Core Considerations for Selecting Magnetization Equipment: Six Key Technical Indicators to Monitor

End-to-End Solution for Magnetization Automation

For motors, horns and other manufacturing scenarios that rely on magnets, the technical indicators of magnetizing equipment directly determine the final performance of magnets, and at the same time affect the production yield of products. Therefore, in the selection process, we need to focus on the following six core technical indicators, as described below:

undefined

Magnetization uniformity is the key to determining the balance of magnetic field distribution of the magnet. Once the uniformity is not up to standard, the magnetic circuit of the motor will form an "uneven strength area", which not only triggers unstable rotational speed and higher operating noise, but also may directly affect the service life of the motor. When judging the core to see whether the error of magnetic field strength in each area of the magnet is controlled within 3%, for example, JiuJi magnetizing equipment through optimizing the design of multi-pole coils, which can achieve the new energy automobile motor magnets uniformly magnetized throughout the entire region, effectively avoiding the problem of local weak magnetism.

2. Why does the range of magnetic field strength need to be precisely matched to production requirements?

The magnetizing strength required for different magnet sizes varies significantly: magnets for 3C motors require a magnetizing field of 8,000-12,000Gs, while magnets for new energy vehicle drive motors require 15,000-20,000Gs. If the strength range of the magnetizing equipment does not cover the actual requirements, the magnets will be insufficiently magnetized (magnetic properties will not be up to standard) or over magnetized (risk of demagnetization of the magnets will increase). When selecting a magnet, you should first define the specifications of the magnets for your own production and prioritize equipment with adjustable strengths that fully cover the target range.

Magnetizing efficiency is directly related to the capacity output of the entire production line. Traditional magnetizing equipment takes 5-8 seconds for a single magnetization, with an hourly production capacity of 400-500 pieces, making it difficult to keep up with the production rhythm of automated motor production lines. High-efficiency magnetizing equipment needs to have the characteristics of "short magnetizing cycle and high production capacity per unit time", like JiuJu magnetizing equipment through capacitor energy storage optimization technology, the single magnetizing time is compressed to 2-3 seconds, and the hourly production capacity has successfully exceeded 1,000 pieces, which is able to seamlessly connect with the assembly line tempo, and effectively avoid the capacity bottleneck of the production line.

Frequent failures of magnetizing equipment can lead to interruptions and downtime of the production line, bringing economic losses to the production. To determine the operational stability of the equipment, we need to focus on two core concerns: first, the durability of core components such as high-voltage capacitors and discharge switches, and second, whether the equipment is equipped with over-voltage, over-current and other safety protection features. Generally speaking, ISO9001 certified magnetizing equipment can achieve 8 hours of continuous trouble-free operation, which can significantly reduce maintenance downtime. For example, JiuJu magnetizing equipment has undergone rigorous testing and validation, which can provide a reliable guarantee for production continuity.

In the manufacturing process of electric motors, magnets of different shapes and sizes, such as ring and tile, are often used. If the magnetizing equipment is not compatible enough, it is necessary to change the jigs and fixtures frequently, which will significantly reduce the production efficiency. High-quality magnetizing equipment should have the ability to change molds quickly. For example, JUJI magnetizing equipment can complete the switching of different magnet sizes within 3 minutes, which can fully meet the flexible production needs of multi-model motors without the need to purchase additional special equipment for a single magnet size.

In an intelligent production line, the magnetizing equipment must have the ability to interface with the MES system in order to realize automatic retrieval of magnetizing parameters and full traceability of production data. If the equipment lacks intelligent configuration, it is necessary to manually set the parameters, which is not only prone to operational errors, but also difficult to trace the root cause of quality problems. Selection should focus on whether the equipment supports touch-screen operation, multi-group parameter storage and other functions, such as JiuJu magnetization equipment can be based on the motor model one-click access to the corresponding magnetization program, while automatically recording the production data of each batch, to provide strong support for quality control.
