Which magnetizing machine works best with the magnets in an axial flux motor?
End-to-End Solution for Magnetization Automation
Automated Magnetic Charging Integrated Solution
Axial-flux motors typically use thin magnets arranged in a dense, alternating N/S polarity pattern, with the magnetic circuit running axially. The quality of the magnetization directly determines the motor’s torque density, smoothness of operation, and overall efficiency. Therefore, magnetization equipment cannot simply adopt the traditional radial motor design; instead, a specialized solution must be developed that accounts for the structural characteristics of the magnets.
When selecting a model, attention must be paid to three key indicators. First, the compatibility between the magnetization direction and the number of poles; For axial magnets, the operating magnetic field must be output along the motor’s axial direction. Specialized axial multi-pole magnetizing fixtures are required to precisely match the number of pole pairs and their arrangement angles, ensuring consistent magnetic field direction and uniform distribution across each pole. This prevents torque fluctuations and increased operating noise caused by magnetic field deviations between poles. Second is the precision of magnetization energy control. Thin magnets have low impact resistance; excessive magnetization energy can cause them to shatter or degrade in performance, while insufficient energy prevents them from reaching saturation. The equipment must be capable of stepwise capacitive energy control to accommodate the magnetization parameters of magnets of different grades and thicknesses. Third, closed-loop process control capability: It is recommended that the magnetization station integrate polarity identification and surface magnetic field detection functions to instantly identify workpieces with incorrect polarity or weak magnetism, thereby preventing defective products from entering subsequent assembly processes.
Common selection pitfalls in the industry that should be avoided: Directly modifying a radial magnetizer for use can result in insufficient magnetization saturation due to a mismatch in the magnetic field direction; using generic fixtures to accommodate multiple sizes of magnets can lead to issues such as poor magnetic field uniformity and significant pole position deviations, making it difficult to ensure long-term mass production stability.
To meet the magnetization process requirements for axial flux motors, Jiuju offers matching magnetization equipment and specialized fixture solutions that support axial multipole magnetization for a wide range of magnet specifications. Equipped with precise energy control and online detection modules, these solutions ensure consistent magnetization saturation and polarity, meeting the process requirements for large-scale mass production. During the product selection phase, it is recommended to conduct magnetization validation based on the magnet grade, number of poles, and mass production cycle time, using uniform saturation and high efficiency with low losses as the core evaluation criteria.

Magnetization itself is a physical process that takes place in milliseconds; what truly slows down the overall production cycle are the manual loading, unloading, and alignment and calibration steps. In manual magnetization mode, workers must pick up and place each part individually and verify the polarity direction, which takes several seconds per part. Production capacity fluctuates significantly depending on the workers’ skill level and fatigue, and the strong magnetic field environment also poses safety hazards.

Magnetic screwdrivers are typically made of alloy steel, which inherently possesses some residual magnetism. When magnetized, the screwdriver is placed in a strong pulsed magnetic field, causing the internal magnetic domains to align axially. Once the external magnetic field is removed, the screwdriver retains a stable magnetic field, enabling it to attract iron screws.

”In traditional pre-magnetization processes, magnetizing the magnets in advance causes the magnetic poles to repel each other and attract iron filings during motor assembly, which limits yield rates and poses safety hazards.” The "assemble first, magnetize later" approach uses integrated magnetization technology to allow magnets to be precisely positioned in a non-magnetized state, with magnetization and shaping performed uniformly after assembly is complete. This innovation eliminates magnetic interference, enables the design of motors with higher rotational speeds, and boosts assembly efficiency by more than 30%. It is rapidly becoming the mainstream choice among manufacturers of new energy motors and servo motors.
