  3. E-Motor Lamination and E-Core Stacks


Electric motors of all sizes are the future. These successful components are not only important in electric vehicles, but also in growing sectors such as renewable energies and robotics. With high-quality electric motor lamination products and a comprehensive range of related services, Feintool offers its customers the perfect springboard.

Feintool’s electric motor lamination products are built for maximum performance. Whether they’re used in micromotors, electric vehicles, or large power plant generators, they feature a robust design and reliable operation, guaranteeing the best results. The selection offers the right solution for any quantity and includes laser-cut sheets for prototypes, combinations of laser-cutting, notching, and stamping, and stacks for greater volumes with high-speed stamping. From individual laminations to interlocked stacks for rotor and stator to single and multi-part sets, Feintool provides everything in optimal quality. The key technologies, including secondary technologies, all come from a single source. Feintool is also constantly breaking new ground in the field of electric motor lamination, with a key focus on the development of new technologies, materials, products, and processes. Feintool embraces a culture of innovation, ensuring that even highly complex individual laminations and interlocked stacks can be manufactured economically.

High-precision laser cutting

With precision of the cut down to a few hundredths of a millimeter, we produce electro lamination prototypes in thicknesses ranging from 0.10 to 1.00 mm. We can also produce small and medium-sized series for you in an economical way. What’s more, we manufacture spare and replacement parts, as well as special contours.

Flexible stamping and in-tool lamination core stacks

The stamping of loose sheet metal is the basis for an almost limitless variety of products. In terms of the dimensions of your components, there are virtually no limits. In-tool lamination core stacks with finished parts are likewise among our competences, while in-tool punch rotation makes it possible to incorporate a twist or sheet thickness compensation.

Seamless metal and plastic connections

Injection-molded slot insulators made of plastic are a worthwhile alternative to conventional paper insulators for electric motor components. With this process we manufacture windable components for you. The utmost quality is guaranteed – because stamping and injection molding take place under one roof and are perfectly coordinated with each other.

Fully equipped for welding, baking, and gluing

Our extensive technology portfolio is rounded off by the baking, welding, and gluing of stator and rotor packages.
