Reduce Eddy Current Losses
In an alternating magnetic field, an induced electromotive force will be generated inside the bulk magnetic steel, which then forms eddy currents, resulting in energy losses and heat generation. However, laminated magnetic steel is composed of thin magnetic steel sheets stacked one on top of another. Since the sheets are insulated from each other, they can effectively block the paths of eddy currents, thereby significantly reducing eddy current losses, improving the utilization efficiency and working stability of the magnetic steel. This advantage is particularly evident in high-frequency application scenarios.
Enhance Magnetic Field Strength and Uniformity
Laminated magnetic steel can achieve precise control and adjustment of the magnetic field by optimizing the shape, size, and arrangement of the laminations, making the magnetic field distribution more uniform and increasing the magnetic field strength. In equipment such as motors, a uniform magnetic field helps to improve the operating efficiency of the motor, reduce torque ripple and noise, and enhance the overall performance of the equipment.
It can be customized according to specific application requirements. By adjusting parameters such as the number of layers, thickness, and spacing of the laminations, flexible control over the magnetic field strength and distribution can be realized, better meeting the special requirements of different equipment for the magnetic field.
Improve Thermal Stability
The laminated structure increases the heat dissipation surface area of the magnetic steel, which is beneficial for heat dissipation. This reduces the temperature rise of the magnetic steel during the working process, improves its thermal stability, reduces magnetic attenuation and performance degradation caused by temperature changes, and extends the service life of the magnetic steel.
Since the eddy current losses of laminated magnetic steel are relatively small, less heat is generated under the same working conditions, further reducing the risk of demagnetization and other problems caused by overheating. This enables it to maintain good performance in high-temperature environments or under high-load working conditions.
Increase Design Flexibility
Laminated magnetic steel can be flexibly designed and customized according to specific application requirements. It can be fabricated into magnetic steel components of various shapes, sizes, and complex structures to meet the special requirements of different equipment, such as various special-shaped magnetic steel structures in fields like motors, transformers, and sensors.
It has better integration with other materials or components and can be conveniently combined and assembled with other metal or non-metal materials to achieve the integration of multiple functions and improve the overall performance and reliability of the equipment.
Reduce Magnetic Field Leakage
The structure of laminated magnetic steel is relatively compact, which can reduce the leakage of magnetic flux, improve the magnetic energy utilization rate of the magnetic steel, make the magnetic field act more concentratedly on the target area, enhance the effective working range and magnetic field strength of the magnetic steel, and thus improve the working efficiency and performance of the equipment.
In some applications with strict requirements for magnetic field leakage, such as high-precision measuring instruments and magnetic resonance imaging equipment, laminated magnetic steel can effectively reduce the interference of the magnetic field on the surrounding environment and other equipment, improving the stability and safety of the equipment.
