Manufacturing process for E core decreases magnetic properties of the electrical steel (mechanical stresses, burrs, air gap, etc). Core loss can be higher by 20-30% than theoretical data indicated in catalogues of electrical steel core manufacturers.

Mechanical stresses are much lower in manufacturing process of toroidal cores compared with EI and C shapes.

Toroidal manufacturing process eliminates air gaps, burrs, and reduces core losses, even allowing to use magnetic core standard manufacturer’s data sheets.
