New coating enables boost in efficiency of electric motors
Electric motors have laminated cores that are made up of thin laminations of electrical steel. These laminations are coated on both sides to insulate them, which reduces magnetic losses. The coatings must also be heat resistant. Beckry Core is a waterborne core-plate varnish (CPV) that not only allows thinner coating than other products on the market, but also enhances electrical motor efficiency by reducing power losses in the core laminates (photo) and improving magnetic properties, says the company. — Beckers Group, Berlin, Germany
