 60Hz power grid equipment. Because eddy current losses increase sharply with frequency, they are generally not used in high-frequency applications.

[0065] Ferrite cores operate in the frequency range of 10kHz to 1MHz, with some high-performance models reaching over 2MHz. Their main applications include switching power supplies, high-frequency transformers, RF inductors, and filters. The high resistivity of ferrite cores effectively suppresses eddy currents, making them suitable for high-frequency, low-loss operation.

[0066] The operating frequency range of amorphous alloy iron core is 50Hz to 50kHz. Its main applications include: high-efficiency distribution transformers, medium-frequency power supplies, and high-power switching power supply reactors. The iron loss of amorphous alloy iron core is only 1 / 3 to 1 / 5 of that of silicon steel sheets, resulting in significant energy-saving effects. It is suitable for medium and high frequency power equipment.

[0067] The operating frequency range of nanocrystalline iron core is 1kHz to 100kHz. Its main applications include on-board chargers, motor controllers, and inductors. Nanocrystalline iron core combines high saturation magnetic flux density with low high-frequency loss.

[0068] The metal powder core operates in the frequency range of 50Hz to 5MHz and is mainly used in power factor correction, energy storage inductors, and DC-DC converters. The metal powder core has a distributed air gap, strong anti-DC bias magnetization capability, and is suitable for wide-frequency stable operation.

[0069] The number of the first winding turns is determined based on the dimensional parameters, material properties, and operating frequency range.

[0070] For example, the first number of winding turns is directly affected by dimensional parameters, material property parameters, and operating frequency range. The first number of winding turns can be determined based on the dimensional parameters, material property parameters, and operating frequency range. Specifically, the larger the operating frequency range, the smaller the first number of winding turns; the larger the dimensional parameters, the smaller the first number of winding turns; the larger the permeability in the material property parameters, the smaller the first number of winding turns; and the larger the magnetic reluctance in the material property parameters, the larger the first number of winding turns.

[0071] In some embodiments, this application provides a control method for a winding machine, which determines a second number of winding turns corresponding to the iron core based on a first number of winding turns, including: Obtain the preset ratio of the iron core, which represents the ratio between the number of first winding turns and the number of second winding turns; The second number of winding turns is obtained by calculating the product of the first number of winding turns and the preset ratio.

[0072] In this embodiment, a preset ratio of the iron core is obtained, wherein the preset ratio represents the ratio between the first number of winding turns and the second number of winding turns.

[0073] For example, the preset ratio is a ratio less than 1.

[0074] For example, the preset ratio can be specifically 85%, 90%, or 95%.

[0075] The second number of winding turns is obtained by calculating the product of the first number of winding turns and the preset ratio.

[0076] For example, the second number of winding turns = 95% × the first number of winding turns.

[0077] In some embodiments, this application provides a control method for a winding machine, wherein a photoelectric switch outputs a pulse signal for each revolution of the winding motor, and the number of coil turns wound on the iron core is detected by controlling a counter and the photoelectric switch, including: During the process of the winding motor driving the iron core to rotate, the number of pulse signals output by the photoelectric switch is determined by controlling the counter. Determine the number of coil turns wound on the iron core based on the number of signals.

[0078] In this embodiment, the photoelectric switch outputs a pulse signal once for each revolution of the winding motor, wherein the pulse signal is a signal used by the counter for counting.

[0079] For example, a pulse signal is a discrete electrical signal that changes abruptly in a short period of time and then recovers rapidly. It has good periodicity and can be accurately counted by a counter by receiving it.

[0080] During the process of the winding motor driving the iron core to rotate, the control counter receives the pulse signal sent by the photoelectric switch, and determines the number of pulse signals output by the photoelectric switch through the counter. The number of signals is the number of pulse signals.

[0081] For example, during the process of the winding motor driving the iron core to rotate, a control counter counts the pulse signals to obtain the signal quantity.

[0082] Determine the number of coil turns wound on the iron core based on the number of signals.

[0083] For example, since the winding motor drives the iron core to rotate, it can be determined that the number of signals is equal to the number of coil turns on the iron core. Therefore, the number of coil turns wound on the iron core can be determined based on the number of signals.

[0084] In some embodiments of this application, a control method for a winding machine is provided. The winding machine further includes a frequency converter, which controls the winding motor to drive the iron core to rotate at a second speed, including: When the real-time coil turns are greater than or equal to the second winding turns, the control counter generates a speed change signal; Based on the speed change signal, the frequency converter is controlled to adjust the speed of the winding motor so that the winding motor drives the iron core to rotate at the second speed.

[0085] In this embodiment, the winding machine further includes a frequency converter, which is connected to the winding motor and is used to control the speed of the winding motor. For example, a frequency converter is a power control device that controls the speed of an AC motor by changing the frequency of the motor's operating power supply. It is widely used in industrial automation, energy-saving renovation, and intelligent control. Through a "rectification-filtering-inverting" circuit structure, the frequency converter converts fixed-frequency industrial frequency electricity (such as 50Hz) into AC electricity with adjustable frequency and voltage, thereby achieving precise control of the motor speed and transforming the motor from a "fixed speed, high energy consumption" to an intelligent operating mode of "on-demand speed adjustment, low energy consumption".

[0086] For example, the frequency converter is equipped with a high-speed operation section, a deceleration operation section, and a stop section to achieve smooth operation of the winding motor from high speed to low speed.

[0087] When the real-time coil turns are greater than or equal to the second winding turns, the control counter generates a speed change signal, which is a signal to notify the frequency converter to change the motor speed.

[0088] For example, the speed change signal can specifically be a control signal for motor speed change.

[0089] For example, the speed change signal can be specifically a voltage signal, and the speed value to be changed can be determined based on the voltage value of the voltage signal.

[0090] Based on the speed change signal, the frequency converter is controlled to adjust the speed of the winding motor so that the winding motor drives the iron core to rotate at the second speed.

[0091] For example, the frequency converter can analyze the speed change signal to determine the second speed, and then control the winding motor to drive the iron core to rotate according to the second speed.

[0092] In some embodiments, this application provides a control method for a winding machine, which controls a winding motor to drive an iron core to rotate at a first speed to wind a coil around the iron core, including: Determine the winding tension value corresponding to the iron core; Determine the first speed of the winding motor based on the winding tension value; The winding motor is controlled to drive the iron core to rotate at a first speed so that the winding motor can wind the iron core into a coil.

[0093] In this embodiment, the winding tension value corresponding to the iron core is determined, wherein the winding tension value is a preset tension value of the coil winding on the iron core.

[0094] For example, the winding motor drives the coil to wind by rotating the iron core. During the movement and winding process, the coil material is stretched by the iron core, which in turn causes tension to be generated inside the coil material.

[0095] For example, the rotational speed of the winding motor is directly proportional to the winding tension of the coil. The faster the rotational speed of the winding motor, the greater the winding tension, and the slower the rotational speed of the winding motor, the smaller the winding tension.

[0096] For example, the winding tension value can be manually set by the winding machine operator.

[0097] For example, the winding tension value can be determined based on the size of the iron core.

[0098] The first speed of the winding motor is determined based on the winding tension value.

[0099] For example, the winding tension value is proportional to the first rotational speed; the larger the winding tension value, the larger the first rotational speed, and the smaller the winding tension value, the smaller the first rotational speed.

[0100] The winding motor is controlled to drive the iron core to rotate at a first speed so that the winding motor can wind the iron core into a coil.

[0101] In some embodiments, this application provides a control method for a winding machine to determine the winding tension value corresponding to the iron core, including: Obtain the coil material corresponding to the iron core, and obtain the dimensional parameters of the iron core; Determine the coil size corresponding to the iron core based on the dimensional parameters; Determine the winding tension value based on the coil material and coil size.

[0102] In this embodiment, the coil material corresponding to the iron core is obtained, and the size parameters of the iron core are obtained, wherein the coil material is the specific material type of the coil.

[0103] For example, the choice of coil material directly affects its electrical performance, thermal stability, mechanical strength and cost, and needs to be comprehensively weighed according to the specific application scenario (such as frequency range, power level and working environment).

[0104] The coil material can be copper wire. High-purity oxygen-free copper (OFHC) is the most commonly used winding material. Copper wire has low resistance, which can effectively reduce copper loss and improve electromagnetic conversion efficiency.

[0105] The coil material can be silver-plated copper wire. In high-frequency applications, the skin effect is significant, and the silver plating layer can improve surface conductivity and reduce high-frequency loss, making it suitable for fields such as radio frequency coils and avionics.

[0106] The coil material can be a copper alloy. Adding trace amounts of elements such as silver and magnesium improves tensile strength while maintaining good conductivity, making it suitable for high-mechanical-stress applications such as high-speed motor rotor windings.

[0107] The coil material can be aluminum wire, which has a conductivity of about 61% that of copper, but has low density and low cost, and is often used in large transformers as an economical alternative.

[0108] The coil material can be silver wire, which has the best conductivity, but the cost is extremely high. It is only used in special high-frequency or high-reliability applications and is not suitable for mass production.

[0109] Based on the dimensional parameters, the coil size corresponding to the iron core can be determined, where the coil size refers to the size of the coil wound on the iron core.

[0110] For example, the coil size is proportional to the size parameter; the larger the size parameter, the larger the coil size, and the smaller the size parameter, the smaller the coil size.

[0111] Determine the winding tension value based on the coil material and coil size.

[0112] For example, a first tension value can be determined based on the coil material, and a second tension value can be determined based on the coil size. A weighted sum of the first and second tension values ​​yields the winding tension value.
