Magnetizing the rotor of a motor is an extremely critical part of motor manufacturing and maintenance. For new motors, magnetization allows the magnets to "activate" and produce a stable magnetic field, allowing the motor to run; old motors can be magnetized to restore performance and reduce maintenance costs. In principle, it is based on electromagnetic induction and magnetic field energy conversion to rearrange the magnetic domains inside the permanent magnet. The process of magnetization requires strict process control and magnetic performance testing, high precision matching, uniformity guarantee, defect detection and control, as well as environmental adaptation are all challenges that need to be overcome. At present, there are many patents on magnetization devices, such as the patents of Jiangsu Coretronics and Shanghai HuXiao, which solve the problem of magnetization from different angles, such as reducing positional deviation and ensuring magnetic stability. In terms of testing, the high-precision data acquisition system of Jane Instrument Technology also provides an effective solution.

Magnetizing a motor rotor may seem like a simple operation, but it has a profound effect on the motor's performance, efficiency and stability. In the manufacturing process, controlling the magnetizing process and testing link can make the motor reach its design potential. In the future, with the development of technology, the magnetizing device and test system will continue to be optimized to provide strong support for the progress of the motor industry, and help more fields that rely on motors to achieve efficient operation.

Video Case Study on the Magnetization Process for Jiuju Irregular-Shaped Cobalt Magnets—Jiuju Magnetizer

September 12, 2026

Irregularly shaped samarium-cobalt magnets have complex magnetic pole configurations. Combined with the high-temperature resistance and high coercive force of samarium-cobalt materials, this makes them highly prone to issues such as magnetic field non-uniformity and uneven magnetization during magnetization, placing high demands on tooling and process parameters.

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.
