Ultra-thin silicon steel (especially 0.1-0.2mm thick) is a core material for drive motors in new energy vehicles, and its technical level directly affects the efficiency, power density, and overall vehicle performance of the motor. 1. Improved energy efficiency: Generally speaking, the thinner the silicon steel sheet, the lower the eddy current loss. For example, reducing the thickness of the silicon steel sheet from 0.5mm to 0.1mm can reduce eddy current loss to 1/25 of the original. Therefore, new energy vehicle motors made of ultra-thin silicon steel can reduce energy waste and extend the driving range.   2. Power density: Thinner silicon steel allows motors to operate at higher speeds, thus increasing power density. For example, motors using 0.1mm ultra-thin silicon steel can reach speeds of up to 31,000 rpm. Motors made with ultra-thin silicon steel output more power in the same volume, or reduce motor size for the same power, contributing to vehicle weight reduction.   3.  Reduce iron loss: Iron loss is a key indicator for measuring the energy loss of silicon steel sheets. Ultra-thin silicon steel has a lower iron loss value, which can directly reduce the heat generation and energy waste during motor operation, and help improve output power and range.   Ultra-thin silicon steel is a crucial component in the performance race of new energy vehicles. As material thickness continues to decrease to 0.1mm and below, the motors in new energy vehicles will become more powerful, efficient, and compact. The development of ultra-thin silicon steel continues, with a clear trend towards thinner, higher-performance (lower iron loss, higher strength) and broader applications (expanding from new energy vehicles to low-altitude aircraft, humanoid robots, etc.).   Shungesteel now offers ultra-thin silicon steel with a thickness of 0.1-0.2 mm, suitable for use in electric motors for new energy vehicles, providing high-quality material solutions for manufacturers of high-performance electric motors for new energy vehicles.Welcome to learn more.  

Ultra-thin silicon steel (0.1-0.2mm) is a key material driving robotics technology toward high performance and precision, and is indispensable, especially in advanced robotic systems that require high power density, fast response and precise positioning.   Ultra-thin silicon steel is mainly used in the following core components of robots, making it an ideal material for their "power heart".   Joint motors: The movements of multiple joints in a humanoid robot, such as the neck, waist, and fingers, rely on joint motors for power and precise control. A single humanoid robot can contain up to 50 motors. Motors made of ultra-thin silicon steel can output powerful torque in a very small volume and achieve millisecond-level response speeds, making the robot's movements more flexible and human-like.     Dexterous Hands and Coreless Motors: Dexterous hands in robots require more precise motors, such as coreless motors and frameless torque motors. Ultra-thin silicon steel can meet the manufacturing requirements of coreless motors for dexterous hands, which are only 6 millimeters in size, and is the foundation for achieving fine finger manipulation.   The superior performance of ultra-thin silicon steel stems from the fundamental advantages of its physical properties:   Minimizing Iron Loss: Silicon steel sheets experience energy loss (iron loss) due to eddy currents in alternating magnetic fields, which is dissipated as heat. Eddy current loss is proportional to the square of the steel sheet thickness. Reducing the thickness of silicon steel sheets from the traditional 0.35mm or 0.5mm to 0.1mm or 0.2mm, creating ultra-thin silicon steel, significantly reduces iron loss.     Achieving High Power Density and Miniaturization: Using ultra-thin silicon steel allows for the manufacture of smaller and lighter motors with the same power output. This is crucial for robot joints where space is extremely limited, directly contributing to their miniaturization and weight reduction.   Shunge Steel now offers ultra-thin silicon steel with a thickness of 0.1-0.2 mm, providing material solutions for high-performance robot manufacturers. Welcome to learn more.  

Ultra-thin silicon steel and self-adhesive coating technology are core technologies in the manufacturing of high-end motors and transformers. Their combined application is driving the development of products in fields such as new energy vehicles and power electronics towards higher efficiency, higher power density, and lower noise. When ultra-thin silicon steel is combined with self-adhesive coating technology, a synergistic effect of "1+1>2" can be achieved, with the main advantages being: 1. Significantly Reduced Losses in Ultra-Thin Silicon Steel Cores: Self-adhesive coating technology avoids the mechanical stress and localized short circuits associated with traditional welding and riveting through overall bonding, thus better preserving the excellent magnetic properties of ultra-thin silicon steel. Tests show that compared to welded cores, self-adhesive cores can reduce iron losses by approximately 5% and excitation current by 9%. 2. Effectively reduces vibration and noise: The self-adhesive coating technology effectively suppresses vibration transmission between silicon steel sheets, resulting in better overall core integrity. Data shows that the noise generated by a self-adhesive core can be approximately 5 dB lower than that of a welded core.   3. Facilitating Miniaturization and Weight Reduction: Self-adhesive technology eliminates or reduces the use of traditional fasteners (such as end plates and pressure rings), maximizing the effective length of the core within a limited space, thus achieving a smaller volume for the same power output. These advantages make this technology combination ideal for applications with stringent requirements for efficiency, size, and noise, such as drive motors for new energy vehicles, high-end home appliance compressors, drone power systems, ultra-high voltage transformers, and precision power electronic equipment. Shunge Steel now offers ultra-thin silicon steel with a thickness of 0.1-0.2mm, as well as axial cores made from ultra-thin silicon steel using self-adhesive coating technology.

Axial cores are a special type of core used in motors or transformers, the raw material is usually silicon steel, characterized by magnetic flux (magnetic field) primarily distributed along the rotational axis or axial direction of the device. This contrasts sharply with common radial cores (where magnetic flux is distributed radially).   Compared to traditional silicon steel, the application of ultra-thin silicon steel in axial cores does indeed bring a series of significant advantages, mainly due to the improvement in its physical and electromagnetic properties. The application of ultra-thin silicon steel in axial cores is one of the key technologies for achieving high-frequency, high-efficiency, and miniaturized motors and transformers. Advantages: 1. In terms of electromagnetic performance, ultra-thin silicon steel is applied to the axial core. Due to the extremely thin thickness of ultra-thin silicon steel, the eddy current flow path is restricted, and the loop resistance is increased. Moreover, ultra-thin silicon steel itself has a low iron loss value, which can significantly reduce iron loss (especially eddy current loss) compared with traditional silicon steel, and improve the efficiency of motors/transformers. 2. In terms of structural design, axial cores made of ultra-thin silicon steel generally use self-bonding technology. Self-bonding technology uses special adhesives to solidify the silicon steel sheets as a whole, avoiding the damage to the material caused by traditional riveting/welding. 3. In terms of thermal management, the axial core made of ultra-thin silicon steel uses self-adhesive technology, and the self-adhesive coating fills the gaps between the sheets, forming an efficient axial heat conduction path; while the low iron loss characteristics of ultra-thin silicon steel can reduce heat generation from the source. In summary, ultra-thin silicon steel, applied to axial cores through special material processing and structural design, offers significant advantages in reducing high-frequency losses, increasing power density, optimizing heat dissipation, and improving NVH performance. This makes it highly suitable for the stringent requirements of high-efficiency, compact size, and high performance in current high-end motors and transformers.

Silicon steel is extremely important, it is not only a cornerstone material for the modern power and electronics industries, but is also hailed as an "artwork" and a "jewel in the crown" among steel products.With technological advancements and the demands of industrial development, silicon steel has gradually moved towards ultra-thin designs. Ultra-thin silicon steel with a thickness between 0.1 mm and 0.2 mm is an indispensable core material for many cutting-edge high-end equipment. Its value mainly stems from a key physical property: the eddy current loss of silicon steel sheets is proportional to the square of their thickness. This means that when the thickness is reduced from the conventional 0.35 mm or 0.5 mm to 0.1 mm, the eddy current loss can be significantly reduced to 1/25 or even lower, thereby greatly improves the energy conversion efficiency and high-frequency performance of motors made from CRNGO materials.Application fields: 1. New energy vehicle drive motors: The high efficiency of ultra-thin silicon steel enables new energy vehicle motors to extend their driving range, and its high power density can further reduce the size of the motor. Extremely low iron losses also result in higher energy efficiency, supporting ultra-high motor speeds (such as 31,000 rpm), thereby increasing power density. 2. Humanoid robot joint motors: Humanoid robot joint motors require miniaturization, lightweight, high precision, and fast response. The ultrathin thickness of ultra-thin silicon steel meets the stringent requirements of micro joint motors such as hollow cups and frameless torque motors in tiny spaces; moreover, its high magnetic induction ensures strong and precise power output. 3. Drones/eVTOL: This type of motor needs to operate at extremely high speeds (medium-high frequencies, such as 400-1000Hz) and requires extremely light weight. The excellent iron loss characteristics of ultra-thin silicon steel at medium-high frequencies ensure that the motor maintains low loss and high efficiency at high speeds, directly improving the aircraft's endurance and maneuverability; The level of research and development and industrialization of ultra-thin silicon steel is becoming an important indicator of a country's competitiveness in high-end manufacturing and emerging industries.

Its core advantage lies in achieving a "double" increase in motor energy efficiency, power density, and overall performance through "thinning" of the physical thickness. • Improve energy efficiency and reduce iron losses. In motors, silicon steel sheets generate eddy currents due to electromagnetic induction, causing energy to be lost as heat; this loss is called iron loss. Ultra-thin silicon steel sheets can effectively limit the generation path of eddy currents, thereby significantly reducing iron losses. •Achieving Miniaturization and Lightweighting Ultra-thin silicon steel directly leads to the miniaturization and light weighting of both the material itself and the final application products. Higher Power Output in the Same Volume: For applications highly sensitive to space and weight, such as drones, humanoid robots, and low-altitude aircraft, using 0.1 mm or 0.2 mm ultra-thin silicon steel allows motors to output higher power in the same volume, or to make the motor smaller and lighter while maintaining power. This is crucial for improving equipment mobility and endurance, meeting the demands of high-end applications. •Core Advantages of Ultra-thin Silicon Steel in Different Application Scenarios New Energy Vehicle Drive Motors: Its core advantage lies in low iron loss, improving motor efficiency, extending vehicle range, and making energy utilization more efficient.

The pursuit of "ultra-thin" silicon steel is driven by the core objective of achieving higher energy efficiency, meeting the demands of high-frequency applications, and promoting the miniaturization and lightweighting of equipment.   The fundamental advantage of the "ultra-thin silicon steel" design lies in the principles of physics. In an alternating magnetic field, eddy currents are generated inside the silicon steel sheet, causing energy to be lost as heat (eddy current loss). Thinner silicon steel sheets confine eddy currents to a narrower vertical cross-section, effectively increasing the resistance of the eddy current path and thus suppressing eddy current loss. Therefore, the higher the operating frequency, the thinner the silicon steel sheet needs to be.     However, the pursuit of "ultra-thin silicon steel" also comes with enormous technological challenges. Reducing thickness means an exponential increase in the demands of process control, especially in rolling and annealing, where even the slightest deviation can lead to strip breakage. Simultaneously, as the silicon content increases (aimed at improving resistivity and optimizing magnetic properties), the material's brittleness increases significantly, making the rolling and processing of ultra-thin products extremely difficult.     The development of "ultra-thin silicon steel" is driven by clear high-end application demands. For example, the new energy vehicle industry pursues high-speed electric drive systems (such as BYD's 30,000 RPM motor). High speed means high frequency, requiring the use of silicon steel sheets as thin as 0.20mm or even thinner to control iron losses, while simultaneously achieving motor miniaturization and weight reduction. In fields such as high-end medical equipment and eVTOL low-altitude aircraft, the extreme requirements for motor size, weight, and response speed are also driving the development of ultra-thin silicon steel technology at 0.15mm, 0.10mm, and even 0.04mm.     Shunge Steel's ultra-thin non-oriented silicon steel, with its superior magnetic properties, has become an ideal material choice for many high-end manufacturing fields. It features low iron loss, high magnetic permeability, and stable magnetic properties, significantly improving energy conversion efficiency. Shunge Steel closely monitors the technological frontiers and development trends of ultra-thin silicon steel, and is committed to providing customers with advanced material solutions.
