Aluminum Wire Vertical Winding Coil

In the development process of modern electrical and electronic equipment, coils, as key basic components, their performance directly affects the overall efficiency of the equipment. As an innovative coil structure, the offset film wrapped wire coil is gradually emerging in many fields due to its unique design and performance advantages. Pugu Electromechanical Technology (Suzhou) Co., Ltd. has been actively exploring in the research and development, production and other aspects of related products, contributing to the application and promotion of offset film wrapped wire coils. Below, we will delve into the various advantages of offset film wrapped wire coils.

First, enhance space utilization and achieve a compact layout

During the winding process of traditional coils, the arrangement of each turn is relatively regular, and there is often a certain amount of gap waste between the turns and in the overall spatial layout of the coil. The offset film wrapped wire coil changes the arrangement of the turns through a unique offset winding process. The adjacent turns of the thread are no longer neatly arranged in parallel but interweave with each other, fitting closely like a jigsaw puzzle. This ingenious design has greatly enhanced the space utilization rate. Taking the rotor coil coil in the motor as an example, the offset film wrapped wire coil with a layered offset three-phase disc motor coil packaging structure can arrange the coil structure with high space utilization, thereby obtaining a small-volume rotor coil coil after packaging. Compared with traditional motor coils, under the same power demand, using offset film wrapped wire coils can make the motor more compact and lightweight. For some application scenarios with strict requirements for the volume of equipment, such as the drive motors of electric vehicles and the micro motors of portable electronic devices, the advantage of the offset film wrapped wire coil becomes particularly important. It not only helps to achieve the miniaturization and lightweight design of the equipment, but also enables the arrangement of more functional components within a limited space, enhancing the integration and overall performance of the equipment. In the research and development of related products, Pugu Electromechanical pays close attention to the optimization of space utilization. By constantly improving the winding process and mold design, the offset film wrapped wire coils it produces perform outstandingly in terms of space utilization.

Second, enhance electromagnetic performance and improve energy conversion efficiency

(1) Optimize the magnetic field distribution

From the perspective of electromagnetic principles, the distribution of the magnetic field generated by a coil is closely related to the winding method of the coil. Due to its staggered winding method, the magnetic field distribution generated when the current passes through the coil is more uniform. When current flows through a coil, each turn of the coil generates its own magnetic field. In traditional neatly arranged coils, local areas of magnetic field enhancement or weakening may occur due to interaction among these magnetic fields, resulting in an uneven distribution of the magnetic field. In the offset film wrapped wire coil, the magnetic fields generated by each turn of the coil interweave and complement each other, effectively reducing the distortion and non-uniformity of the magnetic field. In wireless power transmission (IPT) systems, the adoption of offset compensation arc coils (an application form of offset membrane-wrapped coils) can better adapt to the spatial position changes between different devices and reduce energy loss caused by offset. By rationally arranging the shape and position of the coils, automatic compensation during offset can be achieved, enabling the system to maintain a relatively stable and uniform magnetic field distribution in various complex usage environments, thereby enhancing the stability and efficiency of energy transmission.

(2) Reduce resistance and reactance

When current passes through a coil, it is hindered by resistance and reactance, resulting in energy loss. During the winding process of the offset film wrapped wire coil, by precisely controlling parameters such as the spacing and Angle of the offset, the DC resistance and AC reactance of the coil can be effectively reduced. On the one hand, the offset winding makes the connection between the turns of the wire tighter, reducing the contact resistance during the current transmission process. On the other hand, a reasonable offset layout optimizes the inductive characteristics of the coil and reduces the hindrance of alternating current reactance to the current. This means that under the same current input conditions, using offset film wrapped wire coils can reduce energy loss in resistance and reactance, and more electrical energy can be converted into useful electromagnetic energy output. Take transformers as an example. Using offset film wrapped coils as windings can enhance the energy conversion efficiency of transformers, reduce heat loss, extend the service life of transformers, and to a certain extent, improve the overall operational efficiency of the power system. During the production process, Pugu Electromechanical strictly screens raw materials and precisely controls the winding process parameters to ensure that the produced offset film wrapped wire coils have excellent electromagnetic performance, effectively reducing energy loss caused by resistance and reactance.

Third, enhance production efficiency and reduce manufacturing costs

(1) Simplify the winding process

The traditional multi-layer coil winding process is often rather complex, requiring frequent operations such as interlayer conversion and turn positioning during the winding process. This not only takes a lot of time but also is prone to winding errors. The winding process of the offset film wrapped wire coil is relatively simplified. Take the electromagnetic coil with offset winding grooves as an example. The electromagnetic coil can be wound layer by layer through the offset winding grooves. After completing the single-turn multi-layer winding at one time, the next turn can be wound layer by layer. This winding method reduces the need for multiple adjustments to the winding position and direction in the traditional winding process, significantly enhancing the winding efficiency. When mass-producing coils, the improvement in production efficiency means that more products can be produced within a unit of time, thereby reducing the production cost of individual products. Meanwhile, due to the simplification of the winding process, the difficulty of manual operation and the probability of errors have also decreased accordingly, and the quality stability of the product has been improved.

(2) Reduce waste of raw materials

In traditional coil winding, to ensure the insulation performance and structural stability of the coil, a large amount of insulating materials are often used and a certain margin is reserved during the winding process to deal with possible winding errors, which inevitably leads to the waste of raw materials. The offset membrane-coated wire coil uses a special membrane-coated wire as the conductor. This membrane-coated wire itself has good insulation performance, reducing the use of additional insulation materials. Moreover, due to the precision and efficiency of its winding method, the usage of wires can be more precisely controlled during the winding process, reducing the waste of wires caused by winding errors. When manufacturing motor coils, the design of using offset film wrapped wire coils can reduce the usage of raw materials such as enameled wire while meeting the performance requirements of the motor, lowering the cost of raw material procurement. At the same time, it is more in line with the concept of environmental protection and reduces the generation of waste during the production process. In its production practice, Pugu Electromechanical has further explored the potential of the offset film wrapped wire coil in improving production efficiency and reducing costs by optimizing the production process and process parameters, providing customers with high cost-performance products.

Fourth, enhance stability and reliability and extend service life

(1) Reduce the risk of short circuits

During the operation of electrical equipment, inter-turn short circuits and inter-layer short circuits in coils are among the common causes of faults, which can seriously affect the normal operation of the equipment and even lead to safety accidents. The offset film wrapped wire coil has a natural advantage in design and manufacture to reduce this short-circuit risk. On the one hand, for electromagnetic reels with isolation ribs and offset winding ribs, adjacent coils are separated by isolation ribs, which serve as insulation between coil turns and prevent short circuits between coil turns. Meanwhile, by using the offset winding grooves for staggered layer winding, the potential difference between layers is reduced to a minimum, thereby minimizing the possibility of interlayer short circuits. On the other hand, the insulating film of the film-wrapped wire is tightly wrapped around the surface of the conductor, providing a reliable insulating protection layer and further enhancing the insulation performance of the coil. Applying offset film to wrap the coil in the coil coil of the induction cooker can effectively prevent dangerous situations such as burning out and explosion caused by short circuits between coil turns or between coil layers, improve the reliability and safety performance of the electromagnetic heating equipment, extend the service life of the equipment, and reduce the cost of equipment maintenance and replacement.

(2) Adapt to complex working conditions

In practical applications, many electrical devices are exposed to complex and changeable working environments, such as high temperatures, high humidity, and strong electromagnetic interference. The offset film wrapped wire coil, with its excellent structural design and material selection, can better adapt to these complex working conditions. For instance, in high-temperature environments, the insulating materials used in membrane-coated wires typically have high heat resistance, ensuring good insulation performance even in high-temperature conditions and preventing electrical faults caused by a decline in insulation performance. In a strong electromagnetic interference environment, the offset film-wrapped wire coil reduces the impact of external electromagnetic interference on the normal operation of the coil through an optimized magnetic field distribution and excellent shielding performance (some specially designed offset film-wrapped wire coils will add a shielding layer), ensuring the stable operation of the equipment. In the motors, sensors and other equipment on industrial automation production lines, the use of offset film wrapped wire coils can enhance the stability and reliability of the equipment in complex industrial environments, ensuring the continuity and efficiency of production. The offset film wrapped wire coils produced by Pugu Electromechanical strictly control the quality inspection process to ensure that the products can operate stably under various complex working conditions, providing reliable product guarantees for customers.

This system enhances the convenience and stability of wireless charging for electric vehicles by real-time monitoring and adjusting the positions of the transmitting and receiving coils to maintain a good energy transmission state, promoting the development and popularization of wireless charging technology for electric vehicles. In new energy power generation equipment such as wind power generation and solar power generation, offset film wrapped wire coils can be applied to key components like transformers and inverters, enhancing the energy conversion efficiency and stability of these components, thereby improving the performance of the entire new energy power generation system.

(2) Applications in the fields of smart home and consumer electronics

In the fields of smart home and consumer electronics, the miniaturization and high performance of products are important trends in development. The offset film wrapped wire coil precisely conforms to this trend.
