Three Generations of Magnetic Insertion Technology: Video of the Automatic Insertion Process—Jiuju Motor’s Automatic Assembly Line

Traditional manual magnet insertion relies entirely on experience and tactile sensation, resulting in significant positioning errors, inconsistent quality, and a high risk of polarity deviations—all of which have become major challenges in motor mass production. With technological advancements, the magnet insertion process has undergone three generations of upgrades, and automated equipment has completely transformed production methods. Today, the new generation of magnet insertion machines equipped with servo systems can achieve high-precision positioning within ±0.02 mm, eliminating the uncertainties associated with manual operation. Mechanized operations not only ensure stable assembly precision and zero errors in magnet polarity but also guarantee highly consistent performance across every motor. High-precision automated solutions have completely replaced manual operations, officially bringing an end to the traditional era of magnet insertion reliant on tactile sensation, and laying a solid foundation for both quality and efficiency in motor manufacturing.
