Electric motors for new energy vehicles have stringent requirements for magnetic field uniformity, and surface magnetic field testing is a core process for controlling the rotor’s magnetic performance—it is by no means an optional step. Issues such as insufficient magnet saturation, uneven pole distribution, incorrect magnet installation, and localized defects cannot be identified by visual inspection alone, yet they directly lead to increased motor torque ripple, worsened NVH, and reduced efficiency, thereby affecting the vehicle’s range and ride smoothness. Surface magnetic field testing scans the magnetic field on the rotor’s surface to quantify magnetic pole peaks, waveforms, and symmetry, thereby screening out defective rotors in advance and avoiding rework after final assembly. Jiuju’s online surface magnetic field inspection solution enables automated multi-point scanning, accurately captures minute magnetic field deviations, and simultaneously records inspection data to meet mass production quality traceability requirements. On production lines for axial flux motors and automotive drive motors, integrating surface magnetic field inspection after magnetization creates a closed-loop process that controls magnetic performance variability at the source, ensuring stable performance across high-volume motor production.
