Electrical steel laminations
Brandauer manufactures high-quality electrical steel laminations for applications where efficiency, consistency, and performance matter most. Our precision-formed laminations help reduce energy loss and support reliable operation in demanding electrical systems.
Drive efficiency with high-performance steel laminations
Electrical steel laminations have slowly become thinner with more precise geometries, and this technical change has brought Brandauer right into the capability range with a particular focus on 0.1 – 0.35mm thick material.
Brandauer manufactures electrical steel lamination stacks, which are integral to running the world’s most important electrical machines. Whether it’s an EV or renewables generator, for sectors like automotive, defence and aerospace or even household appliances, Brandauer is relied on as a trusted lamination partner.
Design
Stator and rotor laminations designed and refined to stringent specifications.
Tooling
Bespoke or low-cost standard tooling options for all types of lamination stacks.
Thin Gauge
Specialism in thin-gauge lamination stacks, ranging from to 0.1mm to 0.5mm in individual lamination thicknesses.
Technology
WEDM manufacturing capabilities with 1 micron tolerances and laser cutting for lower volume, allowing the right process for every lamination project.
Product ranges
Brandauer designs and manufactures all types of lamination stacks. From stacks that can fit on the end of your finger right the way through to large scale motors for marine turbines. Alongside the extensive size capabilities, Brandauer can also produce loose, bonded, and interlocked lamination stacks in full and t-segment geometries, with a speciality in ultra-thin gauge laminations.
Stator and rotor laminations
Traditionally stacked, bonded/interlocked stator and rotor laminations for motors and generators, with the option to supply stator and rotor only and armature variants.
Segmented laminations
T-segment laminations are increasingly being used to maximise raw material utilisation and winding density.
Specialist laminations
A range of bespoke transformer and choke laminations, including EI, EE and T&U laminations. The range also extends to solenoid and shunt laminations and shims.
Lamination assemblies
A range of stacking options is available, including interlocking, bonding and welding, with a program of continued investment in the latest technologies, bonding processes and equipment.
Prototype laminations
In-house Wire-EDM capability for up to single micron tolerance laminations with access to laser cutting for a low-volume, lower investment lamination stacks.
Standard modular tooling for lamination stack development at medium volume
Brandauer have invested in three standard tools, which allow the rapid development of laminations from 10mm OD up to 150mm OD. Customers’ geometry can be customised into the standard tool architecture, meaning stamped laminations can be produced quickly and at the fraction of the cost of a full series production tool.
The future of motor lamination development
From electric motors to generators, the latest direction is clear-cut and simple: lighter, smaller, and even more precise. With innovation constantly reaching new peaks, being the best means pushing the limits of engineering.
Designers in the field of electric motors and generators are up against various challenging design considerations. Optimal performance, economy and durability are crucial, and to achieve this, designers are attempting to balance high strength, low weight, compactness and durability.
It is these qualities that Brandauer consistently mirrors in the manufacture of its laminations – laminations that make a new generation of electric machines perform with the greatest efficiencies. Brandauer stamps electrical steel laminations that are just 0.1mm to 0.5mm thick and consistently accurate to within just 20 microns.
