Worthington Steel, Inc. announced today that its Tempel Steel subsidiary has developed Full Surface Bonding (FSB™), a process for bonding electrical steel laminations which, when stacked together, form a motor core. The patent-pending technology is designed to improve performance and manufacturing efficiency in automotive and industrial motor applications.
FSBTM a new technology for motor core lamination bonding
FSBTM 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, FSBTM 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™ process vs. traditional technologies
FSBTM 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, FSBTM is already approved for production applications at multiple automotive OEMs and represents an important step forward in motor core design and manufacturing.
