Welded stator core for motors

Stator Core

The manufacture of the stator core is to stack the stator laminations together according to the requirements of the drawings. To manufacture high-quality iron cores, qualified laminations, excellent lamination stacking technique and strict process control are indispensable.

The precision of the fixture directly affects the quality of the stator core, the protection of the stator during the welding process is also very important, if molten steel during welding splashes into the stator slot, it will affect the winding process.  

STATOR CORE STACKING

The silicon steel roll that the laminations are stamped from often have variation from one side of the lamination to the other, the stacking process will accumulate this variation, as a consequence, the Motor Core will gradually bend, we called that thickness difference. 

The stacking process is not just a simple building block, the fixture and slot alignment bar are key factors. Some fixtures use several steel bars to form a circle. After the stator laminations and vent plates are placed in the fixture, use the slot alignment bar to make all the components neatly arranged. The mandrel with the corresponding diameter is a better fixture, which can minimize the deviation of each lamination while they are being pressed by a hydraulic press.

The Stator Welding process is a good way to ensure the solidity of the stator core, our highly skilled technicians and advanced equipment are the guarantees of our service quality. We can also stack the lamination by backlack technique. Finished stator cores ready to be wound are delivered to your workshop after rigorously inspected.
