NBAEM high-performance permanent magnet products have a wide variety of applications, from electric motors on ships, aircraft and motorsport vehicles, to pump couplings, batteries, solar panels and NMR Equipment. Our diverse markets allow us to keep our technologies on the leading edge of innovation. Our custom magnet production and fabrication ensures that our customers receive magnet products that are specifically catered to their unique design requirements.

Lamination stacks are often used as stators or rotors in generators or electric motors. They can also be used as laminated cores. Lamination stacks are often made with nickel-iron or cobalt-iron materials to optimize costs and wear resistance. Both nickel- and cobalt-based materials are ideal for lamination stacks because they perform well in critical, heavy-duty applications, such as automotive, aerospace, and military settings.

Once you decide on an alloy, the laminations are laser-cut, notched, or stamped for precision, depending upon volume. Stacking fixtures are made to hold the laminations, which are then stacked to the correct height, with a tolerance of +/- 1 lamination. Precision gauge pins align each stack with accuracy up to +/- 0.0001 inches. Once the laminations are placed onto a stacking fixture, the laminations can be welded, riveted, or bonded together, depending on the application.

Our cobalt and nickel-iron laminations can be as thin as 0.2 mm thick. This dimension is important because thinner layers have better resistance to eddy current losses. Without lamination stacks, eddy currents can generate so much heat, causing poor performance and potential motor failure.

NBAEM ensures strict quality control, from raw materials through ready-to-use stacks. Our lamination stacks are essential elements in generators for aerospace, defense vehicles, medical devices, guidance systems and more. We help you customize your lamination stacks based on the specific materials or limitations required by your application. We can also create prototypes for your approval before mass-producing them for your project. Additionally, we offer a variety of machining options through our Grinding Department.
