Motor core direct stacking process & large rotation process
The manufacturing process of motor stator and rotor lamination cores has a significant impact on the performance of the motor. In the production of motor stator and rotor lamination cores, the direct stacking process and the large rotation process are two different techniques, each with its own characteristics and application scenarios. 01 Direct Stacking Process The direct stacking process is a more conventional method, where the laminations are stacked directly on top of each other without any angular rotation. In a progressive die, during the rotor or stator blanking step, the laminations are directly punched into the blanking die cavity. Each lamination is fixed together by the protruding riveting parts on the laminations. The direct stacking process offers high production efficiency and cost advantages. 02 Large Rotation Process The large rotation process involves rotating the laminations at a certain angle during stacking to compensate for the cumulative errors caused by u...
