Worthington Steel Subsidiary Tempel Announces New Technology for Motor Core Lamination Bonding
FSB™ applies a thin adhesive layer to the laminations before stacking, creating a strong bond that helps eliminate gaps and improve motor efficiency. Compared with traditional motor core stacking methods, FSB™ is more efficient, durable and cost effective.
“FSB reflects the kind of innovation that strengthens our leadership in electrical steel lamination and helps customers deliver next-generation motor technologies,” said Geoff Gilmore, president and CEO of Worthington Steel. “This patent-pending process demonstrates how Worthington Steel and Tempel are creating more value for our customers.”
FSB™ offers several advantages versus traditional bonding technologies, including:
- Improved efficiency by reducing wasted energy inside the motor core (lower core loss).
- Quieter, smoother operation by reducing noise, vibration and harshness (NVH).
- Improved thermal conductivity, which may reduce hot spots and extend motor life.
- More active steel in each motor core thanks to thinner coatings (as little as 2–4 microns versus 5–14 microns with traditional methods), supporting greater efficiency and power.
- Durability proven in testing, including resistance to heat, fluids and high pressure.
- Simpler, more reliable production supporting faster stamping speeds, longer die life and flexible sourcing.
“FSB offers an efficient alternative to traditional bonding techniques by improving NVH, reducing core losses and simplifying the stamping process,” said Cliff Nastas, president of Tempel. “Early feedback from customers suggests it can deliver meaningful performance gains in electric mobility and other advanced applications, as well as improved supply chain resiliency, scalability and cost competitiveness.”
Validated in Tempel testing and customer trials, FSB™ is already approved for production applications at multiple automotive OEMs and represents an important step forward in motor core design and manufacturing. More information on Tempel’s Full Surface Bonding is available at www.tempel.com.
