Passing the magnetization test for automotive motors is merely a basic prerequisite; it does not guarantee that the finished product will meet performance standards. Post-magnetization, individual units undergo surface magnetic field testing, which serves as the final quality control check. This process focuses on three key metrics: peak intensity, which determines whether each pole is fully magnetized—insufficient intensity can lead to torque decay and reduced efficiency; angle to verify the direction, checking the sequence of magnetic pole arrangement and pole position accuracy; incorrect polarity installation or angular deviation can cause torque pulsation and NVH-related abnormal noises; and waveform to assess distribution, evaluating the uniformity and symmetry of the magnetic field; waveform distortion can affect the motor’s smooth operation and service life. All three metrics are indispensable, and spot checks alone cannot ensure batch consistency. Jiuju Automotive’s online magnetic field inspection solution for automotive motors enables automated scanning of the entire rotor surface, simultaneous quantification of all three metrics, automatic sorting of defective products, and full traceability of inspection data throughout the process, thereby safeguarding the quality of automotive motor mass production.

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.
