What Are Electrical Laminations?
Electrical laminations are thin sheets of electrical steel stacked together to form a magnetic core. By laminating rather than using a solid core, eddy-current losses are reduced, efficiency increases, and components run cooler and longer.
Why Choose Stephens Gaskets?
- Reduced Eddy Current Losses: precision stamping and insulation coatings minimise energy waste.
- Improved Magnetic Efficiency: high-grade CRGO and CRNGO steels deliver low-loss performance.
- Lower Operating Temperatures: laminations run cooler, extending component life.
- Customisable Designs: E, I or bespoke forms in various thicknesses (0.1 – 0.65 mm).
- Noise & Vibration Reduction: burr-free edges ensure smooth, quiet operation.
- Certified & Traceable Materials: full documentation for regulated sectors.
Industries & Applications
Electrical laminations are vital across power and motion industries:
Materials We Use
We manufacture from premium magnetic alloys for every requirement:
Material | Typical Use | Key Benefit |
---|---|---|
CRGO (Cold-Rolled Grain-Oriented Steel) | Transformers | Directional flux efficiency & very low core loss |
CRNGO (Cold-Rolled Non-Grain-Oriented Steel) | Motors & Generators | Uniform magnetic properties in all directions |
Silicon Steel | General Electrical Applications | Reduced eddy currents and heat |
Nickel-Iron Alloys (Permalloy) | High-frequency transformers & precision instruments | Extremely high permeability |
Cobalt-Iron Alloys | Aerospace & high-power motors | High flux density & temperature resistance |
Amorphous Metals | Energy-efficient transformers | Up to 70 % less core loss than CRGO |
