An improved silicon steel sheet has two lateral ends each having a side edge narrower than the width of the silicon sheet. The side edge has two end points linking respectively to two lateral sides of the silicon steel sheet to form two symmetrical slant edges for reducing tension area of the silicon steel sheet at the side edge. The slant edges and the side edges form two solder zones to anchor the silicon steel sheet for soldering at the initial winding stage and after the winding is completed.
