Stamping Stator Iron Core Laminations

Stamping is a cost-effective method for high-volume production. When applied to the production of stator laminations, this process ensures the creation of laminations with exceptional accuracy and tight tolerances.

In addition, the stator core is to stack the laminations together according to the requirements of the drawings. To manufacture high-quality iron cores, qualified laminations need excellent lamination stacking techniques.

Our automation system manufactures stator laminations are a critical component of electric motors that apply in various such as industry machines, wind/fire power generators, EVs, etc.

Stamping laminations ensure high magnetic properties, reduce eddy current loss, and enhance motor performance.

Laser Cutting Stator Core laminations

Laser cutting is a highly precise manufacturing method that employs a focused laser beam to cut, engrave, or shape silicon steel sheets materials with exceptional accuracy.

This process excels at creating complex lamination shapes, making it ideal for applications that require specific geometries to optimize motor performance. It is a non-contact process, which reduces the material risk of contamination or damaged magnetic properties.

Laser cutting is a fast and efficient process. Our engineers and designers can iterate designs rapidly, accelerating the development process. It is suitable for both prototyping and small-scale production.

Materials Used in Stator Laminations

The quality of stator laminations is heavily dependent on the materials used in their construction. At our manufacturing facility, we need carefully chosen various motor lamination steel grades. We use the best domestic silicon steel sheet (silicon steel or laminated steel)0.10 to 1 mm thick as the primary material for stator laminations. This material exhibits high magnetic permeability, low core losses, and excellent electrical conductivity, making it ideal for motor cores. The use of electrical steel helps reduce energy losses and improve the overall efficiency of the motor.

stator Laminations FAQs

Stator cores typically comprise as many as thousands to hundreds of thousands of steel laminations. Fabricators produce these precise laminations using computer-controlled laser cutting machinery or punching and stamping dies.

The process of manufacturing a stator core involves continuously placing laminations side-by-side. The goal is to form a complete circular or ringed layer with the laminations. The process involves laying out each layer until the required length or number of layers is achieved.

They are essential because they reduce energy loss, improve motor efficiency, and help control the magnetic fields within the motor, resulting in smoother and more reliable motor operation.

Minimizing Eddy Currents

In an electromagnetic field, stator cores produce voltage called an eddy or circulating current, which can cause power loss and performance inefficiency. How much loss depends on several factors including frequency of EMF and density of magnetic flux. Insulating stator core laminations reduces the eddy current. Thin silicon steel plates are stacked on top of one another around the center, preventing eddy current flow. With the eddy current reduced, the stator core can maintain constant power, keeping your motor running.

Reducing Hysteresis Loss

The stator core’s electromagnetic field also causes a degree of magnetization known as hysteresis. The process of magnetization and demagnetization creates a loop. Lamination plates have narrow hysteresis loops, requiring less energy to magnetize and demagnetize the core.

Cooling the Stator Core

Solid metal pieces in stator cores may cause the stator core to overheat, increasing the risk of melting. Laminations reduce the amount of heat the core produces, keeping it cool enough to avoid melting.

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 the riveting, cleating, gluing, and self-bonding technique.

In the stacking process, after the stator laminations 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.

Stator cores are critical components in electric motors and generators, playing a fundamental role in their operation. Some common applications of stator cores include electric motors, wind/fire power generators, transformers, industrial equipment(pumps, compressors, and conveyor systems), electric vehicles (EVs), hybrid vehicles, aerospace, medical devices, etc.
