Common Challenges of Magnetic Components for Automotive Electronics, Solution Ideas for Magnetizers

End-to-End Solution for Magnetization Automation

With the steady development of the automotive industry towards intelligence and electrification, the complexity and precision of automotive electronic systems continue to increase. As the core components of several key systems, the performance of automotive electronic magnetic components has an important impact on the quality and safety of the entire vehicle. From the drive motors of new energy vehicles, all kinds of sensors of automatic driving systems to in-vehicle communication equipment, magnetic components are widely used in various key scenarios of automobiles, just like the "central nervous system" of automobiles, transmitting key signals to help various systems operate stably and accurately. However, these components often face some practical challenges during the manufacturing process, and JiuJi magnetizers, relying on advanced technology, provide reliable support to meet these challenges.

The accuracy and consistency of magnetization is a key issue to be addressed in the production process of magnetic components for automotive electronics. Take automotive wheel speed sensor as an example, its working principle is to obtain wheel speed information by sensing magnetic field changes, and then provide key data support for vehicle anti-lock braking system (ABS), electronic stability program (ESP), etc. The sensor has strict requirements for magnetic field strength, uniformity and stability. The sensor has strict requirements for magnetic field strength, uniformity and stability. If there is a millitesla-level deviation in the magnetic field, it may lead to abnormal output signals from the sensor, making the vehicle control system deviate in its judgment, thus posing a safety risk. In addition, there are differences in the demand for sensor magnetic performance among different models and brands, so how to ensure that each magnetic component can achieve stable, high-precision and high-consistency magnetization under diverse demand scenarios is a topic that manufacturers need to address.

In response to these practical needs in production, JUJI magnetizers provide adaptable solutions. In terms of precision control, the machine is equipped with an advanced magnetic field feedback system, which monitors the magnetic field changes during the magnetization process in real time, and adjusts the size and frequency of the pulse current quickly and precisely by means of intelligent algorithms. This design enables the magnetic field strength to be controlled with an accuracy of ±1%, which provides a strong guarantee for the stability and consistency of the magnetic properties of magnetic components. In the case of magnetizing the rotor magnets of a new energy automobile motor, for example, JUJI Pulse Magnetizer is able to customize the magnetizing pulse waveform according to the magnet material characteristics, size specifications, and motor design requirements, so that the magnetic field uniformity of the magnets is better than the industry's conventional standards, which helps to improve the efficiency of the motor's operation and stability performance.

In the face of diversified magnetic materials and different shapes of components, JUJI magnetizers have good flexibility of adaptation. The magnetizing tooling of the machine is well-designed and can be quickly replaced and adjusted to accommodate magnetic parts of various sizes and shapes, ranging from tiny electronic component magnets to large motor rotor magnets. For the new type of high coercivity magnetic materials, JiuJi can output sufficiently strong magnetic field by optimizing the design of power supply, which can effectively cope with the situation that it is difficult to magnetize this type of materials, and achieve stable and efficient magnetizing effect.

In terms of magnetization efficiency improvement, JUJI magnetizers show significant advantages. The equipment adopts highly efficient capacitor energy storage and fast discharge technology, which reduces the single magnetization time to milliseconds, and significantly improves the production efficiency compared with traditional magnetizing equipment. In the production line of large-scale magnetic components for automotive electronics, JUJI pulse magnetizers provide strong support for the optimization of production efficiency by virtue of their high-speed and stable magnetizing performance, and help the automotive industry to continue to develop.
