<p>The toroidal core for magnetic circuits of electric machines and facilities consisting of the annular body (1), wound from insulated oriented anisotropic strips (2) made usually from silicon steel sheet. The annular body (1) is on its exterior diameter and/or interior diameter fitted with chamfered edges (5) made from one face or both ones (4) of the annular body (1). The chamfered edges (5) are advantageously made round with radius R and one surface of the strip (2) is made a system of shaped grooves (9).</p> |
