Laminations
Specialized Electrical Steel Lamination Services
Sotek specializes in electrical steel laminations, stacked stator cores, and rotor core assembly manufacturing for motors and generators. We offer high- and low-volume laminations in various forms to meet your business's needs.
What is a Lamination?
Electrical steel, also called lamination steel, silicon electrical steel, silicon steel, relay steel or transformer steel, is specialty steel tailored to produce certain magnetic properties, such as a small hysteresis area (small energy dissipation per cycle, low core loss) and high permeability.
Electrical steel is coated with insulating material to increase electrical resistance between laminations, reduce eddy currents, resist corrosion or rust, and act as a lubricant during die cutting. Various organic and inorganic coatings are used, and the coating used depends on the intended application. Sotek applies C5 and C6 coatings when required.
Lamination Services We Offer
We offer laser-cut laminations when applicable to lower volumes and prototypes. We also offer stamped laminations, tooling manufacturing and maintenance when higher volume laminations make financial sense.
