Electric scooter motors typically use an external rotor hub design, and multi-pole magnetization of the permanent magnets is key to enhancing power performance. Multi-pole magnetization increases the number of magnetic pole pairs on the rotor, resulting in more abundant torque output at the same rotational speed and providing greater power during acceleration and when climbing hills. At the same time, the reduced pole pitch minimizes torque ripple, leading to smoother operation and lower noise levels. Single-pole magnetization solutions suffer from low magnetic field utilization and insufficient torque density, making it difficult to meet the operational requirements of scooters for high torque at low speeds. Multi-pole magnetization, combined with online surface magnetism detection, allows magnetization and polarity verification to be completed in a single process, instantly screening out defective units with weak magnetism or incorrect polarity and ensuring consistent magnetic performance in mass production.
Jiuju Magnetizing for Automotive Electric Step Motors
The shipping area outside the workshop was a hive of activity. After multiple rounds of full-machine commissioning, simulated mass-production validation, and factory quality inspection, a Jiuju DC motor automatic assembly line completed all factory-out procedures, was loaded onto trucks on schedule, and is about to depart for the customer's production base, helping the customer's project advance production implementation on plan.
A fully developed automated motor assembly line can replace a large number of workers, with production capacity and consistency far exceeding those of traditional methods. This video explains the challenges of manual assembly and the key advantages of automated production lines.
