How to Choose the Right Power Rating for a Magnetizing Machine Without Making Mistakes? A Comprehensive Guide to Matching Methods

Automated Magnetic Charging Integrated Solution
When selecting the power rating for a magnetizing machine, “bigger is not necessarily better.” If the power rating is not properly matched to the characteristics of the magnets and the production process, it can result in wasted energy and costs at best; at worst, it can lead to incomplete magnetization and damage to the magnets, directly affecting the stability of the final motor products. Proper selection requires comprehensive evaluation based on three key factors: magnet parameters, magnetization scenarios, and mass production cycle times.
First, we use the characteristics of the magnet as the core benchmark. The essence of magnetization is to bring the magnet to saturation magnetization through an instantaneous strong magnetic field; the energy required is determined by the magnet’s material grade, volume, and coercive force. Materials with high coercive force, such as neodymium-iron-boron, and large-sized magnets require higher magnetization energy; thin and small-sized magnets, on the other hand, demand greater precision in energy control, as power overload can easily cause the magnets to fracture or degrade in performance. When selecting a model, first calculate the minimum energy required for saturation magnetization, then select a main unit with the corresponding power rating.
Second, consider the relationship between the magnetization method and fixture efficiency. For the same main unit power, there are significant differences in magnetic field utilization between different methods—such as axial multipole magnetization and radial magnetization—and the magnetic field focusing capability of specialized fixtures directly determines the effective magnetization intensity. If the fixture is poorly designed, even a high-power main unit will struggle to achieve saturation magnetization. Therefore, power selection must be evaluated in tandem with the fixture design; the equipment’s capabilities cannot be judged solely based on its rated power.
Finally, match the production cycle and operating conditions. In continuous mass production scenarios, where magnetization occurs frequently, the equipment must have sufficient power headroom and heat dissipation capacity to prevent fluctuations in magnetization accuracy caused by heat generated during high-frequency operation. In small-batch, multi-product scenarios, priority should be given to a wide adjustable power range to accommodate the magnetization requirements of various magnet specifications.
Common selection pitfalls to avoid: Blindly pursuing high power leads to excessive equipment costs and energy consumption; focusing solely on the host’s rated power while ignoring actual output energy and compatibility with fixtures; failing to allow for future specification updates, resulting in equipment incompatibility after product upgrades. To address magnetization power matching requirements, Jiuju can provide selection calculations based on magnet parameters and production conditions. By combining specialized magnetization fixtures with energy control modules, we ensure reasonable power matching while guaranteeing saturation magnetization, thereby reducing the risk of mis-selection.

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.
