The technical parameters of a magnetizer directly determine its performance and scope of application. A correct understanding of these parameters is essential for equipment selection.

Analysis of the main technical parameters:

1. Magnetizing voltage: This is the key parameter that determines the strength of the magnetic field. Common magnetizing voltages range from 1000V to 6000V. Materials with high coercivity, such as NdFeB, usually require a magnetizing voltage of 3000V or more.

2. Capacitor capacity: The capacitor is the core energy storage element of the magnetizer, with a capacity ranging from 2000μF to 60,000μF. The larger the capacitance, the more energy is stored and the stronger the magnetizing energy.

3. Magnetizing energy: calculated as E = 0.5 × C × V² in Joules (J). The magnetizing energy directly affects the magnetizing effect, and generally needs to be 2-3 times the energy required for saturation magnetization of the material.

4. Repeatability: Voltage repeatability is usually required to reach ±1V, which ensures the consistency and stability of the magnetization effect.

5. Work cycle: refers to the interval between two magnetizations, generally from 1.6 to 6 seconds, which affects productivity.

The technical parameters of JiuJu magnetizer are at the leading level in the industry, and its voltage repeatability reaches ±1V, much higher than the industry standard. JiuJu magnetizer adopts imported oil-immersed energy storage capacitors, with 5-year replacement quality assurance, to ensure the long-term stable operation of the equipment.

Application Matching Suggestion: JiuJu magnetizers offer a complete range of products. For small-sized NdFeB magnets, the MA-1320 magnetizer (1280V, 2000μF) is recommended; for medium-sized products, the MA-2030 (1980V, 3000μF) is recommended; for large-sized and highly-demanding products, the MA-3060 (2980V, 6000μF) or above is required. The working cycle of JUJI magnetizers ranges from 1.6 seconds to 6 seconds, which can meet the requirements of different production efficiency.
