End-to-End Solution for Magnetization Automation
Automated Magnetic Charging Integrated Solution
Magnetizing the motor rotor shaft is a core process in the manufacture of permanent magnet rotors, directly determining the motor’s magnetic field performance and operational stability. The industry predominantly uses a post-assembly, integrated magnetization process, which—compared to pre-magnetizing individual magnets—prevents misalignment of magnetic poles and damage from collisions during assembly, resulting in a more uniform and consistent magnetic field distribution. Before magnetization, it is necessary to confirm that the magnets on the rotor shaft are properly assembled and secured in place. The rotor shaft is then inserted coaxially into the inner cavity of a dedicated magnetization coil to ensure precise alignment with the center of the magnetic field. A strong, directional magnetic field is generated by the instantaneous discharge of a high-voltage pulse capacitor, causing the magnetic domains within the magnets on the rotor shaft to align synchronously, thereby achieving saturation magnetization. After magnetization, each piece must be individually tested for surface magnetic flux density, polarity, and uniformity to ensure performance meets specifications. Jiuju Motor’s rotor shaft magnetization equipment is compatible with rotors of various sizes and pole counts. It features precise and controllable magnetization parameters, integrated coaxial positioning, and in-line inspection capabilities, ensuring consistency in batch magnetization and meeting the mass production requirements of various permanent magnet motors.

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.
