Steel lamination of a stator core coated with VoltatexAxalta Coating Systems has launched its next generation C5 electrical steel varnish – Voltatex 1250V. The company claims this is suitable for use in multiple applications including electric motors, small and medium power tool generators, traction motors and electric vehicles.
The company says this new product is designed to aid the manufacturing process of magnetic cores of electric machines thanks to its slitting, punching and welding properties. Once applied, the surface of the cured varnish layer is a glossy light grey that has improved scratch- and corrosion-resistance. The coating is a water based and chromium-free formulation as well as REACH compliant which also helps fulfil requirements for reduced environmental impact.
