Motor magnetizer: what core indicators should be most concerned about when the factory selection

End-to-End Solution for Magnetization Automation

In the motor manufacturing process, the magnetizer is the key equipment that determines the magnetic performance and operational stability of permanent magnet motors, and the reasonableness of the selection has a direct impact on the production efficiency, product yield and long-term operating costs. As a national specialized, special and new “small giant” enterprise focusing on the development and production of magnetizing equipment, JiuJu motor magnetizer has become the preferred equipment for many factories due to its many years of technical accumulation. For factories, there is no need to pursue the complexity of professional parameters when selecting, focusing on the following core indicators, you can accurately match the production needs and avoid selection errors.

Magnetic field parameters and suitability are the core prerequisites for selection. The magnetic field strength of the magnetizer needs to match the material and specifications of the magnets produced in the factory. There are significant differences in the magnetic field strength required by different magnetic materials, and the magnetic field requirements of high coercivity materials differ from those of ordinary magnetic materials. At the same time, the uniformity of the magnetic field directly determines the consistency of the magnetic performance of the motor, if the uniformity is not good, it will lead to fluctuations in the motor speed, noise increase, quality equipment needs to effectively control the magnetic field strength error, through the optimization of the design of the coils of the JiuJi magnetizers, can achieve the whole area of uniform magnetization, to avoid the problem of local weak magnetism, to ensure that the effect of the magnetization is stable. In addition, the magnetizing energy needs to meet the demand of material saturation magnetization, capacitance capacity and magnetizing voltage will directly affect the size of the magnetizing energy, and need to be matched reasonably when selecting the type.

undefined

Operational stability and durability are critical to the continuity of a plant's production. The durability and protection of the core components of the magnetizer are of paramount importance. High-quality equipment will use high-quality core components with perfect over-voltage and over-current protection to reduce equipment failures and maintenance downtime. At the same time, the repeatability of the equipment also needs to be focused on, only to ensure stable repeatability to ensure the consistency of the magnetizing effect in mass production, which is also one of the core advantages of the JiuJu magnetizer, which can effectively protect the quality and stability of large-scale production in factories.

undefined

Production efficiency and compatibility need to be adapted to the factory's production capacity and flexible production needs. Different factories have different production rhythms, and the work cycle of the magnetizer needs to match the rhythm of the production line. JUJI magnetizers can provide suitable models according to the needs of the production line, seamlessly connecting with the automated production line to improve production efficiency. In addition, factories are often involved in the production of multiple types of motors, the equipment needs to have good compatibility, can quickly complete the switching of different magnet steel tooling, without the need for a single specification to purchase a separate device, thus reducing the upfront investment costs.

undefined

When factories select JiuJu motor magnetizers, the core is around the magnetic field adaptability, operational stability, production efficiency of the three core indicators, combined with their own magnetic material specifications, production capacity needs and production line type of comprehensive consideration. No need to blindly pursue high-end configuration, accurate matching of production scenarios, in order to achieve the goal of reducing costs and increasing efficiency, improve product competitiveness, so that the magnetizing equipment to become a real motor production assistance.
