Process For Electrical Steel Lamination Stacking

Motor core lamination stacking refers to the process of arranging and stacking thin metal sheets (lamination) to form the core of an electric motor. This process is crucial for optimizing magnetic properties and reducing energy losses.

stacking lamination process

We use laser cutting, wire-edm cutting, or stamping machines to cut the silicon steel sheets into individual laminations. The dimensions and shape of these laminations are critical for the final motor design.

Our technician cleaned the laminations to remove any contaminations or oils that could interfere with the stacking process and created the stack fixtures.

We use automated stacking machines or manual assembly, depending on the production scale and requirements. Our process employs precision gauge pins accurate to .0001″ for meticulous alignment. After achieving the desired stack height, laminations can be bonded or welded as needed.

If needed, we use hydraulic presses or clamps to compress the stacked laminations. They help to ensure a tight and uniform core structure.
