What Are Laminations in an Electric Motor?
Motor laminations form the core of an electric motor’s stator and rotor. They consist of stacked thin metal sheets that are either welded or bonded together, sometimes with a protective coating. Instead of using a solid metal piece, these thin laminations help reduce eddy current losses, which can generate excessive heat and cause electrical and magnetic inefficiencies.
For larger electric motors, laminations are made from materials such as cobalt-iron alloys, nickel alloys, silicon steel, or thin-gauge electrical steel. Due to material constraints and to minimize waste, segmenting motor laminations is often necessary during manufacturing. Electrical steel coils are typically limited to a width of 48 inches, making specialized equipment and expertise essential for producing large motor laminations.
Precision is key in every step of the process, from laser cutting or stamping the metal sheets to coating, bonding, or welding them together to create the motor core. Our high-quality motor laminations are used across industries such as industrial manufacturing, power generation, aerospace, and transportation, ensuring efficient and reliable performance in heavy machinery.
