Stator Laminations Manufacturer In China

Stator laminations are thin electrical steel laminations that form the core of an electric motor’s stator. These laminations are stacked, welded, or bonded together to reduce eddy current flow in the core. The goal is to minimize power loss, reduce vibration, and noise in the motor..

Our company has professional technical personnel and a number of 25T – 300T press machines to produce motor laminations. Depending on your unique specifications, we can design a custom stator and rotor lamination solution.

Stamping Stator Iron Core Laminations

Stamping is a cost-effective method for high-volume production. When applied to the production of stator laminations, our progressive stamping, compound stamping, and single-slot punching process ensures the creation of laminations with exceptional accuracy and tight tolerances.

Stamping laminations ensure high magnetic properties, reduce eddy current loss, and enhance motor performance. The stator core is to stack the laminations together according to the requirements of the drawings.

Motorneo offers glue bonding, self-bonding, laser welding, tig+mig welding, riveting, and cleating to assembly stator stacks. 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.

Stator Core Lamination Prototyping

Motorneo offers laser-cutting and wire-cutting technology for stator lamination prototypes. We have multiple laser cutting machines and low-speed, medium-speed, and high-speed EDM wire machines.

Laser cutting employs a focused laser beam to cut, engrave, or shape silicon steel sheet materials with exceptional accuracy. Wire cutting involves using techniques like Wire EDM (Electrical Discharge Machining) to precisely cut electrical steel laminations for motors.

We specialize in laser cutting and wire EDM cutting for motor laminations, ensuring high precision and quality in manufacturing these crucial components. Our lamination prototype lead time is 7-15 days.

Materials Used in Stator Laminations

We use 0.10 to 1 mm thick silicon steel sheet (electrical steel or laminated steel)and 25μm amorphous alloys as the primary material for stator laminations. These materials exhibit high magnetic permeability, low core losses, and excellent electrical conductivity, making them ideal for motor stator rotor cores.

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(drones), medical devices, etc.
