Capabilities For Laser Cutting Stator And Rotor Laminations

Laser cutting is a highly precise and versatile process that uses a laser beam to cut through a variety of materials. The process involves focusing a high-powered laser onto the surface of the material, which melts, burns, or vaporizes the material along the desired cutting path.

laser cutting motor laminations process

The rotor and stator lamination cores use high-grade electrical steel, typically silicon steel or non-oriented electrical steel. This material is carefully selected for its magnetic properties and low electrical conductivity.

Our engineers use CAD and 3D Solidworks software to design the precise shape and size of the laminations. This design is then converted into machine-readable instructions for the laser cutter.

The metal sheet is placed on the cutting bed of the laser cutting machine. The laser, guided by the programmed instructions, cuts through the material with extreme precision, creating the desired shapes for the laminations.

The freshly cut laminations may undergo post-processing steps such as deburring, cleaning, or surface treatments to remove any sharp edges or surface imperfections.

Benefits Of Laser Cutting Core Laminations


Laser cutting provides high accuracy and repeatability, ensuring consistent quality and tight tolerances for motor laminations, which is crucial for motor efficiency and performance.


Lasers can cut motor core stacks of complex shapes and patterns quickly and with minimal tooling changes, allowing for efficient customization and adaptation to different motor and generator designs.

Reduced Material Waste

The precise nature of laser cutting minimizes the amount of material wasted, leading to cost savings and improved sustainability in the manufacturing process.

Faster Production

Laser cutting is a fast process, enabling rapid production of motor laminations compared to traditional methods, reducing lead times and increasing manufacturing efficiency.

Clean Edges

Laser cutting produces clean, burr-free edges, ensuring smooth and consistent surfaces on motor laminations, which is crucial for minimizing losses due to eddy currents.

Minimal Heat Zone

Laser cutting generates minimal heat, reducing the risk of distortion or damage to the material, resulting in better overall lamination quality and performance.
