Large stator core for frame 630 motor

Stator Core

The 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. 

The manufacture of the stator core is to stack the 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. High-precision metal continuous stamping dies, high-speed stamping machines, and excellent professional Motor Core production personnel can maximize the yield of good motor cores.

STATOR CORE STACKING

The stator core stacking process is not just a simple building block. In this process, the fixture and slot alignment bar are key factors. 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 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, the motor cores will gradually bend, we called that thickness difference. Our 20-years experience in core stacking allows us to manufacture high-quality stator cores at a lower cost.

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