Asynchronous Motor Rotor And Stator Lamination Production Process
Induction Motor Lamination Prototype

We can support customers in developing new prototype motors. In the induction motor lamination prototype process, commonly laser cutting and wire cutting silicon steel.
Motor lamination employs laser welding or glue bonding process to stack together. With a rapid lamination prototype lead time of 7-15 days, we prioritize efficiency without compromising quality, facilitating swift development and testing of induction motor prototypes for our clients.
For prototype customers with wire winding requirements, we also provide wire winding services. Please provide us with winding data, such as wire type, wire diameter, number of coils, winding method…
Asynchronous Motor Lamination Stamping

Lamnow uses progressive dies to stamp all stators and rotors. The mold has 5 rows that are made of tungsten steel. It can be stamped 100 million times.
Progressive stamping streamlines production by sequentially feeding the electrical steel strips through a series of dies, creating complex and precisely formed laminations with high efficiency. It is cost-effective for high-volume production.
For large-diameter of induction motor lamination, we also use compound stamping and rotary notching to punch stator and rotor lamination.
Our stator and rotor employ an interlocked process. Technicians can start by setting the desired inclination (rotor). The stator and rotor are then automatically stacked during the punching/punching process. The interlocking process is cost-effective for mass production.
For the stacking height exceeding 80mm, the customer can choose the welding options, and the welding slot has 2, 4, 6, or 8.

Induction Rotor Aluminum Die Casting

Lamnow provides aluminum die-casting services for induction rotors. We have various aluminum die-casting sizes and shapes, such as aluminum rings, aluminum rings with fan blades, and aluminum rings with end bars.
The material is aluminum ingot, and the height of the aluminum ring is 3mm-15mm. We can provide standard die-casting mold and also provide customized die-casting mold.
Using advanced stator winding technologies, we intricately wind copper wires around the stator’s core, ensuring optimal electrical performance.
Our automated winding processes guarantee uniformity and accuracy, reducing the risk of overheating and ensuring smooth operational performance.
Whether it’s for high-speed applications or heavy-duty industrial use, our stator winding process adheres to stringent quality standards.
The result is a meticulously crafted stator that maximizes the motor’s electrical output, longevity, and overall effectiveness in diverse applications across industries.

Quality Control For Asynchronous Motor Iron Core
- Verify the quality of the raw materials used in the iron core, such as laminations and insulation materials.
- Use CMM and 2D imager precision measuring tools to ensure that the stator and rotor laminations meet the strict tolerances.
- Inspect the laminations for any defects such as burrs, cracks, or delamination.
- Check the assembly process to ensure that the iron core is assembled correctly.
- Maintain detailed documentation of the manufacturing process and quality control inspections.

Induction Laminations FAQS
Induction motor cores are reliable, durable, and cost-effective. They have a simple design, require minimal maintenance, and are well-suited for a wide range of industrial and commercial applications.
Silicon steel is the most common material used for induction motor laminations. It possesses excellent magnetic properties, high electrical resistivity, and is cost-effective, making it ideal for reducing eddy current losses and low core losses in the motor.
As a motor components supplier, we also offer nickel alloys, cobalt alloys , and thin-gauge electrical steel to manufacture generators, transformers, and motor laminates.
Laminations help in breaking up the continuous path for eddy currents, which would otherwise circulate within a solid core. This interruption reduces the resistance to the flow of these currents, minimizing energy losses and improving motor efficiency.
Induction motors work on the principle of electromagnetic induction. When alternating current (AC) is supplied to the motor, it induces a rotating magnetic field, causing the rotor (usually a squirrel-cage rotor) to turn and produce mechanical output.
Yes, induction motors can be designed to run on both single-phase and three-phase power supplies. However, three-phase induction motors are more common in industrial applications due to their efficiency and performance.
