Multi-layer stacked ferrite ring magnets are customized combined magnetic components formed by stacking and assembling multiple single-piece annular ferrite magnets according to specific magnetic circuit design and performance requirements. Based on ordinary annular ferrite magnets, through scientific multi-layer stacking technology, the product realizes superposition and optimization of magnetic field strength, magnetic flux and magnetic circuit distribution, solving the problem of insufficient magnetic force and limited magnetic coverage of single-piece ring magnets in high-demand scenarios. It is a high-efficiency customized magnetic product widely used in motor equipment, electromagnetic devices, sensing equipment and industrial magnetization fields.

In terms of production technology, multi-layer stacked ferrite ring magnets adopt high-precision sintered annular ferrite single pieces with consistent specifications and uniform magnetic performance as the base material. Through strict screening of single-piece magnetic parameters, precision trimming of flatness and parallelism, and professional stacking and bonding assembly process, the overall concentricity and flatness of the stacked magnet group are ensured. The internal stacking gap is controlled within the micron level, which avoids magnetic field leakage caused by assembly gaps and ensures the superposition effect of magnetic force layer by layer. According to customer performance requirements, it can be stacked in equal thickness, unequal thickness, equal magnetic pole and cross magnetic pole modes to form different magnetic field distributions such as uniform strong magnetic field, gradient magnetic field and regional concentrated magnetic field.

The core performance advantage of multi-layer stacked ferrite ring magnets is the adjustable and amplified magnetic performance. The multi-layer stacking structure can effectively increase the overall magnetic flux and surface magnetic strength on the premise of ensuring the stability of the ferrite magnet itself, realizing stronger magnetic adsorption force and magnetic field radiation range than single-piece products of the same volume. At the same time, the stacked structure has better structural stability and vibration resistance. The integrated assembly formed by special adhesive and fixing process can resist long-term mechanical vibration and high-frequency operation, no loose layer, no displacement, and maintain stable overall magnetic performance. In addition, the product retains the excellent high-temperature resistance and anti-demagnetization characteristics of ferrite magnets, and can work stably in high-temperature and high-frequency operating environments for a long time.

This type of stacked ring magnets is mainly used in professional industrial and electronic fields. It is widely applied in small and medium-sized permanent magnet motors, vibration motors, electromagnetic sensors, magnetic induction devices, industrial magnetizing equipment, magnetic separation equipment and precision electronic instruments. In motor manufacturing, multi-layer stacked ring magnets can optimize the motor magnetic circuit, improve motor power and operating efficiency, and reduce energy consumption; in sensing equipment, the superimposed uniform magnetic field can improve the induction accuracy and sensitivity of sensors; in magnetic separation and magnetization industries, the enhanced magnetic field can improve the working efficiency of equipment. Support customized outer diameter, inner diameter, thickness and stacking layers, flexible to meet the personalized performance and size requirements of different industrial equipment, and is a high-quality customized magnetic component for high-precision and high-efficiency industrial equipment.
