New coating for next generation electric motors
The global supplier of industrial coatings and coil coatings Beckers has launched a new “BeckryCore” Core Plate Varnish (CPV) that boosts motor innovation and efficiency in the e-mobility industry.
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.
“As smaller and more high-performance electric motors are developed, they require more compact laminated cores,” says Johan Sandström, Managing Director of Beckers Sweden & Interim Managing Director of Beckers Germany. “Thinner coating is essential to allow more compact motors that enable the development of these new types of motors, while also enhancing motor efficiency and reducing manufacturer costs.”
Introducing the new coating
“BeckryCore” is a waterborne CPV that builds on Beckers’ extensive experience in coil coating applications and strengthens its position as a leader in sustainable coatings. It 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 and improving magnetic properties.
Another advantage is that the new coatings ensures excellent stamping performance, which means it doesn’t wear out the stamping tools or create dust during manufacturing compared with other coatings. The CPV is produced in Sweden and is available globally to electrical steel producers and ultimately electrical motor manufacturers.
Huge market potential in the electric vehicle market
“Our market analysis highlighted that customers required better performing CPV than what was available on the market,” says Johan. “This is why we developed an innovative product that can better meet customer need and help develop the next generation of electric motor. We see huge market potential for Beckry®Core as e-mobility applications will grow significantly in the coming years.”
The new coating is the outcome of collaboration between Beckers Sweden, Beckers’ central Long-Term R&D unit (LTD), customers and most major electrical steel companies. Beckers is approaching customers that coat electrical steel, including electric steel companies with their own coating line and companies that specialise in coating electrical steel.
