Stacked riveted iron core is the improvement of the traditional motor stator core structure, composed of multiple pieces of silicon steel sheet stacked; each piece of silicon steel sheet stamped corresponding matching pit and tab, and all the steel sheet pit position is uniform, relying on the upper piece of tab embedded in the lower piece of the pit to bite each other self-locking, the formation of no rivets, no welding, stacked riveted one-piece connection structure. Mainly used as various types of motor stator cores, especially suitable for large linear motor stator cores; can achieve the longest 2.4 meters of one-time molding, greatly improving the manufacturing quality and performance of large linear motor stator cores.
Stacked riveted iron core using silicon steel sheet stamping molding, in each piece of steel synchronously punched out pits and tabs snap structure; each piece of steel concave and convex position is identical, stacked pieces of the upper piece of tabs automatically snap into the next piece of the pit, relying on the material’s own plasticity of the bite self-locking, without the need for additional rivets, no welding, no bonding, automatically stacked into a whole iron core. The stacking is tight, the magnetic circuit is complete, and the gap is small, thus realizing low iron loss, low heat generation, low noise, and high structural strength.
With the advantages of high-precision stacking, low magnetic loss, low noise, low heat generation, etc., the stacked rivet cores are widely used in the fields of new energy automobile drive motors, servo motors, intelligent robots, electronic transformers, sensors, leakage protection switches, as well as compressors, motors, transformers, and reactors in household appliances. At the same time, it can also be made into miniature and shaped cores through self-punching stacked riveting process to meet the needs of various types of micro-motors and non-standard electromagnetic equipment.
